Power Chucks

power chucks

These Power Chucks, in which the jaws are actuated with hydraulic or pneumatic cylinders, are designed for use on CNC lathes. GMT is the preferred brand when it comes to workholding in India. Probably the reason why many leading OEM’s prefer GMT chucks.  CALL +91 87544 83577  or mail us at esales@gmt.co.in


These chucks without through bore are a good replacement for manual chucks on a conventional lathe to increase the productivity. Besides, the actuation of these chucks can be hydraulic, pneumatic or electro- mechanical.

The actuating unit imparts a linear motion of the wedge which, in turn, transforms into radial movement of base jaws. This transformation provides a mechanical advantage of 1:4. Consequently, 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 rotates at high speeds on CNC lathes. The compact construction of the PHNC Chucks offer further advantage of less weight. The low inertia has a 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 comparatively less in these chucks. This not only reduces the mass but also lowers the centre of gravity, thus minimizing centrifugal losses.

We have been a manufacturer and supplier of chucks for more than 5 decades in India. We have supplied over 55000 chucks to the Indian Manufacturing Industry. This has provided us with a valuable insight into the usage, maintenance and replacement of workholding products. Many a time we have come across GMT and imported chucks being replaced by cheaper brands. This leads to a loss of quality production and money in the long run. GMT PHNC-K can replace your existing Kitagawa chucks.

These high speed chucks with through bore are ideal for high speed machining with centrifugal compensation and less gripping force loss. GMT has designed the chuck to take care of the problems arising out of heavy centrifugal loss. Also, the design is such that the clamping force is very near to that of static clamping force, even at very high speeds. The base jaws are connected to counter weight by means of levers whereby the centrifugal losses arising due to very high speeds is compensated.
