本発明は使用前後の刃先の識別が容易なセラミックスロ
ーアウェイチップに関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a ceramic indexable tip whose cutting edge can be easily identified before and after use.

欠点であるが、現在のところ何らの対策もたてられてい
ない。One of the difficulties in using tool materials such as the AA203-Tie series mentioned above is that when used for micro-cutting, the service life is reached with little wear, but in a workplace with low illumination, it is difficult to distinguish between the used cutting edge and the used cutting edge. One example is that it is difficult to understand. This is a particularly noticeable drawback when the ceramic material is black, but no countermeasures have been taken at present.

知見を得、これに基いて本発明に到達したものでるる。As a result of repeated research in order to eliminate the above-mentioned drawbacks of ceramic cutting tool materials, the inventors of the present invention found that when using a ceramic indexable tip whose surface is coated with a metal film, the coating layer is removed by cutting, especially at the cutting edge. The present invention was based on the knowledge that it is easy to distinguish between the metal-colored front cutting edge and the worn-out ceramic-colored, black or other ceramic-colored cutting edge after use.

に用いるなどの方法が採られる。It is preferable to coat one or more metals such as W or alloys thereof, such as Ni-C'r alloy, Ti-At alloy, Fe-Or gold alloy, with a thickness of 02 μl or more and 20 μm or less. If the thickness is less than 0.2 .mu.m, a change in color tone is observed, and if the thickness is less than 20 .mu.rn, the side abrasion of the cutting edge deteriorates, so it is not preferable. When using two or more types of metals in the present invention, for example, a method may be adopted in which a metal with strong adhesion to the base material is used in the first layer, and a metal with a beautiful color such as gold is used in the second layer. It will be done.

回部である。As a method for coating metal films, physical vapor deposition is superior in terms of uniformity of the film, but electroplating is also suitable for conductive materials.

とが使用上、有利である。In the present invention, the coating layer made of metal or alloy must cover at least the cutting edge portion of the indexable tip, and desirably, it is advantageous for use to cover the entire surface of the tip.

However, with uncoated indexable inserts, the cutting edge after use and the cutting edge before use could be distinguished and became loose.
