• Roughness   < Ra1nm
• Flatness  < 0.05um(100diameter)
• Parallelism < 0.5um
• Size tolerance  +/- 0.3um

our expertise is...

precision lapping, precision polishing, precision grinding, any other precision machining.

Our mirror polishing technology make the surface like a mirror, and achieve ultra flatness, parallelism, size tolerance, at the same time.
