The production process
The quality of products is guaranteed by the use of an innovative control system. A certified testing laboratory also exists and is actively operating at the enterprise. It is necessary to control the compliance of the workpieces with chemical composition and geometric parameters. The laboratory also evaluates the quality of grinding balls. This provides the opportunity to test the metallurgical products that are supplied to customers. This approach is prescribed in the requirements of world standards. During the production chain several balls are taken from each batch. In each measured volumetric and surface hardness.
Grinding balls are classified according to the hardness indicators:
1 – normal hardness;
2 – increased hardness;
3 – high hardness;
4 – high hardness with normalized hardness at a depth of 0.5 radius of ball.
