Internal roller burnishing tools are precision-engineered instruments designed to improve the surface finish and dimensional accuracy of internal bores. These tools use hardened and highly polished rollers to apply controlled pressure on the inner surfaces of cylindrical workpieces, resulting in a mirror-like finish and work-hardened layer.
The burnishing process displaces material rather than removing it. Peaks on the surface are plastically deformed into valleys, forming a smooth, plateau-like structure. This improves surface contact, reduces friction, and extends component life, making it ideal for hydraulic cylinders, engine components, and precision bores.
Internal roller burnishing eliminates the need for secondary processes like honing or grinding. It enhances part quality, reduces production time, and is suitable for automated and manual operations across various industries.
Ask for catalogueHow It Works?!
The internal roller burnishing tool is inserted into a pre-machined bore. As the tool rotates, its rollers apply radial pressure on the inner surface. This pressure exceeds the material's yield point, plastically deforming the microscopic surface peaks into valleys, thus leveling the surface. This cold-working process not only smooths the bore but also increases surface hardness and fatigue strength.
