Precise Mirror Polish Surface on Roll and Shaft

What is super precise mirror polished rolls and shafts

TDC’s super precise mirror polished rolls and shafts

Precise Mirror Polish Surface on Roll and Shaft

TDC technology achieves nano-level surface roughness without defects, fogging, and distortion while maintaining dimensional and shape accuracy. It dedicates to higher precision of molds for nano imprint and high-performance film manufacturing.
In addition to stainless steel, nickel, glass. titanium and pure aluminum can also be processed.

High-precision mirror rolls are essential when manufacturing high-performance films such as wearable devices that measure electrocardiographic and blood glucose levels and electronic devices such as RF tags.

It is also used in scenes that require panel processing with less fogging and reflection, such as the recent coronavirus infection prevention sheet and face shield.

Why TDC is the best for mirror-polished rolls/shafts?

  • Applicable to Nanoimprints and high function films
  • Polishing cylinders completely eliminating scratches and frosts

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 of increased 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.
