Firstly, CNC stands for Computer Numerical Control, which combines computer technology with machining to achieve a balance between accuracy and efficiency. By pre programming, CNC machine tools can accurately locate and process workpieces according to preset instructions. This automated processing method eliminates the influence of human factors in traditional mechanical processing, greatly improving the accuracy of processing.

Secondly, CNC machining technology also utilizes advanced tools and cutting tools. Mechanical operations often require manual adjustment of tool and workpiece positions, while CNC machines can automatically complete these tasks according to predetermined programs. Through precise tool sensors and automatic tool changing systems, CNC machine tools can quickly and accurately adjust tool position and workpiece positioning, thereby improving machining efficiency.

In addition, CNC machining technology also adopts high-speed cutting and optimized cutting paths. By optimizing the cutting path reasonably, reducing the number of cutting times and cutting time, CNC machine tools can achieve high-efficiency machining. At the same time, CNC machine tools can also adjust cutting parameters based on material characteristics and workpiece shape, improving machining speed and quality.

In summary, the reason why CNC machining technology can achieve the coexistence of accuracy and efficiency is due to the application of computer technology, advanced tools and cutting tools, and optimized cutting paths. The combination of these technologies enables CNC machine tools to achieve a balance between high precision and high efficiency during the machining process.
