Abstract

PURPOSE: To improve the yield of material and to reduce the cost, by clamping only the outer rims that are the position of a material corresponding to the two opposing sides of a valve seat, and by punching the material precisely.
CONSTITUTION: The parts of a material which correspond to the position of two opposing sides of a valve seat are made outer clamping rims 9, and the parts of the material 1 which correspond to the other two sides are made to coincide with the ends of the material 1. Then, a boring process A, a chamferring and grooving process B, a chamferring of the back side surface and its grooving C and a cutting process D are carried out. Therefore the material yield is improved. In this case, as the parts of the material 1 composing the outer clamping rims 9 are cut after cutting off the valve seat by the same blade, a scrap 10 is bar like thus sparing the breaking of the scrap.
