Basics of roller burnishing

Roller burnishing is the economical, simple and reliable manufacturing of maximum surface quality while increasing the strength and hardness of the workpiece.

Baublies AG defines roller burnishing as a generic term for deep rolling, fine rolling, etc.

Roller burnishing is a non-cutting process for smoothing and strengthening (metallic) workpieces by means of rolling elements.

During roller burnishing, one or more rollers are subjected to a force directed vertically to the running surface (rolling force). Thereby the roughness profile is plastically deformed and levelled.

In this fine machining process, the stress state in the surface layer of the material is changed.

ADVANTAGES

• Mirror-like surfaces with roughness below 1 μm and high material load-bearing capacity
• Reduced risk of crack formation due to micro-notches (e.g. turning grooves)
• Improved wear characteristics compared to other components (e.g. seals, bearings) due to the high proportion of material on the surface
• Improved corrosion resistance due to reduced surface exposure
