ABSTRACT:
A process a plate workpiece with high precision at high speed, the plate processing machine comprises a workpiece side surface positioning device (SPD) provided with magnet rollers (MR); a workpiece trimming device (TD) provided with a tool actuating switch (SW); and a workpiece positioning device (PD) provided with an optical sensor (SE). The magnet rollers guide a workpiece forward in magnetic rotatable contact engagement with the side surface of the workpiece. The tool actuating switch is actuated before the workpiece is located at a trimming position for automatic trimming operation. The optical sensor generates a feed speed deceleration signal so that a fed workpiece will not apply shock to the stop member of the positioning device by adjusting the sensor position relative to the stop surface according to the workpiece length to be cut.
