Abstract:In order to improve the processing accuracy and efficiency of rotor spinning machine shell，the main problems existed in milling and boring process for the parts in machining center are analyzed，such as many processing contents，complex forming，difficulty in choosing boring cutter and large consumption of rod milling cutter，which led to low efficiency and poor accuracy.The newly designed NC turning process scheme is introduced from the aspects of process，equipments，fixture，cutters and program，and the process improvement effect is verified.Production practice shows that the newly designed NC turning process adopts a positioning method of one plane and two pins，uses NC lathe based on many cutters and appropriative positioning fixture，introduces modular power end-face slotting cutter and Plansee boring cutter，and applies optimized NC program and so on.The qualified rate of the rotor spinning machine shell stays above 99%，and production efficiency increases 3～5 times with the newly designed NC turning process.The primary condition of NC turning is to unify the advanced cutters with the optimized NC program，and improve machining effect continuously in production.
Key Words:rotor spinning machine；shell；boring and milling；precision；efficiency；NC turning；end-face slotting cutter；one plane and two pins
