Here we introduce the Cincom Miyano Automatic Lathe Museum at Citizen Machinery's Karuizawa Headquarters.
This museum communicates the passion of the engineers by tracing the evolution of the automatic lathe.
Swiss type automatic latheAutomatic Machine No.1
This belt-driven, 4 tool, automatic lathe was made by Joseph Petermann Ltd of Switzerland. In 1923 Kuwana Seiko Co., Ltd purchased 5 units for 10,000 yen (to put this in perspective admission to the theatre cost 30 sen and 1 yen = 100 sen). The lathe was driven by a water wheel and was used to produce the small diameter screws used in watch repairs and then later to produce blank pinions until the 1980’s. During WWII the maker's logo was removed.

Boley was founded by Gustav Adolf Boley; having worked for a few years as an apprentice in a watch shop in Germany, he established a trading company for watch parts in Switzerland. In 1870 he started the company Boley in his home town of Esslingen, near Stuttgart. Initially Boley manufactured tooling and machinery for watch production as well as repairing watches directly. The company began to focus on industrial machinery when they developed a table lathe with a collet chuck and a small milling machine in 1875 and 1882 respectively; this trend was secured in 1885 when they obtained a patent for the turret lathe they had developed.
The machines and tools manufactured by Boley were highly praised and Boley became recognised not only as a manufacturer of watch making machinery but as a producer of precision machinery. In 1992 Boley became a part of the Citizen group and now contributes to Cincom/Miyano sales for the European region.
