となっている。(Example) Next, the present invention will be explained in more detail with reference to an example of the illustrated shaft-equipped grindstone. (11 is a cylindrical grindstone body formed at the tip of the shaft (2) An abrasive electrodeposition part (3) is formed, for example, in a spiral shape on the outer peripheral surface of the abrasive grain electrodeposition part (3), as shown in an enlarged view in FIG. Super abrasive grains (4) such as or diamond abrasive grains are fixed to the surface of the grinding wheel body (1) by a plating part (5) formed by electrodeposition, and a spiral non-electrodeposited part ( 6) is formed in a concave shape between the abrasive grain electrodeposition parts (3).In the present invention, the bottom surface of the abrasive grain non-electrodeposition part (6) is formed by exposing the grinding wheel body (1) as in the conventional case. It is not a completely non-electrodeposited part, but a thin plating layer (7) is formed as shown in the figure, and this plating layer (
7) has a structure in which the abrasive grain electrodeposition parts (3) and (3) on both sides are connected.

することができる。To manufacture such a grinding wheel, a material such as cotton thread, which allows the electrolyte to penetrate but prevents the adhesion of abrasive grains, is used as a masking material on the surface of the grinding wheel body (1), and this is used as a masking material on the surface of the grinding wheel body (1). Use a method of partially masking the surface of the main body (1) by wrapping it in a spiral shape, immersing it in an electrolytic solution containing superabrasive grains, and performing electrodeposition according to a conventional method. I can do it. In this way, the masking material can prevent the abrasive grains from adhering to the abrasive grain non-electrodeposited areas (
6), and the electrolytic solution soaked into the masking material forms a thin plating layer (7) on the bottom surface of the abrasive non-electrodeposited area (6). Although the embodiments described above relate to a whetstone with a shaft, the form of the grinding wheel is not limited to this, and may be in various forms such as a disc-shaped one, a cup-shaped one, or a grinding stick. I can do it. Further, the shape of the abrasive grain non-electrodeposited portion (6) is not limited to a spiral shape, but may have any irregular shape such as a lattice shape or a checkered pattern.

とができる。(Function) A grinding wheel constructed in this way can be attached to a grinding machine or other grinding tool and used for grinding the inner surface of a hole, grinding the surface of a mold, etc., in the same way as a conventional grinding wheel. Since the grinding surface of the grindstone body (1) is formed in an uneven shape by the abrasive electrodeposited portion (3) and the abrasive non-electrodeposited portion (6), the abrasive grain non-electrodeposited portion (6) is uneven. The workpiece is efficiently ground by the edge portion, and chips are smoothly removed by the abrasive non-electrodeposited portion (6), making it possible to exhibit excellent grinding ability.

3) and (3) are connected, so compared to the conventional one shown in Fig. 3, in which the abrasive grain electrodeposition part (3) was cut off, the abrasive grain electrodeposition part (3) can be removed from a part of the corner. Peeling may occur <<,
There is no risk of abrasive grains peeling off or falling off even after long-term use.

Moreover, it is highly durable and does not easily cause the abrasive grains to peel off or fall off, so it will greatly contribute to the development of industry as a grinding wheel and its manufacturing method that eliminates the problems of conventional grinding wheels.
