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.

What is 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.

The requirements of internal grinding vary depending on the industry, the application, and your specific needs, but in all cases, this type of grinding offers unbelievable results.

Thread grinding is a key service under the internal grinding umbrella of services. This type of internal grinding is applied to ball screws, cavities, medical bone taps and worms and core pins (electrodes).
