Precision parts machining is precision machining for precision parts of precision equipment. The precision requirements are very high. This also leads us to not only understand the specific requirements of materials for parts machining 6061 aluminum, and the common skills of machining parts, but also understand precision What are the stages in the process of machining precision parts? Below, the PTJ operator will share with you the 5 stages of precision mechanical parts machining.

  • 1. Roughing
    Mainly to increase productivity. Cut off the machining allowance of the machined surface, and machine a fine datum.
    2. Semi-finishing
    It is mainly to remove the defects that may occur after rough machining, and to complete the machining of the secondary surface. A certain degree of machining 6061 aluminum accuracy must be achieved in order to prepare for the finishing stage and ensure proper finishing allowance.
    3. Finishing
    In the finishing stage, the parts processed by precision parts mainly adopt high cutting speed, small feed rate and cutting depth to remove the machining allowance left by semi-finishing, so that the surface of precision mechanical parts meets the technical requirements of the drawings.
    4. Finishing
    Mainly used to reduce the surface roughness or strengthen the processed surface, mainly used for surface machining with high surface roughness requirements.
    5. Ultra-precision machining
    Mainly use precision cutting, precision mirror grinding, precision grinding and polishing to make the workpiece machining accuracy within 0.1-0.01μm, surface roughness value ra≤0.001μm.

to sum up
The five stages of precision parts machining 6061 aluminum are from coarse to fine, gradually increasing precision. After these five stages of machining, the accuracy of mechanical parts can meet the requirements of customers.
