At TDC, precise internal diameter polishing and mirror finishing are also possible!
Are you having trouble with the surface roughness of the inner diameter? At our company, when we perform a mirror finish on the inner diameter of pipes, we not only polish them but also manage dimensions while achieving the mirror finish. *The product in the photo is a sample that has been cut in half after the mirror finish for clarity. The material in the photo is stainless steel, with a surface roughness of Ra2nm or less for the inner diameter. We can also handle materials other than metals without any issues. We accommodate a wide range of diameters and inner diameter sizes, so please feel free to consult with us. If you reach out, we can support you from one piece to mass production!

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.
