About Us

1960, Downey Grinding has provided centerless grinding services with unbeatable quality and delivery at a competitive price.  We consistently maintain tight tolerances and provide superior finishes on parts in virtually any material.  Our grinding capabilities include spherical radii and full balls, as well as grooves, flats, and, multiple diameter shafts.


To maximize production efficiency, we maintain 15 fully automated grinders.  We also perform centerless crush grinding for intricate forms on small parts and for grinding O.D. threads on thin wall bushings.  A 5,000 gallon centralized oil system filters and cools oil for optimum quality and surface finish.


Quality Assurance

Our quality assurance program conforms to both MIL-I-45208A and MIL-STD-45662, while Statistical Process Controls maintain quality and consistency throughout the production process.


Quality control department includes four optical comparators with digital readouts that measure tolerances to .00005".
