Abstract
The tailstock of a universal grinding machine has a lower part which is affixed to the frame at a level below the indexible head for a set of grinding spindles, and an upper part which supports one or more dead centers and is indexible relative to the lower part about a horizontal axis extending at right angles to the axis or axes of the center or centers. The upper part of the tailstock has several facets and the number of such facets exceeds the number of dead centers by at least one. Each center is mounted on a discrete facet and the unoccupied facet is indexed to a position below the material removing station of the grinding machine when the head is to be indexed whereby the center or centers on the upper part of the tailstock cannot interfere with movements of the selected grinding wheel to and from the material removing station. The head can support a grinding wheel for removal of material from cylindrical external surfaces of workpieces, a grinding wheel for removal of material from cylindrical internal surfaces of workpieces, and a grinding wheel for removal of material from flat surfaces.
