1. PREFACE :
Proper operational techniques and safety procedures will be explained in detail by our
technical staff. The general principles for safe operation of Ace CNC lathe are outlined in
this manual.
All Ace lathes have been engineered for operational safety. You will note, for example, that
all rotating parts are protected by specially designed covers and shields. The entire machine
is covered to eliminate damage by metal chips and cuttings and to prevent an insecurely
clamped workpiece from being thrown out during cutting operations. If the Ace lathe is
operated in accordance with the manufacturer’s instructions, it will provide you with reliable
service. However, with machines of this nature, serious accidents may occur owing to
improper or careless operation. Do not attempt to operate this equipment without having first
read and thoroughly understood the contents of this instruction manual. Not every example
of improper operation or unauthorized usage which may lead to malfunction or an accident
can be anticipated. If a particular operation is not documented in the manual as authorized
usage of the equipment, it should be assumed that this is an unauthorized or improper usage
with potential danger and should be avoided.
2. NOTES ON SAFETY :
1.
This machine is provided with various safety devices to protect the operator and the machine.
However, these cannot cover all aspects of safety, therefore the operator must thoroughly
read and understand this chapter before operating the machine. The operator should also take
into consideration other aspects of safety related to particular environmental conditions and
materials.
2.
Three categories of safety guidelines have been used throughout this manual :
DANGER, WARNING and CAUTION.
Their meanings are as follows :
DANGER :
Failure to observe these instructions could result in loss of life.
WARNING : Failure to observe these instructions could result in serious injury or substantial
damage to the machine.
CAUTION : Failure to observe these instructions could result in damage to the machine or
minor injuries.

3. CAUTION
Do not allow chips to accumulate during heavy-duty cutting since they will be hot and could
start a fire.
Check that the belts have the correct tension before operating the machine.
Warm up the spindle and the axis motion mechanisms before operation.
Write the program for the warming-up operation so as to execute the functions of the full
range of the machine components.
Do not operate the operation panel switches while wearing gloves as this could lead to
incorrect operation or other mistakes.
Follow the sequence for switching off, press emergency switch off the power switch on the
CNC operation panel, switch off the machine circuit breaker, then switch off the factory power
supply.
5. SAFETY ASPECTS RELATED TO WORKPIECE
AND TOOLING :
1. WARNING
Always use tools suitable for the work and which conform to the machine specifications.
Replace the worn tools immediately, since badly worn tools are a cause of accidents or
damage.
Do not operate the spindle above the rated speed of the accessories mounted on it. Before
starting the spindle, check that any parts which are clamped onto it are properly secured.
If the centre hole on larger workpieces held between centres is too small, the work piece could
come off when cutting load is applied. Make sure that the hole is big enough and that is at
the correct angle.
Take care not to catch your fingers in the chuck.
Always use the correct lifting gear for heavy chucks and workpieces.
2. CAUTION
Make sure that the tool length is such that the tool will not interfere with fixtures or other
objects. Perform a test operation after mounting the tool.
After machining soft jaws, check if they grip the workpiece correctly and that the chuck
pressure is correct.
1.5
6.SAFETY ASPECTS RELATED TO MAINTENANCE:
1. DANGER
Always switch off the main circuit breaker before carrying out any maintenance work. This
will eliminate the possibility of the machinery being started inadvertently by someone else.
After the power has been switched off for a short while, check the voltage with a multimeter
or similar instrument to make sure that there is no residual voltage.
2. WARNING
Always switch off the main circuit breaker before replacing bulbs or other electrical equipment
and use products with the same specifications as the original.
Maintenance of electrical equipment must be carried out by qualified licensed electrical
engineers only.
Do not remove or modify overtravel limit switches, interlock limit switches, proximity
switches, or other safety devices.
When carrying out maintenance in high places, always use a suitable ladder or a service
platform and always wear a helmet.
Keep your fingers clear of belts and pulleys.
