and wheel much more than it would increase the number of pieces chucked; the result would be not a gain but probably a loss in production.
(
In arranging pieces on chuck, best results will be obtained if the ground surfaces
form a complete circle so the cut is continuous. The inner retaining ring should
always be used except for very narrow surface work or work having only a small
boss to grind, in which cases it is allowable to entirely fill the chuck.
Pieces having beveled edges must be blocked in such a way that they cannot ride up
on each other or on the retaining rings. In some cases square bars of cold-rolled
steel laid radially between the pieces may be necessary. Pieces with a single bevel
and to be ground on both sides, should be ground on beveled side first, thus ensuring a good surface for holding when grinding the other side.
Pieces too small for every one to span one or more brass rings wt:en placed close
together may be securely held by using a perforated brass plate. The holes in the
plate should be located directly over the brass rings in the chuck and should be
only large enough to allow easy placing of the pieces in them. The holes should be
smallest near the upper side of the plate thus giving a bearing as high up as possible on the pieces and reducing their tendency to tip when pushed side ways by the
wheel. The thickness of the plate should be only a few thousandths of an inch less
than the finish~d dimension of the work. The plate should be of brass or other nonmagnetic material in order not to absorb any of the magnetism. It should be centered by a plug or stops screwed to the chuck but should be left loose so it can be
lifted and cleaned with the work.
Pieces having bos ses or projections on the side next to the chuck Can often be held
magnetically by the simple expedient of placing soft steel blocks under the thinner
part to make the piece rest level,the bosses being in contact with the chuck. The success of this method depends on the area of the part in contact with the chuck, the
height and area of the blocks required and the location on the chuck. The pieces
must be blocked to prevent any side movement.
Non-magnetic metals such as brass, aluminum, and magnesium, can be held for
grinding if the parts are blocked to prevent side movement and shimmed if necessary. Sometimes blocking pieces having sharp pins or serrations acting like spurs
will hold the pieces down and prevent them from spinning.
Irregular shaped pieces which do not lend themselves to magnetic holding or blocking require some sort of mechanical clamping fixture. These fixtures are usually
fairly simple in design and need only light clamping pressure at fixed support
points to hold the piece for grinding.
Some non-metallic pieces such as rubber, plastics, carbon, graphite, and molded
articles are held the same as non-magnetic metals. Other parts glass, ceramics"
sapphire, etc. require different holding methods.
The holes in chuck face, plugged with brass screws to keep out dirt, are tapped into
the solid steel of the chuck body and are intended to receive screws for securing
fixtures and stops.
l
An adjustable stop is provided to limit the distance the chuck is moved under the
wheel when in the grinding position. When grinding work with a center projection to
be cleared, the stop can be set to stop the chuck short of the normal grinding position.
-9-
TRUING THE CHUCK: Whenever the chuck face becomes scratched and worn enough to
affect the accuracy of the work it must be refinished. The closer the limits to
which the work is held, the better must be the condition of the chuck face. A good
straight edge should be available to check for flatness.
,
For truing the chuck, use a soft, free-cutting wheel, such as Blanchard 91A24H8V.
Dress its face to be sharp and keen, turn on plenty of water inside the wheel and
bring it down gently onto the chuck face, with the chuck revolving at slow speed. It
should not be necessary to grind off more than .001" or .002" to clean up the chuck
face. The surface produced should be dull rather than polished, plainly show the
wheel marks, and should be free from any burned, glazed or spotty appearance.
Work pieces are less apt to slide on a dull clean cut surface.
If much metal has to be removed, rough dress the face of the wheel, just before
finishing~
to ensure a good surface.

SPINDLE ALIGNMENT: To produce flat work of uniform thickness the wheel spindle must
be exactly square with the chuck. and should be checked and made flat with straight
(
edge. All Blanchard spindles are set square at the factory, but may go out of flat
in shipping. The 3-point column support provides for a slight adjustment of the
spindle relative to the chuck, should this become necessary. The column is fastened to the bed at three points, A, shown in the plan view page 10.
Bushings threaded into the column and bearing on the bed provide slight vertical
adjustment at each of these three points. The base and column are separated by a
clearance of about 1/16" so that the bearing comes entirely on the three bushings.
Hold-down bolts pass through the bushings and are threaded into the base. The
heads of these bolts bear on large washers which rest in finished seats on the column and not on the bushings. These washers have a hexagonal portion and serve
to turn the bushings by means of projections entering slots in the tops of the bushings.
By slightly raising or lowering at these points, the column and consequently the
spindle can be tipped in any direction, an amount sufficient to restore the spindle
to its correct position. perpendicular to the chuck face, which should be nat when
checked with good straight edge.
When the spindle is correctly set from side to side, the wheel will cut both where
it moves toward and from the center of the chuck, giving a characteristic cross
marking. Using a straight edge it then can be checked for concave or convex which
can be corrected by the rear adjustment.

actual wheel marks on the work are of course much more numerous and close together.

