Achieving a super mirror finish! Rz 0.2 μm even for irregular shapes, and Rz 0.03 μm for flat surfaces!
At Ohno Seiko Co., Ltd., our lapping process can achieve a mirror finish with Rz 0.03μm on flat surfaces and Rz 0.2μm or higher on irregular shapes. This precision has been realized through the pursuit of lapping agents and methods by our skilled technicians. We can process irregular shapes without compromising quality, so please feel free to consult us about any shape or surface roughness. Upon delivery, we will provide actual measurement values attached from our unique quality manual. We also have a wide range of measuring instruments, so we accept requests for shape and surface roughness measurements only. *For more details, please download the PDF or feel free to contact us.
