GMT Manual Chucks offer a significant advantage over other types of chucks, especially scroll chucks. The conventional bevel gear and scroll in manual chucks have been replaced by a worm & worm wheel to operate the jaws. This arrangement significantly increases the mechanical advantage of the chuck and therefore allows heavier machining forces. The quality of the lathe chuck is a significant factor in the accuracy and quality of parts produced on a lathe. A GMT chuck enhances the productivity of the lathe resulting in considerably faster and more efficient production. CALL +91 87544 83577 or mail us at
