Embodiment Construction
[0020] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.
[0021] Such as figure 1 As shown, the processing method of the half casing of the compressor of the aero-engine of the present embodiment comprises the following steps: a, the flatness of the longitudinal bonding surface of the two half half casings is processed, and the two half half casings after the rough machining The casing is plane-processed in the way that the datum plane is close to ensure the flatness of the longitudinal bonding surface of the two halves of the casing; b. The mutual position of the corresponding screw mounting holes on the longitudinal bonding surface of the two halves of the casing , finish machining at least part of the correspondingly set screw mounting holes, and place screws with positioning cylinders in the finished s...
