Burnishing

Burnishing is a finishing process where a hard, smooth tool rolls or rubs over a workpiece surface without removing material. By plastically deforming the top layer, it flattens micro-peaks, reduces roughness and improves wear and fatigue resistance while producing a bright, uniform finish.

Here you’ll find burnishing tools for lathes and CNC, with roller or ball heads, for internal and external surfaces, in various diameters and geometries. Options include robust heads and easy pressure adjustment, from Zeus.

Common applications include shafts, bearing seats, guides and hydraulic parts where consistent surface quality and repeatability matter. Choose based on workpiece material, hardness and the target roughness.
