CNC is an automated machine tool equipped with a program control system. The control system can logically process the program with control codes or other symbolic instructions, and decode it, so as to make the machine tool move and process the parts. The abbreviation CNC in English is the abbreviation of Computerized Numerical Control in English, also known as CNC machine tools, CNC lathes, and the Hong Kong and Guangdong Pearl River Delta areas are called computer gongs.
Mainly used for large-scale processing of parts, the processing methods include car outer circle, boring, car plane and so on. Programs can be written, suitable for mass production, and the production process has a high degree of automation.
Since the Massachusetts Institute of Technology developed the world’s first CNC machine tool in 1952, CNC machine tools have been widely used in the manufacturing industry, especially in the automotive, aerospace, and military industries. CNC technology is used in both hardware and software. , Both have rapid development.
Advantages and disadvantages of CNC:
1. The number of tooling is greatly reduced, and complex tooling is not required for processing parts with complex shapes. If you want to change the shape and size of the part, you only need to modify the part processing program, which is suitable for new product development and modification.
2. The processing quality is stable, the processing accuracy is high, and the repeat accuracy is high, which is suitable for the processing requirements of aircraft.
3. The production efficiency is higher in the case of multi-variety and small batch production, which can reduce the time of production preparation, machine tool adjustment and process inspection, and reduce the cutting time due to the use of the best cutting amount.
4. It can process complex profiles that are difficult to process by conventional methods, and even process some unobservable processing parts.
