!
In case of doubts or questions please ask SMW-AUTOBLOK or
one of our authorized offices.
11. Maintenance
The power chuck must be maintained at regular intervals. Check
the conditions by measuring the gripping force with a grip force
meter (e.g. GFT-X with head M4 for 6 jaws).
Replace damaged parts with original SMW-AUTOBLOK spare parts
only.
Maintenance must only be carried out at spindle stop of the
machine.
10. Residual risks
The type of components (shape, weight, unbalance, material
etc.) has a large influence on the system “machine tool - chuck -
component”. For that reason there is always a residual risk.
These residual risks must be considered by the user and must be
eliminated by suitable actions.
9. Crash / damages of the clamping chuck
In case of damage to the chuck, for example, after a collision, use
of wrong top jaws or actuation with unpermitted operating data
the chuck has to be returned immediately for safety reasons to
SMW-AUTOBLOK for inspection.
8. Actuating cylinder
The actuation of the chuck must only be carried out by suitable
cylinders in accordance with safety precautions and regulations.
When installing the chuck on the machine with an existing
cylinder, be sure that the actuating force of the cylinder does not
exceed the max. permitted actuating force of the chuck.
If necessary, reduce the actuating force of the cylinder. Connecting
and adapter parts must be specified for permanent load. Adjust
and check the proximity switches for the stroke control before
starting production.
The adjusted operating pressure / actuating force must be secured
against unauthorized change (for example with a lockable pressure
regulator).
7. Jaws
Always use original SMW-AUTOBLOK top jaws. Jaws of other
manufacturers can cause damage to the chuck or accidents.
SMW-AUTOBLOK top jaws are permanently marked with the max.
allowed actuating force F and the max. speed n.
These values must not be exceeded due to the danger of accidents!
Top jaws must be mounted with socket head cap screws of class
12.9 only. Tighten with the specified torque.
Always ensure sufficient length of thread engagement (min.
1.25 x thread dia.)!
The mounting bolts must be checked for damage and wear in
regular intervals, and have to be replaced if necessary. They have
to be replaced not later than after maximum 100000 clamping
cycles!
At reduced actuating force, the max. speed must also be reduced
accordingly!
6. Max. data for actuating force F and speed n
The data for maximum actuating force F and maximum spindle
speed n are engraved on the chuck body.
5. Safety precautions for the machine
• The machine spindle must only start if the hydraulic pressure
in the cylinder is fully reached and the component is clamped
within the permissible working range.
• Chuck can only be opened when the machine spindle is
stopped.
• A signal must stop the machine spindle in case of a failure of
the clamping pressure and the workpiece must remain safely
clamped until the machine spindle stops.
• Repowering after a power failure must not change the original
clamping mode.
• During machining, the chuck and the clamped component must
be protected by safety guards of the machine.
• Opening the machine door must be possible only when the
machine spindle is completely stopped.
• Maintenance and actuation of the chuck must only be carried
out when the machine spindle is stopped.
2. Demands on operators
SMW-AUTOBLOK chucks must be installed, operated and
maintained only by qualified and regularly trained personnel.
1. Correct use
SMW-AUTOBLOK chucks work safely and trouble free if they are
used according to their specifications i.e. to clamp components on
turning machines.
Any other use can be hazardous.
12. Environment protection
Danger for environment when handling incorrect!
Incorrect handling of environment hazardous materials, especially
the disposal, may result in environmental damage.
• Always follow below instructions.
• In case environmentally hazardous material polluted the
environment always take suitable actions immediately. If in
doubt, inform the local authority about the pollution.
The following hazardous materials are used: Lubricants such as oil
and grease can contain poisonous agents. They must not pollute
the environment. The disposal must be carried out by a suitable
waste management company.
For a proper function of the work holding, use original SMW-
AUTOBLOK lubricant only.
4. Transport
Please use suitable lifting gear for product heavier than 16 kg!
3. Visual inspection
Please check the product for visible damage prior to use!

Description of function
The shaft chuck type W is available as a compensating or as a self
centering jaw version.
The shaft chuck type W has a retractable jaw carrier to allow
complete machining of shafts in one operation.
It is completely sealed and permanently lubricated by an oil bath.
The face driver is quick change with a taper for centering.
The chuck and the power operated face driver are actuated by a
double piston cylinder.
Conditions:
• The work pieces need to be faced and centered before loading
into to the chuck.
• Runout of the center bores to the clamping dia. can be max. (at
compensating jaw chuck).
The application: Complete machining of shafts in one setup
1. Machine clamping dia. (only necessary when using the self centering chuck):
The jaws are retracted. The component is clamped between centers and driven by the face driver. This operation can be eliminated if
the clamping dia. is already machined when the center bore is manufactured. This operation is not necessary when using the chuck
with fl oating jaws.
2. Rough machining:
The part is driven with the high gripping force of the jaws. High chip removal is possible.
3. Finish machining:
The chuck body is retracted. The part is clamped between centers and driven by the face driver. The complete outline can be
machined with perfect concentricity.

Clamping pressure
• Does the hydraulic pressure and the resulting grip force match the data engraved on the top jaws?
• Never exceed the values stated on the top jaws!
Speed
• Does the max. speed in the CNC program match the max. speed engraved on the top jaws?
• Never exceed the values stated on the top jaws!
Face driver
• Is the concentricity of the center point of the face driver correct?
• Is the locking nut tightened correctly?
• Retighten if necessary.
Imbalance
• Is there any vibration caused by imbalance?
• Increase the spindle speed to machining speed in small increments and eliminate imbalance if needed.

Checking of oil level
Attention!
• Regular maintenance is important for the safe function, long lifetime, precision and grip force of the chuck.
• Check the grip force of the chuck regularly with the SMW-AUTOBLOK GFT-X grip meter!
• Do not use any liquids that can damage or destroy the chuck seals!
• Make sure the coolant used will not damage or destroy the chuck seals!
Maintenance plan
* Advice for checking method: At lowest hydraulic pressure possible, the jaw carrier and the master jaws must move smoothely
without chattering.
Checking of oil level (horizontal and vertical use)
Refill oil (on horizontal machines)
1. Bring the oil refill plug to the12.00 O`clock position.
Jaw No. 3 will be in 9.00 O`clock position.
2. Open the oil refill and the oil level control plug.
3. Refill oil (CGLP ISO VG 68) until it flows out from the oil control
plug port.
4. Close the oil refill and the oil level control plug.
Attention!
Checking the oil level must be carried out only when the jaw
carrier is fully retracted!
Refill oil (on vertical machines with inverted spindle)
1. Open one (only one out of the 3) stop bolts.
2. Refill oil (CGLP ISO VG 68) until it flows out from the oil refilling
plug port (bottom edge of port).
3. Close the stop bolt port.

Attention!
• Wear of the seals can increase normal oil consumption!
• In case the refill volume exceeds the max values in the table below, the chuck must be checked and the seals must be changed.
