1. Reduce deformation
Reduce the influence of processing stress on aluminum alloy deformation. Heat treatment after rough machining can greatly reduce the influence of stress on finish machining.
2. Improve accuracy
Improve the accuracy and surface quality of aluminum profile machined parts. After heat treatment, finish machining is carried out. Because finish machining improves the machining accuracy on the basis of rough machining, the machining amount is relatively small, and the resulting deformation stress is also very small, so it can greatly improve the quality of aluminum profile machined parts.
3. Improve production efficiency.
As long as enough machining allowance is reserved for finishing in rough machining, there is no need to consider the problem of dimensional tolerance too much. It can effectively improve the processing efficiency of various machine tools.
