The surface appearance of bearing steel balls is crucial. Poor surface finish directly affects the grade of the steel balls. So, what processes affect the surface finish of steel balls?
Condar explains: Multiple processes, including cutting, pressing, heat treatment, initial grinding, and final grinding, can easily cause surface defects such as burns, scratches, cracks, and rust on the steel balls.
If the steel balls rotate at high speeds and are subjected to pressure loads, these surface defects will gradually expand, causing fatigue peeling on the surface and leading to bearing failure. Therefore, surface appearance is a crucial criterion for precision steel balls.
We actively utilize modern advanced processing and grinding technologies and equipment to significantly reduce surface defects visible to the naked eye. However, subtle surface defects are often undetectable. In such cases, we utilize specialized surface inspection equipment, such as infrared inspection instruments, to effectively control surface defects in each batch of steel balls, achieving a 360-degree, comprehensive inspection of every particle, ensuring that you receive products with a perfectly finished surface.
