ABSTRACT:
A grinding wheel is disclosed with a disk-like, cylindrical shape, whose perimeter is equipped with a grinding abrasive and has at least one spiral groove. The groove extends essentially around the perimeter at an acute bevel angle of inclination less than 45.degree. to a radius line normal to the axis of wheel rotation. Preferably the bevel angle is designed as an acute angle and is sized so that the groove extends over at least one full circumference of the grinding wheel. The face of the ribs may be tapered and the corners chamfered. Multiple parallel or non-parallel grooves may be employed. Improved cutting, service life and surface characteristics of the processed workpiece are obtained.
