We achieve ultra-precision machining accuracy in almost all processing elements such as mirror finishing, flatness, parallelism, dimensions, spherical surfaces, curved surfaces, and angles.
We achieve not only mirror surface roughness but also high precision in flatness, parallelism, and dimensional accuracy simultaneously. We accommodate everything from one-off items to mass production as needed. It is possible to realize ultra-precise surface accuracy for all materials and shapes. 【Supported Materials】 ○ Metals → General steel materials, carbide, stainless steel, copper, titanium, aluminum, molybdenum, tungsten, nickel, tantalum, and various others. ○ Ceramics → Alumina, zirconia, sapphire, silicon, silicon carbide, silicon nitride, etc. → Polishing of coated surfaces such as thermal spraying is also possible. ○ Crystal Materials → General glass materials, silicon, SiC, sapphire, GaN, etc. ○ Resins → Various engineering plastics, polyimide, Teflon, etc. For more details, please contact us or download the catalog.

Company information
We specialize particularly in ultra-precision mirror surface processing, with a maximum size capability of φ1500 for single-sided machines. We excel in improving flatness, parallelism, and surface roughness for precision stages and suction plates. For suction plates around φ300*10t, we produce with flatness of 0.001, parallelism of 0.001, and Ra below 0.01 (for SUS material). For φ100*5t (materials such as SUS, Ni, Ti, Mo, Ta, W, ceramics, Si, etc.), we can manufacture plates with precision of less than 0.001 in flatness and around Ra 0.001, which are used as ultra-high precision jigs and molds. ◆ Selected as one of the 300 vibrant small and medium-sized manufacturing companies in 2007. ◆ ◆ Chosen as one of the "Global Niche Top 100 Companies" by the Ministry of Economy, Trade and Industry in 2014. ◆ Selected as a "Regional Future Leading Company" by the Ministry of Economy, Trade and Industry in 2018.
