Description of the Related Art As a grater for cooking made of metal, a thin metal plate is punched in a star shape, and a circular hole is formed, and a triangular projecting plate is formed at the edge of the circular hole. It is known that a formed metal plate or a thick metal plate having a chisel-shaped surface is used to form a protrusion for cutting. However, the former is low in cutting ability and inferior in durability, and the latter is high in cutting ability and excellent in durability, but there is a drawback that the fibers of the food are caught on the protrusion during its use. In addition, in the production thereof, the step of raising the projection must be repeated several times, which is very complicated.

As shown in FIG. 2, the grater is formed by forming a large number of through holes 2 in a body 1 made of a thick metal plate and forming a cutting blade 3 by projecting the hole edge of the through holes 2. The manufacturing means uses a known fine blanking method. That is, a press working apparatus capable of performing a fine blanking method when punching the through holes 2, specifically, a plate holder 5 is arranged around the punch 4 as shown in FIG. Correspondingly, the reverse press 7 is arranged. In this press machine, the plate holder 5
Punch 4 to completely press the work piece with
The protrusions 51 are provided on the peripheral portion of the protrusion 5.
1 is provided, and a concave portion 61 having a shape corresponding to the cutting blade 3 is also provided on the upper surface of the die 6.

研削板（おろし金）を製出できるものである。As shown in FIGS. 3, 4 and 5, when the through hole 2 is to be punched and formed in the grater body 1 by this press working apparatus, the plate holder 5 is lowered to strongly press the body 1. To form a protruding portion to be the cutting blade 3 and simultaneously lower the punch 4 to punch the through hole 2.
The through hole 2 and the cutting blade 3 are simultaneously formed by a single punching process. In addition, the punching process is performed by strongly pressing around the punch 4.
Since the clearance of the die 6 is made as small as possible, the cutting blade 3 formed by projecting and forming a punching cut surface as a shearing surface has a sufficient grinding ability. Therefore, a desired grinding plate (grater) can be produced by punching out the necessary number of through holes 2.
