Centerless grinding is a unique machining process that enables manufacturers to rapidly create high-quality precision parts. At EMC Precision, we invest in cutting-edge centerless grinding equipment to produce parts at tight tolerances down to ± 0.00005”. By utilizing robotic loading and unloading, this equipment lowers production costs while exceeding the precision and accuracy of conventional machining processes.
What Is Centerless Grinding?
Centerless grinding uses two wheels to remove material from a workpiece, resulting in a rounded final part. The workpiece, between the two wheels, stays in place on an angled workblade. Depending on the configuration, the workpiece can rest on the centerline or below the center of the wheels.
The larger, abrasive grinding wheel rotates at high speeds, removing material from the workpiece. The smaller regulating wheel adjusts the workpiece’s position by rotating more slowly. Together, these wheels shape the outer diameter of the workpiece into the desired final product.
Although the lack of center may seem to compromise the precision of the workpiece, centerless grinding is one of the most precise and controllable metalworking processes. The accuracy and speed of centerless grinding make it ideal for use across a range of industries and applications. Some products that are manufactured using centerless grinding include:
- Axles
- Bearings
- Bushings
- Balls
- Crankshafts
