Differences in processing technology for shaft parts with different materials and performance requirements of metal shafts

‌Carburized steel shaft‌: material preparation → forging → normalizing → drilling center hole → rough turning → semi-finishing turning, finishing turning → carburizing → quenching, low temperature tempering → rough grinding → secondary surface processing → finishing grinding.
‌Quenched and tempered steel shaft‌: material preparation → forging → normalizing (annealing) → drilling center hole → rough turning → quenching and tempering → semi-finishing turning, finishing turning → surface quenching and tempering → rough grinding → secondary surface processing → finishing grinding.
‌Precision nitrided steel shaft‌: material preparation → forging → normalizing (annealing) → drilling center hole → rough turning → quenching and tempering → low temperature aging → rough grinding → nitriding → secondary surface processing → finishing grinding → polishing.
Overall quenching shaft: material preparation → forging → normalizing (annealing) → drilling center hole → rough turning → quenching and tempering → semi-finishing turning, finishing turning → overall quenching → low-temperature aging → fine grinding.
