Centreless OD Burnishing Machines are high-efficiency finishing systems designed to burnish the outer diameter (OD) of cylindrical components without the need for a center or chuck. Ideal for mass production, these machines offer uniform surface finishes, improved dimensional accuracy, and increased component durability in one fast, automated process.
The machines use hardened rollers to apply pressure to the rotating part’s surface, plastically deforming micro-peaks into valleys. This results in a smooth, mirror-like finish without material removal. They are widely used in the automotive, bearing, and hydraulic industries where consistency and production speed are critical.
Centreless OD Burnishing Machines are engineered for robustness, ease of operation, and low maintenance. They can handle a wide range of component diameters and lengths with rapid changeovers and flexible setups.
Ask for catalogueHow It Works?!
The part is passed between a rotating burnishing roller and a support roller or shoe, with consistent pressure applied throughout the circumference. The rolling action cold-works the surface without any material removal. Unlike grinding or polishing, the surface is hardened and leveled using deformation, producing excellent roundness and finish in one pass.