Do not start the machine until all the covers removed for maintenance have been refitted.
Wipe up any water or oil spills immediately and keep the maintenance area and the workplace
clean and tidy at all times.
3. CAUTION

If one of the belts in a set has stretched beyond the prescribed limit, change the entire set.
Stop all machine operation before cleaning the machine or the surrounding area.
1.6
7. SAFETY ASPECTS RELATED TO THE WORK
PLACE:
1. WARNING
Immediately remove all water and oil spills from the floor and dry the floor to prevent
accidents.
Use strong service platforms only and make sure that nothing can slip off them. Keep
combustible materials well away from the work area or any other place where there are hot
chips.
Always provide sufficient working space and clear access to the machine and peripheral
equipment and store tools and other potential obstacles in a prescribed place away from the
machine.
Never place tools or other potentially dangerous objects on top of the headstock, turret or
covers.
Make sure that the nominal cross-sectional area of the power supply cable between the factory
power supply switch and the machine main circuit breaker is sufficient to enable a stable
supply for operation at the maximum output.
Protect all cables which will run along the floor from being damaged by chips, since this could
cause short-circuiting.
8. SAFETY EQUIPMENT :
This machine is provided with various safety devices to protect the operator and the machine.
The safety devices include interlock devices and emergency stop switches as well as doors
and covers. However it is absolutely necessary that the operator familiarises himself with the
instruction manual of the machine. It is essential that all operations be carried out in
accordance with these instructions. The manufacturer emphasises that it is the sole responsibility of the operator to ensure that all operations using the Ace CNC lathe are carried out
in complete safety.
Neither the manufacturer nor his representatives or dealers can assume responsibility
for any mishaps, damage or personal injury which may occur as a result of improper
operation or from failure to observe the safety precautions mentioned in this manual.
1.7
PREPARATION TO BE DONE BY THE CUSTOMER
PRIOR TO INSTALLATION OF THE MACHINE :
1.Environment (Machine side)
While installing the machine tool, avoid installing the machine in such places as mentioned
below.
a.
Places exposed to direct sunshine, close to heat sources and where temperature fluctuation is
considerable.
b.
Places where it is extremely humid.
c.
Places which are very dusty.
d.
Places close to sources of vibration.
e.
Places where the floor is not firm.
While installing the machine tool, the foundation should be firm and stable in order to maintain
the machining accuracy of the machine in the best condition. One of the recommended examples
of installation is shown on next page. However, as the foundation construction much depends
upon the condition of soil stratum supporting the floor of your shop, general counter measures for
the foundation of the machine tool should be taken.
When the floor of your shop is made of reinforced concrete having thickness of 300mm, it is
considered that the floor is firm enough to install this machine. The installing position should be
determined, considering the space around the machine so that the operator can remove the cover
for the maintenance of the machine, open and close the machine door and travel the carriage to
take out the cutting chips without contacting with other machines or bumping walls or the line.
Keep the environment around the machine clean at all times and do not install the machine where
it may be exposed to direct sunlight or heat source (heater).
FOUNDATION PROCEDURE FOR ISOLATING THE MACHINE
FROM SURROUNDING VIBRATIONS
In the case where the machine tool is installed out of necessity at a place close to vibration
sources, like hammers and presses, it is recommended to provide an isolated machine
foundation.
Please contact Ace Designers for further details.

1. LIFTING METHOD USING ROPES
The lifting arrangement of the machine is as shown in the figure. Remove the relevant covers
to sling the machine. Use a crane with capacity of at least 5 tons to lift the machine.
While lifting up, carefully check that the wire ropes do not touch the machine and provide
the portions where the ropes may touch with waste cloth or wooden pieces to prevent the
ropes from damaging the machine body.
NOTE : When lifting the machine, it is important to see that it is well balanced backwards
and forwards as well as to the right and left. Lift the machine a little above the floor and make
sure that it is well balanced before final lifting.
