CNC machining, also known as computer numerical control machining, has significant advantages. Firstly, CNC machining has high precision and efficiency. Through programming control, CNC machine tools can achieve machining accuracy up to the micrometer level, meeting the needs of complex and fine parts processing. Meanwhile, CNC machining can work continuously for 24 hours, greatly improving production efficiency. Secondly, CNC machining has a wide range of material adaptability. It can process various metals, non-metals, and composite materials, making product design and manufacturing more flexible. In addition, CNC machining can also achieve complex three-dimensional shape machining, providing greater innovation space for product designers. CNC machining has lower costs. By reducing manual operations, saving materials, and improving production efficiency, CNC machining helps to reduce production costs and enhance the competitiveness of enterprises.
