ABSTRACT:
In an inside grindstone and a washing method thereof, a plurality of concave cut-outs are arranged on both sides of a cutting-edge layer which is formed at an inner periphery of an annular substrate. Parts of abrasive grains at both sides of an outer periphery of the cutting-edge layer are smaller in projecting amount than parts of the abrasive grains on an inner periphery of the cutting-edge layer.
The washing method comprises the step of blowing off shavings accumulated in the concave cut-outs, by abrasive liquid and jetting gas which are jetted toward the cutting-edge layer.