In case of lifting the machine by a group, proper co-ordination between the members of the
group has to be ensured.
3.1
2. INSTALLATION - CHECK POINTS
INSTALLATION SITE
The CNC machine should be properly installed in a location not exposed to direct sunlight. Care
should be taken to locate the installation site such that any chips, water, oil, or vibrations from
other equipments do not affect the lathe. Failure to observe these installation precautions may
result in serious malfunction of the machine. Improper installation can cause both numerical
control (CNC) error and loss of precision in machining operations.
Proper ambient temperature : 00 - 450 C.
Proper humidity : Below 75% Relative Humidity.
POWER SOURCE
The power source to the lathe should be free from any electrical noise produced by other equipment
such as electric welders or electrical discharging machines. Voltage drops and insufficient input
current can result in improper functioning of the CNC. An independent power source should be
provided if possible.
ELECTRICAL WIRING
a.
Connect the power line to the input terminals which are provided in the electrical cabinet of
the machine.
b.
The power source should be AC 415V, +10%, -15%, 50 Hz, 3 phase supply.(In India)
c.
Minimum gauge of the cable, from power source to the machine should be 10 mm2 . Separate
neutral and earth wires of 10 mm2 size are to be brought in.
Note : The machine should be earthed with an independent earth cable. We strongly insist
on the use of a 3Ø unbalanced voltage stabilizer at the incoming line.
3.2
3. GROUNDING
To prevent personal injury due to any abnormal current surges which may result from electrical
malfunction in other equipments, it is absolutely essential that all Ace CNC Lathes be grounded
independent of other equipment. If welding machines, electrical discharging machines, or the
like, are grounded to the steel framework of the building at the installation site, in no case should
any Ace CNC Lathe be grounded to the same steel framework. Malfunctions in electrical
equipment grounded in common with the Ace CNC Lathe may have adverse effects on the CNC’s
performance. Grounding wires should be as short and as thick as possible (use a grounding wire
of at least 10 mm2).
4. CAUTIONARY DETAILS CONCERNING
INSTALLATION
Provide a proper maintenance area.
1.
Make sure that all doors and panel coverings open and close freely without obstruction. Refer
to the appropriate installation diagram(s) in the manual provided with the Ace CNC Lathe.
2.
Make sure that the installation foundation is of sufficient strength and sturdiness. Refer to
the appropriate installation foundation diagram(s) in the manual.
3.
Ensure that the chip conveyor can be installed properly while accommodating the maintenance space. Refer to the appropriate installation diagram in the manual.
4.
All rust protective coatings on slideways which were applied for shipping should be
completely removed before beginning operations. Failure to do this can result in the actuation
of the servo-alarm when power is switched on.
5.
Before turning on the power, be sure to remove all fasteners and stoppers attached to the
carriage and the cross-slide during shipping.
6.
A number of internal cooling fans are fitted to each Ace CNC Lathe. It is imperative that the
installation site be located so as to prevent these fans from being clogged by dust or by mist
or spray from other equipment.
7.
When lifting the lathe, be sure to use only properly-rated cables, shackles and pipes. Refer
to the appropriate hoisting diagrams in the manual.
3.3
8.
After the lathe has been properly installed, use the Accuracy Test Results Chart shipped with
the equipment to ensure that it has been accurately levelled and adjusted so as to function at
a level of accuracy specified as being within the proper operating tolerances. Failure to do
so will result in serious loss of precision in machining operations.
Check the following before switching the power ON for the first time :
1.
Make sure that all bolts are properly tightened.
2.
Make sure that all high-pressure feed hosing and piping are securely fastened.
All Ace CNC Lathes are inspected and tested at the factory before being shipped to our
customers. However, possible mishandling or carelessness during shipment to the installation
site may result in misalignment or damage to the equipment. If left unchecked, this could
result in serious malfunctions later, such as vibration, CNC error, or oil leaks. To prevent the
possibility of this, it is essential to make a complete pre-operation inspection of the Ace CNC
Lathe.
