(1) High Flexibility
When processing parts on CNC machine tools, it mainly depends on the processing program, which is different from ordinary machine tools. There is no need to manufacture or replace many tools and fixtures, and no frequent machine adjustments are required. Therefore, CNC machine tools are suitable for occasions where parts are frequently changed. This means they are suitable for single-piece, small-batch production and new product development, shortening the production preparation cycle and saving a large amount of process equipment costs.
(2) High Processing Accuracy
The processing accuracy of CNC machine tools can generally reach 0.005-0.1mm. CNC machine tools are controlled by digital signals. Each time the CNC device outputs a pulse signal, the moving part of the machine tool moves by one pulse equivalent (generally 0.001mm). Moreover, the backlash of the machine tool's feed drive chain and the average error of the lead screw pitch can be compensated by the CNC device. Therefore, CNC machine tools have relatively high positioning accuracy.

(3) Stable and Reliable Processing Quality
When processing the same batch of parts on the same machine tool, under the same processing conditions, using the same tools and processing programs, the tool path is exactly the same, ensuring good part consistency and stable quality.
(4) High Productivity
CNC machine tools can effectively reduce part processing time and auxiliary time. CNC machine tools have a large range of spindle speeds and feed rates, allowing for heavy-duty cutting with large cutting depths. CNC machine tools are currently entering the era of high-speed machining. The rapid movement and positioning of CNC machine tool moving parts and high-speed cutting reduce the turnaround time between processes for semi-finished products, thereby improving production efficiency.

(5) Improved Working Conditions
After a CNC machine tool is adjusted, the program is input and started, and the machine can automatically and continuously process until the end. The operator's main tasks include program input, editing, loading and unloading parts, tool preparation, observing processing status, and inspecting parts, which significantly reduces labor intensity. The work of machine operators tends to be more intellectual. In addition, machine tools generally operate in an enclosed environment, making them clean and safe.
(6) Conducive to Modernizing Production Management
With CNC machine tool processing, machining time can be accurately estimated in advance, and the tools and fixtures used can be standardized and managed in a modern way. CNC machine tools enable
