摘要： An ELID centerless grinding apparatus comprising: a blade 2 for horizontally supporting a rotator workpiece 1 and and a regulating wheel 10 driven to rotate around a horizontal shaft center. An outer surface of the workpiece is subjected to ELID grinding by using a conductive grinding wheel 4. An outer peripheral portion of the wheel 10 includes a conductive elastic member 11 and abrasion resisting particles 12. An electrolytic electrode 14 is provided in close vicinity to an outer peripheral surface of the wheel 10. An electrolytic power supply 16 applies an electrolytic voltage between the electrolytic electrode and the wheel. A conductive electrolytic fluid is flow between the electrode and the wheel and the member 11 is removed by the electrolytic dressing to cause the abrasion resisting particles 12 to project, while the particles 12 are brought into contact with the outer peripheral surface of the workpiece 1 to rotate around its shaft center. Consequently, the coefficient of friction of the outer peripheral surface shape of the regulating wheel 3 with respect to the workpiece can be maintained more or less constant during the grinding process of the workpiece.

摘要： The method disclosed here comprises the steps of (a) mixing metal powder, a resin, abrasive grains, and a solid reducing agent at the normal (room) temperature through the melting point of the reducing agent to form a mixture and (b) molding and baking the mixture at the melting point of the reducing agent through that of the metal powder. The solid reducing agent is a fatty acid, preferably stearic acid having a volume ratio of 5 to 20% with respect to the metal powder. With is, it is possible to make metal-resin bond grindstones that give such high-quality mirror surfaces that have conductivity fit for ELID grinding and are not liable to have chippings or scratches and also have an Rmax value of approximately 3 nm or less.
