Precision mechanics
Precision mechanics is a branch of technology that deals with the manufacture of precision mechanical components in devices. The small dimensions of these components are often due to the generally small external forces, but are also required in order to achieve high working speeds and accuracies with small masses.
Precision mechanics developed from the manufacture of mechanical watches . This technique required precise machining of mechanical parts with high accuracy. Before machine tools were increasingly used, files and scrapers were the main tools of the precision mechanic, with which mechanical processing with an accuracy of ± 0.05 mm was possible.
Since the devices became smaller and, above all, high accuracy was required, mechanical processing was developed as a branch of mechanics . Chronometers , for example , which were required for navigation in merchant shipping (to determine the degree of longitude ) and in the navy, require a high degree of accuracy. Until the 1960s, these devices were very important.
In the middle of the 20th century, electronics were added to the two main areas of precision mechanics, optics and mechanics, as a third area , which is increasingly displacing mechanics (electronically controlled fine drives, micromechanical components such as acceleration sensors). When including electronic components, the term precision engineering or device technology is often used here instead of precision mechanics . In this context, there is also the apprenticeship as a precision mechanic , in which precision mechanics can be chosen as a focus.
Today precision mechanics is a skill that is mostly needed to manufacture very accurate scientific devices.
