The apparatus for the performance of the aforesaid method contemplates the provision of a number of grinding bodies which are rotatably mounted about their axis at a circle at a grinding wheel or head, and wherein the grinding wheel is rotatable about an axis containing the center of the aforesaid circle. Drive means serve for the rotation of the grinding bodies.
