Centerless grinding is a high-productivity process used to machine cylindrical parts and workpieces without the need for centers, making it ideal for mass production of shafts, rollers, bearing components, and automotive parts requiring consistent diameter accuracy and surface finish. It is especially effective for high-volume manufacturing where throughput, repeatability, and process stability are critical.
So what types of parts are best suited for centerless grinding?

Definition of Centerless Grinding

์„ผํ„ฐ๋ฆฌ์Šค ์—ฐ์‚ญ์˜ ์ •์˜

Centerless grinding is a precision machining process used to grind the outer diameter of cylindrical parts without the need for centers or chucks. The workpiece is supported between a grinding wheel and a regulating wheel, allowing continuous processing with high productivity and consistent dimensional accuracy.

This process is particularly effective for mass production of shafts, rollers, bearing components, and automotive parts that require stable diameter control and uniform surface finish. Because it enables high throughput with excellent repeatability, centerless grinding is widely used in industries where both precision and production efficiency are critical.
