Research on outer circle polishing of platen workpiece

Abstract

With the improvement of assembly performance of platen workpiece, the roughness of outer circle of platen workpiece is required to be Ra 0.4. As the workpiece is turned on a CNC vertical lathe, the original level is about the surface roughness Ra 0.8 to Ra 1.3, which cannot meet the performance requirements. In this paper, the outer circle polishing device is developed, which is installed on the cutter tower of the finishing outer circle machine tool. After finishing the outer circle, it directly polishes the outer circle to the roughness of Ra 0.4.The workpiece after using the device structure can fully meet the accuracy requirements.
