Ideal for Processing Fine Patterned Shapes such as Light Guides, Diffraction Gratings, Lens Arrays, etc.
Micro machining (micro grooving) is the cutting of periodic structures such as lines, curves, and dots on the surface of NiP and other workpiece using diamond tool. Typical examples include linear and cross prism processing for light guide plates and reflectors, Fresnel lens processing, and micro lens array processing. NAGASE's nano machines are used in a wide range of fields because they have features that maximize the advantages of cutting nano processing, such as "large area processing, excellent straightness, and good surface roughness.
