Machine processing of step shaft

Surface treatment of stepped shaft
  1. Introduction to step shaft
    Step shaft is a shaft with multiple cylinders with different diameters connected together like steps. The turning of the stepped shaft is actually a combination of outer circle and plane turning. We must therefore take into account the dimensional accuracy is required and the length of the outer circumference of the step in turning.
    The technical requirements of step shaft:
    1. The coaxiality between the outer circles of eaach gear.
    2. The perpendicularity between the outer circle and the step plane
    3. The flatness of the step plane
    4. Clear corners at the intersection of the steps of the outer circle
    2. Production capacity
    CNC lathe processing: Φ5mm-Φ60mm * 700mm
    CNC milling machine processing: 800mm * 1500mm * 700mm
