Quality Control

1.Launch micro dimension inspection technology research for bearing parts

We have launched the study on the measurement Technology of Micro Geometric Precision of ring  raceway surface and the independently developed micro-scale waviness detection system and achieves  the nano-level to the micro-geometric precision resolution.It is critical for high speed machine  tool  bearing manufacturing and development.

4.The whole process quality traceability management

All the key products are numbered,and the information of each process distributed in the field is collected by scanning, and the production process, bearing model, product processing status, processing and quality status information of the processors, inspectors, processing procedures, The management terminal synchronously displaying and backing up to form a quality control network that covers the whole process.The product tracks the quality from the grinding process to the entire process of the user using to form a quality archive with traceability.

5.High quality processing production line

(1)high precison storage

The final grinding of all ring surfaces use the world's most advanced bearing processing technology and its most advanced processing methods.The processing level of its products can reach P2 level,  and has a certain degree of precision reserves;

(2)high precison surface quality

Super working of ring surface has adopted the world's most advanced ultra-precision bearing  technology and its most advanced ultra-precision oilstone processing methods,which effectively  improve the raceway surface geometry error and roughness.

(3)high quality online inspection system

High-quality closed online testing system can effectively improve the quality control of bearing parts processing to ensure stable and reliable processing quality.
