The Difference Between Round Bar and Precision Ground Bar
Round bar is exactly as it sounds; a long, cylindrical metal bar. Round bar is available in many different diameters ranging from 1/4″ up to 24″.
Precision ground bar is manufactured through induction hardening. Induction hardening is a non-contact heating process which uses electromagnetic induction to produce the required heat. Centerless ground bar is typically produced by turning and grinding the surface to a specified size.
Precision Ground Bar, also known as ‘Turned Ground and Polished’ shafting, refers to round bars made with fine precision and high-quality steel. They are polished to ensure flawless and perfectly straight surfaces. The manufacturing process is designed for extremely close tolerances for surface finish, roundness, hardness, and straightness which ensures a long service life with reduced maintenance.
