The unsmooth movement of the steel balls in the disc caused by disc breakage also indirectly causes the out-of-tolerance of the roundness and the size requirement, so that the steel balls need to be pre-treated before disc breakage occurs. At each stage of steel ball grinding, damage is often caused by improper pressing of the grinding disc due to foreign matter falling in or human abnormal operation. At present, the main method for eliminating the damage of the grinding disc is to detect the damaged steel balls through a quality inspection stage and then inspect the damage condition of the grinding disc, however, the detection method has poor effect, is easy to produce a large amount of defective steel balls, and further generates excessive cost loss of defective products.

When the damaged line segment spectrum shown in fig. 7A is generated, the determination unit 41 may determine that the damaged position is located on the first polishing disk 10.
When the damage position is located on the second grinding disk 20, since the second grinding disk 20 does not rotate during the grinding process, the steel balls periodically pass through the damage position, thereby generating a stable damage frequency spectrum as shown in fig. 8.
Finally, the determining unit 41 can further determine whether the first polishing pad 10 or the second polishing pad 20 is determined according to the frequency difference, please refer to the following table:
watch 1
