Internal grinding has a reputation as being the most difficult and tedious type of grinding. It also requires a great deal of attention to detail and therefore many people worry that the job will not be done accurately. However, since Minnesota Grinding’s humble beginnings in 1959, we have been developing strategies that make all types of grinding simpler and more effective, including internal grinding.

This particular type of grinding involves finish grinding the bores or holes in some material. Typically, this material is a metal alloy, but we also occasionally do work with plastics and rubber.
