Abstract
This paper discusses lapping a metal mirror with solid abrasives at high speed. In this method there are three procedures. First the workpiece is ground in a grinding machine, which makes the surface roughness of the workpiece reach about Ra1.6micrometers . Second the workpiece is lapped roughly on a lapping machine, which makes the surface roughness of the workpiece reach about 0.1micrometers . Last the workpiece is lapped finely, which makes the surface roughness of the workpiece reach about Ra1nm. Because solid abrasives are used, the machining efficiency is very high. Each lapping procedure time is only about one minute. A high speed, high efficiency and accuracy machining is realized.
