(1) Highly flexible
Machining parts on CNC machine tools mainly depends on the processing procedures. It is different from ordinary machine tools. There is no need to manufacture or replace many tools and fixtures, and the machine tools do not need to be adjusted frequently.Therefore, CNC machine tools are suitable for frequent replacement of parts.That is, it is suitable for single-piece, small-batch production and new product development, which shortens the production preparation cycle and saves a lot of process equipment costs.
(2), High machining accuracy
The machining accuracy of CNC machine tools can generally reach 0.005~0.1mm. CNC machine tools are controlled in the form of digital signals. For each pulse signal output by the CNC device, the moving parts of the machine tool move one pulse equivalent (generally 0.001mm), and the reverse gap of the machine tool feed transmission chain and the average screw pitch error can be compensated by the CNC device, therefore, the positioning accuracy of the CNC machine tool is relatively high.

(3) Stable and reliable processing quality
Processing the same batch of parts, on the same machine tool, under the same processing conditions, using the same tools and processing procedures, the tool trajectory is exactly the same, the parts are consistent and the quality is stable.
(4), High productivity
CNC machine tools can effectively reduce the processing time and auxiliary time of parts. The spindle speed and feed volume of CNC machine tools have a large range, allowing the machine to perform powerful cutting with large amounts of cutting. CNC machine tools are currently entering the era of high-speed processing. The rapid movement and positioning of moving parts of CNC machine tools and high-speed cutting have reduced the inter-process turnover time of semi-finished products and improved production efficiency.

(5) Improve working conditions
After the CNC machine tool is adjusted before processing, enter the program and start it, and the machine tool can automatically and continuously process until the processing is over.The operator is mainly responsible for program input, editing, loading and unloading parts, tool preparation, observation of processing status, inspection of parts, etc. The labor intensity is greatly reduced, and the labor of machine tool operators tends to be intellectual work.In addition, machine tools are generally closed processing, which is clean and safe.
(6) Conducive to the modernization of production management
For the processing of CNC machine tools, the processing time can be accurately estimated in advance, and the tools and fixtures used can be standardized and modernized.CNC machine tools make ​
