摘要： A grind-machining method of ceramic materials characterized in that a peripheral speed of a grinding wheel relative to a working surface is set to 50 to 300 m/sec, a feed stroke speed of the working surface of the grinding wheel in a working direction is set to 50 to 200 m/min, and preferably, a down-feed speed of the working surface of the grinding wheel in a direction orthogonal to the surface of the workpiece is set to 0.05 to 3 mm/min. The grind-machining method of ceramic materials can reduce a grinding force at the time of grinding of ceramic materials and residual defects due to machining, and at the same time, can accomplish high machining efficiency.

摘要： A mixed powder is obtained by adding at least one kind of solid ester wax to an iron-based powder for powder metallurgy use. The mixed powder is molded. The melting point of the ester wax is 100° C. or lower, the quantity of the ester wax added is in the range of 0.02 wt % or more to 0.6 wt % or less, and the temperature of the mold when the molding is performed is set in a range of (the melting point of the ester wax+10° C.) or more to 200° C. or less. The ester wax thereby liquefies on the surface of the mold and bleeds out when the molding is performed. As a result, molded sintered parts with complex shapes, good surface characteristics, and high densities can be easily obtained.

摘要： First and second sliding parts of a sliding mechanism slide relative to each other. The first sliding part is held in a recess of a metal holding member, which is bounded by an inner wall that meets an open end of the recess along an edge. The first sliding part has a first side surface portion that contacts the inner wall in the recess away from the edge, and a second side surface portion displaced inwardly away from the inner wall so as not to contact the holding member at the edge. By this structure, generation of stress concentration on the sliding part can be avoided.
