Abrasive Jet Machine

Description

Abrasive jet machine (AJM), also known as abrasive micro-blasting, pencil blasting and micro-abrasive blasting,is an abrasive blasting machining process that uses abrasives propelled by a high velocity gas to erode material from the work piece. It is one of the advanced machining processes where a high velocity jet of abrasives is utilized to remove material from work surface by impact erosion. The abrasive jet is obtained by accelerating fine abrasive particles in highly pressurized gas (carrier gas). A nozzle is used to convert this pressure energy into kinetic energy and also to direct the jet towards work surface at a particular angle (impingement angle). Upon impact, hard abrasive particles gradually remove material by erosion and sometime assisted by brittle fracture. Common uses include cutting heat-sensitive, brittle, thin, or hard materials. Specifically it is used to cut intricate shapes or form specific edge shapes.
