What are the advantages of CNC machine tools

1. Highly flexible: CNC machine tools process parts mainly depending on the processing program. Unlike ordinary machine tools, they do not need to manufacture or replace many tools and fixtures, and do not require frequent adjustment of the machine tool. Therefore, CNC machine tools are suitable for situations where parts are frequently replaced. This is suitable for single piece, small batch production, and new product development, shortening the production preparation cycle and saving 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 by one pulse equivalent (usually 0.001mm). Moreover, the reverse clearance of the machine tool feed transmission chain and the average error of the screw pitch can be compensated by the CNC device, so the positioning accuracy of CNC machine tools is relatively high.
3. Stable and reliable processing quality: When processing the same batch of parts on the same machine tool and under the same processing conditions, using the same tool and processing program, the tool path is completely the same, the consistency of the parts is good, and the quality is stable.
CNC machine tools can effectively reduce the processing time and auxiliary time of parts. The spindle speed and feed rate of CNC machine tools have a wide range, allowing the machine to perform strong cutting with large cutting amounts. CNC machine tools are entering the era of high-speed machining. The rapid movement and positioning of moving parts of CNC machine tools and high-speed cutting processing have reduced the turnover time between processes of semi-finished products and improved production efficiency.
5. Improving labor conditions: After adjusting the CNC machine tool before processing, inputting the program and starting it, the machine tool can automatically and continuously process until the processing is completed. The operator mainly engages in program input, editing, loading and unloading of parts, tool preparation, observation of machining status, and inspection of parts. The labor intensity is greatly reduced, and the labor of machine tool operators tends to be intelligent. In addition, machine tools are generally closed processing, which is clean and safe.
6. Beneficial for modernization of production management: CNC machine tools can accurately estimate processing time in advance, and the tools and fixtures used can be standardized and modernized for management. CNC machine tools use digital signals and standard codes as control information, making it easy to standardize machining information. Currently, they have been organically combined with computer-aided design and manufacturing (CAD/CAM), and are the foundation of modern integrated manufacturing technology.