GRINDING WHEELS FOR BLANCHARD GRINDING
Why Blanchard Makes Wheels
In the early days of Blanchard Grinding - back in the middle twenties - this Company had its own grinding wheel problems. The wheels we were able to purchase for
Blanchard Grinders were often not uniform in grade~ the available selection was limited,
and delivery dates often extenjed into the distant future. Because of these wheel difficulties, Blanchard Grinders frequently were restricted to a work performance which was
considerably lower than the maximum possible. In order to remedy this condition, and to
assure our Blanchard Grinder customers the best performance resulting from an always
available source of proper wheels, this Company decided to make its own grinding wheels.
The policy - and still adhered to - was to specialize only on wheels for Blanchard Grinders.
Our research and development work is continuous. Our objective is to produce wheels and
segments of highest quality. The raw materials used are the best obtainable. Our manufacturing methods and inspection procedures assure a precision product.
I
THERE IS NO BETTER WHEEL FOR A BLA..'CHARD
THAN A BLANCHARD WHEEL
CYLh'<DER WHEEL
The cylinder wheel is the most popular and generally the most satisfactory type
wheel for Blanchard Grinding. The proper Cylinder Wheel will stay sharp with little or no
dressing. Wear will be just sufficient to maintain this sharpness and no more. The grain
size will be so selected as to provide clearance for chips, depending upon the nature of the
material and the total area of the surface being ground, and as to produce the desired finish. The contact with the work is continuous with the maximum area of abrasive surface
in contact. The Cylinder Wheel should always be selected for fine finishes and where extreme flatness accuracy is required. Due to the broken contact surface, the Segment, and
to a lesser extent the Sectored Wheel, will often cause scratches on a fine finish and a
rounding off of the edges of the surfaces being round. It takes less time for a trained
operator to change a Cylinder Wheel than to install a new set of Segments; and, as against
resetting the Segments, there is only a wire band, in the case of the Cylinder Wheel, to be
cut and removed.
)
BONDS
The bond is the material used to cement together the abrasive grains and hold the
individual grains in place while they are in contact with the material being ground. The
bond must be strong enough to hold the grains firmly while they are acting as miniature
cutting tools; it must also be soft enough so that when a grain has become dull the added
resistance will break the grain or tear it loose, thus exposing fresh sharp cutting points.
Because of the large area of contact with the work, the importance of the bond in wheels
for Blanchard Grinding is apparent. In general a relatively soft wheel is required for
Blanchard Grinding. Of the various bonds used in the manufacture of grinding wheels, the
resinoid, silicate and vitrified bonds are most generally used in making wheels for Blanchard Grinding.
ABRASIVES
The abrasive grain material in Blanchard Wheels is either silicon carbide or
aluminum oxide. Three grain types of aluminum oxide are used: the tough, or regular;
/
-12-
(
semi-friable; and the white, highly refined friable grain. Each of these abrasives has its
advantages for certain kinds of work. Silicon carbide generally gives best results on materials of low tensile strength such as cast iron, chilled iron, brass, aluminum, bronze,
fiber, ceramics, and similar material.
Regular aluminum oxide is brown in color. It is a tough, strong grain, suitable for
grinding tough, relatively soft metals, such as soft low carbon steels and malleable iron.
The semi-friable aluminum oxide is more highly refined than the regular, but less
so than the white. It is intermediate in toughness between the two. It too is used for
grinding steel in the soft state. In combination with the white it is particularly effective
in meeting some grinding requirements.
The white highly refined aluminum oxide is the most useful abrasive for the general
run of Blanchard grinding. It is used principally for hardened or soft high carbon steels,
high speed steel, and hard alloys, and is the best general purpose abrasive for all materials.
The number used for designating the grain size or grit, corresponds to the number
of meshes per linear inch in the sizing screen. The coarser grits will generally give a
satisfactory finish for most purposes, and as they cut faster it is usually best to use them except when grinding materials such as chilled iron and hardened steel where the grain
depth of cut is limited and grits larger than 24 are not recommended. In fact, wheel wear
generally becomes excessive if grits coarser than 20 are used. The proper grit is generally dictated by the nature of the material and the area of the surface presented to the
wheel; the narrower the surface, the finer the grit; and the broader the surface, the coarser
the grit. Similarly, the harder the material, the finer the grit; the softer and more ductile
the material, the coarser the grit. The action of an abrasive grain in grinding is similar
to that of a cutting tool in machining a surface.
GRADE
The term "grade" as applied to grinding wheels is the measure of the hardness of
the wheel. The harder the grade, the more securely the grains are held and the greater
the force required to break them out of the wheel.
In selecting the proper wheel for a particular job, the following should be considered: the nature of the material, the dimensions of the pieces and total area being ground.
the amount of the material to be removed and the finish and accuracy desired. The effect
of material is expressed best in tensile strength - the greater the tensile strength, the
softer the grade required. Narrow pieces will take a harder wheel than broad surfaces.
That is, the broader the surface, the softer the grade. For rapid cutting, a wheel must
keep itself sharp by wear. Therefore, for rapid stock removal select a relatively soft
grade.
FINE FINISHES
Grits from 60 to 220 are used for fine finishes. The harder the material and broader the surface, the softer the grade required.
HANDLING AND STQRAGE OF WHEELS
The cylinder wheel because of its relatively thin section is more fragile than most
other types of grinding wheels. Care must, therefore, be taken in shipping, packing and
\.
-13-
unpacking, handling, and storage, or breakage may be expected. Wheels should not be
dropped or rolled along the flOur. Racks should be provided for storage of wheels. It is
usually more convenient to rack them vertically, that is with the axes horizontal. Proper
labeling will facilitate finding a desired wheel if several different grits and grades are
carried in stock. Wheels should not be stored in the open or in damp cellars. They must
be kept dry and extreme temperature changes avoided.
)
GRINDING COSTS
It should be pointed out that wheel costs are only part of total grinding costs.
Labor, overhead, and any burden charges to grinder and not included in overhead will
usually be the greater part of grinding costs. The rate of stock removal is a primary
factor in these costs, and it will often be found that a soft wheel, which may appear to wear
away too fast, will grind the work at the lowest overall grinding cost.
The following equation may be used to obtain the wheel cost per piece ground:
Cd
c = DN
c = \'''heel cost per piece, dollars
C = Cost of wheel, dollars
d = Wheel wear, inches of depth, in grinding N pieces
D = Usable wheel depth, inches
N = Number of pieces ground
A convenient method of obtaining the amount of stock removed is to subtract the
weight of the pieces after grinding from their weight before grinding, thus obtaining the
weight of the stock removed. IT this weight is divided by the weight per cubic inch of the
metal, we obtain the number of cubic inches of stock removed. While the weight of metal
varies according to its composition, the following weights per cubic inch will usually give
sufficiently accurate results:
Cast Iron
Steel
Aluminum
Brass
Bronze
0.256 Ibs.
0.2831bs.
0.0981bs.
0.305 Ibs.
0.3l61bs.
To obtain the amount of abrasive in cubic inches required to remove a given
amount of stock, determine the wheel wear by subtracting the total depth of cut or thickness of materi~ removed from the total down feed. Then divide this wheel wear by the
wheel wear per cubic inch of abrasive for the particular wheels used.
TRUING AND DRESSING THE WHEEL
Many wheel troubles will be avoided by bearing in mind that there is a most distinct difference between dressing a wheel and truing a wheel. This difference is particularly marked in the case of the Blanchard Grinder \VIleel.
To true a wheel is to remove material from the surface of the wheel so that at
grinding speed the grinding face will "run true".
-14-
"
~
To dress a wheel is to remove the dull abrasive grains from the cutting face or to
strip off a loaded or glazed face so that unused and sharp grain edges may cut upon the
work.
(
The Blanchard Grinder Wheel does not need IItruing" with a diamond or CARBORUNDUM stick and if it is done it will probably only complicate the trouble. Due to the
change in area of contact, the pressure per square inch between the wheel and work increases enormously when a high spot in the wheel face comes in contact with the work;
this great increase in pressure per square inch forces the grains of the high spot too far
into the work and they are torn out of the wheel, thus dressing off the high spot and truing
the wheel.
In the ideal grinding wheel the bonding substance is just strong enough to hold the
grains until they become dull.
When the efficiency of a grain becomes too low. that is, when too much power is
required to make it remove metal, the bonding substance breaks down and the grain is released. However, it is difficult always to obtain the ideal wheel and when a hard wheel is
being used (one that retains the grains after they become dull) or too fine a wheel (one that
fills and prevents grains from entering work) it is necessary to supply artificial means of
creating wear. This means takes the form of the wheel dresser and must be used at the
disoretion of the operator.
A work surface that is highly polished and appears to be divided into irregular
patches means that the wheel needs dressing. A wheel making a highly polished surface
is probably a little too hard (or too fine a grit) and should be watched carefully; if deep
scratches appear in the polished surface the wheel should be dressed. When using coarse
grit wheels on broad surfaces a wheel that is too hard will stall the motor repeatedly; if
reducing the feed does not prevent stalling or creates a highly polished surface, a freer
cutting or softer wheel should be used.
The Blanchard Wheel Dresser, however makes it possible to use a hard wheel
economically and without loss of productive time. If used only when the wheel requires
dressing, the Blanchard Wheel Dresser substitutes for the natural wear of the wheel; an
artificial wear under the control of the operator. Do not use dresser except when necessary; first experiment by changing feed and speeds.

