What are the difficulties and tricks of NC machining of aluminum alloy shell parts?
With the increasing application range of aluminum alloy shell parts, its processing quality and efficiency have become the topic of increasing concern of processing manufacturers.
In order to ensure the quality and efficiency of numerical control machining, it is necessary to study the numerical control machining technology of aluminum alloy shell parts, and put forward the principle of determining the machining process route, the key points of selection and the method of designing numerical control machining technology in the process of numerical control machining, so as to ensure the machining quality and improve the productivity.
Aluminum alloy shell parts have an important effect on the performance of equipment. They all have complex appearance, inner cavity, strict tolerance of size and shape position, thin wall and uneven wall thickness, easy to deformation. With the development of material science and the progress of processing technology, the requirements of aluminum alloy shell parts are increasingly high, to improve the quality of products, shorten the production cycle, must use CNC equipment for comprehensive processing, and determine the optimization of CNC processing technology.
Shell parts in rough machining, cut out the metal layer is thicker, the cutting force and clamping force are relatively large, the cutting temperature is relatively high, will cause large deformation. Machining according to machining stage, machining errors caused by rough machining can be corrected by semi-finishing machining and finishing machining, so as to ensure the machining quality of parts. At the same time, rational use of equipment can not only improve productivity, but also prolong the service life of precision equipment.
