1) First of all, before starting precision machining, we must choose a suitable CNC machine tool and write several economic and profitable plans for the machining process.
2) Then formulate a suitable CNC/mechanical processing plan for precision parts, analyze the drawings of the parts to be processed, perform parts on the processing content of the parts and adopt appropriate processing techniques.
3) Secondly, the choice of material hardness. For some occasions, the higher the hardness of the material, the better, but it is limited to the hardness requirements of the machined parts. The material is moderately soft and hard, at least a grade lower than the hardness of the machine parts. The basic one is that you must pay attention to the density of the material before processing.
4) Next, in the processing of high-precision parts, it is important to write and design the process flow. Because of the process steps of the part processing, the selection of benchmarks, the selection of processing tools, the selection and installation of fixtures, and the processing strategies and process parameters are determined. Affect the quality of the product.
5) Finally, in the process of high-precision parts processing, we must also pay attention to the full inspection of product quality before arranging shipments. If it does not meet the drawings, the secondary processing will meet the dimensions, accuracy, tolerances, technical parameters and other requirements of the drawings.
