PROBLEM TO BE SOLVED: To provide a punch for a press work, which punch can reduce a cost and a machining time in a renewal manufacturing process, and also can reduce a cost in a maintenance work. SOLUTION: The punch for the press work is composed of a plurality of members and is divided into a punch tip 1 and a punch body 2. When the punch becames unusable because of the wear or fracture due to the press work, it is enough to remake the cutting edge portion only. By this reason, the cost and machining time in the renewal manufacturing process and the maintenance cost can be reduced. COPYRIGHT: (C)2006,JPO&NCIPI
