Abstract
A method of manufacturing a grinding wheel includes a surface unevenness forming step of applying ultrasonic vibrations from an ultrasonic vibration applying unit through water to an annular slot defined in a surface of an annular base along circumferential directions thereof, thereby forming surface unevennesses on either one or both of a side surface and a bottom surface of the annular slot, and, after the surface unevenness forming step, a grindstone fixing step of fixing a plurality of grindstones to the annular slot with an adhesive.
Claims6
A grinding wheel comprising:
- an annular base having an annular slot defined in a surface thereof along circumferential directions thereof;
- and
- a plurality of grindstones fixed to the annular slot by an adhesive, wherein
- the annular slot is defined by side surfaces having first surface unevennesses that are periodic in thicknesswise directions perpendicular to the circumferential directions,
- the annular slot is defined by a bottom surface having second surface unevennesses that are periodic in radial directions perpendicular to the circumferential directions and the thicknesswise directions, and
- wherein at least one of the first surface unevennesses of the side surfaces and the second surface unevennesses of the bottom surface of the annular slot include third surface unevennesses, the third surface unevennesses having a depth smaller than that of the first surface unevennesses and the second surface unevennesses.
