ABSTRACT:
A toolholder guide for punch blocks and turrets and the like comprising a toolholder bore carrying about its circumference longitudinal protruding wear strips preventing contact between the toolholder body and the wall of the bore. The wear strips are preferably of plastic and are secured into dovetailed longitudinal keyways broached into the wall of the bore. The innermost surfaces are broached to the a close clearing radius with the body of the toolholder so that the toolholder is accurately centered and guided for reciprocal motion within the bore. Preferably, the broaching operations are carried out using a broaching fixture which secures an actuating hydraulic cylinder directly to the punch block or turret using adjacent toolholder bores for attachment purposes.
