The production of hardware products is inseparable from CNC processing technology. The novices who are not familiar with the industry or are just beginning to know little about CNC processing technology. Shenzhen shengyuanda Hardware Products Co., Ltd. is committed to CNC processing of high-precision aluminum parts, which has strict requirements for processing procedures. How to reasonably arrange CNC processing sequence of high-precision aluminum parts in the operation of the author in this industry for many years What about it?
In the CNC processing workshop of aluminum parts, everyone has different working positions, but we must be familiar with and keep in mind the processing principles, such as the principle of first priority and then the secondary principle. What is the specific meaning?
Operators should first process the main working surface and assembly base surface of the parts, so as to find out the possible modern defects on the main surface of the blank as soon as possible. The secondary surface can be interleaved after the main machined surface is machined to a certain extent and before Zui final finishing.
Of course, there are certain rules in the processing of different aluminum parts, which need to follow the principle of surface first and then hole. The plane outline size of box and bracket parts is large, and the plane is generally processed first, and then the hole and other dimensions are processed. This arrangement of processing sequence, on the one hand, it is stable and reliable to use the processed plane for positioning; on the other hand, it is easy to process holes on the processed plane, and can improve the machining accuracy of holes, especially when drilling holes, the axis of holes is not easy to deviate.
Of course, the CNC machining process of high-precision aluminum parts should follow the principles of first coarse and then fine, first near and then far, and the principle of base surface first is not introduced here. In a word, after selecting CNC processing methods and dividing working procedures, the main content of the process route is to reasonably arrange these processing methods and the sequence of processing procedures. Only orderly processing can improve the processing quality and production efficiency of parts.
