High precision through equipment introduction - Zygo laser interferometer, ultra-precision surface grinder.
The introduction of an interferometer that measures within one of the largest measurement ranges in the country with nanometer precision, along with a super-precision surface grinding machine equipped with oil hydrostatic guidance and precision machining systems, has achieved high precision in products.
With the new introduction of the "Zygo laser interferometer" and "ultra-precision surface grinding machine," we are now able to deliver ceramic parts and metal matrix composite (MMC) parts with even higher precision. We also meet the advanced demands of cutting-edge fields such as "semiconductors" and "space." We provide optimal solutions from our extensive lineup. Please feel free to consult with us. ■ Laser interferometer: Evaluates surfaces of up to 450mm x 1,000mm with nm precision, one of the largest in Japan. ■ Ultra-precision surface grinding machine: Ultra-high precision (below 1μm) with versatile shape processing (straight, flat, uneven, etc.).
