Abstract: In order to improve the weakness that for the processing method of the traditional thin walled parts, the processing precision cannot be guaranteed and the productivity is low, aiming at the special purpose of the typical thin walled parts within turbine combustor, the structure and material of the thin walled parts were analyzed. The processing, processing craft, processing program and detection on important surfaces were summarized and the problems required to be noticed during processing preparation, fixing scheme, rough machining and finish machining were emphatically analyzed. A qualified and efficient processing method in accordance with the production practices was proposed, and the VMC (vertical machining centre) KVC800 and numerical control process technology were utilized to solve the difficulties during the processing. The research result shows that, for the thin walled parts with complex structure, thin wall, multiple surface curves and high demand on precision, the numerical control processing method cannot only be used to produce satisfactory parts, but also to reduce the processing procedure and improve the qualities of the parts. It will be of availability and effectiveness if it is applied in practical production.
