External roller burnishing tools are used to finish and harden the outer surface of cylindrical components such as shafts, rods, and pins. This non-abrasive process uses precision-ground rollers to apply controlled pressure, displacing surface material and creating a smooth, mirror-like finish without material removal.
The result is a highly wear-resistant surface that improves the performance and appearance of the component. The process enhances fatigue strength, reduces surface irregularities, and eliminates secondary operations like grinding or polishing.
External roller burnishing is ideal for parts requiring high surface quality, dimensional accuracy, and superior mechanical properties. Common industries using this process include automotive, aerospace, hydraulics, and general engineering.
Available from stock for nominaldiameters from 2 to 50 mm
Ask for catalogueHow It Works?!
External roller burnishing works by rotating a set of polished rollers against a rotating workpiece. As the rollers apply pressure, they plastically deform the surface layer, pushing material from high spots into low areas, producing a uniform, polished finish. No material is removed, making the process clean, fast, and precise.
Why Us!
We offer a wide range of external roller burnishing tools for various applications and diameters. Our tools are engineered for precision, ease of adjustment, and long operational life. Whether you're burnishing thin shafts or large industrial components, we have the right solution to ensure efficiency, repeatability, and exceptional surface quality.
Improved Surface Finish
Burnishing delivers a bright, polished surface with low roughness values without abrasives or polishing compounds.
Increased Productivity
The process takes only seconds per part, dramatically reducing production cycle time and eliminating post-machining operations.
Superior Wear Resistance
The cold working effect increases surface hardness and improves resistance to wear, scuffing, and fatigue.
Easy Tool Adjustment
Our tools are designed for quick setup and repeatable adjustment, accommodating various shaft sizes without the need for tool changes.
