摘要： A grinding tool has diamond superabrasive grains as the abrasive and a bond to retain the abrasive grains. The bond is made of organic polymer or metal and contains as a filler both a solid film-forming lubricant and finely divided diamond superabrasive grains having a grain size smaller than one-third that of the diamond superabrasive grains as the abrasive. The grinding tool of this invention is suitable for grinding a hard cutting material such as cutting tools made of titanium nitride cermet and exhibits outstanding cutting performance and durability.

摘要： In a vitrified bonded grinding wheel having superabrasive grains 11 such as CBN, diamond or the like bonded with a vitrified bond 12, pores 16 of the vitrified bonded grinding wheel has impregnated thereinto a resin 17 consisting of any resin selected from, e.g., unsaturated polyester, vinyl ester and allyl ester which are in a liquid state at the normal temperature and which have a thermosetting property, and being capable of radical polymerization. Thus, any separation gas or the like is not generated when the impregnated resin is hardened, whereby the strength of the grinding wheel can be enhanced.

摘要： A CBN grinding wheel having a circular core and an abrasive layer formed on the peripheral surface of the core. The abrasive layer comprises high toughness CBN grains and medium toughness CBN grains, wherein the high toughness CBN grains are incorporated into the abrasive layer in a ratio of 10-80% by weight with respect to the total amount of the CBN grains.

摘要： In a grinding wheel in which abrasive tips for rough grinding and abrasive tips for finish grinding are alternately bonded to a periphery of a disk type base rotating about a rotation axis, each abrasive tip includes the abrasive layer formed by bonding abrasive grains and a lower layer overlaid and integrally for led with the abrasive layer. The abrasive tip is attached to the periphery of the base at the lower layer. A Young's modulus of the lower layer of the abrasive tip for finish grinding relative to a load acting on the grinding surface of the abrasive tip in an inward direction of the grinding wheel is less than that of the abrasive tip for rough grinding. Thereby, the surface of a workpiece can be both rough-ground and finish-ground with superhigh-precision surface roughness with using one grinding wheel.
