Chuck, Eccentric Compensating Type

GMT eccentric compensating chuck with retractable jaws and face drive (PER) is used for machining forgings and black bars between centres in single setup, ie, no second operation is necessary. This chuck is designed to machine components centre to centre with great accuracy. The retractable jaws are actuated by a hydraulic cylinder and also centre to centre, since the jaws have an eccentric clamping drive. After various machining operations are done on the component, without stopping the machine the clamping jaws are retracted. The torque is then transmitted through the face driver for driving the jaws. The gripped portion can now be finished with fine depth of cut. This ensures that the component is machined right up to the chuck face and the centre to centre machining of component is completed. The chuck body is made from forged medium carbon steel and toughened. The levers and hinge pins are made from nickel chrome steel, case hardened and ground in all working surfaces. The hard jaws are made fromlow carbon steel, case hardened and ground. The special jaws are designed to clamp the component as close to the centre to avoid distortion of the component and provide inconsistent gripping.
