A method for clamping a crankshaft or camshaft in a machine tool chuck has hydraulic clamping of the workpiece in a clamp ring with supporting pressure on the chuck wedges and a centre cone

摘要

The workpiece (50) flange (51) is held by wedges (14,15) and clamped by a clamp ring (21) which is supported by hydraulically powered wedges (22). The chuck (2) slides axially in a body (4) rotated by the machine and has an extension (5) in which a shaft (12) slides to engage a cone (11) in a centre bore of the workpiece.
