According to high speed lapping technology with solid abrasives this paper develops a new high speed lapping machine. The high speed lapping technology and the machine are combined into one system through this lapping machine. By means of this way the high speed lapping technology is used in production widely and a very good result has been got. Comparing traditional lapping, by new machine the machining efficiency is increased 30 to 100 times, the abrasives cost is decreased 90%, the machined surface roughness reaches Ra2.55 nm and the machined surface flatness reaches 0.2 μm(P-V), which realizes high efficiency and low cost nanometer lapping. These technology and machines are use by over 30 companies at home and abroad. Remarkable economic results and social effects have been achieved through the users.
