All kinds of CNC processing and customization manufacturers are innovating and improving the processing technology of shaft Machine element. For the processing of shaft parts, we should not only understand the processing procedures of large machining plants and the production safety requirements of large machining plants, but also understand the processing process requirements. What are the processing process requirements for axial Machine element?
1. Dimensional accuracy
The journal is the main component of shaft parts, which affects the rotational accuracy and working state of the shaft. The diameter accuracy of the journal is usually IT6-9 according to its usage requirements, and the journal accuracy can reach IT5.
2. Geometric shape accuracy
The accuracy of the geometric shape of the journal (roundness, cylindricity) should generally be limited to the tolerance points of the diameter. For those with high requirements for geometric shape accuracy, allowable tolerances can be specified separately on the part drawing.
3. Positioning accuracy
Refers to the coaxiality of the mating journal of the assembled transmission parts relative to the supporting journal of the assembled bearing, expressed as the radial circular runout from the mating journal to the supporting journal; According to usage requirements, high-precision shafts are 0.001~0.005mm, and general precision shafts are 0.01~0.03mm. In addition, the coaxiality of the inner cylinder and the verticality of the axial positioning end face to the axis are also required.
