Abstract
The method and apparatus relates to the production of turned workpieces on multi-station machine tools. In such machines rod stock is introduced into a clamping device (collet chuck) of the machine and is clamped thereby. A rod section is severed at a distance from the clamping device and the free end protruding from the clamping device is turned. In such a process a section from the rod stock is introduced into the clamping device, clamped fast there and severed, which section comprises a multiple of the machining length and in addition a clamping section sufficing for the clamping of one single machining length section. This multiple section is moved by sections corresponding in each case to the machining length section out of the clamping device. The rod stock is clamped fast during turning over a following machining length section in each case, the last machining length section being clamped fast by means of the provided additional clamping section. The machined workpiece is sawn from the clamped-fast residue of the multiple section in each case.
