Brief Specialist Information For the designer in mechanical engineering and precision mechanics, but also for the interested professional buyer, knowledge of the physical relations involved in galvanization is of great use. Fig. 1: Setup of a Galvani…
With this material erosive, electrolytical process unevenness on the surface of the metal can be levelled out and sharp edges deburred;
Machined mechanical components, which have to be assembled under clean-room conditions must be free of surface impurities.
This process concerns about a replacement fort the transparent resp. yellow chromating.
Small series and/or individual parts for which an electroplating finish is not possible in automatic machinery or is too elaborate are processed on manually operated machineries in the Rohde factory in Göttingen, where there is equipment for bulk goods and also for individual processing of ”rack-items” available.
Even today, mechanical pre-treatment such as the above necessitates a high degree of manual work, depending on the articles and quantities involved; expertise is the most important prerequisite.
Blasting is one of the most important processes to produce even dull-finished or satin- finished surfaces before electroplating or anodizing. Here, glass-ball blasting with ball diameters of approx.
One of the most customary processes to deburr and/or precision-grind the surfaces of loose bulk items and machine components is vibratory grinding.
