To achieve the final level of precision on many parts they also pass through our finish grinding department. Grinding machines make the removal of single “thousandths” or even “ten-thousandths” of an inch of material almost trivial matters (0.001” to 0.0001”). Grinding is applicable to almost any metal in its ability to generate precision surfaces which are flat, parallel, smooth, etc. Our toolroom surface grinder is a very versatile machine, capable of being repurposed to finish a variety of part features.

Beyond the capability of our surface grinder to finish precision flat planes and parallel surfaces, we can also generate angles and diameters. We have a range of accessories for grinding simple or compound angles onto parts. And we frequently use various toolroom spindles and indexers to rotary grind precision diameters and features with angular spacings down to arc-second resolution. When required we can also generate precision 2D form profiles and grind those contours using a few different methods.

Grinding is not limited to metals, though tool steels are the most common materials seen. And depending on application, even non-magnetic metals may be ground on our equipment. Despite grindings’ ability to produce extremely accurate results if your application requires further precision, then we can have a conversation about various options like Flat or Round Lapping, Honing, Burnishing, or Scraping to achieve your desired result.

Generally, the work which flows through our grinding equipment fits in a 6” x 15” frame and is usually shorter than 6”, where most of the parts fit in the palm of your hand. Our spin-grinding capacities in-house typically stay in the sub-2” diameter range but go all the way down to very small pins. If our equipment is not suited for a particular job, then we have vetted suppliers for both larger flat and round grinding work.
