Grinding Services

In-house CNC Grinding is a Tri Part distinction. We have 5 different grinding machines that give us the flexibility to provide thru-feed grinding, in-feed grinding, and OD grinding.

Grinding Capabilities

Tri Part has the capability to analyze over 20 surface finish parameters to meet tight tolerance requirements. Typical in-house grinding tolerance can reach .0001” for diameter, .0005” circularity, .0001” straightness, and 0 shaft lead (as per SAE J946).

Grinding Benefits

CNC grinding operations are crucial for producing parts that require extremely precise dimensions and superior surface finishes. The CNC grinding process involves an abrasive wheel that removes material from the workpiece with high accuracy, driven by computer-controlled settings that ensure consistent results. This precision is vital for parts with complex geometries or those made from hard materials that are difficult to machine using other methods. Additionally, CNC grinding minimizes the risk of defects and ensures a high-quality surface finish, which is necessary for components that must fit together perfectly or function reliably under stringent conditions.
