We realize ultra-precision manufacturing with our unique ultra-precision/wrapping processing technology!
At TDC Corporation, we base our operations on ultra-precision mirror finishing technology, enabling us to achieve sub-nanometer level surface roughness, sub-micron level flatness, parallelism, and dimensional accuracy. Not only do we realize individual precision, but we also excel in achieving complex precision. We accept polishing of not just flat surfaces, but also curved surfaces, spherical surfaces, and both inner and outer diameters. In addition to precise polishing, we are also skilled in general machining processes such as "cutting," "grinding," and "shape processing." With our comprehensive processing equipment and years of accumulated know-how, we are ready to respond to your overall manufacturing inquiries. 【Processing Technologies】 ■ Ultra-precision polishing / Lapping ■ Cutting / Grinding *For more details, please refer to the PDF document or feel free to contact us.

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.
