Gmt Hand Operated Chuck

We are offering gmt hand operated chuck.
Advantages :
because of the comparatively small number of well designed parts used in the chuck, frictional losses are reduced to minimum. The worm, wormwheel and the circular cam give the chuck an amazingly high mechanical advantage resulting in a grip many many times more powerful than that of a scroll chuck, for the same effort applied at the chuck key. Appropriate cam rise, combined with worm drive, ensures self locking action of the chuck over the entire clamping range and this guarantees the safety of the operator.
the top jaws are positively located on the base jaw by serrations ground after the jaws are case hardened. The top jaws can be quickly reset for different sizes of work pieces by merely loosening two socket head screws, shifting the jaw to the appropriate serration and re-tightening.
three jaw chuck of sizes from 125 mm dia. To 315 mm dia. Are offered with serrations of 1.5 x 60o on the base jaws.
sizes 400 mm dia. To 800 mm dia. Are provided with 'v' serrations of 332" x 90o.
