Advanced Capabilities


    We specialize in external grinding, where a high degree of accuracy is required dimensionally and geometrically. Our craftsmen are able to accurately maintain roundness, straightness and cylindricity of 5 to 10 micro inches, while yielding a high quality surface finish that meets your specifications.


    Our internal grinding operations produce geometric accuracies in the 5 to 10 micro inches range with high quality surface finishes. We also have the ability to do common sizing work that matches OD’s and ID’s to within 5 micro inches. This capability is essential for applications such as air bearings and fuel injectors where matched fits yield performance advantages. Our tooling can handle parts up to 18 inches in diameter.


    Our surface grinding meets the most critical dimensional, geometric and location requirements. We are experts on thin parts, tapered parts, magnetic and non-magnetic materials.
    We often pair our surface grinding work with lapping and/or polishing operations to meet our customers most stringent requirements for flatness and surface finish.
