The operation and monitoring of CNC machine tools are carried out in this CNC unit, which is the brain of CNC machine tools. Compared with ordinary machine tools, CNC machine tools have many irreplaceable Features, let's take a look at the main difference between CNC machine tools and ordinary machine tools!

Summary of the characteristics of CNC machine tools

1. Strong adaptability to processing objects, CNC machine tools provide suitable processing methods for mold manufacturing; adapt to the characteristics of single-piece production of molds and other products.

2. CNC machine tools have higher machining accuracy and stable machining quality;

3. Multi-coordinate linkage of CNC machine tools can process parts with complex shapes;

4. When machining parts are changed, CNC machine tools generally only need to change the CNC program to save production preparation time;

5. The machine tool itself has high precision and rigidity, and can choose a favorable processing amount, and the productivity is high (generally 3~5 times that of ordinary machine tools);

6. CNC machine tools have a high degree of automation, which can reduce labor intensity;

7. Conducive to the modernization of production management. CNC machine tools use digital information and standard codes to process and transmit information, and use computer control methods to lay the foundation for the integration of computer-aided design, manufacturing and management;

8. The quality requirements for operators are high, and the technical requirements for maintenance personnel are higher.

Compared with traditional machine tools, the main differences between CNC machine tools are as follows:

1. High flexibility

Machining a part with a CNC machine mainly depends on the machining steps. That is, the production of a single piece, a small amount of products and the development of new products, unlike ordinary machine tools, do not need to be manufactured, replace many molds and fixtures, and do not need to readjust the machine tool frequently. Therefore, CNC machine tools are suitable for the frequent replacement of processing parts, which shortens the production preparation cycle and saves a lot of technical equipment costs.

2. High machining accuracy

The machining accuracy of CNC machine tools can generally reach 0.05-0.1MM, the moving parts of the machine tool move a pulse equivalent (usually 0.001MM), and the CNC machine tools use digital signals Form control, the machining accuracy is easier to control.

3. Stable and reliable processing quality

Machining the same batch of parts, the same machine tool, under the same machining conditions, using the same tool and machining program, the tool path 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 high-speed movement and positioning of moving parts and high-speed cutting processing of CNC machine tools greatly improve productivity. In addition, by combining with the tool magazine of the machining center, the sound speed of the spindle of the CNC machine tool and the feed range of the five-axis linkage machining center are very wide, and the machine tool can perform powerful cutting with a large amount of cutting. CNC machine tools have entered the era of high-speed processing. One machine tool can perform continuous processing of multiple processes, shortening the rotation time between processes of semi-finished products and improving production efficiency.

5. Improve working conditions

After the CNC machine tool is adjusted before processing, the input program is started, and the machine tool can automatically and continuously process until the end of processing. Operators only need to input programs, edit, load and unload parts, prepare tools, observe processing status, check parts, etc. The labor intensity is greatly reduced, and the labor of machine tool operators is becoming intellectual work. In addition, machine tools are generally combined, clean and safe.
