Two-jaw power chucks
Are meant for clampingworkpieces, machined on lathes of accuracy class N and P, in serial and mass production conditions.
Chuck works from motorized drive, mounted on a back spindle terminus of a machine.
Adjustment on a required clamping diameter is performed by remounting of jaw hardened inserts by main jaws riffling, thereby required chuck accuracy remains.Accuracy of the chuck with unhardened jaws is reached by boring of jaw inserts after remounting of them on a required diameter.
