CNC machine tools (Computer Numerical Control Machine Tools) are automated machine tools equipped with a program control system that can achieve precise machining operations through computer digital control technology. CNC machine tools control the program specified by the coding or other symbolic instructions through logical processing, decode it, input it into the CNC device through the information carrier, control the action of the machine tool, and automatically process the parts.
The main types of CNC machine tools include CNC milling machines, CNC lathes, machining centers, CNC wire cutting machines, CNC punching machines, and CNC laser cutting machines. These machine tools achieve precise machining of raw materials through different machining processes, such as milling, turning, drilling, grinding, etc. CNC machining has the advantages of stable machining quality, high machining accuracy, high repetition accuracy, complex machining surfaces, and high machining efficiency. It is widely used in automobiles, aerospace, national defense and other fields.
Among CNC milling machines, there are vertical milling machines and horizontal milling machines; some special ones also have plane milling machines, copy milling machines, etc. In this long river of development, a kind of profile processing center has also been extended. Profile processing center is a CNC equipment specially used for processing various metal or non-metal slender parts. It realizes various processing operations such as cutting, drilling, milling, sawing, etc. of materials through computer numerical control system. Its core advantages include high-precision processing, efficient production, diversified processing capabilities, high degree of automation and strong stability.
Profile processing center has great advantages in processing large and long parts. Traditional high-precision processing of materials over two meters is basically processed by segment processing or gantry processing center. However, these two processing methods are not suitable for batch processing and affect efficiency.
The emergence of profile processing center has solved this difficulty very well, breaking the traditional way of moving the workbench, adopting the way of fixing the workbench and moving the machine head to increase the longer processing stroke, and also make the processing of long parts more efficient. Although it is more difficult to maintain accuracy than traditional equipment, it can also meet the processing accuracy requirements of most workpieces.
In the early days of profile processing center, it was mainly used to process aluminum parts, PVC and other related materials. However, with the development of industry, some large, long and thick-walled aluminum parts, composite materials, steel parts, and castings are widely used, which puts higher requirements on profile processing centers. Larger, heavier and more complex profile processing centers have also emerged. The processing of 26-meter high-speed rail materials on rail transportation and the chip removal processing of aircraft materials are all tests of efficiency and precision, and profile processing centers have inherent processing advantages for such large and long parts.
