Abstract

An improved polishing method utilizing a film of abrasive on metal laps is described. The abrasive film provides a greater number of active cutting particles than a fixed abrasive and does not give a surface with scratches and waviness such as is produced by a freely rolling abrasive. With this technique, a mounted surface can be ground and polished in less than an hour. Only two abrasives are used and the resulting surface is free from scratches and relief. The principle of the abrasive film is discussed. Problems concerning laps and abrasives are considered, and a detailed outline of the procedure is given.
