What are the standards for aluminum alloy CNC machining process?

(1) In order to ensure the precision of CNC machining of aluminum alloy, rough and finish machining should be carried out separately

During rough machining, the drilling volume is large, the cutting speed and clamping force of the product workpiece are large, the heat value is large, and the surface of the product workpiece has a relatively obvious processing hard bottom. The internal structure of the product workpiece has a large thermal stress. If the rough and rough machining continue to be carried out, the precision of the finished part will be rapidly lost due to the re spread of the internal stress. For some parts with high processing precision standards. After the rough machining and before the finish machining, the ultra-low temperature quenching or quenching and tempering treatment steps should also be allocated to remove the thermal stress.

(2) Effective use of aluminum alloy CNC processing equipment

Rough machining mainly cuts off most of the machining capacity and does not require high machining precision. Therefore, rough machining should be carried out on equipment with high output power and low precision. The process flow of finish machining requires high-precision CNC lathe. Rough and finish machining are processed on different equipment, which can not only give play to the working capacity of machine equipment, but also increase the service life of precision CNC lathe.

(3) Heat treatment process flow is often distributed in the process line of aluminum alloy CNC processing

The plan of the process parts of the heat treatment process is as follows: in order to improve the drilling processing characteristics of metal materials, such as quenching, normalizing and aging treatment, they are generally arranged before the machining of mechanical equipment. In order to remove thermal stress, such as quenching and tempering treatment and heat treatment, they are generally arranged after rough machining and before finishing machining. In order to better improve the physical properties of parts, such as nitriding, heat treatment and quenching, they are generally arranged after the machining of mechanical equipment.

If there is great deformation after the heat treatment process, Zui final processing process flow shall be allocated. Proper operation method and maintenance is one of the main factors for rational application of aluminum alloy CNC machining equipment. The application of reasonable operation method can avoid abnormal damage of CNC lathe and prevent common failures; Daily maintenance: maintain stable process conditions of machines and equipment, slow down the deterioration process, timely handle and solve common faults and hidden dangers, and always ensure safe operation.
