Abstract

An index-feed machining system comprising a plurality of machining units, each having a cassettes having a plurality of machining means and detachably fitted to a machining unit proper, disposed at intervals of mP (m being a given positive integer, and P being a feeding pitch of a workpiece) in a direction in which the workpiece is fed to sequentially machining the workpiece that is index-fed at the feeding pitch of mP, in which a ram is vertically movably provided on an upper end of the machining unit proper constituting the machining unit, a hydraulic cylinder is provided in the machining unit or the ram, a piston is vertically movably provided in the hydraulic cylinder, an actuating unit comprising an eccentrically rotating shaft and the piston that can be engaged with each other via a connecting rod or via a connecting rod and the ram, is provided above the machining unit, and a hydraulic circuit is provided so that operating fluid can be selectively introduced from the hydraulic circuit to an upper part or lower part of the piston so as to cause the ram and the machining means to be engaged or disengaged with each other.
