Minnesota Grinding, Inc. offers centerless grinding services, a precision grinding method for achieving roundness, surface finish, and dimensional tolerances among the best available in metalworking. This service is ideal for high-volume projects involving a variety of metals and some plastics, resins, and composites. The process, which is different from cylindrical grinding, does not mechanically constrain the workpiece, relying instead on the relationship between the grinding wheel, regulating wheel, and work blade. Industries such as aerospace, automotive, motion control, and transportation commonly require these high-precision services. Call (763) 535-4445.