CYLINDER WHEEL HOLDER
This cylinder wheel holder eliminates the use of wheel rings
and sulphur to mount cylinder wheels. The wheel holder provides the advantage of rapid wheel changes, and is especially
useful when the grinder is on production work, or where a
variety of work requires frequent wheel changes.
~
INSTRUCTIONS FOR USING
1. - Changing Wheels: - If the holder is to be secured to or removed from the face plate,
it is easier and faster to mount or remove the wheel on the bench. To change wheels with
the holder in place on the grinder, proceed as follows:
(a) Raise wheel guard as high as it will go.
(b)
With the table moved under the head, place the mounting board on the table
under the wheel and lower the head until the wheel is about 1/8" above the
board.
(c) Loosen the clamp set screws, fully retracting the clamps. The wheel will drop
to the board.
(d) Raise the head until the wheel is free of the holder and remove the wheel.
(e) Run hand around inside of holder and make certain that no clamp projects beyond its slot and check any sludge accumulation which should be removed.
(f)
Place the new wheel on the board and slide it under the holder, rais ing the head
as necessary.
(g) Lower the head, moving the wheel as necessary to gUide it into the holder. Continue lowering until wheel is against the face of the holder and the board has
been slightly depressed so that holder, wheel, and board turn together.
(h) Tighten the set screws turning them in equally and hand tight. It is easy to tell
when the center of the clamp comes against the wheel by the sharp increase in
force required to turn the screw. The set screw should be turned only slightly
beyond this point.
(i) Raise the head and remove the board.
(j) Adjust wheel guard.
2. - Parts and Accessories:-
(a) Clamps and Set Screws - The spring clamps are attached to the set screws by
means of a dovetail which is necessarily small. These screws have ample
strength to retract the clamps. The set screws are attached to the clamps
1/32" off center so that the clamps can only be placed in the slots with the wide
edge down. If the set screw does not line up with the tapped hole in the chuck,
the clamp should be turned over. It is not necessary to remove the clamps except for cleaning.
-16-
,"'"
(
(bl Wrench - Standard short arm hexagon keys must be used. The key for tIM< 1/2"
set screws has a 3-1/4" arm. The spring clamps are designed for the pressure
obtainable with these keys. The use of longer arm \\;renches or auxiliary
means of gaining leverage, such as a pipe. will only result in broken wheels.
(c) Mounting Board - This is a circular plywood board havmg the same diameter
as the wheel and with a brass plug in the center of the bottom side. With this
brass plug resting on the table, the use of the board assures that the wheel is
held evenly against the face of the holder. It also provides a flexible support
for the wheel. A cloth under the brass plug will avoid marring Ole table surface.
(dl
Wheel Guard - The wheel holders are greater in diameter than the corresponding wheel rings. Special wheel guards are available.
3. - \\beels: - Blanchard wheels purchased for use with the holder have the ",re banding
properly spaced and the Vellumoid strip cemented to the top of the wheel. The Vellumoid
strip is .050" thick and 3/4" to 7 /8" wide. This gasket material,s pressed into the wheel
by the clamps, the shape of the clamps resulting in an upward component against the face
of the holder. It also acts as a cushion between the steel clamps and the abrasive and
makes it possible for the clamps to firmly grip the wheel.
4. - l\laintenance: - As is the case with every piece of machinery, the holder should be
cleaned and lubricated occasionally, frequency depending on use. If difficulty is experienced retracting the clamps, it is an indication that the holder needs cleaning. The clamps
should be removed from the holder and cleaned. The slots and the holder face should also
be cleaned. Use a wire brush to clean the vertical tool cuts in the clamp faces and to remove any accumulated sludge between clamps. Put a small amount of Lubriplate 130A
lubricant on the set screws and the sliding surfaces of the clamps.
5. - Precautions:
-
(a) Use care in handling and storing wheels as they are brittle.
(b) Use only recommended wrench.
(c) Use care in getting wheel star:ed into holder.
(d) Always run hand around inside of holder to make sure that clamps are fully
retracted into slots, and check sludge accumulations.
(el Clean and lubricate holder as required.

