Steel Balls Fine-Lapping Process
Steel balls fine-lapping process is using two cast iron plates which add chromium trioxide and other soft grinding materials to lapping the steel balls.
After fine-lapping, the surface roughness, diameter variation and the surface profile of steel balls are better than after grinding processing.
Steel ball fine-lapping process method is basically the same as fine grinding process, it can divide into large circle lapping, large circle lapping, single-disc closed lapping.