3.
Power source:
Switch the power ON only after these points have been confirmed. At this time, once again,
check to make sure that all fastening and stoppers attached for shipping have been removed.
Do not begin operations immediately after switching the power ON. First operate the lub
pump manually to lubricate the slideways. Failure to provide proper lubrication can result in
seizing of the slideways.
After switching the power ON for the first time, check the following:
1.
Inspect for oil leaks. Make sure that all meters and gauges are functioning properly. Confirm
that the main pressure gauge is reading normally.
2.
Run the spindle, gradually increasing the RPM from low speed to maximum speed. This
should be separated into approximately five stages, operating at intermediate speeds at each
of the five stages for at least 20 minutes before eventually reaching the maximum allowable
RPM.
3.4
5. POWER ON / POWER OFF - CHECKPOINTS
The following checkpoints should be observed at all times during daily operations :
When switching the power ON, make a careful inspection of all the moving parts of the machine,
ensure that no one is standing close and that there are no obstructions. After switching ON the
power, check to make sure that the pressure gauges, lube pump, cooling fans, and other auxiliary
equipments are functioning properly. After the power is switched ON, do not begin operations
immediately. First operate the lube pump manually to lubricate the slideways and ballscrews.
Then activate each of the axes. Run the spindle for a period of approximately 15 minutes.
When turning OFF the power, observe the following order of operations:
1) Push the Emergency Stop Button
2) Turn OFF CNC
3) Shut OFF the machine power.
Do not leave the machine unattended with the power ON.
6. MANUAL OPERATIONS - CHECKPOINTS
The equipment should be operated only by one person at a time. It should never be operated by
anyone other than a trained operator who is familiar with the CNC Lathe.
If for example, one person is at the control panel operating the machine while another is replacing
the chuck jaws, the latter is liable to serious personal injury should the person at the control panel
inadvertently hit the wrong switch. If special circumstances make it unavoidable for two or more
persons to run the equipment, special care must be taken in co-ordinating activities to prevent
accidents.
Confirm that cutting tools and tool holders are securely fastened to the turret disc. Make sure that
these are fitted so as to be properly balanced and not to cause any interference or obstruction with
other parts of the equipment. Improper balance can have adverse effects on indexing cycle.
When performing set-up operations, be sure that the power is OFF. If it is absolutely necessary
to perform set-up operations with the power ON, take care before hand to set each switch located
on the control panel so as to prevent any accidents.
3.5
When using a scroll chuck, be sure to remove the chuck handle after using it to tighten the jaws.
Even if the spindle is stopped, the spindle will rotate slightly. This movement is more pronounced
on larger equipment. Be prepared for this rotation.
Always start rotating the spindle from minimum speed.
If any axis has moved beyond software overtravel, move the axis in the opposite direction and
then press the System Reset key. If any axis movement has actuated the Emergency limit, the
power to the drives will be shut off. Then keeping the Emergency over ride push button switch
pressed, jog the axis in the opposite direction till the emergency limit switch is released. Then
the emergency over ride push button can be released.
Optimum spindle speed should be calculated with due consideration to the specifications of the
particular chuck and chucking cylinder being used for the operation, and to the specific cutting
conditions.
7. MANUAL / AUTOMATIC OPERATIONS CHECK POINTS
Do not remove the protective covers or shields. Never attempt to insert a bar into the bore through
the spindle while it is rotating. This is an extremely dangerous practice with a high likelihood of
personal injury should the operator or portions of his clothing come into contact with the moving
parts of equipment and be drawn into the lathe.
When machining a bar, be sure to use the bar feeder and the guide bush. When a short bar is to
be machined, it must be of such length as to not protrude beyond the end of the spindle and the
guide bush must be used without fail. If the bar is longer than the spindle, it will be whipped
around violently with severe vibration.
3.6
Do not open the front guard or door while the spindle is rotating. Never open the front guard or
door to remove chips or cuttings or to gain access to the workpiece or the cutting tools while the
spindle is rotating.
