Abstract

PURPOSE:To improve the surface roughness of a cutting edge part, make adhesion of TiC, TiN secure, and improve life by cutting and heat treating serration grooves and, then, after grinding said grooves, coating TiC, TiN on the side faces of the grooves. CONSTITUTION:A material for a shaving cutter is turned to form serration grooves with margins for grinding and, then, it is heat treated to obtain a certain hardness. After that, a form grinding wheel 1 is rotated to grind the margin for grinding, forming a shaving cutter 5 having serration grooves with defined dimensions and a define configuration. Then the cutter 5 is subjected to surface coating of TiC or TiN on its whole surface. And, since the surface roughness as the ground for coating of the cutter 5 is improved by means of the grinding wheel 1, good adhesion of TiC, TiN can be obtained, thereby improving the life of cutter, enabling the regrinding of the serration-groove bottom surface by neans of a specially designed manufacturing tool, and increasing the number of regrindings to be available.

ものとなる。In this case, the shaving cutter 5 is finally formed by the general shape grinding wheel 1. In this case, the M1 surface 2a of the general shape grinding wheel 1, which forms the cutting edge portion 2, is also formed. The shaft portion 1a (see FIG. 1) connecting the end surface 2b and the cutting edge portion 2 has a serration groove 7OflllJ surface 7a, respectively.
Similarly, it engages with the bottom surface 7b of the serration groove 7 and the tooth surface 6a of the tooth s6 (see FIG. 2) to perform the finishing process.

以下、上記総形研削砥石ｌを用いたシェービングカッタ

1 Execute coding. This coating is usually performed on the entire surface of the shaving cutter 5 by vapor deposition, and the coating is applied to the entire surface of the shaving cutter 5 by several tens of microns.
It is assumed that the shaving cutter 5 is formed at a J speed of In addition, the coating may be applied only to the field surface 7aVC of the serration groove 7, which is formed by the cutting edge, and in this case (Good 1) 1i pond is 1j
A resist is applied to the area except for surface 7a, and after vapor deposition, the resist is washed and removed.
