Our ID Grinders & Polishers are maintained to tolerances closer than .0001 to refinish consistently flawless Cam Rings, often resulting in efficiencies higher than new unit specifications. The quality of our refinished rings are second to none.

Surface Grinders refinish components with wear exceeding the limits of flat lapping. With our extensive manufacturing experience, many components with cavitation marks or material removed from aeration can be welded, re-ground, flat lapped then re-nitempered back to OEM specifications.
