Precision engineering at its best

 

The Black Forest was already known for its clocks in the eighteenth century. At that time, these were made on the farms and sold by the clock carriers at markets in different parts of the world. In the nineteenth century, the production of clocks shifted more and more to factories established for this purpose, such as those in Triberg, St. Georgen or Schramberg. They also changed the method of production. Until then, the farmers had primarily used wood as a material, but industrial production now used metal. In addition, from now on, highly specialized timekeepers such as alarm clocks or control clocks were also developed.

However, there were some companies in the Black Forest, especially in St. Georgen, that already in the nineteenth century produced simple lathes and sold them to the clock-makers on the farms. These companies were initially blacksmiths, which subsequently grew steadily. In the beginning, in addition to the lathes, they also manufactured other components for the clocks, so they were a link in the division of labor in clock-making in the Black Forest.

Thanks to the lathe, the individual parts of the clocks could be worked on more quickly and easily by the farmers. The principle of this tool is to clamp a component in such a way that it is fixed but can be rotated around its own axis. Thus, it is possible to machine the workpiece from different sides and even rotate it while it is being machined. In addition, clamping leaves both hands free, allowing for more accurate tool guidance. The use of a lathe, provided that the clamped workpiece is one made of metal, is also called "metal cutting".

The former blacksmiths mentioned above grew in the course to become specialists in lathes, which they manufactured not only for clock-making, but also for other fields. They built milling machines and industrial tools. Based on this orientation, in the twentieth century other companies in the field of precision engineering were established, specifically dedicated to the field of consumer electronics, especially in St. Georgen and Villingen. Brands such as Dual, PE and SABA are well known, although they no longer exist. These companies manufactured record players, cassette recorders and tape recorders. Today, the German Phonomuseum in St. Georgen is a reminder of that era.

There is also the Hotel Federwerk in St. Georgen, which is set up in a former factory building and brings the industrial history of the place to life. Each room is dedicated in its design to a company or a technical innovation. Thus, the house contains a total of 51 different episodes about the inventors of the city.
