摘要： In a wheel spindle device wherein a plurality of grinding wheels are attached in a juxtaposed relation to a wheel spindle rotatably carried on a wheel head of a grinding machine, a reference position for specifying a position in the circumferential direction of the grinding wheel is provided on a core member of each of the grinding wheels, and a plurality of inclined grooves at predetermined angular intervals are formed on a grinding surface of each grinding wheel to be inclined relative to the circumferential direction of each grinding wheel. In order that the fluctuations in the dynamic pressure and the grinding resistance between respective grinding wheels and workpiece portions ground therewith do not grow as a combined or synergy effect, the inclined grooves on each grinding wheel are shifted in angular phase from those on another grinding wheel, so that grinding efficiency and accuracy can be enhanced.

摘要： First and second end surface truing sections are formed by protruding cylindrical first and second base bodies from opposite end surfaces of a disc-like base of an opposite end surface truing tool in the axial direction thereof and by providing on the external surface of the first base body and the internal surface of the second base body first and second abrasive grain layers in which numerous diamond abrasive grains are adhered with bond material. The rotational axis of the opposite end surface truing tool is inclined relative to the rotational axis of the grinding wheel within almost the same plane at a predetermined inclination angle. By moving the opposite end surface truing tool toward the rotational axis of the grinding wheel, the first and second abrasive grain layers respectively true the grinding surfaces at the opposite ends of the grinding wheel under almost the same condition to sharp grinding surfaces having moderate ruggedness, as they go ahead of the first and second base bodies to be backed up thereby. Consequently, it can be realized to true the grinding surfaces at the opposite ends of the grinding wheel under almost the same condition to the sharp grinding surfaces having the moderate ruggedness.

摘要： An abrasive tool includes an electroformed layer having superabrasive grains electroplated on an outer surface of the electroformed layer, and a plurality of dimples arranged on the outer surface of the electroformed layer using a mold with projections made of gel adhesive. The concentration of the abrasive gains is regulated by changing the number of the dimples (i.e., changing a dimple-area-rate). The gel adhesive preferably has a viscosity of 500,000 cP or smaller. The dimple-area-rate is preferably from 7 to 70%.

摘要： A grinding wheel for grinding a workpiece has a first grinding surface and a second grinding surface successive thereto. The first and second grinding surfaces are parallel to and inclined with respect to the rotational axis of the workpiece, respectively. A diameter of the workpiece to be ground in a next grinding operation is measured in advance. An angle to be formed between the second grinding surface and the rotational axis of the workpiece is selected based upon the measured diameter of the workpiece. The selected angle is established between the second grinding surface and the rotational axis of the workpiece. The grinding wheel is moved relative to the workpiece in a direction of the rotational axis of the workpiece, whereby the cylindrical surface of the workpiece is firstly ground by the second grinding surface and subsequently ground by the first grinding surface of the grinding wheel.

摘要： A grinding wheel for use in a grinding machine, wherein a plurality of grinding tips are bonded on the periphery of a wheel core having a disk-like shape using a bond which forms a bonding layer between the wheel core and the grinding tips. The grinding wheel is further provided with means for preventing coolant from entering inside of the abrasive layer and/or bonding layer, thereby preventing the bonding layer from being swelling by the coolant. In a first embodiment, the preventing means is composed of rubber layers formed on the both side surfaces of the grinding wheel at the places corresponding to the radial position of the bonding layer. In another embodiment, the preventing means is composed of water-repellant material capable of repelling water. Such material is composed of silicon or fluorine resin and is soaked into the grinding tips.
