Is it difficult to process precision parts made of aluminum? Factory masters with more than ten years of processing experience to teach you! ! !

In the aerospace, automotive and mechanical fields, precision machining of aluminum parts is becoming more and more widely used. Due to the high machinability of its raw materials, the dimensional accuracy of the corresponding parts and the surface roughness of the parts are very demanding in the above-mentioned fields. high.

  Plastic processing for precision machining of aluminum parts must ensure stable product output and quality, consistent required dimensional accuracy, mechanical properties and good surface quality. Also pay attention to prevent cutting fluid corrosion and mechanical damage, control grain size and organizational structure, these quality requirements are mainly guaranteed by production processes and equipment. Aluminum and its alloys generally have good plasticity and are easy to process plastically.

  The phase composition in the precision machining of hard aluminum parts is relatively complex, and there are brittle structures such as low-melting phase and intermetallic compounds. Its plastic processing has some characteristics: such as homogenization treatment to eliminate the internal stress and intragranular generated during billet cooling Segregation; the surface of the billet must be milled to remove the surface segregation generated by the low-melt phase. Some aluminum alloys need to be clad with aluminum to improve corrosion resistance and workability. Aluminum alloys have overheating sensitivity during precision machining of aluminum parts, and the heating temperature must be strictly controlled.
