生させる問題があった。<Problems to be Solved by the Invention> In such a grinding wheel, since the adhesive 3 that connects the grinding wheel pieces 2 does not perform grinding, a large grinding resistance acts on the grinding wheel pieces 2 near the adhesive 3. , the grindstone piece 2 near the adhesive becomes rough. Furthermore, since the surfaces 4 of the grinding wheel pieces 2 that are joined to each other are parallel to the radial direction of the grinding wheel, the roughness 6 progresses as the grinding wheel is used, and in the worst case, there is a problem in that chattering occurs on the outer surface of the workpiece. .

ない。Effect> When the grinding wheel is rotated to grind a workpiece, roughness occurs near the adhesive on the grinding wheel piece. When the outer diameter of the grinding wheel decreases as the grinding wheel is used, the position of the adhesive on the outside shifts in the circumferential direction of the grinding wheel, so that the roughening does not progress.

１は、側面から見て傾斜した面に形成されている。<Example> Hereinafter, an example of the present invention will be described based on FIGS. 1 and 2. Reference numeral 10 denotes a disk-shaped core, and the material thereof is, for example, steel, special cast iron, ceramic, or the like. 20 is a grindstone piece formed by bonding CBN abrasive grains or diamond abrasive grains with resinoid bond or vitrified bond, and the shape when viewed from above or below is rectangular, and the shape when viewed from the side is approximately parallelogram. It is shaped to be. Joint surfaces 2 of the grindstone pieces 20 that join each other
1 is formed on an inclined surface when viewed from the side.
コア１０の外周には砥石片２０が一列に並んでおり、接
合面２１が互いに平行に向い合っている。Grindstone pieces 20 are lined up in a row around the outer periphery of the core 10, and their joint surfaces 21 face each other in parallel.

砥石車４０の外周によりワークの研削加工がなされる。Next, the operation will be explained based on the above-described configuration. Rotating the grinding wheel 40 with the grinding wheel piece 20 fixed to the core 10,
The workpiece is ground by the outer periphery of the grinding wheel 40.

0 occurs. The outer diameter of the grinding wheel 40 is reduced each time it is subjected to grinding or truing, as shown by the two-dot chain line in FIG. The roughness 50 due to deviation in the circumferential direction
does not proceed.

が発生しない利点が得られる。<Effects of the Invention> As described above, the present invention forms bonding surfaces that are inclined with respect to the radial direction of the grinding wheel on the surfaces of the grinding wheel pieces that face each other,
Since the grinding wheel pieces are lined up around the outer circumference of the core and fixed with adhesive, and the joint surfaces are bonded to each other with adhesive, the position of the adhesive on the outside changes as the outer diameter of the grinding wheel decreases. Displaced in the circumferential direction. As a result, there is an advantage that the grindstone pieces near the adhesive do not become rough, and chatter does not occur on the outer surface of the workpiece.
