Precision mechanics

Precision Engineering is a branch of engineering that deals with the production of precision mechanical components in devices. The small dimensions of these components are often due to the generally small external forces are also required to achieve high operating speeds with small masses and accuracy.

The mechanics developed from the manufacture of mechanical watches. This technique required precise machining of mechanical parts with high accuracy. Before increasing machine tools were used, files and scrapers were the main tools of precision mechanic with which mechanical processing with an accuracy of ± 0.05 mm was possible.

Since the devices were small and especially a high accuracy was required, the mechanical treatment has been developed as a branch of mechanics. For example, demand chronometers that were needed to navigate through the Merchant Shipping ( for determining longitude ) and the Navy, a high accuracy. Until the 1960s, these devices have a very high importance.

In the middle of the 20th century came to the two main fields of mechanics, optics and mechanics, as a third area of ​​the electronics which will increasingly displace the mechanics ( electronically controlled micro drives, micromechanical devices such as acceleration sensors and Hall ). With integration of electronic components, the term is often used here instead of Precision Engineering Precision Engineering.

Today, the precision engineering is a skill that is usually required to produce very precise scientific equipment.
