CAM machine - CNC machine - 6 axis nc machine constantly upgrading, not only improves the production efficiency more than 5 times, but also control of blank dimension precision.

Through quenching、deep cooling and tempering, reduced the surface decarburization of inner and outer wheel blank, enhanced the metallographic structure of metal, and increased the wear-resisting life of products.

First domestic factory using the most advanced vertical plane grinding machine to ensure the accuracy of processing datum width 
width processing accuracy :-11.5~-13.5μ 
JIS and national standard :0~-40μ

The automatic raceway superfine grinding equipment which is independently developed and manufactured by the company is suitable for the processing of special miniature bearings. It ensures the products have the effect of super-quiet when running.
Channel superfine roughness < 0.01μ

真空碳氢清洗确保轴承的清洁度。

Independently developed and manufactured the automatic assembly、 adding ball、greasing and cap fitting equipment
has been independently designed and upgraded. After 5 generations, the production efficiency has been doubled.
