to diameter. The vessel is charged with the grinding media. The grinding media may be made of hardened steel, or tungsten carbide, ceramics like agate, porcelain, alumina, zirconia. During rolling of vessel, the grinding media & powder particles roll from some height. This process grinds the powder materials by impact/collision & attrition.
Compression Springs - End Squareness, Parallelism and Grinding
Compression springs with closed ends can often perform well without grinding, particularly in wire sizes smaller than .020 in. or spring indices exceeding12. Spring parallelism relates to the ends of the spring and how parallel they are to one another. A compression spring cannot be closed and ground so consistently that its ends will always be ...
