Precision Grinding

Precision grinding removes material with an abrasive wheel instead of a cutting tool, taking a part to a finish and size that milling and turning cannot reach. Outside and inside diameters are ground round and to size. Flat surfaces are ground flat and parallel. Jig grinding finishes precisely located holes and complex contours in hardened material. Lapping takes a surface even further, bringing flatness down into the low millionths of an inch. For hardened steel, wear surfaces, and mating components, grinding is often the step that makes the part work.

Precision grinding comes after a part is machined and heat treated, which makes it the stage where final size and geometry get locked in. The process holds tight dimensions on hard materials, produces consistent surface finishes, and pairs with in-house inspection to verify the result. Facilities across the platform cover OD, ID, surface, and jig grinding, and lapping for a level of flatness that not every shop offers.
