[Processing example]　Introduction of "burnishing" which achieves high surface roughness through turning.

・About burnishing
A type of lathe processing in processing methods. This method uses a special tool such as a burnishing roller instead of regular cutting.

A burnishing roller is a cylindrical roller that has multiple cutting edges and grooves around the outside edge. By pressing and revolving this roller on the surface of the workpiece, the material is crushed rather than scraped. This machining method is different from traditional cutting and can reduce shavings and vibration generated by frictional heat.

Burnishing is particularly suitable for ring-shaped parts and products that require high surface roughness on the outer diameter surface of a cylindrical shape. For example, high-pressure hydraulic parts and bearing outer rings. This method is effective in improving machining accuracy and surface finish quality. It is especially widely used in industrial fields where precision machining and high-quality finishes are required.

【Burnishing】
After finishing the surface roughness to 6.3 seconds or less by turning, we use a special tool to reduce it to 3 seconds or less.
If surface roughness of four peaks (▽▽▽▽) is required but dimensional accuracy in the micron range is not required, the grinding process can be omitted.

This is a highly cost-effective processing approach.
