Abstract (en)

[origin: EP0321972A2] A grinding wheel (10) is provided with a rotating machining surface (30, 31) made of an abrasive material and is provided with a central location opening with a metallic location surface. In order to increase the mechanical stability of the grinding wheel and thus to make possible in particular external cylindrical grinding with an extremely high rate of metal removal, the grinding wheel (10) is designed as a metal wheel (16) and is provided at its periphery with a narrow border (13) of abrasive material. <IMAGE>
