Precision Grinding

Precision ID/OD CNC grinding meets the needs of components having more complex geometries or featural relationships which cannot be served by the centerless grinding process. CNC grinding also provides the ability to grind a component’s internal features.

CNC Grinding offers better part-to-part consistency over similar, alternative turning processes, especially for parts with size, roundness, concentricity, and surface finish requirements.

Profile specializes in precision cylindrical grinding– that is, precision grinding inside diameters (IDs) and outside diameter (ODs) of cylindrical parts, excelling at those with multiple features, such as grooves, radii, and tapers. In some cases, form grinding may be utilized, where the component’s profile is formed directly into the grinding wheel.

To best manage our precision grinding processes, we utilize workholding methods which obtain efficient material removal for each part feature, while maintaining repeatable accuracy. These include internal (ID) grinding and external (OD) grinding workholding. Between-centers workholding is utilized when in-process support is beneficial, particularly for components with high diameter-to-length ratios.

Face grinding and limited surface grinding and honing services are also available.
