IMPORTANT
GENERAL INFORMATION
FOR THE BEST USE OF
THE MODEL 1.5 STUB BORING TOOLING
CAUTION:
Inner Spindle adjustment (see page 35) must be eorreet
for preeision use of stub boring
heads.
Since the extended Stub Boring Head design has eonsiderable overhang with
a small shaft diameter, the cutting tool ??Bil land must be kept very narrow,
(.005" to.015") (.tz?mm to.3s10mm) wide. This will insure best results with
no chatter at the bottom of the bore.
The small head will also be inclined to deflect with inereasingly heavy euts.
You may expeet, with properly sharpened tools, that after a .040" (f.bfOmm)
(on diameter) cut a seeond pass of ihe tool will remove elose to.001??(.OZSAmm)
material on the diameter. A seeond pass following a lesser first cut will remove
less metal.
The .040r' (f.Of6mm) cut will also leave a light drag back mark in the cylinder
that can in turn be eliminated by the seeond pass.
The drag baek mark is generally eliminated in any event by finish honing.
may also be eliminated by repositioning the boring spindle away from the
tool position on the return stroke.
It
You ean use the seeond pass performanee (second pass must be made without
re-eentering) to provide a most precise bore.
In general size variations in a typical cycle bore wiil approximate.000??i(.OtZZAmm).
A seeond pass will reduee these variations to generally less than half and
provide a fine finish. This finish wili require very little stock removal with
a hone in order to eross hatch for an exeellent ring seating condition.
The Boring Head assembly as noted in stub bar illustration, is equipped with
a dampening weight, part #600-8-2. This requires little or no maintenance
as long as liquids or eontamination do not enter the weight cavity. Should
this oecur, the operator will experience chatter problems with thii head and
it wili have to be disassembled and cleaned.
Performanee of the stub boring bar is also elosely related to the proper lubrication
and adjustment of the machine inner spindle bearing. Check the inner spindle
adjustment two to three times per year to make sure elearnaee is eoryeet.
CAUTION - It is very important that after inserting tool holder into the stub
Eoiing -uiter head anO pusning it firmly back to its" indexing point, that you
remove ail finger pressure from the tool holder and tool bit, before ioeking
-offset
it_ wltn its tocking set serew. This is especially important when using the
blind hole tool bit. Failure to follow the above instruction will result in size
variation.

NOTE: This micrometer is .050 to a revolution rather than .025 as on
a conventional micrometer.
Your boring bar mierometer, as with any other measuring tool, should be used
delicately and with eare, to be assured of great and continued accuraey.
Partieular attention should be paid to inserting the holder in the micrometer
without allowing the spring loaded tool bit to snap against the micrometer anvil.
Caution should be used to lightly lock the tool bit. Then turn the mierometer
spindle away from reading and firmly lock the tool bit. Then re-check
the micrometer reading.

Now raise the spindle out of the bore and insert the indieator. Make sure the
indicator lever is set properly so the dial will travel in the right direction.
Lower the spindie and adjust the indicator mount with either gooseneek, or tool
holder loek serew so the probe makes eontaet.
-22INST. FOR USE OF OPTIONAL MECHANICAL DIAL
Turn the spindle, and the indicator now will read the total runout. This will
be exactly double the distance the spindle is out of eenter.
To clean up a bore, it will be neeessary to set the tool about the amount of
this runout in addition to the basie bore size you measure. If you bump the
spindle unit lightly with your hand you will find you can easily reduee the reading
to near 0 for minimum stoek removal.
Similarly if the bore is substantially out of round or has seored wear grooves,
you may move the spindle so that you get two maximum equal dial readings at
the opposed large portion of the out of round.
Aehieving this you will find the bore will clean up on a slightly larger diameter
than you measure at the maximum out of round area.
Turn switch to clamp when you have the proper dial reading, remove the indieator,
and proeeed with the boring as usual.
If you wish to check the squareness of the bore faee, reset the dial indicator
lever for the proper travel direction and adjust the spindle and indicator to
eontaet the surfaee above the bore. Rotate the spindle then to check out of
square.
Remember, if you wish to eoreet out of square with shims under the work pieee,
you will have to use a shim proportionately larger (as the support points are
to the indicator travel extreme) than the out of square reading.

DEPTHS OF CUT
Proper cutting rpggg! are arranged so that the high speed range will rapidly
take euts up to .040" on the diimeter - up to 4r' diameters.
cuts that are taken over this size should be run on low spindle speed to prevent

CARE OF DIAMOND
If
the diamond wheel is handled with care

An abrasive stone is furnished with your diamond wheel for use in honing the
the face of the wheel. You should use this stone frequently to remove the
particles that tend to load this wheel, otherwise you will not produee the keen
edge on the tool that allows the machine to bore aeeurate holes with a fine
surface finish.

