Abrasive Lapping Powder & Polishing Powder Description a) Lapping is a machining operation, in which two surfaces are rubbed together with a fine abrasive between them, by hand movement or by way of a machine. b) This can take two forms. The first type of lapping (traditionally called grinding), typically involves rubbing a brittle material such as glass against a surface such as iron or glass itself (also known as the lap or grinding tool) with an abrasive such as aluminum oxide, emery, silicon carbide, diamond, etc., in between them.
A pressurized fluid, typically air, or a centrifugal wheel is used to propel the blasting material (often called the media). The first abrasive blasting process was patented by Benjamin Chew Tilghman on 18 October 1870. There are several variants of the process, such as bead blasting, sand blasting, sodablasting, and shot blasting. In addition, there are alternative non-abrasive blasting methods in ice blasting and dry-ice blasting.
