Application; Work Safety Conditions - Bison 2502 Series Instruction Manual

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 lathe machine with spindle, ensuring mounting of two chucks on its both ends. The
double spindle configuration increases clamping force and stability.
The clamping/ unclamping is performed at stopped spindle by intake/ exhaust operation into the cylinder
chambers with a compressed air.
chuck technical features:
■ 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,

2. Work safety conditions

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 qualified
person.
4. Any set-up works, maintenance and all other
application work must be carried out at
stopped spindle and disconnected pressure
distributor only.
NotE: the spindle rotation can be turned
!
on only when there is no pressure in air
supply hoses!
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.
4
■ built-in a non-return valve maintains a constant
pressure flow in piston chambers in case of
supply pressure drop
■ air pressure safety control distributor in the
clamping chambers,
■ plain back mounting,
■ internal and external clamping of the workpiece,
■ unbalance class G 6,3.
6. Always use original BISON top jaws only.
7. Check the sealness of both cylinder chambers
regularly.
8. The pressure distributor must be mounted on
the chuck body 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.