BLANCHARD MAGNETIC CHUCKS
CONSTRUCTION
All Blanchard Magnetic Chucks, regardless of size, are of the same essential construction. The chuck body is machined from a solid steel disc. The top of the chuck body
is grooved and filled with brass to form concentric MAGNETIC POLES on the chuck face.
On the opposite side, concentric coil pockets are machined in chuck body, leaving heavy
walls between. These walls become the main poles of the chuck. The coils are sealed
into the pockets and a cast iron or steel bottom plate completes the unit. Both the chuck
body and bottom plate are ground flat to insure a water tight joint. The one piece steel
construction gives a body without joints and absolutely water tight.
I
Wearing Life of a Chuck.
On the outside circumference of Blanchard Magnetic Chucks is a shoulder, which
holds the outer chuck blocking ring, and indicates the wearing life of the chuck.

If the magnetic chuck does not become energized when the current is turned on,
there are many things to check.
Failure of D.C. supply at source.
Fuses blown.
Low voltage.
Loose connections.
Broken or short circuited leads.
\Vorn out or dirty brushes.
Weak brush springs.

Locating Fault in Chuck Circuit
Usually there will be either a short circuit, causing the fuses to blow, or an open
circuit so that no current flows when switch is closed.
Before starting to hunt for trouble in machine test outside circuit up to the switch
as the fault may be entirely in the outside circuit. If certain that fault is inside the machine, locate by testing each part of the circuit separately.
Machines which have rectifiers and Neu -t-rol chuck switches must be checked
thoroughly for trouble in these units.
If after thoroughly checking outside circuits trouble is not found, hoist out Magnetic
Chuck and inspect brushes and contact rings. (For No. 11 Machines new brushes are 1/2"
dia. by 1-1/4" long.) The springs should push the brushes up against the contact rings
with light, but appreciable pressure when chuck is in place. The contact rings should be
smooth and free from pits or burned spots. If pitted or burned, it indicates poor contact
caused by either brushes too short" weak springs, brushes sticking in holder. or oil or
dirt on rings.
If rings and brushes look all right, test with lamp of same voltage as chuck circuit,
or Volt Meter across brushes to see if current reaches thll; point. If lamp fails to light
properly, or voltage reading is off, check chuck cable from switch to brush holder, and ins pect brush holder.
If tests show no fault in circuit up to brushes, then it may be at contact rings. Disconnect chuck wires from contact ring holder and test for ground between rings.
If after testing complete circuit, trouble appears to be inside of chuck, we strongly
recommend the Magnetic Chuck be returned to us for repairs .

Testing Chucks
When testing the chuck units themselves, there are several checks which should be
made:
(1)
)
Be certain chuck is connected for same voltage as D.C. supply.
(2) Check entire chuck and each group of coils for proper readings as shown in
previous tables and sketches.
(3)
Check chuck for proper polarity. A quick test can be made by bending a piece
of soft iron wire or a paper clip around a pencil so it is free to rotate. The
wire should rotate in the same direction when passed over the chuck face,
making 1/2 turn over each main pole. If wire turns first one way and then the
other, reverse leads of one group of coils as shown in previous sketches.

