截止到1996年5月,日本三菱电机公司的电火花机床产量,累计突破3万台。一个企业的电火花机床的生产超过3万台,这在世界上还是首次。 三菱电机是从1964年开始生产电火花机床的,它的主导产品是重电机,拥有优良的电气应用技术、加工装配技术及大批量生产技术。该公司于1952年开始在其中央研究所着手电火花机床的研究开发,并在1957年完成了高频重迭电容式电火花机床的生产。当时,电源系统由三菱电机负责,主机由三菱重工业制造。
As of May 1996, Mitsubishi Electric Corporation’s EDM production exceeded 30,000 units. A company’s EDM machine production exceeds 30,000 units, which is the first time in the world. Mitsubishi Electric has been producing electric discharge machine tools since 1964. Its leading product is heavy electric motors, and it has excellent electrical application technology, processing and assembly technology, and mass production technology. The company started research and development of EDM machines at its Central Research Institute in 1952, and completed the production of high-frequency overlapped EDM machines in 1957. At that time, Mitsubishi Electric was responsible for the power system, and the host was manufactured by Mitsubishi Heavy Industries.
