Aluminium-component, clean pickled
Machined mechanical components, which have to be assembled under clean-room conditions must be free of surface impurities.
For example, the aluminium elements for the laser industry shown here are cleaned in a 17-stage degreasing and pickling process (partly automatic, partly manual) to meet these extreme demands. The plant specially developed for this purpose was necessary to attain perfect results even in hollow chambers and blind bore holes. The material abrasion entailed here amounts to approx. 20-50 µm and need only be taken into account at fine screw threads.