ELECTRO-MATIC RECTIFIER
FOR MAXIMUM PERFORMANCE
)
The ELECTRO-MATIC RECTIFIER will deliver a steady flow of direct current to your
equipment within its rated capacity with practically no voltage fluctuation within the unit
itself. It is, therefore, suggested that this unit be connected to a circuit independent of one
with excessive variable loads. This unit will give many years of satisfactory performance,
providing it is connected and used within reasonable limits of its rated capacity. The A.C.
voltage applied to this RECTIFIER should be within 10'/0 of that indicated on the name-plate.
INSTALLATION
With the ELECTRO-MATIC RECTIFIER combination unit additional fusing or protective
devices are not required. The combination unit consists of the ELECTRO-MATIC RECTIFIER, wiring trough, switch, and fuse compartment. If you do not have the ELECTROMATIC RECTIFIER combination unit be sure a fuse disconnect switch is inserted in the
A.C. supply line to protect the RECTIFIER against short circuits of excessive over-loads.
All wiring to and from this unit should be well insulated to minimize the possibility of
grounds or short-circuits.
After connections are properly made to the A.C. and D.C. terminals of the RECTIFIER,
the half-wave rectifying tubes should be secured firmly in their respective sockets. The
anode clips should then be fastened to the terminal caps of the rectifying tubes or the
anode leads to the anode terminal posts. Check RECTIFIER for proper operation and then
replace cover and fasten securely.
ELECTRO-MATIC ELECTRONIC TIME DELAY SWITCH
This RECTIFIER is equipped with an automatic time-delay to ensure protection against
tube failures due to the application of the D.C. load before the rectifying tubes have reached
their proper operating temperature. The electronic time delay is factory adjusted and fully
automatic. Once adjusted, further attention is not needed, as it derives its control medium
from the D.C. output of the rectifying tubes, the ambient temperature and the applied voltage. A momentary voltage failure will not cause the time delay to recycle, it will act instantly within the operating temperature of the rectifying tubes. In the case of a sustained
A.C. voltage cut-off, it,will recycle only to the extent. to which the rectifying tubes have
cooled below their normal operation temperature.
The small variable control on the top of the chassis
(as shown at lower left) is adjusted at the factory with
the proper time allowance made for each model at the
standard voltage and need not be readjusted except
when tubes are changed or under certain voltage conditions. If the control must be readjusted, proceed as
follows: Turn the adjustment completely to the left and
then apply A.C. voltage to the RECTIFIER. The red
pilot light indicates the applied A.C. voltage. When the
emission starts at both tubes and full voltage is indicated on the voltmeter, wait 5 minutes and then turn
the adjustment slowly to the right until the relay contacts close. At this point the white pilot light (at left)
will glow, indicating that the D.C. voltage has been ap-

(
plied to the output terminals. The purpose of this control is to obtain the proper ti=edelay on a cold start and yet provide for an instantaneous reclosure of the relay in case
of a momentary A.C. voltage failure.
GUARANTEE
Each ELECTRO-MATIC RECTIFIER has been carefully inspected and tested under full
operating conditions before shipment. The RECTIFIER is guaranteed for one year. If
during that time repair or replacement is required due to defective workmanship or material they will be made without cost, provided the rectifier has not been subjected to
physical damage beyond our control.

Service Hints on Electro-Matic Rectifiers
If the A.C. fuses blow, any of the following could be the cause: A defective tube, a leaking
tube, a loose tube in the socket, or an excessive surge in the A.C. line voltage.
If the A.C. fuses continue to blow, look for the following: A loose tube, a worn out tube, or
a leaking tube. If the tubes were found to be loose in their sockets, they must be
removed and the contacts of the sockets thoroughly cleaned as well as the tube contact and replaced firmly into the socket.
Before replacing more than (2) fuses the condition of the tubes should be checked
or the tubes replaced with new ones. Before replacing however~ the contacts in
the sockets should be thoroughly cleaned and tubes screwed up firmly into their
sockets to assure good contact.
Loose tubes will have the following effect: The mercury will not properly vaporize with a
loose tube because there is insufficient current to properly heat the filament.
Use 2-EM-5 power tubes and 1-2050-8C time delay tube with model MT rectifiers.
When a tube is operated loose for a period of time, the contacts on the tube and the
socket will become pitted and carbonized. In this case, the tube must be removed
and the contacts of the tube and socket thoroughly cleaned, and the tubes again replaced tightly.
A loose tube because the mercury is not properly vaporized, will cause a flashover# which is equivalent to a momentary short circuit through the secondary winding of the transformer at intervals of seconds# minutes or even several hours.
Eventually it will blow the fuse, which to the operator would appear unreasonable.
This condition cannot be remedied by merely tightening the tube because as explained above, once the contacts are pitted and carbonized, no amount of tightening
of the tube would assure good contact.
If the transformer is damaged, the A.C. fuses will blow immediately upon closure of the
A.C. Line Switch.

See that fuse terminals and fuse clips are clean, that good contact is made between the
fuse terminals and clips~ and that the clips are securely fastened to the base.

Properly designed fuses warn you when poor contact exists. Charring of the ends of fibre
tubes or discoloring of metal ends always indicates poor contact on the fuse, or an overload. \Vhen only one end of fuse is charred or discolored, you have a positive indication
as to the end the poor contact ex.ists.
\Vasher or end plug on a ferrule contact fuse burned or partially melted indicates that the
plug was not screwed down tight.
If Rectifier appears to be operating satisfactorily. but fuses blow \,"hen time delay comes
in, which is indicated by the white pilot light, then check the following:
A short circuit in the D.C. wiring between the Rectifier and the :-lagnetic Chuck,
or a ground, or a short circuit in the l\Iagnetic Chuck. or associated equlpment.
If Rectifier appears to be operating satisfactorily, but time delay does not com" in:
Adjust screw driver slotted shaft mounted on the time delay chassis, turning shaft
in clock-wise direction. If this does not pull time delay in, replace control tube.
or check for an open circuit through rt!lay coil.
Proper timing of the time delay is essential to tube life and should be adjusted according
to data given on name plate. The timing will vary with the size of the Rectifier ranging
from three to 10 minutes. To decrease the time cycle, turn shaft clock\vise. To increase
time cycle. turn counter clockwise. The timing adjustment should always be made when
the Rectifier is started cold.

