machining characteristics of aluminum alloy parts machining
The aluminum alloy part machining process can separate the rough and finish machining. After the rough machining is completed, the parts are heat treated, the part's cutting stress and residual stress are fully released, and then the finishing machining is performed. (NOBLE smart manufacturing technology) The machining quality of the parts will be greatly affected. To improve and implement coarse and fine machining separately has the following advantages:
(1) It can reduce the effect of residual stress on machining distortion. After the roughing is completed, it is recommended that heat treatment be used to remove the stress caused by the roughing of the part, which can reduce the influence of stress on the quality of the finishing process.
(2) Improve machining accuracy and surface quality. After the rough and finish machining are separated, the finishing machining is only machining a small margin, resulting in a smaller machining stress and deformation, and can greatly improve the quality of the parts.
(3) Improve production efficiency. Since rough machining removes only excess material and leaves a sufficient margin for finishing, it does not take into account size and tolerances, effectively exerting the performance of different types of machine tools and improving cutting efficiency. After the aluminum alloy parts are machined, the metal structure in the machining table will undergo great changes. In addition, the effect of cutting movement will lead to a large residual stress. In order to reduce the deformation of the parts, the residual stress of the material needs to be reduced and released fully.