CAUTION: See sheet for tool sharpening requirement.
Diamond wheel is designed for earbide only and is not intended
rapid stoek

boring should
never alternately be used for cast iron or steel. Iron weld on top of
the bit will

CAUTION,
P.o not attempt to dress or sharpen the top of the toor
bit. Grind or dress the front and sides oniy.
TOOL LIFE
with tools sharpened to a precision edge, it should be possible

This applies to rnost American passenger ear bores under 4'r provided no
hard spots or foreign Insterinls are in the cylinders. The same number of
sleeving euts ean be made on low speed, without further sharpening. Provided
the tool has an original keen edge.
Two grades of carbide tool bits are available:

for prociuction re-boring.
CENTERING FINGERS
CHANGING OR INSTALLA?ION OF CENTERING FINGERS
CAUTION: Motor must be turned off and spindle cluteh lever must be in
the up detent position during any eentering finger oferation.
Centering fingers ean be taken o_ut by simply rotating the eentering knob eloek-wise
until fingers ean be removed. When lney -are replaced or reset in trre

CENTER ACCURACY CHECK
Centering fingers should be kept adequateiy aeeurate to center the new bore within
of the center of the worn hole. Centering fingers ean be iapped periodicatly
to obtain near perfeet eentering.
.002tr
Periodically check the eentering fingers by boring a hole and then without unclamping
the spindle unit, extend the fingers against the wall, checking to see that each
finger tip will lock a .001" shim. If the fingers will not do this they should

MICROMETER
Your boring micrometer, as with any other measuring tool, should be used
and with eare to be assured of the -greatest a""urae!. Particular attentiondelicately
should
be paid to inserting the tool in the mierometer without allowing tool bit
to
snap
into the mierometer anvil. care should be used in the methoolf ugntry roer<in[

tool bit before tightening
After a period of u-se you will note that the tool bit tip will foree a depression
in
the mike anvil' This, of eourse, will result in the ineonsistent
sizes, particularly after

exeessive loads are imposed on your boring bar the following oeeurs:
1. THRUST LOADS
If the bar is fed -or rapid traveled into
an objeet that imposes
exeessive thrust
load on the spindle, the bronze thrust nut, part number sbo-+t,an
will- probably be
sheared and require replaeing. This accident eould happen with spindle
either
rotating or stationary.
The effeet of this will be for the bar to continue to run but with no feed
or
down travel, drive spline will be pulled completely out of mesh at which point
motor will eontinue to run but feed serew wiil not turn at all. For replaeementthe
of the bronze thrust nut, 500-41, see Removal of Feed Sleeve and BearinE.
2. RADIAL LOADS
If the bar has a tool in the cutter head that turns into
the object, an exeessive
radial shock will be imposed on the spindle ano witt probably
motor drive
key,500-62. This would likely happen only when spinote drive;i';;
ciutch is in.
The immediate effeet of this wiil be for the motor only to run without turning
any visible parts of the boring bar. A movement of thl speed
lever will
indicate the iower gear box ii entirely inoperative. For replacu*"ni
"r,u"g"of the motor
drive key, 500-62, see Removal of Motor Fieid Assembly. i"r, aorupt ioads ihat

REMOVAL OF MOTOR HOUSING
To remove motor housing, remove sheet metal eover over spindle base, loosen
2 side serews in the spindle base, then take out 4 bolts in housing flange.
NOTE:
In reassembly, motor alignment must be checked after serew
sleeve is in place before flange bolts are permanently loeked.
Use surface plate over feed serew and spindle. Lightly
tighten the 2 side serews in the spindle base after alignment
is checked. Do not over tighten as this will cause the motor

COMMON CAUSES OF TROUBLE
(POOR FINISH, INACCURATE HOLES, EXCESSIVE TOOL
BIT HEAT, EXCESSIVE TOOL DRAG LINES, ETC.)
The great majority of these problems are a result of tool bit sharpening. Check
to make sure tool bit trB'' land is of proper width, with keen sfrarp faces and
that top of bit is free from flaws, with original rake angle and smooth finish.
Frequently a minute flaw, not visible to the naked eyu, "wiil prevent a fine finish.
It is possible dirt or lubricant used to elean outer spindle may enter lower eutter,
and the assembly containing a chatter dampening device. (soz-z-A,il. The resuit
of this would be to eneounter spindle chatter ai bottom of bore, particularly on
long bores.
Clean the inside of this assembly extremely cautiously and thoroughly, leaving
completely dry. Toleranees on these parts are extremely close an"d much care
should be used.
Hoies with inconsistent patterns and exeessive ehipping of tool bits in interrupted
euts at bottom of bore are an indieation of a looie inner spindle bearing.
A loose outer spindie bearing will not generally resuit in taper or inaecurate
bores, but can aliow spindle to drop stack in f-eed nut, resuliing in a mark in the
cylinder.
