What are the advantages of CNC machine tools compared with traditional machine tools?

With the development and update of digital technology, the technical application of CNC machine tools has become more mature. Let's list the advantages of CNC machine tools compared with traditional machine tools.

1. Good processing accuracy

The machining accuracy of CNC machine tools can generally reach 0.05-0.1MM. CNC machine tools are controlled in the form of digital signals. Every time the CNC device outputs a pulse signal, the moving parts of the machine tool move by a pulse equivalent (usually 0.001MM), and the machine tool progresses. The backlash of the transmission chain and the average error of the screw pitch can be compensated by the CNC device. Therefore, the positioning accuracy of the CNC machine tool is relatively high.

2. Highly flexible

Processing parts on CNC machine tools mainly depends on the processing program. It is different from ordinary machine tools. There is no need to manufacture or replace many molds and fixtures, and there is no need to frequently readjust the machine tool. Therefore, CNC machine tools are suitable for situations where the parts being processed are frequently replaced, that is, they are suitable for the production of single pieces, small batches of products and equipment for new products, thus shortening the production preparation cycle and saving a lot of cost of process equipment.

3. Good productivity

CNC machine tools can effectively reduce the processing time and auxiliary time of parts. The spindle sound speed and feed range of CNC machine tools are large, allowing the machine tools to perform powerful cutting with large cutting amounts. CNC machine tools are entering the era of high-speed processing. The speed of the moving parts of CNC machine tools is suitable for movement and positioning and high-speed cutting, which greatly improves productivity. In addition, when used in conjunction with the tool magazine of the machining center, it can realize continuous processing of multiple processes on one machine tool, reducing the inter-process turnover time of semi-finished products and improving productivity.

4. Stable and excellent 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 paths will be the same, and the parts will have good consistency and stable quality.

5. Utilize production management modernization

The processing of CNC machine tools can accurately estimate the processing time in advance, standardize and modernize the tools and fixtures used, and easily realize the standardization of processing information. It has been organically integrated with computer-aided design and manufacturing (CAD/CAM) (with actual reports Mainly), the combination is the basis of modern integrated manufacturing technology.

6. Actual results mainly depend on working conditions

After the CNC machine tool is adjusted before processing, the program is input and started, and the machine tool can automatically and continuously process until the end of the processing. All the operator has to do is program input, editing, parts loading and unloading, tool preparation, processing status observation, parts inspection, etc. The labor intensity is greatly reduced, and the machine tool operator's labor tends to be intellectual work. In addition, machine tools are generally combined, which is both clean and safe.
