Adamant Namiki's Fine Hole Processing technology has evolved from micron to nano level order. Femtosecond laser and diamond micro drill makes this possible.
A metal drill is inadequate for making tiny caliber hole. But by using a femtosecond laser and a diamond micro drill, tiny caliber and multi-hole processing becomes possible.
Moreover, high aspect ratio holes can also be made.
With femtosecond laser processing, minute holes do not have to be pierced from only one direction, but can be made vertical, horizontal, and slanted, and can also be made in various figurations such as a Y-shape.
