Grinding wheel wear - Wikipedia

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.
