Super Precision Long Foil Polishing

Workpieces over 100 meters in length
Realize roughness in nano-level

What is Super Precision Foil Polishing?

TDC developed a polishing system for polishing foils achieving Nano surface with 100M length.

Why Super Precision Foil Polishing?

Precisions

Ra1 nm, Rz6 nm
Low cost

This foil will help you simply your post-step process and realize a cost down.
Handy

by polishing the foil continuously, we can provide a mirror polished foil in the length you desire.
Usage

device processes for Roll to Roll, Fine film deposition process, and others.

Specification

TDC developed a special machine specifically for long foils.
It continuously supplies foil to the lapping machine　for polishing.
After the polishing, it automatically rolls them up again.
