Design and Analysis of A CNC Lathe for Repairing Car Wheel

Abstract

In this paper, the vertical lathe for repairing wheel surface is a special lathe for repairing wheel surface of aluminium alloy automobile wheel. It can carry out micro-turning on the wheel surface with intact body but with wear, aesthetic and slight scars. Static characteristic analysis of lathe lays a foundation for follow-up dynamic characteristic research and optimization design. And this analysis has very important theoretical and practical significance for improving the overall performance and design level of lathe. According to the different types of processing hub, four typical processing positions of NC lathe are determined to find the maximum loading position. Through the finite element analysis, it is determined that the third position is the most dangerous position among four typical positions, the deformation of the whole machine is the largest, and the maximum stress is the largest.
