The process describes how transmission gears (6) can be manufactured in a highly economical and highly precise manner. In one single mounting, the complete hard fine-machining on all of the most important functional surfaces of the workpiece is conducted simultaneously. This multi-process is made possible through the combined use of a continuous generating grinding process for the machining of gearing, a known method for the machining of the boring and possibly of a frontal surface, and the fixing of workpieces (6) on form elements such as chamfers or plane surfaces by means of centering elements (9, 10) which are designed in such a way that they do not block the free access of the individual tools (5, 11, 28) to the surfaces (7, 8, 27) to be machined.
Process for fine machining of functional first surfaces on pre-machined and hardened transmission gear workpieces with a cylindrical boring, said first functional surfaces comprising a gearing, wherein in one and the same fixing of said workpiece on second surfaces not requiring hard machining, said gearing according to a continuously working generating grinding process and, at the same time, said boring are machined.
