A centerless ground bar is a precision metal bar manufactured through the centerless grinding process, where abrasive grinding wheels remove material from the outer diameter of a cylindrical workpiece to achieve high dimensional accuracy and a smooth surface finish. Unlike traditional grinding methods, this process does not require a spindle or fixture to hold the bar. Instead, the workpiece is supported between two rotating wheels that control the grinding and feed rate, allowing consistent material removal and excellent roundness.
Industries that require tight tolerances and reliable material performance often rely on centerless ground bar products for manufacturing precision components. The centerless grinding process improves straightness, roundness, and surface quality while eliminating many surface imperfections. This level of accuracy makes the centerless ground bar ideal for applications in aerospace, automotive, medical equipment, and precision machining.
