After the general pressure vessel is welded and formed, no machining is required, and the special part of the large steam chamber is a workpiece with high precision. These dimensional accuracy, positional accuracy and surface roughness requirements are key requirements for large steam chambers and are prerequisites for their proper functioning, so the requirements must be met by the machining process. From the structure of the large steam room, its characteristics are: 1 Large size, the largest processing size reaches (φ5 200 ± 0.20) mm. 2 is a thin-walled piece with poor rigidity. In the machining industry, the size of the large-scale has increased the processing equipment and its accuracy requirements, (φ5 200 ± 0.20) mm dimensional accuracy of the processing has a certain degree of difficulty. At the same time, it is easy to produce the vibration knife, the knife, the force deformation, the heat deformation, the difficulty of detection and the deformation of the lifting, which directly affect the processing precision and surface quality of the workpiece. The workpiece after machining has residual stress, which causes problems such as deformation after processing and poor dimensional stability. The process problems of these processes and the technical problems after processing are likely to affect the normal use of large steam chambers.