Make sure that all rotating parts have come to a complete standstill before attempting to touch
them.
Never operate any Ace CNC Lathe with any of the safety devices removed. Be extremely careful
not to let loose clothing or hair get entangled in the moving parts of the machine. Be sure to wear
safety shoes or boots.
Be sure to keep the workpiece and cutting tools securely clamped at all times. Always begin
cutting operations at slow speeds and moderate cutting depths, gradually increase the feed and
depth of cut.
The operator should never stand in front of the spindle or other rotating parts. Particular care
should be taken during set-up operations or trial machining not to stand in front of the chuck since
there may be danger of the workpiece jumping out of the chuck jaws as a result of improper
clamping, and the cutting tool jumping out of the turret disc as a result of improper set-up.
During cutting operations, do not remove the chips by hand. Also, never attempt to touch the
chips directly with bare hands.
Never touch any of the switches or buttons with wet hands. This can cause short circuits or other
electrical malfunctions.
To prevent operational errors, operators should familiarize themselves thoroughly with the exact
positions of all the switches and push buttons.
3.7
8. AUTOMATIC OPERATIONS - CHECKPOINTS
When initiating operations for the first time under a new program, do not attempt to begin
continuous automatic operations at once. Keep the equipment in Single Block Operation (SBL)
mode and use other manual backup devices as appropriate to stop operations in progress as
necessary to check the effects of the program and to eliminate any bugs or undesirable machining
conditions found during trial runs.
Before replacing the workpiece with a new one, check that the Program-End lamp has turned ON
(indicating that the cutting cycle has been completed), and machining operations are actually
completed.
Be careful not to touch any of the push buttons or switches unnecessarily during automatic
operation.
3.8
9. LEVELLING
Before levelling, the machine base should rest on the levelling pads.
Fix the levelling bracket to the turret disc, as shown in the figure and place a spirit level on
the bracket.
Do a level check with the levelling bolts and foundation bolts tightened.
Level used
1 scale division
= 0.02 mm per meter.
Face size
= 150 x 55 mm
Keep the spirit level on the bracket.
Now, jog the Z-axis slide in both directions and adjust the levelling bolts so that the machine
is levelled both across and along the spindle axis. For levelling the machine across the spindle
axis keep the spirit level square to the spindle axis and repeat the same for different positions
of Z.
The bed should be levelled to get a reading within 2 divisions of the spirit level over the entire
axis length.
The level changes gradually depending on the condition of foundation, machine, etc. If the
above mentioned requirements are not satisfied the machining accuracy will be affected. So,
be sure to readjust the level atleast once every 6 months.
3.9
10. INSTALLATION AND MAINTENANCE OF
INTER-MACHINE CONNECTION
In order to maintain precision of machine for a long period of time and to operate it always
in the best condition, it is necessary to properly maintain the machine. Giving careful attention
to the operating state, conducting periodic inspection and replacing worn-out parts in their
early stage will prevent unexpected accident from happening.
1.
Maintenance immediately after installation
In the initial stage when the machine is installed, the machine is largely subject to change in
the bed level due to change in the foundation ground as well as to unstable solidification of
the ground, all of which have a serious influence on machine accuracy and at the same time
the machine itself undergoes initial wear and other changes. These changes possibly could
eventually affect the machine adversely.
While operating the machine, therefore, it is necessary to pay particular attention. Mentioned
below are points of caution as to the initial maintenance.
i)
Running in
After installation and when operating the machine for the first time, it is necessary to pay
particular attention to the machine before running in. Allow approximately 100 hours for the
running in. Avoid loading the machine heavily during the running in.
ii) Initial inspection of bed level
Check the bed level and the foundation for changes atleast once a month for a period of six
months after installation and, ensure correction of any disorder and always maintain the bed
level properly. After the six months, gradually extend the period between check as appropriate
depending on the changes observed, then carry out the check once or twice a year as it
stabilises.
