1. First of all, after receiving the processing requirements of customers’ drawings, before starting precision machining, we should select appropriate CNC machine tools and prepare several sets of economic and effective schemes for machining processes. The appearance with high machining quality requirements is divided into machining stages, which can generally be divided into three stages: rough machining, semi finishing and finishing. Mainly to ensure the processing quality. Conducive to scientific application of equipment. Facilitate the arrangement of heat treatment process. As well as facilitate the discovery of blank defects, etc.
2. Then formulate the appropriate machining scheme of CNC machining of precision parts, analyze the drawings of the parts to be machined, analyze the machining contents of the parts, and adopt the appropriate machining technology.
3. Secondly, for the selection of material hardness, for some occasions, the higher the hardness of the material, the better. It is only limited to the hardness requirements of the processing machine parts. The material is moderate in soft and hard, at least one grade lower than the hardness of the machine parts. Therefore, the most basic thing is to pay attention to the density of the material before processing.
4. Then, in high-precision parts processing, it is important to compile and design the process flow, because the program steps of parts processing, the selection of datum, the selection of processing tools, the selection and installation of fixtures, and the determination of processing strategies and process parameters affect the quality of products.
5. Finally, in the process of high-precision parts processing, we should also pay attention to the full inspection of product quality before arranging shipment. If it does not comply with the drawing, it will be processed again to meet the requirements of drawing size, accuracy, tolerance, technical parameters, etc. Junying is equipped with complete precision machining equipment, CNC machine tools and testing equipment. It has more than ten years of precision machining experience and strict control over product quality, which can provide worry-saving and labor-saving one-stop service.
