A double lead rolling linear feed system applied in a special grinding machine for sliding block is introduced:its working principle and structure characteristics are elaborated,and the static and dynamic characteristics of the y axis feed system in the slider special grinder are simulated and analyzed in Workbench simulation software.The analysis results show that the maximum stress of the feed system is about 1.65 MPa in terms of static characteristics,the maximum deformation is about 11 μm,located at the far right end of the second workbench,and the deformation at the grinding wheel is about 4.2 μm;while in terms of dynamic characteristics,the first order natural frequency of the feed system is about 138.34 Hz,and the maximum amplitude is located in the secondary feed drive section,which has better dynamic characteristics compared with the traditional ball screw feed system.The analysis on the static and dynamic characteristics of the double lead rolling linear feed system is conducted in design stage,which provides theoretical support for structural optimization design of the feed system and guiding prototype production.