3.10
2.
Inspection of inter-machine connection
Inspection of the state of electrical connections among respective units of the NC equipment,
the machine proper, the hydraulic unit, the control panel, etc.
i)
Loosened connectors
Check each connecting portion for loosening and tighten if so.
ii) Loosened screws at each terminal
Check electrical terminals of machine relay regions and each operation panel for loosened
screws, and tighten them as required.
iii) Check terminal screws and mounting screws of micro-switches for loosening and tighten
them.
3.
Inspection of electrical control panel
When inspecting the electrical control panel, be sure to turn off the main circuit breaker before
performing each check.
i)
Terminal screws and soldered portions
Check terminal screws of each electrical component for loosening and tighten them if
loosened. Lightly pull soldered portions of relay panel to check soldering strength.
ii) Cleaning
Dust and chips in the electrical control panel will lead to accidents. So vacuum clean them
with care.

1. STANDARD CHUCKS AND CYLINDERS
Standard 3 jaw / 2 jaw chucks (GMT)
Hollow 3 jaw / 2 jaw chucks (GMT)
Standard chucking cylinders (PRAGATI)
2. STANDARD CHUCK
DISMOUNTING AND INSTALLING PROCEDURE
If the machine is supplied with a standard chuck (GMT 3B/2B x 200), follow the procedure
given below to dismount the chuck.
a.
Put the chuck in clamping condition.
b.
Remove the jaws.
c.
Remove the centre piece.
d.
Remove the chuck mounting screw.
e.
Actuate the draw bar in out position. The chuck slides out from mounting flange.
f.
Hold the chuck firmly.
g.
Use the special Allen (or box spanner) supplied along with the chuck to loosen the draw bolt
completely. The chuck will slide out. Avoid hammer blows on the Allen key.
While following the above procedure it is suggested that the hydraulics be put OFF.
HOLLOW CHUCK : Insert a suitable rod inside the draw bar and unscrew the draw nut of
the chuck
FOR REINSTALLING FOLLOW THE STEPS GIVEN BELOW:
a.
Clean the chuck mounting surfaces with lint free cloth.
b.
If the chuck to be installed is a new one, it has to be dismantled, cleaned and greased as per
the recommended instructions of the manufacturer. Then the chuck assembly without the
hard/soft jaws and centre piece is to be mounted on the face plate.
c.
It is assumed that the relevant chucking cylinder and the corresponding drawbar is already
installed on the machine. If it is not done, the appropriate chucking cylinder flange and the
drawbar are to be fitted on to the chucking cylinder after cleaning the mounting surfaces.
5.1
Provisions for mounting the chucking cylinder flange exists on the face of the pulley on the
spindle. Clean the surface well and mount the chucking cylinder together with the flange
and the drawbar onto this surface. Check the alignment of mounting by dialling the reference
surface at the rear of the chucking cylinder. The total indicated reading (TIR) should be
preferably less than 0.04 mm to keep the spindle vibrations to the minimum.
Connect hoses to the input lines. The drain line should be directed downward and held in
that position to avoid tilting, thereby preventing overflow of oil from the drain chamber.
d.
Switch on the hydraulics and actuate the chuck clamp, the draw bar will be drawn in. Mount
the chuck in this condition. Engage the draw bar bolt into the draw bar and rotate the draw
bolt till the chuck is seated on the face plate. Insert the mounting bolts and tighten them
uniformly.
To set the clamping stroke, operate the foot pedal to release the chuck. Loosen the draw bar
till it just meets the resistance. This is the fully opened position of the jaws. Now tighten
the draw bolt by half a turn. Now the full stroke of the master jaws is available for clamping.
Operate the clamp/declamp switch/foot pedal to ensure the above. Then insert the centre
piece and fix it. Mount the hard/soft jaws suitably.
3. HOLLOW CHUCK INSTALLING PROCEDURE
This is almost similar to the mounting and dismounting of a standard chuck.
