Description

These chucks are meant for mounting on conventional and special lathes.
Chuck design secures high-pressure force transfer with much less vise grip wrench torque in comparison with concentric jaw chucks. Wedge-strip chucks have high wear resistance and long lifetime, stability in reaching of high centering accuracy of workpieces. Chucks are made on a basis of a hardened steel case, and include hardened jaws set.
Under the customer request chucks are packaged with additional set of soft jaws and intermediate jaws for specific setups with them. Hardened chucks function as direct  and reverse jaws when realignment.
