Alumina ceramic components / relay ceramic assemblies / ceramic - metal brazed contactor
1. Description:
The present paper deals with an effective and alternative adjustment method for precise alignments of components of precision engineering and optics—the so-called method of stepped transfer of momentum bases on measured stroke impulses, which act onto a pre-stressed object and effect stepwise movements. The strokes are generated and applied to the components in several directions by special electromechanical hammers by means of a PC software and a measurement device. The automatic operation is finished if the target position of the object is attained. Achieved adjustment accuracies for the fixed components may be in the sub-micron range. The paper discusses theory and experiment of motion behavior of pushed components under the influence of applied momentum, pre-stressing and frictional forces. Additionally, it describes the wide application range of this adjustment method on the basis of developed prototypes.
