<p>Surface machining of long workpieces with round or profiled cross section is esp. applied to bar material where two rotating tools are supported diametrically opposite on a driven rotating block at a distance from the axis of rotation. The tools, during workpiece movement, are in contact with the workpiece. The tool drive is derived from a disc coaxial to the rotating block. Between each tool drive shaft and the static disc, is an intermediate gear, and gear and disc and gear and drive shafts are connected by drive belts. Each tool drive shaft is supported in a pivot arm which is supported on the gear shaft and can be fixed on the rotating block. Each shaft is also passed through a cut out in the rotating block, concentric to the pivot axis.</p> |
