【Material】 General aluminum alloys, general copper, non-ferrous metals such as gold and silver, and resins such as acrylic. 【Features】 Our proud cutting technology has evolved further with our mirror surface cutting processing technology! (laughs) Previously, the mirror surface cutting processing achieved a surface roughness of about Ra 0.02 to 0.04, which is approximately 1/10 of the Ra 0.005 level realized by the lapping process representative of mirror surfaces. However! This time, by further improving our technology, we have achieved a surface roughness of less than Ra 0.01!! Furthermore, Nakata Seisakusho's mirror surface cutting technology does not use any impurities, making it suitable for devices in the semiconductor, LCD, biotechnology, medical, and food industries. On the other hand, for customers who have no issues with impurity contamination and simply desire mirror surface roughness, we can collaborate with polishing and lapping manufacturers to achieve ultimate flatness and surface roughness (nano-level precision)! For precision aluminum parts requiring mirror surface cutting, please contact Nakata Seisakusho.
