Verfahren zur thermischen Behandlung von mikromechanischen Bauteilen von Uhren

摘要

The process comprises heating a part of a micromechanical horological component at a temperature of 200[deg] C for a short period of time to increase its hardness by local phase modification so that the heated part is affected by the thermal treatment and the untreated part remains unchanged. The process of increasing the hardness of the component is carried out by a laser beam, an induction heating system, or an element, which heats the component by direct contact with radiation. The component is placed on a fitting in which heat is introduced.
