Company PR
Since our establishment in 1973, we have been taking advantage of a high level of technology in the field of metalworking, particularly in precision cutting, and we have been involved in the manufacture of various machine parts. During this period we have made an active effort to introduce the latest machining technologies and processing machines, and we succeeded in realizing cutting technology for difficult-to-cut materials and other metal materials, and machining technology for manufacturing free-form surface parts by using simultaneous multi-axis machining driven by three dimensional CAD and CAM. We are now able to meet many customer expectations due to a high standard in parts machining, by combining advanced machining technologies with traditional craftsmanship skills. We hope that we are able to play a part in realizing a rich society by responding to customers' expectations by further improving quality , skill and technology.
