What is rolling processing?
The special strength of cold rolling is that it allows for precise
rolling without oxidizing the metal surface!
We pass the metal foil through the cold-rolling mill again and again,
slightly reducing the space between the rollers each time.
To a thickness of only 0.001mm［1 micron］
（For reference, commercially-available aluminium foil has a thickness of 12 microns.）

While the structure is simple, the roller section
is extremely delicate
