Roller Burnishing

ECOROLL is the world leader in developing burnishing technologies.

• Produces mirror-finish surfaces
• Achieves a high surface bearing ratio
• Increases hardness, decreases friction and wear
• Short cycle, complete processing in one setting

Burnishing cold works the surface of a work piece. One or more rollers or balls are pressed against the surface of a work piece, plasticizing the material’s top layer, compressing the peaks and filling in the valleys.

This cold working not only provides a highly polished surface, but also results in enhanced performance characteristics, such as increased strength and resistance to stress corrosion cracking.

Selecting the Right Tool

Burnishing Tools are available in several different configurations, depending on the application.

The ECOROLL Tool Selection Guide (PDF file) can help you choose the right tool for your application.

Multiple Roller Tools are designed for cylindrical bores (both through and blind holes), stepped bores and internal and external cylinder surfaces.

Single Roller Tools are designed to machine a wide variety of irregular surfaces, including specific contours, fillets, and grooves as well as cylindrical and tapered external surfaces and bores.
