うこと（Ｊ、きわめて大きな１］ス（゛あった。。This type of rotating f tool has an annular part on the outer periphery that is used as a cutting edge, so it has conventionally been made into an integrally molded piece of cemented carbide, as shown in Fig. 1 by 1. The solid type was returned. For this reason, the outer circumference side portion 1a used as a cutting edge is worn out, and the waste diameter A, which is set in advance at the usage limit, is reduced.

んど−イ本物として取扱えるようになされ（いる。The present invention will be explained below based on an embodiment shown in FIG. This rotational application]2]2 is a shift (not shown).
It is an annular member that is fitted into the ring and driven to rotate around the center l1llllp, and is formed as a combined body of the cutting edge ring 2 on the outer circumferential side and the base metal ring 3 on the inner circumferential side. Both rings 2 and 3 are molded products made of cemented carbide,
The inner diameter of the cutting ring 2 on the outer circumferential side is slightly reduced to a predetermined waste diameter Cd3, and a base metal ring 3 is fitted onto the inner circumference of the cutting ring 2. Note that the base metal ring 2 is formed to be narrower than the cutting blade ring 2 for convenience when finishing the side surface of the cutting blade ring 3, and is fitted with a gap a on both sides. has been done. The fitting part is firmly bonded with brazing adhesive, so that it can be handled as if it were a real product.

がれやクラックが防止されることにイｆる。The reason why the cutting edge ring 2 and the base metal ring 3 are both made of Ki cemented carbide is to make their coefficients of thermal expansion the same and to avoid the problem of thermal effects on the fitting parts. It's for a reason. By doing this, for example, the residual stress in the soldered portion is reduced, and peeling and cracking in that portion is prevented.

Uncouple the base metal ring 3, discard only the cutting blade ring 2, and replace it with a new one. In this case, the existing base metal ring 3 is reused, and a new cutting ring 2 is fitted and connected to it to form a re-marking rotary machining tool.

1. If wear progresses, replace only the outer cutting edge ring.
The base metal ring is designed to be reused as much as possible, so that the waste rate can be kept small, and the monthly charge for the cemented carbide base metal ring is not as expensive as that of the conventional solid type. In addition, according to the present invention, the base metal ring as well as the cutting edge ring are made of cemented carbide, so the fitting part (42 pairs) It is possible to prevent problems caused by heat effects, and is particularly effective in brazing (=I) joints.
