PURPOSE:To increase efficiency of the work, by processing a work as pushing the end part of both faces of this work against multi-lined grooves formed in a grinding wheel of a grinding/shaping device, in grinding/shaping saw-edged teeth which is suitable to cut a plywood. CONSTITUTION:In grinding/shaping saw-edged teeth, multi-lined grooves of needed shape are formed on the outer circumferential surface of a grinding wheel 40 which is rotated at low speed. Teeth of one face of a work 50a is grinded/shaped through switching the rotating speed of said grinding wheel 40 to a high speed, and pushing the end part of one face of the work 50a set at the preset position of a work holding unit 50, against the outer circumferential surface of this grinding wheel 40, at a needed cutting edge angle, a needed cutting speed and with the needed cutting depth. Next, teeth of the back face of the work 50a is grinded/shaped through turning over the work 50a, setting this work 50a in the work holding unit 50 after moving the work the preset distance to the preset direction from the former position, and pushing the end part of the back face of the work 50a against the outer circumferential surface of the grinding wheel 40, at the same cutting edge angle, the same cutting speed and with the same cutting depth as the cutting conditions of the former process. |
