2. Work safety conditions
1. application
The power chucks with an integrated pneumatic cylinder and a fixed pressure distributor (attached to the
headstock) are designed for accurate turning of very long components such as tubes with large diameters and
similar workpieces.
Chucks can work on the lathes with a spindle, ensuring mounting of two chucks on its both ends. The double
spindle configuration increases clamping force and clamping stability.
The clamping/ unclamping is performed at stopped spindle by intake/ exhaust operation into the cylinder
chambers with a compressed air.
■manufactured from high grade alloy steel, which
extends machine life while providing higher rigidity
and greater wear resistance,
■hardened and ground working surfaces ensure
longer life with maintained accuracy and
repeatability,
■rigid structure and large through-hole,
■master jaws secured against throw-off,
■master jaws and drawbar lubricated directly,
Chuck technical features: ■built-in a non-return valve maintains a constant
pressure ow in piston chambers in case of
supply pressure drop
■air pressure safety control distributor in the
clamping chambers,
■jaw stroke control device,
■plain back mounting with clamping from the
front,
■external clamping of the workpiece (rapid idle
and slow gripping stroke)
■unbalance class G 6,3.
1. Please read the instructions thoroughly before
attempting to operate on the chuck and strictly
adhere to this manual.
2. In case of fault, malfunction or damage of the
chuck, immediately stop working and contact
technical supervision.
3. Repair and overhaul of the vise must be
performed only by an appropriately qualied
person.
4. Any set-up works, maintenance and all other
application work must be carried out at
stopped spindle and disconnected pressure
distributor only.
5. The max. data as max. pressure, max. speed
and max. gripping force are engraved on the
chuck body. They must not be exceeded in
any case.
6. Always use original BISON top jaws only.
7. Check the sealness of both cylinder chambers
regularly.
8. The steady pressure distributor must be
mounted steady on the chuck to eliminate
throw-off risk.
Except as listed above, the operator should follow
the existing local Health & Safety Regulations.
By following the instructions covered in this manual,
a long life and trouble free operation of the vise will
be guaranteed.
NOTE: The spindle rotation can be turned
on only when there is no pressure in air
supply hoses!
!NOTE: The manufacturer assumes
no responsibility or liability for any
claims arising due to not following the
instructions covered in this manual.
!
NOTE: The manufacturer reserves the
right to make improvements or changes
to the product without describing herein.
