At Minnesota Grinding, we perform any number of grinding processes. Our highly trained and skilled operators understand the need to use the right grinder for the job. In some instances, they turn to ID grinding. This is typically called upon when the need is to finish off the inner surface of a workpiece – an action no OD grinder can address.

Components of an ID Grinder

An ID grinder is composed of several parts. Each plays a significant role in ensuring the ideal conditioning of the shape, form and the finish of the ID of a workpiece. Among those of particular importance are:

  • The Grinding Wheel
  • The “X” and “Z” slides
  • The grinding wheel spindle
  • The grinding wheel truing/dressing device
  • The work-head spindle
  • The coolant nozzle

Operators need to understand these mechanisms, as well as the need to ascertain factors that will affect the process including the type and hardness of material. It is also important to ensure the alignment of the involved parts of the ID grinding machine in order to produce the highest quality of work possible.

Basic Types of ID Grinders

Essentially, an operator can select one of three basic types of ID grinders to accomplish the task of internal grinding. He or she can choose a

  1. Chucking Type Internal Grinder
  2. Planetary Internal Grinder
  3. Hone

The choice will depend upon availability as well as other factors relating to the specifications of your project.
