ABSTRACT:
A vertically arranged circular or polygonal grinding tank and shafts which are fixed to or rotatably formed on a main shaft plate provided rotatably above the grinding tank are provided. The grinding tank is charged with such proper grinding material as hone grains or a medium and workpieces are held or suspended from the shafts and are submerged and moved into the grinding material. The main shaft plate is rotated, and the shafts are stopped, rotated or moved through different angles. Either or both of the grinding tank and main shaft plate is or are moved up and down so that the workpieces may be ground by the frictional slide and flow of the grinding material. Thus, workpieces and particularly large workpieces can be uniformly ground within a short time and a multi-purpose grinding can be made.
