[Processing Results] Production of Large Stainless Steel Mirrors for Fusion Experimental Reactor Development
Large toroidal-shaped mirror made of metal material SUS316L for the development of the nuclear fusion experimental reactor (ITER)!
We would like to introduce our processing achievements of the "Large Stainless Steel Mirror." Our company has manufactured a large stainless steel mirror made of SUS316L, which is being developed as a measurement device for the nuclear fusion experimental reactor (ITER). (Mirror size: 442×332mm) The toroidal shape measurement is conducted using a three-dimensional measuring machine. 【Overview】 ■ Mirror size: 442×332mm ■ Material: SUS316L ■ Shape accuracy: PV 5.7μm, Sq 0.841nm, Sz 68.883nm ■ Measuring instrument: Zeiss CONTURA AKTIV 7/10/6 (using HOLOS Program) *For more details, please refer to the PDF document or feel free to contact us.

Company information
Our company, at the time of its founding, was engaged in the hand polishing of optical single crystals. Among optical crystal materials, there are extremely delicate materials that can only be polished in environments with strict control of temperature and humidity. Based on this polishing technology, we have been involved in the polishing of various materials up to the present day. Now, after 30 years, we have expanded our capabilities to handle not only single crystals but also all kinds of materials including metals, non-metals, and ceramics. Initially, we processed small components that could fit in the palm of a hand, but today we are capable of handling ultra-large components up to 8000mm. In terms of our business (processing), we are focusing on in-house integrated production to achieve higher precision processing. We have established six fields: cutting, grinding, polishing, ultra-precision processing, surface treatment (non-conductive treatment/electropolishing), and measurement, allowing our customers to provide just one drawing and entrust all processing to us. In November 2014, with the aim of engaging in the aerospace industry, we introduced two new 5-axis composite machining centers, and we will do our utmost to contribute to the aerospace industry, which promotes the evolution of space.
