Company information
Our company was founded in 1951 in Kobana, Kawanishi City, Hyogo Prefecture, with the aim of precision machining of small parts using Swiss-made small precision automatic lathes as the core. Currently, we operate with a four-factory system in Osaka and Hyogo Prefectures. At the time of our founding, we specialized in parts machining, but since the machining equipment necessary for parts processing was predominantly foreign-made and very expensive, we decided to develop our own cam-type automatic lathe, which led to the birth of our precision division. We also manufacture cutting tools in-house, creating unique strengths that extend beyond parts machining to include tool design and the use of our own dedicated machines. We have two divisions: the machine tool division and the parts division. In the "Parts Division," we perform high-precision and complex precision machining using our unique machining and management technologies, ensuring that we can meet a wide range of customer requests from prototyping to mass production under a highly reliable quality assurance system. In the "Machine Tool Division," we design machine tools and utilize a super finishing machine called the "Super Finisher" using a film method, widely accommodating ultra-fine machining of parts that require high performance and high efficiency, from standard machines to dedicated machines.
