TOOLHOLDER

摘要

A toolholder (20) comprises a body portion (32), a support member assembly (33) mounted to the body portion and an insert-receiving cartridge (36) removably received in the support member. The insert-receiving cartridge (36) includes a pocket (38) for mounting a cutting insert (40) thereon. The support member assembly (33) includes a bore and the insert-receiving cartridge (36) includes a shank capable of being received in the bore. The combination of the insert-receiving cartridge (36) and the cutting insert (40) forms a cutting tool for a particular cutting operation. In one embodiment, the cutting tools are radially mounted to a side periphery of the body portion (32) such that the vertical axis of the cutting tool is substantially parallel to a longitudinal axis (L) of the toolholder (20). In another embodiment, the cutting tools are longitudinally mounted to an end surface of the body portion (32) such that the vertical axis of the cutting tool is substantially parallel to the longitudinal axis (L) of the toolholder (20). The cutting tool may be canted to provide clearance for the tools on the reverse side of the toolholder (20). An actuator bolt, in cooperation with an actuator nut, allows the insert-receiving cartridge (36) to be quickly and easily removed from and installed onto the support member assembly (33) to provide a quick change of the cutting tool, or replacement of only the damaged part. In addition, rotation of the toolholder (20) allows for a quick change of a tool machine operation.
