Abstract: System for processing technical surfaces, in particular surfaces of essentially rotationally symmetrical work pieces (3), comprising at least one processing unit (4) and one motor-driven work-piece carrier (1) and, mounted thereon in rotatable fashion, at least two or more holders (5) that feed work pieces (3) to the processing unit (4), characterized in that the processing unit (4) includes means (6) serving to exert an essentially constant hold-down pressure on the surface of the respective work piece (3), while the motor drive is so designed as to control the feed-in-timing sequence of the work pieces (3) and the duration of their processing cycle in the processing unit (4).

Abstract: A coating is stripped off a work piece by applying a chromous and aluminiforous coat directly on the work piece and stripping the work piece with an alkaline solution containing a strong oxidant. A single-compartment system can be used, which includes a spray chamber including a circulatory spray-cycle system; a support for holding the work piece; and a media container connected to the spray chamber via a media circulation system.
