Since the early 1930s, demand for mass-produced machine tools has increased in Japan with the development of the aircraft and automobile industries. Bat, the domestic technology of machine tools was immature, and most of the precision machines and press machines were imported products. However, it is also a fact that some private companies have been moving to promote domestic production in anticipation of the future. For example, Kiichiro Toyoda, the founder of Toyota Motor Corporation, ordered and introduced various machines from domestic manufacturers at the same time as the construction of a new factory in 1937. This time, one of them, a 40T press machine manufactured by Aida Iron Works was disassembled and investigated. At that time, Japan was at the stage of imitating machine tools made in the US, and the quality of iron was inferior to that of the US. Therefore, instead of simply imitating, we can see some ingenuity in how to make a good machine after understanding Japan's technological capabilities. It can be said that the domestic press machines at that time were in the stage of searching for the "independence period" from the "imitation period".
