Patent number: 7695353Abstract: 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.Type: GrantFiled: November 14, 2005Date of Patent: April 13, 2010Assignees: Toyoda Van Moppes Ltd., JTEKT CorporationInventors: Takayuki Moroto, Kunihiko Unno, Masato Kitajima, Tomoyasu Imai, Yasuhisa Sekiya, Tomohiro Inagaki, Noboru Hiraiwa, Hiroshi Takehara, Toshiaki Sakurai, Shinji Soma
