• Processing Contract

The ultra-fine processing technology held by Hashikawa Manufacturing Co., Ltd. is a wire-cut super finishing technology that meets sub-micron precision. It is also capable of satisfying the required precision of 0 to -0.00005mm for optical fiber ferrule molds. While there are limitations on material and plate thickness, it is possible to achieve pseudo-mirror finishing. This ultra-fine processing technology, which uses discharge machining as its core technology, enables the realization of high value-added manufacturing.
