24が摩耗してこの状態を作り出している。As shown in FIG. 3, the main part of the abrasive layer 2 is a resin 23 having heat resistance or the like, and a filler 23 as a solid lubricant, for example, graphite, molybdenum disulfide, talc or the like. Hard abrasive grains 21 such as diamond abrasive grains and CBN (cubic boron nitride) abrasive grains are dispersed.
Hard abrasive grains 21 protrude from the bond surface 24 formed by the resin 22 and the filler 23 on the surface of the abrasive grain layer 2.
This is the requirement for the grinding action, and the bond surface during use

As shown in the enlarged view of the abrasive layer 2, a solid such as porous silica gel as a lubricant, talc, activated carbon and the like have a large surface area and a good impregnation property, and are slightly harder than the resin that is the main component of the bond. It is characterized by using an oil-containing solid 20 in which a solid contains a lubricating oil such as silicone oil. By doing so, the lubricating oil permeates the ground surface during use to perform a lubricating action and a cooling action. Of course,
The solid lubrication effect of fillers such as molybdenum disulfide and talc is also exerted.

The preferred range of the oil-containing porous silica gel is 3 to 5% by weight.
