Machine tool for the fine machining of hardened large gears

摘要

The object of the invention is to create a machine tool in which productive machining is made possible with minimum effort for the orientation and clamping of the workpieces. According to the invention, the object is achieved by a milling tool holder 12 being arranged opposite the grinding tool holder 2 at right angles or in parallel. The workpiece is clamped on the rotary table 10 of the carriage 8. As a function of a hobbing cutter 15, a form cutter 22 or a side cutter 24, the NC axes for the translatory and rotary component of the generating motion 16; 17 of the carriage 8 or the rotary table 10 are connected with the NC axes of the axial feed motion and the rotary movement of the milling cutter 23; 25 in order to carry out the precision milling. For the subsequent generation grinding by the indexing method, the NC axes for the translatory and rotary component of the generating motion 16 and 17 of the carriage 8 and the rotary table 10 are interconnected. <IMAGE>
