Short answer: Burnishing cold-works the surface of a metal part with a hard, smooth tool — a roller, ball or diamond — that plastically deforms the asperities into the surface instead of cutting them away, producing a mirror-like, work-hardened, low-friction finish without removing material. It raises surface hardness and fatigue strength, seals porosity and eliminates the swarf and coolant of polishing, making it ideal for hydraulic rods, shafts, bores and medical and food-contact components where a clean, tight-tolerance surface is required.
