Description

technical field [0001] The invention relates to a process and a machine tool for machining nut raceways, which belong to the field of mechanical manufacturing. Background technique [0002] Screw nuts are common and even indispensable basic moving parts in the industrial field, especially in the field of machine tools. However, the processing of the inner raceway of the nut, especially the raceway of the large-lead nut, has always been a difficult problem. At present, the general method of processing the nut raceway is to turn the raceway first, then quench the raceway to improve the hardness, and finally grind the raceway. [0003] There is also a process in foreign countries that uses the internal whirlwind milling cutter finishing process. Its principle is similar to grinding, but the efficiency is increased by 10 times by using a CBN milling cutter instead of a grinding wheel. However, when these two processes are used to process nuts, especially large-lead nuts, there ...
