Power Operated Three Jaw Chuck with Through Bore (PHNC) :
GMT Power Operated Hollow High-Speed Chucks rotate at high speeds on CNC lathes. The compact construction of GMT CNC lathe chuck offers the further advantage of less weight and low inertia, which positively influence the dynamic effect of the CNC machine spindle. These power chucks have a large through-bore and are therefore suitable for bar work. The base jaws and top jaws weigh less in these chucks.

Power Operated Three Jaw Centrifugally Compensated Chuck (PHCNC):
Standard power chucks will not work at the speeds used in CNC Lathes, because of the tremendous centrifugal force. At these speeds, the chuck will tend to loosen the job. More importantly, there will be an abrupt and huge loss in the gripping force of the chuck. When there is a loss in gripping power, it will adversely affect the cutting parameters of the lathe. Also, the design is such that the clamping force is very close to the static clamping force, even at very high speeds.
