All relevant process parameters such as quantities of shot media, blasting pressure and movement of jet nozzles and workpiece can be programmed as desired over a wide range and replicated within very narrow tolerances. These are important requirements for a predictable and well-controlled peening process.
Peening with metal, glass or ceramic shot can compact or densify the area next to the surface. This prevents cracks from forming and increases solidity and longlastingness.
The comprehensive Roxor tool set can process even the most complex workpieces in one go with individualized peening parameters for outside and inside contours. Completely automatic change of tools further enables reference positions on the workpiece to be determined in the μm range.
The surface of thin-walled workpieces can be peened with a fairly large size of shot, which causes a deformation. In contrast with deep-drawing, workpieces of varying degrees of strength (thickness) can be shaped in a very precise manner.
The Roxor peening module enables uniform treatment of the whole surface, or just a partial finishing treatment.
With the use of two peening modules, the workpiece can, where required, be peened with two different kinds of shot at the same time.
Corundum or edged shot can be used to roughen a bearing surface. Known as “activation”, this preliminary treatment is typically used in galvanic treatment of surfaces, to increase their adhesiveness.
The precision of Roxor shot dosage enables uniform roughening of the workpiece surface without much loss of material.
Roxor peening machines are further designed to save time when changing the type of shot used.
With edged shot media, an unwanted layer (whether lacquer or dirt) can be broken up and removed.
The precision of Roxor shot-media dosage ensures complete removal of the unwanted layer, without loss of material from the layer underneath. During the peening process and the insertion and removal of the workpiece, no shot material escapes into the environment.
