Gmt Manual Chuck - High Tensile Alloy Steel, Quick Jaw Change Mechanism, Enhanced Gripping Power And Concentricity For Small To Medium Batch Production

The production capacity of a lathe is entirely a function of the chuck used, the gripping power and the true running of the chuck. A lathe with the excellently engineered GMT chuck enhances the productive capacity of the lathe which provides the answer to faster and better guaranteed production. Manual Chucks with Quick Jaw Change meets the growing needs of the present day small to medium batch production. It provides high reliability and concentricity and the Quick Jaw Change facilitates quick and accurate Repositioning Reversing or Jaw changing operations quickly and accurately.The conventional bevel gear and scroll have been replaced by a worm & worm wheel to operate the jaws. The worm & worm wheel and the circular cam gives the chuck an amazingly high mechanical advantage and gripping power .The chuck body & the worm wheel cum cam ring are made from steel forgings,which provide the desired grain flow & thus minimise distortion under the clamping forces.All the parts are amply proportioned made from high tensile alloy steels,hardened & grounded wherever necessary to close limits of accuracy.The hard jaws are provided with gripping serrations to grip the work piece firmly.The normal dimensional variation in the gripping diameter of jobs is taken care of by the adequate stroke of the base jaws,thus avoiding frequent resetting of the false jaws.soft jaws are made from low carbon steel & used for second operation .
