[Problems to be Solved by the Invention] In the above-mentioned dressing device equipped with a dressing tool using a conventional point diamond, there is a problem that the point diamond wears out quickly. Since it cannot be used to form a grinding wheel, it has been necessary to use a dressing device equipped with a rotary dressing tool using, for example, a rotary diamond.

However, in a conventional dressing device equipped with a rotating dressing tool, the pulleys and belt portion of the belt transmission device that transmits rotation from the motor to the dressing tool may interfere with the grinding wheel or the grinding wheel flange, or the rotating portion of the dressing device may Because the turning radius becomes large and the dressing device itself becomes large, it is difficult to install it on the grinding machine. Conventionally, it is difficult to install a dressing device that can form a CBN grindstone into a convex curvature shape on the same grinding machine. The grinding machine provided did not exist.

[0007] Therefore, it was necessary to once remove the CBN grindstone from the grinding machine and shape it using a separately provided dressing device. In this case, it takes a lot of effort to reinstall it on the grinding machine, and it is difficult to restore the same accuracy as before removal. It could not be used for grinding work.

[Operation] By numerically controlling the movement of the rotating body holder and the rotation of the rotating body, the outer peripheral surface of the rotary dressing tool can be moved in a circular motion with an arbitrary radius of curvature, so the grinding wheel can be shaped into any curved shape.

[0011] Since a dressing tool that is rotationally driven to shape the grinding wheel is used, even a grindstone made of ultra-hard abrasive grains such as a CBN grindstone can be formed. Furthermore, compared to point diamond dressing tools, there is less wear and the grindstone can be formed in a shorter time.

[0012] Since the rotation of the rotary drive shaft is transmitted to the tool shaft of the rotary dressing tool through the screw gear, there is no need for a belt transmission device, and furthermore, since the rotary drive shaft is passed through the revolving body in parallel, , the turning radius of the turning portion of the dressing device can be reduced. Therefore, the device can be downsized and can be installed on a grinding machine.
