Abstract
An apparatus for abrasive tumbling or polishing with rotary-driven drums, mounted in a planetary rotational movement on two rotary-driven disks which face one another, the drums being mounted between the disks, the disks being supported by a fixed stand. The bearings in the carrousel disk on the feed-opening side of the drums being in contact with the perimeter of the drums. The disks are disposed at an angle to the vertical and have inclined walls.
Claims7
In a tumbling and polishing machine including several planetary rotating drums for processing the surfaces and edges of workpieces by means of abrasive bodies in the drums, said drums comprising rotatable, driven, front end loading drums, means for mounting said drums on a rotor comprising two axially spaced discs, means for rotating said discs about a rotor axis on a fixed frame, the improvement characterized in that the rotating axes of the drums are inclined in the direction of their upper ends towards the rotation axis of the rotor, and the rotation axis of the rotor is inclined from the vertical such that the axes of the drums in the lowest position at any given time is approximately vertical, and wherein the drums are provided at their lower ends with an openable base door for emptying the drums and are apertured for the outflow of treatment and rinsing fluids.
