Progressive processing device

An index-feed processing system comprising a plurality of processing units, in which cassettes having processing means are detachably provided in the unit body thereof, disposed at intervals of mP (m being a given positive integer, and P a feed pitch of workpiece) in the longitudinal direction of a long-sized workpiece corresponding to a plurality of processing processes, so that the processing processes are performed sequentially as the workpiece is indexed at the aforementioned pitch;

• the improvement being such that the unit body comprises a base plate, a support plate provided at a predetermined distance from the base plate, a slider movably provided between the base plate and the support plate in the direction orthogonally intersecting with the base plate and the support plate, and a drive means for driving the slider;
• and
• a given processing unit functions as a machining unit, and other processing units as various processing processes including press working units, so that various processing operations, including machining and press working operations, can be performed in succession by controlling the movement of the slider.
