Chapter 28: Abrasive Machining Processes

28.1 Introduction Abrasive machining is the process of using abrasive grit to remove material at high cutting speed and shallow depths of penetration. The abrasive particles may be (1) free; (2) mounted in resin on a belt (called coated product); or, most commonly (3) close packed into wheels or stones, with abrasive grits held together by bonding material (called bonded product

The grinding wheels are cut out of the rolled sheet to a specified diameter and hole size. Scraps are kneaded, rolled, and cut out again. Then the wheels are vulcanized in molds under pressure in ovens at approximately 150 to 175°C (300 to 350°F). The finishing and inspection processes are similar to those for other types of wheels.
