Surface, Internal and Cylindrical Grinding Creates Perfectly Machined Components

We offer superior quality surface grinding, internal grinding and cylindrical (ID/OD) grinding services.

CNC Grinding Services MilwaukeeAllis Tool & Machine grinding services achieves required dimensional accuracies and surface finishes for demanding applications—with tolerances within only thousandths of an inch. Computer numerically controlled (CNC) grinding puts incredible power behind highly precise operation.

The Allis Tool CNC Grinding Machines

We are equipped with multiple surface grinding machines that can accommodate large parts with flat surfaces in sizes of up to 24 x 60 x 20 inches and can grind surfaces to tight tolerances of about 0.00005 inch. Custom programming heavy duty CNC tooling allows for silly precise cuts that would be impossible otherwise.
