Each batch of raw material steel is inspected and classified according to different material (carbon, stainless, chrome), size and quantity, which marked with the Material Cert. The qualified steel comes to the quarantine area; the unqualified will be rejected with a record.
2. Wire Drawing
The steel is made into different sizes according to the needed requirements.
The raw material certified is worked on high-speed casting machines to cast into different size pieces.
This step of the production process involves rolling the pieces between discs with concentric grooves to eliminate signs of casting and to increase the precision of the ball.
5. Heat Treatment
Heat treatment, where necessary, gives the balls the maximum possible hardness and the best technical characteristics that can be achieved with the materials used.
6.Lapping i (Grinding)
Successively several careful grinding processes using ceramic grinding wheels give greater dimensional precision and prepare the balls the next, final lapping process.
7. lapping ii
This procedure gives the ball a perfectly shiny, compact and defect-free surface, with very low surface roughness, much lower than that required under GB/308-2002
8. Selecting and Final Inspection
The sorting machines together with the manual
detecting and modern testing processes, largely ensures the high quality of our products.
We will pack the balls as per customers’ requirements.
