<p>The abrasive wheel (1) has flexible abrasives arranged on the abrasive wheel, where the concentration of the abrasive is high within an imaginary abrasion triangle and is low within an imaginary triangle-shaped abrasion shadow. The hypotenuse of imaginary abrasion triangle is designed concave and the adjacent sides of the abrasion triangle are designed convex.</p> |
