Abstract
Abstract An elongated arm having a grinding wheel turnably mounted at its front end is supported by a cylindrical bearing to rotate about an axis of the arm. The bearing is pivotally received upon a work head which is reciprocal for a predetermined length on a carriage. At the lower fore portion of the bearing, there is provided adjusting means to adjust the angle of elevation of the arm. The adjusting means runs along the upper surface of a copying surface plate, the surface plate also being adjustable in its angle of elevation.
