Abstract

A cutting-processing machine comprises a vice mechanism for clamping a workpiece to be cutting-processed, a pair of cutting units 6 for cutting-processing both ends of the workpieces, arranged to face one another with the vice mechanism being interposed between both the cutting units and; back-and-forth shifting means 10 for moving back and forth each of the cutting units 6 relative to processing positions for both the ends of the workpiece, comprising a guide member 12 for controlling the movement of the cutting unit, a ball-combined feed screw type feed mechanism 13 for moving the cutting unit reciprocally along the guide member, and a servomotor 15 for setting a feed screw bar 14 of the feed mechanism in rotational motion, wherein a contact projection 32 is provided on a front side of the cutting unit 6, and a stopper 33 is arranged to retractably jut over a moving passage of the cutting unit so that, when the cutting unit is caused to advance from a backward position, the contact projection 32 comes into contact with the stopper 33, and thereby the cutting unit 6 stops at/near a position where the cutting unit is about to start processing to the workpiece, and such a stop position of the cutting unit is adopted as a reference point of the feed quantity of the cutting unit.
