ABSTRACT:
Disclosed is a machine for grinding edge areas of slab formed parts including a pair of grinding units pivotally supported on opposite sides of a part clamped for rotation. Pressure elements carried by the frame press the grinding belts against the formed part. Means are provided for adjusting the direction of approach of each grinding belt in accordance with the rotational position of the part so that the angles formed by the belt and the formed part as the belt approaches and leaves the formed part are generally equal to one another.
