Exhibits full potential for high-efficiency, ultra-precision cutting in planar and cylindrical shapes
Ideal for fine grooving such as that for Fresnel lenses
■ Features 1. Drastically reduces or eliminates running-in machining time. 2. Obtain uniform, high-quality machined surfaces by setting the roundness (sharpness) of the cutting edge according to the work material and cutting conditions. ■ Applications 1. Laser reflective mirrors 2. Polygon mirrors 3. Photosensitive drums of copying machines 4. Planar and cylindrical mirror finishing
■ Features 1. The cutting edge is uniform and extremely sharp, free from chipping and undulation. 2. Guarantees the cutting edge shape in the order of submicrons.
■ Applications 1. LCD prism sheet moulds
2. Fresnel lens moulds 3. Optical sheet moulds 4. Various diffraction grating moulds 5. Other fine grooving
