About三井精機工業

Contributing to the industrial sector through machine tools that support cutting-edge technologies around the world and compressors that are active in various industrial fields.

Mitsui Seiki Co., Ltd. was established in 1928 (Showa 3) with the aim of producing precision measuring instruments and precision machine tools, which were then dependent on foreign imports, domestically. The company is composed of two divisions: "machine tools" and "compressors," and has earned a high reputation in the industry as "the technology of Mitsui Seiki" by developing high-performance products in each division. We will further realize our management philosophy of "contributing to society by supplying machine tools as mother machines that are the backbone of industry and air compressors as power sources to the industrial sector" at an even higher level.
