Tumble machines
Type CUBESTA®
Rubber belt tumble machines
These machines are suitable for the automatic shotblasting of tumble-proof casted, forged, stamped and flame-cut parts in batch operation as well as for the surface hardening of springs.
The tumble belt is made of perforated rubber with supporting tissue. Depending on the model, it is suitable for load weights up to 20 or 30 kg.
The parts are either loaded manually or with a hydraulic tilting device out of a transport container onto the belt and are continuously circulated during the blasting process. After the blasting, the discharge of the workpieces takes place by a changeover of the conveying direction of the tumble belt. In that case, the workpieces are dropped onto an additional discharge belt, a vibrating conveyor channel or also directly into an underneath transport container.
Steel belt tumble machines
These machines are suitable for the automatic shotblasting of tumble-proof casted, forged, stamped and flame-ut parts in batch operation.
The tumble belt consists of high wear resistant manganese hard steel plates and cast chain links. Depending on the model, it is suitable for load weights up to 125 or 200 kg.
The parts are loaded from a transport container onto the belt by means of a hydraulic tilting device and are continuously circulated during the blasting process. After the blasting, the discharge of the workpieces takes place by a changeover of the conveying direction of the tumble belt. In that case, the workpieces are dropped onto an additional discharge belt, a vibrating conveyor channel or also directly into an underneath transport container.
