CNC machining is superior to machining in terms of precision, process stability and complex parts processing, which helps to improve product durability. Machining has advantages in flexible processing of special materials and shapes. The selection of processing methods requires comprehensive consideration of part characteristics, material properties and processing requirements.
In the field of mechanical processing, both machining and CNC machining (CNC machining) are important processing methods. Some people think that the durability of machined products is better than that of CNC machining. Is this true? We can analyze it from multiple angles.
Machining accuracy and durability
CNC machining has significant advantages in precision machining. Taking CNC lathe machining as an example, it can accurately control the motion trajectory of the tool, and the machining accuracy can reach the micron level. When machining complex parts, such as turning and milling composite machining, through pre-written programs, CNC equipment can stably operate according to the set parameters to ensure the dimensional accuracy and form and position tolerance of the parts. High-precision machining makes the fit between parts tighter, reduces wear caused by excessive clearance, and thus improves the durability of the product. In contrast, machining mainly relies on manual operation, and the machining accuracy is greatly affected by the worker's technical level and status. Even experienced workers may become fatigued after working for a long time, resulting in a decrease in machining accuracy, which may affect the durability of the product.
Processing process stability
The process stability of CNC machining is high. Once the program is written, the CNC equipment can maintain stable cutting parameters such as cutting speed and feed rate during the processing. In CNC milling, the CNC system can accurately control the cutting angle and depth of the tool to ensure the consistency of each processing. This stable processing technology helps to reduce microscopic defects on the surface of parts, improve the surface quality of parts, and thus improve the durability of products. During the machining process, workers may adjust the processing parameters according to their own experience and feelings. There are differences in operating habits and adjustment methods between different workers, which may lead to instability in the processing technology and affect the quality and durability of the product.
Material adaptability
In terms of material adaptability, machining and CNC machining have their own characteristics. Machining relies on the experience of workers and can flexibly adjust the processing methods when facing some special materials or irregularly shaped workpieces. For example, for materials with higher hardness, experienced workers can perform effective processing by selecting suitable tools and cutting parameters. However, CNC machining can also accurately process various materials through advanced programming technology. By simulating the machining process, CNC machining can optimize tool paths and cutting parameters in advance to adapt to the machining requirements of different materials, ensure machining quality, and thus ensure the durability of the product.
Complexity and durability
For parts with simple shapes, machining may produce durable products with its flexibility and low cost while ensuring a certain machining quality. However, for parts with complex shapes, the advantages of CNC machining are highlighted. CNC machining can complete the machining of complex surfaces and special-shaped structures through multi-axis linkage to ensure that the design requirements of the parts are met. When precision machining complex parts, CNC machining can better ensure the accuracy and quality of parts, thereby improving the durability of products.
The durability of machined products is not necessarily better than that of CNC machining. CNC machining has advantages in precision control, process stability and complex parts machining, which help to improve the durability of products. Machining has certain advantages in flexibility and handling of special situations. In actual production, the machining or CNC machining method should be comprehensively selected according to factors such as the characteristics of the parts, material properties, and processing requirements to ensure the production of durable products.