Following are the differences:
The draw bar is hollow and threaded to the piston of the chucking cylinder, and is prevented
from loosening by applying suitable thread locking compounds, which also prevents coolant
seeping through the threads.
The chuck being hollow, a draw nut is provided in it to fasten the draw bar. The draw nut
needs a special tool to rotate it (supplied by chuck manufacturer).
The chucking cylinder is provided at the rear with a coolant collector, (connected to the
housing) and a face seal is provided to seal coolant entry in to the chucking cylinder.
The chuck flange is not the same as that of a standard solid chuck.
5.2
4. STANDARD CHUCKING CYLINDERS(PRAGATI)
The hydraulic cylinders are suitable for operation of power chucks or collets. The cylinder
is mounted on the rear of the lathe spindle, and operates the job holding device through a
draw bar.
These cylinders have been designed with a hole through the entire assembly. The through
hole can be used to supply air or coolant to the work holding fixture. It is also possible to
use a length stop rod fitted from the rear of the cylinder to provide axial location for the
workpiece. This rod rotates with the spindle, but always remains axially stationary with
respect to the spindle, thus providing a positive reference point for job location.
The cylinders incorporate a non-contacting type of rotary joint, which is virtually free from
maintenance problems. This type of rotary joint gives a certain amount of leakage. The
leakage return tube should be of generous size and should be connected directly to the tank.
Cylinders should be mounted in the HORIZONTAL position, with leakage oil connection
pointing downward.
5.3
5. OPERATION AND ADJUSTMENT OF
HYDRAULIC CHUCK UNIT
The hydraulic chuck is opened by depressing the foot pedal and closed by depressing it again.
a.
If reduced jaw opening is desired then the draw bolt has to be adjusted after removing the
centre piece. The centre piece should be put back again after adjustment. For large
adjustments, the jaws have to be shifted on the serration on the master jaw.
b. Jaw change :
For jaw change, clean the serration of the master jaw and jaws, and the jaw nut fitting part
carefully, and then install with the same serration engagement as at the time of jaw
boring/turning.
c.
Adjustment of the clamping force :
Adjustment is done with the pressure reducing valve on the hydraulic power pack. Adjust
while observing the pressure gauge. After the adjustment, it must be locked with the lock
nut. The chuck pressure adjustment range is from 5 to 30 kg/cm2.
d. Change between Chuck Clamp / Declamp (by M codes).
To be used in MDI mode only and spindle should be OFF.
1. Select MDI mode
2. Enter M11 for chuck clamping
3. Enter M10 for chuck declamping
4. Press cycle start. The selected mode will be retained even after power OFF.
NOTE :
1.
For execution of M03 and M04 ensure that chuck is clamped properly before starting the
cycle.
2.
Change over from internal to external clamping should be done through I.D./O.D. selection
M codes i.e M16 for I.D. and M18 for O.D.
5.4
6. SOFT JAW BORING SEQUENCE FOR
EXTERNAL CLAMPING
1.
Install the soft jaws on the chuck.
2.
Set the hydraulic chuck internal clamping by parameter (M11).
3.
Use an inner diameter cutting tool to cut a hole (d) about 8 mm smaller than the workpiece
clamping diameter (D) into the soft jaws installed in the chuck.
4.
Set the hydraulic chuck external clamping by parameter (M10).
5.
Clamp a blank (outer diameter d-1 mm, length about 6 mm) in the hole (d) of the machined
soft jaws.
6.
Bore the soft jaws according to the clamping diameter (D) of the workpiece and remove the
blank after boring.
7.
Remove burrs.
NOTE : For detailed explanations regarding the hydraulic chuck, refer to the instructions
issued by the chuck manufacturer.
