QUICK CHANGE JAW CHUCK

GMT QUICK CHANGE JAW SYSTEM
Power chuck with a quick change jaw system
CNC Lathes are used particularly to machine small and medium sized batches. This involves frequent changeover of the chuck jaws which can be accomplished without undue cost by using chucks with quick change jaws. Power Operated Quick Change Jaw Chuck provides a super high speed range.

.
GMT is one of the leading power chuck manufacturer in India and has designed a power chuck with a quick change jaw system. This chuck helps in reducing the jaw changing time to a minimum. The wedge bars are designed to help counteract the effects of centrifugal force, and in fact this is done by setting them into the angled pockets in the body of the chuck. Moreover, the angles chosen by GMT for the piston shoulders and wedge bar teeth provide high mechanical efficiency ratio that provides for both sensitive and high pressure clamping. To withstand the most arduous working conditions, all PHQC chucks are designed with a high factor of safety. PHQC Chucks are operated by means of rotary cylinders controlled by proximity switches that provide signals concerning the state of the chuck i.e. clamping or de-clamping.

WORKING:
The Power chuck is different from other chucks. Its quick change jaw system has the inherent advantage for rapid resetting or changing of the gripping jaw. It is only necessary to release an eccentric locking pin with a special hexagonal key in each of the jaws keeping the chuck stationary. This disengages the gripping jaws which can then be reset to the required gripping diameter or can be reversed or can bereplaced by a jaw from another set. Turning the key again re-engages the gripping jaw and enables the key to be withdrawn and this operation provide great reliability.

.
PHQC chucks offer an effectively simple but technically advanced design to satisfy the high demands in both production and safety and modern machining. In addition the chuck offer a genuinely quick change jaw system with a speed and strength combination compatible with increased production and safety.
