摘要： A grinding method of a rotating workpiece W having a cylindrical part 20 and a pair of end faces 21 at both sides of the cylindrical part 20 uses a grinding wheel 10 whose grinding stone is narrower than a finishing width S1 between the end faces 21. In a first grinding step, the grinding wheel 10 is relatively moved to the cylindrical part 20 in a direction crossing the rotational axis of the workpiece W and is shuttled along the rotational axis of the workpiece W at least one time between the finishing width S1 of the end faces 21 until the grinding wheel 10 reaches the cylindrical part. And in a second grinding step, the grinding wheel 10 is moved from one of the end faces 21 to the opposite end face 21 on the cylindrical part 20, so as to finish the end faces 21 to a predetermined width S1.

摘要： A cutting tip including a cutting edge portion made of a high-hardness material to take a thin-plate shape; and a support portion made of a material which is more worn in contact with a workpiece than the cutting edge portion not to exert a machining action on the workpiece even in contact with the workpiece, and securing and supporting the cutting edge portion on a reverse side of a rake face of the cutting edge portion. Thus, the width of flank wear is prevented from increasing and chipping of the cutting edge is prevented, so that the life of the cutting tip can be extended.

摘要： A crankpin 1 of a crankshaft rotatably supports a big end of a connecting rod 4 through a sliding bearing 5 fitted therein. The sectional profile of the crankpin 1 takes the form of a polygon whose profile is made of plural arcs of curvature. When the crankpin 1 rotates relative to the bearing 5, the wedge effect is generated to decrease the squeeze loss, a kind of the power loss. And, the oil film thickness between the crankpin 1 and the bearing 5 is secured to prevent the shear loss, another kind of the power loss, from increasing, whereby the power loss can be decreased in total.
