Hand Lapping / Polishing Plates
Standard Hand Lapping Plates
Lapmaster Hand Lapping Plates are ideal for research & development work and low volume production where extreme flatness is required. These plates are manufactured of dense, low porosity cast alloy to insure maximum cutting action, minimum plate wear, and consistent surface finish. These plates are lapped flat to within 1-2 lightbands (.000022") over 3 inches. They are available in three standard sizes of 6", 12" and 18" with crosshatched, serrated, or solid surfaces.
Alloy Polishing Plates
These plates have a cast base surface with a special alloy to insure minimum plate wear. Lapmaster Alloy Polishing Plates are recommended for soft materials such as carbon and plastic. When used with the proper polishing powder, consistent surface finishes of 1-2 microinches are obtainable. Lapmaster Alloy Polishing Plates are available in 6" and 12" diameters.
Ceramic Hand Polishing Plates
Lapmaster Ceramic Polishing Plates are specially designed for use with ceramic, tungsten, tungsten carbide and ferrite materials. These plates are made of solid ceramic (15/16") and are available in 6", 9" and 12" diameters.
