Step shaft is one of the most frequently used basic parts in machinery and equipment, and it is also the most critical part. Its function is mainly to support in the machine, connect the parts that play a role of transmission, and maintain the inertia of movement to maintain the continuous operation of the machine. Stepped shaft is the most important part of shaft parts. In actual processing, the processed parts always fail to reach the design goals. In order to ensure that the processing technology meets the requirements of machine equipment, Minghe formulated the process regulations Standards are strictly reviewed. Minghe specializes in precision machining long, cylindrical components. Our 30+ years of experience in CNC turning bar stock have allowed us to optimize the production of large quantities of custom Step shaft. All of our metal and plastic pins are manufactured following the highest industry standards, making our processes suitable for military, defense, aerospace, automotive, electronic, and medical applications.
1. Product introduction
A stepped shaft is a shaft with multiple cylinders with different diameters connected together like steps. The turning of a stepped shaft is actually a combination of outer circle and plane turning. Therefore, the dimensional accuracy and step of the outer circle must be taken into account when turning. Length requirements. The technical requirements of the stepped shaft:
- The coaxiality between the outer circles of each gear.
- The perpendicularity between the outer circle and the step plane
- The flatness of the step plane
- Clear corners at the intersection of the steps of the outer circle