INSTALLATION AND OPERATING INSTRUCTIONS
NEU-T-ROL MAGNETIC CHUCK CONTROL
1I10dei E
GUARANTEE
The NED -T-ROL when operated according to instructions will perform indefinitely
with practically no attention and is guaranteed for a period of one year against defective
material and workmanship, during which time it will be repaired or replaced, providing it
has not been subjected to physical damage beyond our control.
lIIAINTENANCE
The NED -T-ROL requires no maintenance or adjustments other than an occasional
cleaning of the contact surface of the rotary switch. It is recommended that at periods of
from three to six months. the contacts be cleaned and a slight amount of vaseline applied.
This is not altogether essential. However, it will reduce wear and greatly prolong the life
of the contacts.
PROTECTION
The suppressor rheostat and all other current-carrying members are sufficiently
heavy to withstand considerable overloads. However, they cannot be subjected to short
circuits. The D.C. supply should be properly fused to protect the NEU-T-ROL in the event
a short circuit develops in the magnetic chuck or the wiring between it and the NEU-T-ROL
(It is not necessary to fuse the D.C. supply when the NEU-T-ROL is used in conjunction
with the ELECTRO-MATlC RECTIFIER as the line fuses supplying the ELECTRO-MATIC
RECTIFIER are of sufficient protection,)
For best performance, the D.C. voltage should not fluctuate more than 5'7'0 during
the demagnetizing cycle.
The NEU-T-ROL is arranged for a remote control. The main unit can be mounted
on some out-of-the-way part of the machine and the remote control station mounted fn a
convenient position to the operator.
Remove cever and make line and chuck connections and connections between the
main unit and the remote control station. A good grade of insulated wire should be used.
Four wires are used for the control switches and two for each pilot light. Make all connections as shown on the wiring diagram.
The red pilot light is connected directly to the chuck terminals and definitely indicates whether the current is on or off to the chuck. The white pilot light is interconnected with the residual limit switch and indicates the residual position.
OPERATION
The NEU-T-ROL Magnetic Chuck Control is fully automatic in its operation and
requires no attention or adjustment by the operator. The operator needs only to select one
of the three desired positions, namely; lion", "residual", or "off ll •
-32-
)
HEA VY PRODUCTION GRINDING
(
Assuming that all connections are properly made and the proper D.C. voltage applied to the NEU-T-ROL and the magnetic chuck, operate the NEU-T-ROL as follows:
For heavy production grinding, it is only necessary to operate the on and off switch,
leaving the power-residual switch in the "power" position. The on and off switch will fully
energize the chuck, depending on the applied D.C. voltage and will completely demagnetize
It when thrown to the "off" position. To load the magnetic chuck, the control switch should
be in the "off" position. After the work is properly placed on the chuck for grinding, throw
the control switch to the lion" position. noting that the power-residual switch is in the
"power" position. The red pilot light will indica'Le power to the chuck. After the grinding
operatIOn is ccmpleted, throw the on and off switch to the "off" position, and the NEU-TROL will begin its demagnetizing cycle. After several seconds, the work can be easily
removed. The work should net be moved during the demagnetizing cycle.
GRINDING OUT THE HIGH SPOTS FRO~I WORK THAT HAS BECOME
WARPED
Where it is necessary to perform llght grinding operations or grind out high spots
from work that has become warped, set the NEU-T-ROL in the lion" and "res idual" positions. In these positions, the work is not held to the chuck with the full magnetizing power
of the chuck, but rather with the resldual magnetism retained in the chuck and the workpiece, which is sufficient under ordinary conditions for finish grinding. To demagnetize
the chuck and the work-piece from this position, the on and off switch must be thrown to
the "off' 1 position.
GAUGING WORK BETWEEN GRINDING OPERATIONS
V\'here it is necessary to gauge work between grinding operations, as in cases where
a large number of small pieces are loaded on the chuck, and it is necessary to remove one
or more for gauging purposes between grinding operations, the power-residual switch
should be thrown to the "residual" position. This will allow the operator to remove one or
more pieces from the chuck without disturbing the entire lot. Upon replacing the workpieces, the power-resldual switch is again thrown to the "power II position and the grinding
operation repeated. DO NOT ATTE~IPT THIS PROCEDURE BY OPERATING THE ON
AND OFF SWITCH, AS THE NEU-T-ROL \V1LL RELEASE THE WORK SO THOROUGHLY
THAT WATER Al'm DIRT MIGHT SEEP UNDER THE WORK-PIECES AND THROW THEM
OUT OF THEIR ORIGINAL POSITIONS.
The red pilot light indicates power to the chuck and the white light indicates the
residual position.

