Case

Mirror polishing Rmax 0.5 - 0.7 or less. Cylindrical grinding Rmax 0.5 or less, Centerless polishing Rmax 0.8 or less

With automation of the machines, de-burr, surface polishing and grinding are automatically performed during cutting, which reduces variations in quality due to hand work, greatly reduces the number of processes with one chucking and contributes to a central control. Surface roughness that has undergone surface treatment, polish, lapping, centerless and cylindrical polishings after grinding and cutting is Rmax 0.8 or less. We continue to challenge the limit.
