In the field of precision machining, the accuracy of the machining process is crucial, and CNC machining (CNC machining) and traditional machining are often compared. Which machining process is more accurate and which scenarios are suitable for each?
Traditional machining relies on the workers' operating skills and experience to complete the machining of parts by manually controlling various parameters of the machine tool, such as cutting speed, feed rate, tool path, etc. Under the operation of skilled workers, traditional machining can complete some relatively simple parts processing tasks, and for some rough machining processes that do not require particularly high surface roughness and dimensional accuracy, traditional machining tools have certain cost advantages. For example, in some small machining plants, when performing preliminary contour machining on ordinary shaft parts, traditional machining can quickly remove a large amount of excess and prepare for subsequent finishing.
However, when it comes to high-precision and complex-shaped parts machining, CNC machining shows its unique advantages. Take the CNC machining technology used by Airy Precision Machinery as an example. It can achieve extremely high machining accuracy and repeatability by accurately controlling the movement and machining parameters of the machine tool through pre-written programs. When processing complex and high-precision products such as precision molds and aerospace parts, CNC machining can control the dimensional accuracy within a very small tolerance range, usually reaching an accuracy level of ±0.005mm or even higher, which is difficult to achieve with traditional machining.
CNC machining can also easily cope with complex three-dimensional surface machining, such as the blades of automobile engines and the complex shapes of mobile phone shells. Through the combination of computer-aided design (CAD) and computer-aided manufacturing (CAM) software, the designed three-dimensional model is converted into a CNC program that can be recognized by the machine tool. The machine tool can accurately plan and cut the tool path according to the program instructions to ensure that each processing part can achieve the accuracy and shape required by the design, greatly improving production efficiency and product quality stability.
In terms of mass production, CNC machining has an incomparable advantage. Once the program debugging is completed, the machine tool can automatically and efficiently perform batch processing, and the processing accuracy of each part can be kept highly consistent. This can effectively ensure the quality and performance stability of the product, reduce the scrap rate, and improve production efficiency for industries that need to produce a large number of high-precision parts, such as electronic equipment manufacturing and medical device production.
In contrast, in traditional machining, it is difficult to ensure that the machining accuracy of each part is completely consistent during mass production due to the inevitable errors and fatigue factors of manual operation, and the production efficiency is relatively low, which makes it difficult to meet the needs of modern manufacturing for high-precision, high-efficiency, and large-scale production.
In summary, CNC machining has obvious advantages in terms of precision and complex parts processing capabilities, and is suitable for the processing and mass production of high-precision, complex-shaped parts such as precision molds, aerospace, and electronic equipment; while traditional machining still has its application value in the rough processing of some simple parts and occasions that are more cost-sensitive and have low precision requirements. Companies such as Airy Precision Machinery have made full use of the respective advantages of CNC machining and traditional machining, selected appropriate processing technology according to different product needs and customer requirements, and provided customers with high-quality precision machining services, driving the precision machining industry to continue to move forward.
