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).
Claims8
System for processing technical surfaces and in particular the surfaces of essentially rotationally symmetrical work pieces (3), encompassing 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 work pieces (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).
System as in one of the preceding claims, characterized in that the means (6) include at least one gas-pressure-operated damper, spring elements, elastic elements or weights and, if necessary, lever elements.
System as in one of the preceding claims, characterized in that the work-piece carrier (1) is disk- or belt-shaped.
System as in one of the preceding claims, characterized in that the motor drive is a continuous, cyclical or stepped feed drive.
System as in one of the preceding claims, characterized in that the holders (5) can be rotated by the tangential force of the processing unit (4) bearing on the circumference of the work pieces (3).
System as in one of the preceding claims, characterized in that the holders (5) can be rotated by separate drive mechanisms.
System as in one of the preceding claims, characterized in that the drive mechanisms include a gear wheel and crown gear ring, a friction wheel and friction ring or the like.
