Precise Mirror Polishing on Cylindrical Surface

TDC’s technics are capable of maintaining accuracy of size and shape at the same time as achieving nano level of surface roughness.
TDC realizes nano level surface roughness on many kind of materials stainless steel, nickel,glass, titanium, pure aluminum.

Why Super Precise Mirror Polish Surface Roll ?

Do you have problems with damage and noise on the surface of a printing roll before fine and precise patterning is applied?
Recent research and development of high-performance films have contributed to the development of finer patterns.
Finer patterns brought about a new problem ofincreased NGs, subtle damage or noise which used to be ignored are now frequently being unaccepted.
Although cylindrical grinding process also achieves mirror surface,it does not satisfy the requirement for a perfect surface without any damage and noise.
TDC developed a brand new machine in house which realizes a perfect surface without any damages, noises or frosted marks.
