    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.

    摘要： A dressing apparatus for dressing an electroplated grinding wheel by crushing the top portions of the abrasive grains thereof. The abrasive grains are diamond grains or CBN grains. A role made of ceramics, or a ferrous role holding diamond grains on its outer periphery is used for crushing the abrasive grains. The grinding wheel is rotated in one direction and the role is rotated in the opposite direction so that the difference in surface speed between the role and the grinding wheel becomes substantially zero. The role is then advanced toward the grinding wheel to crush the top portions of the abrasive grains, so that the heights of the abrasive grains are roughly equalized, and many sharp cutting edges are formed at the top portions of the abrasive grains.

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

    摘要： A metal part in which a base material of silicon-aluminum alloy having 1 to 25% by mass of silicon as an anode is immersed in an electrolyte together with a cathode, and at least a portion of a surface of the base material is anodized and coated with an anodic oxide film. A current density provided to both the anode and the cathode is increased from an initial current density of 0 A/dm2 at a rate between 0.15 and 0.35 A/dm2 per minute, wherein once the current density reaches a prescribed current density of between 0.8 A/dm2 and 1.2 A/dm2, the current density provided to the anode and the cathode is maintained at the prescribed current density.
