Optimization and Application of CNC Machining Process for Cross-hole Deburring in Aluminum Valve Shells

With the increasingly heavy manufacturing task of the valve in the rocket booster transportation system, the removal of the valve parts cross-hole burr urgently needs a stable and effective process method. In order to achieve a stable and effective removal to deal with cross-hole burr of Aluminum valve shells in carrier rockets, a CNC deburring process to remove cross-hole burr by deburring-tool is presented in this paper. The study scheme for cross-hole in Aluminum valve shells is designed to study machining principle of cross-hole chip removal process. The influence rule of machining quality on conditions of different cutting parameters is analyzed. The optimal parameters for cross-hole deburring are obtained. The study results show that deburring-tool can form edge blend in position of intersecting line within the cross-hole, and the stable and efficient deburring process of cross-hole in Aluminum valve shells is realized. This CNC deburring process achieves good results in application of cross-hole deburring in Aluminum valve shells. Good machining effect has been achieved in the application of aerospace valve products.
