Grinding is the traditional final metal finishing operation performed on engineered metal-to-metal contact surfaces such as roller bearings and some gears. It results in a surface with a unidirectional pattern that corresponds to the direction of the final grinding operation.
Grinding wheels with different grit sizes achieve rougher or finer grinding passes, according to the needs of the application. When precise accuracy and/or surface finish are required, grinding is often used as a finishing process after some other metalworking operation.
These two finishing operations begged the question: when should grinding be used and when should EDM be used as a finishing process? To meet tight tolerances and surface finish requirements, tool manufacturers usually opt for grinding as a finishing operation because it's fast and efficient.
The milder abrasives like 32 and 38 Aluminum Oxide are best for lighter precision grinding operations on steels and semisteels, while the intermediate 57 and 19 Aluminum Oxide abrasives are used for precision and semiprecision grinding of both mild and hard steels. The severity of the grinding operation also influences the choice of grade.
