History of the Development of the Milling Chuck

With the introduction of the Nikken milling chuck in 1983, the straight shank end mill was developed, contributing to the development of industry not only in Japan but worldwide. (The pull-screw Morse taper end mills that common at the time were difficult to use.) Since then, the Nikken milling chuck has benefited numerous improvements and innovations. It's no exaggeration to say that the development of the milling chuck is the history of Nikken!
