Precision Grinding

Centerless Grinding Services (OD)

Centerless grinding is an OD grinding process. It differs from other cylindrical processes in that the workpiece is not mechanically constrained.

We can perform Centerless Grinding services for the large number of metal parts you may want grinded within a short period of time. Centerless Grinding is definitely the way to go if you have a large number of parts and components that need to be shaped and grinded. We offer high precision Thrufeed and Infeed centerless grinding for workpieces. With Thrufeed centerless grinding, we are able to work with workpieces with consistent roundness in the length of the workpiece. In Infeed centerless grinding, XSH can grind cylindrical workpieces with complex shapes and or tapers to stringent tolerances.

Cylindrical Grinding Services (OD & ID)

Some components having complex geometries or featural relationships that cannot be grinded by the centerless grinding process, but we will use our precision cylindrical grinders to handle.

XSH 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.

Precision ID/OD grinding provides better part-to-part consistency over similar, alternative turning processes, especially for parts with size, roundness, concentricity, and surface finish requirements.

Surface Grinding Services

XSH surface grinding team has the experience and knowledge to assess the ideal ways to perform surface grinding operations and tailor every process to the needs of each part.

We can accommodate large surface material. Dimensional tolerances to +/- 0.003mm can be accomplished. Surface grinding is ideal for material with a large surface and reducing cost by surface grinding multiple units at the same time. This can be achieved with stringent tolerances.

At XSH, we welcome all types of surface grinding jobs, from simple or flat surface grinding to the most complex parts. We look forward to meeting and exceeding your expectations every time.