5.5
7. SPINDLE SPEED AND CHUCKING FORCE
1) Maximum chuck operating force :
The chucking force of the chuck may be decreased by the influence of centrifugal force in
proportion to the spindle speed in case of O.D. chucking. However, in general, the maximum
speed is defined as that speed at which the dynamic chucking force becomes a half of the
static chucking force when the standard jaw is used under ordinary condition and chucked
with a suitable cylinder.
2) Spindle speed and chucking force :
The decrease of chucking force against operational speed is shown in figure. The top jaw
is the standard jaw and at the maximum operating position. This value is, however, the
normal case and care must be taken because it generally varies depending on the adjusting
position of top jaws, size of jaw and cutting conditions.

3. LUBRICATION
Lubrication is very important for machine tools since it greatly affects machine life. Use
only recommended lubrication oils which can clean and free foreign matter. Periodically
clean the tank and filter, inspect equipment or piping for damages to ensure optimum machine
operation.
a.
SPINDLE
The headstock houses the spindle in bearings which are lubricated for life with high grade
grease (KLUBER ISOFLEX NBU-15). This grease can withstand low and high temperatures (-60o C to +130o C).
Spindle should be warmed up for approximately one hour when the machine has been
stopped for a long period (e.g. five days or more on account of holidays etc.).
See Cautionary details concerning Installation
b.
TAILSTOCK
The tailstock quill is connected to the central lubrication system. If the tailstock contains a
built-in live centre, then it is lubricated for life with KLUBER ISOFLEX NBU-15 grease.
It needs to be changed when the bearings are to be changed. If the machine is with add-on
revolving centre there is no lubrication required.
3.1 COOLANT
A tank serving both as a coolant tank and a chip tray (or optional chip conveyor) is installed
in the front side of the bed. It can be removed from the front side of the machine. Therefore,
it is easy to clean the inner part of the tank and to dispose chips. (Capacity 130 litres)

3.2
CHUCK
Selection of grease depends on the chuck used. Never fail to supply grease once a day to
the slideway of master jaw.
For GMT Chucks, it is recommended to lubricate the chuck once every shift. Use DOW
CORNING GN PLUS, MOSIL BRB 100, MOLYKOYTE BR 2 GREASES.
DO NOT USE OIL FOR LUBRICATION.
3.3 CENTRALISED LUBRICATION
The X & Z slideways, ballscrews and the tailstock quill are lubricated by automatic
centralised lubrication. Each point of lubrication is connected through a metering cartridge
of 0.25cc capacity/stroke. The provision for manual or automatic selection of lubrication is
provided on the control panel, and the lubrication interval is usually set at once for three
seconds for every 30 minutes.
It is recommended to supply enough number of lubrication shots by manual means before
starting a machine which has been shut down for a long time. The number of shots required
to fill the drained out lubrication lines after the lubrication metering cartridge depends upon
the distance from the metering cartridge to the lubrication point.
For further details see annexure - Centralised Lubrication.
3.4
DAILY INSPECTION
By opening the rear door the lubrication oil distributor mounted beside the X-axis feed motor
is monitored. Visual inspection of the distributor is not sufficient, so check oil at places
where oil is distributed (such as slideways). (e.g. Touch the slideways to check for an oil
film.)
Especially when the machine has been stopped for an extended period, the distributing pipe
gets drained. There are cases when the oil does not flow even though the pipe is filled with
oil. In such a case, check for oil flow by disconnecting the pipe.
If the machine is operated without supplying the lubricating oil to the sliding surfaces, it will
cause seizure of the sliding surface. Be sure to perform the above mentioned inspection
every day.

In case of axis misalignment of the spindle with respect to the Z-axis, follow the method given
below for resetting:
1.
Remove the chuck, chucking cylinder etc.
2.
Mount the inspection mandrel.
3.
Open the left hand guard covering the head stock.
4.
Loosen the mounting bolts of the head stock slightly and use the screws provided to align
the axis with respect to the Z-axis.
5.
Tighten the clamping bolts and recheck the alignment in both primary and secondary planes
of the Z-axis.
6.
