Burnishing Guide: Roller, Ball & Diamond Burnishing for Smooth, Hard Surfaces

Burnishing Guide: Roller, Ball & Diamond Burnishing for Smooth, Hard Surfaces

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.

Preguntas frecuentes

What is burnishing?

Cold-working the surface smooth without removing material.

Burnishing vs polishing?

Burnishing compresses; polishing cuts material away.

Does it harden the surface?

Yes — it work-hardens and raises fatigue strength.

What shapes can be burnished?

Shafts, bores, rollers and radii on turned parts.

Do you supply burnish stock?

HXSCO supplies bar and turned parts ready to burnish.
