Grinding equipment creates finishes for precision pieces using an abrasive material. Grinders take on many different types from flat grinders surface grinders or a machining process for very hard materials. To find out more about grinders visit Modern Machine Shop.
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.