Service Hints on the Neu-t-rol Control and the D.C. Supply
If the Neu-t-rol fails to operate or energize Chuck.
What to look for:
Check the D.C. supply voltage, which should be within 100/. of that indicated on the
name plate.
Check the Neu-t-rol Control name plate and that of the Magnetic Chuck to be certain that they are of the same rating.
Blown fuses; extremely low voltage in cases of an ineffective generator~ or a Rectifier operating on one tube supply half voltage at half wave.
Check the voltage fluctuation between "no load" and "full load". If there is more
than 10% variation in the voltage, it will greatly effect the efficiency of the Neu-troi.
An inoperative drive motor on the Neu-t-rol Control caused by worn brushes, worn
gears, or a loose coupling between the motor and the control.
If the Neu-t-rol unit operates but will not energize the Chuck:
Check to see if the red pilot light is burning on the remote control station, which
is connected directly to the Chuck terminals of the main panel. If this pilot light
is receiving current (be sure that it is not burned out), then a break in the wiring
between the Neu-t-rol and Chuck or a bad brush at the Chuck, is causing the difficulty.
If the Neu-t-rol appears to operate satisfactorily and energizes the Chuck but does not demagnetize:
What to look for:
An open suppressor rheostat caused by a previous short circuit in the Chuck or the
wiring between the Neu-t-rol and the Chuck, or if the Neu-t-rol continues to rotate
and does not stop at the selected position, there is a possibility of ground or a short
circuit in the wiring between the main Neu-t-rol panel and the remote control station; a ground or a short circuit in one of the control switches, or a sticking limit
switch in the main Neu-t-rol panel.
Breaking the D.C. supply either ahead of the Neu-t-rol and the Magnetic Chuck, while the
Neu-t-rol is in the full "on" position by other means than the Neu-t-rol is dangerous to the
Magnetic Chuck and should never be attempted. This practice surges the Chuck with the
possibility of puncturing the insulation and causing grounded Chucks, which can also break
down the insulation on the Neu-t-rol drive motor and burn out an excessive amount of pilot
lights.
The Neu-t-rol should never be left in the "on" position and the circuit broken by other
means to effect holding the work in position on the Chuck at the end of the work day or during the changing of shift. The residual position is provided on the Neu-t-rol for just this
purpose. Breaking the circuit by other means than the Neu-t-rol will cause surging of the
Chuck as explained abpve, and where a Rectifier without a time delay is used to supply D.C.
current, it would be necessary to start the Rectifier under full load without giving the
tubes a chance to warm up. This in turn could cause blown fuses or damaged tubes and
the possibility of operating on one tube.
-34-
,
The work piece cannot be larger than the Magnetic surface area of the Chuck to obtain the
maximum efficiency from the Neu-t-rol.

INSTRUCTIONS FOR ORDERING PARTS
This catalog covers all standard #11 Blanchard Grinders from serial #3028 up.
The illustrations show the various units and the important changes that have been made in
their design. Any part not shown is so designated in the text.
~
SERIAL NUMBERS: We number all our machines serially regardless of whether the machine is a #10, #11, ;/16, #I6-A, #16-A2, lIB or larger grinders and within the range
of serial numbers given in this catalog. There are other machines to which this
catalog does not apply; therefore, it is I:\IPORTAl'lT THAT THE SERIAL NUMBER
OF THE GRINDER BE GIVE=-< \Y1iEN ORDERING PARTS. The serial number is
stamped on the front of the Base near the controls of the Chuck Speed Box.
IDENTIFYING PARTS: We do not stamp our parts, consequently identification should be
made from this catalog. Any number found on gears is simply a lot number and
cannot be used for identification. Pattern numbers are sometimes left on castings,
and should agree with this catalog, but if not, they may be used if the number is
plainly indicated. Parts in this catalog marked "X" before the number simply
means that the part is not a casting, and if an order is telegraphed the "X" may be
omitted if the customer prefers.
STYLE PARTS: We designate small parts such as Screws, Nuts, Washers, Studs, Dowel
Pins, Keys, Threaded lengths of Pipe and Conduit, Grease Fittings, etc. as Style
Parts; for example, "Style 66 -#9" means a Woodruff Key. Style Parts need not
be mentioned when ordering as they will be included with the part immediately preceding them in the catalog. Style parts are identified on page 70.
BEARINGS: All commercial Ball or Roller Bearings and Thrust Bearings are listed by
the manufacturer's catalog number and may be ordered either direct from the
manufacturer or from us.
ARRANGEMENT: We have tried to arrange the illustrations and list of parts in the order
most likely to suit the customer's needs when ordering parts. Where there are
two or more designs of the same unit, the older design is listed first according to
the range of serial numbers which it includes. On some units where the changes
affect only a few parts, we have shown the latest and also give the number of the
older part in the description.

SETTING UP THE #11 BLANCHARD SURFACE GRINDER
The grinder can be easily lifted as a unit with a crane having 10,000 pounds capacity. This
is an easy method of putting the grinder in the proper position.
A basket sling is attached under the lip of the base and a hook placed in the cored hole at
the rear of the column. A spreader bar is used on the basket sling to prevent damage to
the water guards. This method of lifting is illustrated in photographs A, B, and C. A similar type of rigging can be used.
After the grinder has been set in the proper position it should be leveled from 3-points as
shown in the drawing on page 5.
A level is placed on the magnetic chuck and the grinder is leveled by plates at the 3-points
shown. After the grinder is leveled properly it can be grouted all the way along the
base. This is, however, not necessary. but prevents dirt, water. and oil from getting under
base and prevents odor. The grinder does not have to be bolted down.
After the grinder is properly leveled in position the alternating current power supply is
brought to the control panel. This supply should be approximately twice that necessary for
the main spindle motor. A direct current line is connected at the chuck switch if no rectifier is supplied with the grinder. The direct current, of course, is either 110 or 220 volts
D.C. and you should be certain before making such a connection that the magnetic chuck is
connected for the same voltage. If a rectifier is supplied with the grinder the only connection that will have to be made is the alternating current supply to the control panel.
)
At this point the rust preventive can be washed from the entire grinder and the machine
should be lubricated as shown in the chart and table on pages 6 & 7.
The alternating current power requirements are shown in the following table:
Machine
H.P.
Frequency
K.V.A. Rating
No. 11

50/60 Cycle

The grinder should now be started and the spindle and the chuck run idle for approximately
I hour before doing any grinding.

