Exhibits excellent performance in ultra-precision machining of spherical and aspherical surfaces.
The cutting edge arc profile 50 nm (0.05 μm) has been realized within a wide range of working angle 90°.
Also, the cutting edge ridge has been finished accurately without fluctuation to produce surface roughness in the order or nanometer.
The records of the profile of cutting edge arc measured by our original measuring equipment of 5-nm resolution are attached to ensure thorough quality control.
※The records may not be attached depending on the size of R.
