Two tuning chamber shot blast machines were integrated into a existing manufacturing lines of a leading car manufacturer based in Southern Germany allowing the partial shot blasting of cylinder heads.
The cylinder heads are contaminated with metal shavings and residual sand from the casting process after a first machining process. This car manufacturer integrated two identical shot blast systems into existing manufacturing lines to remove both from the part surface. The equipment design had to be extremely compact, since space was very tight. Another requirement was the precisely defined surface area that had to be blasted, namely the combustion chamber side of the cylinder head. In addition, three bore holes and an existing matrix code had to be sheltered from the blast stream. Rösler offered the ideal solution with the compact turning chamber blast machine RWK 6/12-2 with an allowable work piece diameter of 600 mm (24”) and allowable height of 1,200 mm (48”). Each machine has two chambers so that the loading/unloading of a part can take place while another part is processed. Two Hurricane® turbines, type H 32, with 7.5 kW each provide the required blast intensity.
