CNC numerical control machine tools (Computer Numerical Control Machine Tools) are automated machine tools equipped with a program control system, capable of achieving precise processing operations through computer digital control technology. CNC machine tools control the program specified by logical processing, other symbols, or instructions, decode it, and input it into the numerical control device through an information carrier to control the machine’s movements, thereby automatically manufacturing 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, etc. These machines achieve precise processing of raw materials through various processing techniques such as milling, turning, drilling, grinding, etc. CNC processing has the advantages of stable processing quality, high processing accuracy, high repeatability accuracy, the ability to process complex surfaces, and high processing efficiency. It is widely used in the automotive, aerospace, defense and other fields.
In CNC numerical control milling machines, there are vertical milling machines and horizontal milling machines; some special types also include flat milling machines, profiling milling machines, and so on. During this development process, a type called profile processing center has emerged. The profile processing center is a kind of CNC equipment specifically used for processing various thin and long metal or non-metal parts. It realizes various processing operations such as cutting, drilling, milling, and sawing through the computer numerical control system. Its core advantages include high precision processing, efficient production, diverse processing capabilities, high automation level, and strong stability. The appearance of the profile processing center breaks the traditional method of moving the worktable and adopts the method of fixing the worktable and moving the machine head, which enables a longer processing range and also makes long-piece processing more efficient.
In the early days of the profile processing center, the main processing materials were aluminum parts, PVC and other related materials. However, with the progress of industrial development, some large, thick-walled aluminum parts, composite materials, steel parts and castings were widely used, which placed higher requirements on the profile processing center. Larger, heavier and more complex profile processing centers have also emerged accordingly. The processing of 26-meter materials for high-speed rail and deburring processing of aircraft materials are all tests of efficiency and accuracy, and profile processing centers have inherent processing advantages for such large and long parts.
