Q36/Q76 shot blasting with automatic parts
handling For applications where residual stress values of 1,500 MPa are required R鰏ler developed a customer-specific peening system around the air blast system RSA 1400-S6. Here the parts are loaded automatically into the peening system with special handling systems which were also engineered by R鰏ler. However, if required, the system could also be loaded manually. The handling system removes one part (gear) at a time from a cleaning system and places it on the satellite fixture with an accuracy of +/- 1.0 mm. After the peening process the part is automatically removed and returned to the cleaning system. The system is equipped with three blast guns which direct the blast precisely to the areas to be peened. Up to three peening positions can be selected. Based on customer requirements the blast machines are equipped with one and two peening positions. At a blast time of 40 seconds this allows processing of 1,500 parts per machine in a three-shift operation (expansion up to 4,500 parts per machine is possible).
Extremely important was that the RSA system produces absolutely repeatable results. After the acquisition of the peening specialists Baiker and Vapor Blast R鰏ler has become the leading supplier of high-tech air blast systems for the automotive and aerospace industries. This technological leadership could be achieved – among other reasons -- with many patented solutions like, for example, special media dosing systems. A very important factor in achieving absolute repeatability of the peening results was the continuous media re-cycling and cleaning system consisting of air wash separator, screen decks and spiral separator. The latter ensures that only spherically shaped media remains in the system. Random shaped, broken media is discarded.
