    摘要: A grinding wheel comprising abrasive grains, a bonding material for bonding the abrasive grains, and grain clusters of accumulated filler grains having a size smaller than the abrasive grains. The grinding wheel may be a vitrified grinding wheel, and in this case, chromium oxide having good affinity with the vitrified bonding material may be used as the filler grains.

    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.

    摘要: In a grinding wheel for use in a grinding machine, a plurality of grinding tips (14) are bonded on the outer peripheral surface (13) of a wheel (10) core having a disk-like shape by bond. On both side surfaces (11) of the wheel core (10) are formed with depressions (12) continuous with the outer peripheral surface (13) of the wheel core (10). Bond is filled between the outer peripheral surface (13) and the grinding tips (14), and filled in the depressions (12) of the wheel core (10) to form a bonding layer (15). Namely, the bonding layer (15) has side portions (15b) which extends along both side surfaces (11) of the wheel core (10) in a radial direction.

    摘要: A solid fats and oils is impregnated in an air space of a stone matrix, as lubrication particles, of a grinding stone. The fats and oils is melted out of the air space to a peripheral surface of the grinding stone to lubricate friction between the grinding stone and a workpiece and to create a space again in the air space of the stone matrix. The created space can perform to receive a cutting tip and to discharge it. The melted lubrication particles lubricate friction between the grinding stone and the workpiece to restrain a generation of heat in order to reduce a grinding resistance. As a result, it restrains a loss of grinding particles on the peripheral surface of the grinding stone to keep a high quality of the grinding characteristics of the workpiece and to extend a truing interval and a life of the grinding stone.

    摘要: A grinding machine rotatably carrying a finish grinding wheel (34) and a super-finish grinding wheel (35) respectively on first and second wheel heads (27,28) practices a method of grinding workpiece surfaces to super-finish surfaces with micro oil pockets. A surface of a workpiece rotatably carried on the machine is first ground with the finish grinding wheel to a predetermined diameter under the control of a sizing device (49,50). The workpiece surface is then ground with the super-finish grinding wheel to a target diameter under the control of a sizing device. The super-finish grinding is performed to the extent that peaks of a section curve representing the roughness of the workpiece surface attained by the finish grinding are removed but bottoms of the surface curve are left to a depth when the target diameter is reached, so that the bottoms so left of the roughness constitute the micro oil pockets.

    摘要: A rotary diamond tool (1) for truing a grinding wheel, comprising one or two circular vapor-deposited base plates (13) each having a thin diamond layer (12) formed by a vapor deposition process such as electron assisted chemical vapor deposition or direct current plasma chemical vapor deposition. The diamond truing tool is further provided with a pair of backup plates (14) brazed on both side surfaces of the one or two circular vapor-deposited base plates so that the stiffness of the diamond truing tool is increased.
