Key points of aluminum alloy shell processing

In order to ensure the machining accuracy of aluminum alloy shell, rough and finish machining should be carried out separately. Because during rough machining, the cutting amount is large, the cutting force and clamping force of the workpiece are large, the calorific value is high, and there is a significant work hardening phenomenon on the machined surface. There is a large internal stress in the workpiece. If the rough machining and rough machining are carried out continuously, the precision of the parts after finishing will be lost quickly because of the redistribution of stress. For some parts that require high machining accuracy. After rough machining and before finishing machining, low-temperature annealing or aging treatment procedures should also be arranged to eliminate internal stress.
Reasonably select aluminum alloy shell processing equipment. Rough machining is mainly to cut off most of the machining allowance and does not require high machining accuracy. Therefore, rough machining should be carried out on machine tools with high power and low accuracy, while finishing process requires high-precision machine tools. Rough and finish machining are processed on different machine tools, which can not only give full play to the equipment capacity, but also extend the service life of precision machine tools.
