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

Due to the large amount of drilling during rough machining, the cutting speed and clamping force of the product workpiece are large, and the calorific value is large. Stress, if roughing and roughing continue, the precision of the finished part will be quickly lost due to the re-distribution of internal stress. For some parts with high machining precision standards. After roughing and before finishing, an ultra-low temperature quenching or tempering treatment step should also be assigned to remove thermal stress.

(2) Effective use of aluminum alloy cnc processing machinery and equipment

Rough machining mainly removes most of the machining capacity, and does not require high machining precision. Therefore, rough machining should be carried out on equipment with relatively large output power and low precision, while the finishing process requires relatively high machining accuracy. High-precision CNC lathe processing. Roughing and finishing are processed on different equipment, which can not only give full play to the working ability of machinery and equipment, but also increase the service life of precision CNC lathes.

(3) In the aluminum alloy cnc processing process line, the heat treatment process is often assigned

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