Research on scan polishing flat surfaces with a small diameter tool

Abstract

High profile accuracy and high surface quality, which are achieved by stable polishing velocity, are needed in the machining of NiP neutron reflection mirror along with suitable machining tools. To respond to the growing demands for high quality reflection mirrors, in this study, a small diameter polishing tool was used on a three-axis CNC ultra-precise polishing machine. Mathematical models of polished profiles based on the Preston equation were built and discussed along with the simulation results of the polished profiles. These models of polished profiles were proved to be effective by numerous experiments under diverse conditions. The polishing characteristics of electro-less plated NiP surface were reviewed, and smooth surfaces could be achieved by scan-type polishing.
