How to judge the quality of spinning products?
CNCspinning processingIt is a metal processing method that has gradually entered people's field of vision in recent years. Compared with the common hardware processing technology such as turning, milling, stamping and other processes are very different. Due to the lack of understanding of the CNC spinning process, many customers do not know how to judge the quality of CNC spinning products from what angle. Let me introduce you in detail from several aspects.
Diameter accuracy of 1. spinning products
From the product diameter accuracy, the accuracy of CNC spinning products is not up to CNC turning or milling machining accuracy. The machining accuracy of turning and milling can generally reach 0.02mm. However, due to the comprehensive influence of the thinning of the material, the stress rebound of the material, the precision of the clamping and other factors, the precision of the spinning process can not reach the precision level of the milling process. In general, the forming diameter accuracy of stainless steel is mm-1mm 0.3, and the forming accuracy of aluminum is 0.5-1.5mm.
2. Spinning Product Length Accuracy
Duespinning processingAlmost no cutting process is involved, so most of the time, the length accuracy of the spinning product is controlled by the turning process. Taking into account the rebound of the stress after cutting part of the material, the length accuracy of the general spinning products can reach 0.1mm.
3. spinning lines of spinning products
Generally, spinning products will have slight lines. The distribution of surface lines is related to the spinning forming tool path and the size of the selected cutter wheel. However, if the product has local depressions or protrusions, it is caused by the process not being properly debugged. If the product needs to be polished, oxidized and painted, the aluminum spinning product can be treated with a calender to treat the spinning surface lines, and the stainless steel spinning product can improve the process to make the lines more uniform and fine, so as to reduce the polishing cost.
Wall thickness of 4. spinning products
The distribution of the product wall thickness will affect the performance of the product material in terms of strength. In addition to using different material thicknesses to control the product wall thickness, the product thickness can also be controlled by improving the process. The quality of spinning products, the product wall thickness is very uniform throughout.
The small series is just a judgment.spinning processingsome fundamental aspects of product quality. Due to the large number of spinning products, not only the shape is different, but also the material is quite different, so the requirements of each product are different. In addition, each technical personnel responsible for the spinning process of its molding process proficiency is also different, so the actual situation should also be based on specific product requirements, can not be generalized.
