Basic Information
These chucks without through bore can be used as a replacement for manual chucks on a conventional lathe to increase the productivity. These can be actuated by hydraulic, pneumatic or electro- mechanical actuators.The actuating unit imparts a linear motion of the wedge is transformed to radial movement of base jaws. This transformation provides a mechanical advantage of 1:4. This ensures a minimum of 1:2 mechanical advantage after providing for internal losses, self locking effect and losses in gripping power at high speed.: these chucks With Through Bore are designed to rotate at high speeds on CNC lathes. The compact construction of the PHNC Chucks offer further advantage of less weight and low inertia which have positive influence on the dynamic effect of CNC machine spindle.These chucks have a large through bore and are therefore suitable for bar work. The weight of the base jaws and top jaws are reduced in these chucks. This not only reduces the mass but also lowers the centre of gravity, thus minimizing centrifugal losses.
