ナノテク研磨

東京ステンレス研磨興業のナノ研磨は、金属表面を鏡面状態に仕上げRaを数nmに抑える技術で、従来の鏡面=意匠性と言う概念ではなく、その機能性が大手企業や研究機関に注目され用途開発が進んでいます。

なかでも、チタンの研磨は、チタンウエハやMEMSデバイスシステム開発に協力しており、医療分野でのMEMS開発、電子工学等での適用も進んでいます。

光学顕微鏡でしか確認できないレベルの超精密な仕上がりを当社独自の技術が実現し、今後希少金属の代替分野や液晶の大型化への対応をはじめと して未知の分野への参入が期待されております。

研磨粗さデータ

ステンレス(SUS304) = 1.5nm (Ra)
チタニウム(Gr-1) = 5-6nm (Ra)
アルミニウム(Pure Al) = 4-5nm (Ra)

Synopsis: Various techniques for polishing of titanium such as mechanical, chemical, electrolytic and electrolytic-abrasive polishing and so on have been outlined.
Recently the titanium sheet with the average surface roughness (Ra) of nanometer-order has been obtained by using the mechanical and the electrolytic-abrasive polishing processes with comparative ease. The mirror polished titanium has served various uses from the artistic production to the high technology field e.g. as MEMS devices. In case of complex parts as the dental and the medical treatments, the electrolytic polishing is preferably applied.
It is important that the polishing technique should be selected with the shape and size of the work.
