生产实践证明，饼类锻件的生产难度要比轴类锻件大，因为饼类锻件在不同的变形工艺和参数条件下，有着差别极大的变形机制。大型饼类锻件常规生产的工艺存在着萌生裂纹源的变形机制，理论分析和实验证明，锥形板镦粗、局部压平的工艺是生产饼类锻件的最佳工艺，具有广阔的应用前景。 Production practice has proved that the difficulty of the production of cake forgings than the shaft forgings, because the cake forgings in different deformation processes and parameters under the conditions of a very different deformation mechanism. The deformation mechanism of the crack initiation source exists in the conventional production process for large cake forgings. Theoretical analysis and experiments show that the upsetting and partial flattening process of the cone plate is the best process for producing the cake forging, and has broad application prospects.
