ッサがそれぞれ用いられている。2. Description of the Related Art A grinding wheel whose meshing performance has been deteriorated by grinding and whose grinding performance has deteriorated recovers and improves sharpness again by dressing. In dressing, the abrasive grains and the bond material are crushed by a dresser, worn, or dropped. As a result, the crushed abrasive grains form new sharp cutting edges, and the bond material on the surface layer of the grinding wheel is removed to form new chip pockets. Conventionally, a porous material obtained by sintering hard abrasive grains has been used as a dresser material. For example, a GC dresser is used in the case of SiC abrasive grains, and a WA dresser is used in the case of alumina abrasive grains.

いる。A diamond or CBN grinding wheel is used for grinding difficult-to-cut materials such as cemented carbide, ceramics and semiconductors. In the grinding wheel, a grindstone made of diamond abrasive grains or CBN abrasive grains is formed on the peripheral surface or the end surface of the wheel body (base metal).

ない。The dresser made of a porous material obtained by sintering the above hard abrasive grains can recover the sharpness of the grinding wheel, but the abrasion of the grinding wheel is large. Therefore, it is not suitable for a grinding wheel using expensive abrasive grains such as diamond or CBN.

きない。Further, in a cleaner in which glass particles are hardened with a resin, cleaning does not unnecessarily crush the abrasive grains.
The abrasion of the grinding wheel due to cleaning is small. However, when the grinding wheel using the bond material having a strong abrasive grain holding force is in a blinded state, it cannot be sharpened.

している。The average particle diameter of the ceramic particles and the glass particles is 1 / the abrasive particle diameter of the grinding wheel to be made to act.
About 5 to 5 times is appropriate. Further, an epoxy resin, a phenol resin or the like is used as the resin binder. As the material of the glass particles, glass mainly composed of silicate is used, and particularly, one for glass fiber (for example, aluminoborosilicate) is suitable. The weight ratio of the inorganic particles is 10
˜70%, the weight ratio of glass particles is about 10 to 70%, and the weight ratio of the bonding material is about 80 to 20%. The dresser may have any shape such as a stick shape, a roller shape, and a cup shape. Note that FIG. 1 schematically shows a stick-shaped dresser 5 which is made by mixing ceramic particles 6 and glass particles 7 and solidifying them with a bond material 8.

Silicon carbide particles with an average particle size of 50 μm, average particle size of 100 μ
The grinding wheel was dressed with a stick-shaped dresser in which m glass particles were mixed and hardened with an epoxy resin. The weight ratio of silicon carbide particles was 25%, the weight ratio of glass particles was 45%, and the weight ratio of epoxy resin was 30%. Further, a grinding wheel under the same conditions as above was dressed with a dresser of GC abrasive grains.

とができる。In the dresser of the present invention, the bonding material of the grinding wheel is appropriately shaved by the ceramic particles to expose the abrasive grains, and the glass particles effectively remove the grinding debris from the surface of the grinding wheel. Therefore, since soft dressing is possible, it is possible to grind with a low load, wear of the grinding wheel is small, and even a grinded grinding wheel can be sharpened. Further, if it is used in-process, even a grinding wheel having a weak self-dressing action can be prevented from being in a blind state.