OPERATING INSTRUCTIONS
STARTING & STOPPING THE MACHINE: The machine is controlled from a central station with push buttons. The power feed lever and head raise and lower push buttons
are on the upper gear box. The push buttons and levers are clearly marked for
quick easy identification.
TYPICAL GRINDING CYCLE: Load work on chuck, close chuck switch, make sure work
is secure. Then with wheel high enough to clear work, traverse table to grinding
position. Start wheel spindle, start pump motor and select proper chuck speed.
Close water guard door and start chuck rotating. If necessary to change chuck
speed, stop rotating before shifting gears. Feed wheel down by hand until it
touches the work; engage down feed. Set rate of feed variator knob. Set feed dial
to feed predetermined amount. Check power consumption by ammeter while grinding. If motor draws too much overload. reduce feed rate. Overload relays are set
at approximately 1500/0 of full load amperage of 15 H.P. Spindle Motor.
If very accurate work is required, table should run a few revolutions after feed
trips before raising head.
Raise head either by hand or power. Turn off water, stop chuck rotation, and traverse table to loading position. Open water guard door and reverse chuck switch
then leave it in open position for removing work. The time the switch is left in reverse position is determined by the size of the work. The object of reversing the
switch is to change the polarity in the magnetic chuck and neutralize the residual
magnetism in the pieces. Remove the work from the chuck. Clean the chuck and
load it again as above.
Much of the work takes several minutes grinding time during which the operator
can wash work already ground and prepare pieces for loading.
It is advisable to allow the wheel spindle to run during loading time as on heavy
grinding this idle running helps cool the motor.
USE OF THE MAGNETIC CHUCK: All of the steel in the chuck face between and close to
the brass rings is magnetic when the switch is closed. Pieces of work should span
at least one brass ring to be held securely. Narrow or thin pieces will hold best if
placed in a radial direction, thus crossing as many brass rings as possible.
Stops of some sort must be used to prevent work from sliding.
holds pieces down but does not prevent them sliding, except by
piece and chuck face. Except for fairly large and heavy pieces
sufficient for safe holding and even on large pieces stops are a
The magnetism
friction between the
the friction is not
good safety factor.
The standard way of chucking small flat pieces is to place them close together between inner and outer rings laid on the chuck. These rings are usually of sheet
steel any convenient thickness less than the work.
Two rings are furnished with each machine, one fitting on the outside diameter of
the chuck and projecting 1/4" above its face, and the other a flat ring to be laid in
the center. The diameter of this inner ring represents what experience has shown
to be the best size of open space to leave in the center of the chuck. If this open
space were filled with work it would increase the arej!. of contact between the work

ELECTRICAL EQUIPMENT
AMMETER:
The ammeter is a Westinghouse AC Ammeter, Style NA-37 with special 0 to 160 percent dial and Blanchard Trademark. It is built into
the column just above the upper gear box. The ammeter is connected
to a Westinghouse type OC -133 current transformer with a 200 : 5
ratio.
MOTORS:
All standard grinders have two or three phase, 220/440 or 550 volt
motors.
The spindle motor is a 15 H.P. rotor and stator built into the wheel
head of the grinder. This motor is rated at 40 0 C continuous operation, and runs at 1200 RPM on 60 cycle current. (25 and 50 cycle motors run at 1500 RPM). Inquiries concerning these motors should be
made of The Blanchard 1>lachine Company, and should include complete nameplate data for the motor.
The chuck rotation motor is a 1 H.P. totally enclosed ball bearing
motor located near the pump well on the rear of the grinder. This
motor is Frame 182, and the motor is rated at 5SoC continuous operation and runs at 1800 RPM on 60 cycle current. (1500 RPM on 25
and 50 cycle.
Head raise-and-lower motor is a totally enclosed ball bearing motor,
Frame 182C, and is rated for 55 0 C raise on 5 minute duty. The
Torque is 8-9 Lb. Ft. starting and 3-3.6 Lb. Ft. running. Synchronous
speed would be 900 RPM on 60 cycles. (725 RPM on 50 cycle).
WATER PUMP
UNIT:
The water is circulated by a motor driven pump Brown & Sharpe Manufacturing Company No. 207. (The 60 cycle motor runs at 1725 RPM,
25 and 50 cycle motors at 1425 RPM). The pump unit is mounted in a
Pump Bracket - 17174, and is attached to the base by 2 Style 52A 1/2" x 3/4", and 2 Style 52A - 1/2" x 2-1/2" Cap Screws.
CONTROL PANEL: The Panel, mounted in the base of the machine, or in its own enclosure
on the rear of the machine, contains linestart contactors for all motors and thermal overload relays, and includes a control transformer
to give 110 volts to the push button. The Panel is built by us, or built
to our specifications, and replacement parts should be ordered directly from the manufacturer of the components, giving the type and catalog number, and giving the current characteristics of the machine and
the particular motor circuit for which the part is required .
