Abstract

PURPOSE: To facilitate attaching and detaching of a work by a method wherein clamping claws sliding along radial grooves of the chuck main body are enabled to obtain large opening and closing strokes.
CONSTITUTION: Both of left and right clamping claws 8 are advanced straight to clamp a journal section J on a supporting table 4, further, they are slided with large strocks by actions of racks 9 and pinions 24 while the journal section is clamped firmly by wedge actions of wedge grooves 10 and wedge sections 36 at tip ends of the claws. After the jounral section J is clamped by the clamping claws 8, a crank pin P of a crank shaft W is cut. When the cutting has been finished, clamping is released in a reversed sequence to the same as described above.
