Introduction to surface finishing (mirror finish) and groove processing - Surface Microfabrication Technology Handbook
Achieving high-quality fine processing with slit dies, adsorption stages, mirror surface processing, surface textures, etc. Free distribution of processing technology and case study booklets for grinding and ultra-precision cutting is currently available.
Our company offers contract processing services for high-precision and high-quality surface micro-machining. We are currently providing a handbook that introduces our "grinding processing technology," which achieves high precision in surface roughness, flatness, and straightness, as well as our "ultra-precision cutting technology," which performs high-precision mirror finishing, micron-order fine groove patterns, sub-micro needles, surface textures, and other shape processing. We can also handle fine machining of difficult-to-cut materials, ceramics, and brittle materials like glass. Furthermore, we have included examples of products utilizing the processing technologies introduced here. 【Product Processing Examples】 - Products using grinding processing technology ■ Slit die Surface roughness: Ra 0.03 μm, Flatness: 2 μm, Straightness: 3 μm Grinding machine owned: Nagase Integrex (SGC series) ■ Adsorption stage Free design of adsorption area, washable, excellent adsorption and release properties, control of adsorption marks - Products using ultra-precision cutting technology ■ Mirror finishing Surface roughness: Ra 0.02 μm or less ■ Sub-micro needle Achieves sharp tips and high aspect ratios ■ Surface texture High-precision tool shape transfer through relative motion between the tool and workpiece *For more details, please refer to the PDF document or feel free to contact us.

basic information
■Slit Die It is required to discharge the coating liquid with a uniform and stable film thickness, making the surface accuracy of the mating surfaces and slit accuracy important. We achieve high-precision processing by utilizing high-precision surface grinding machines and years of accumulated know-how. ■Adhesion Stage It is widely used for fixing thin film sheet-like workpieces such as single-layer films and semiconductor processes. It excels in workpiece adhesion performance and release properties, controls adhesion marks during adhesion, allows for free design of adhesion areas, is washable, and has excellent maintenance. ■Mirror Surface Processing Mirror finish is required on mold surfaces for optical applications. By applying ultra-precision cutting technology, we can achieve a surface roughness of Ra 0.02 μm or less. ■Sub-Microneedle We have realized sharp and high-aspect sub-microneedles by applying ultra-precision cutting technology. Based on the know-how we have cultivated so far, we will challenge the production of ultra-fine shapes that have not been processed before. ■Surface Texture With ultra-precision cutting technology, the tool shape can be accurately transferred through the relative motion between the tool and the workpiece. *For more details, please refer to the PDF document or feel free to contact us.*
