What does "CNC" mean
CNC is an automatic machine tool with industrial control system. The control system can logically process and decode programs that have control codes or other symbolic instructions to enable the machine to move and process parts. CNC, short for Computerized Numerical Control, also known as CNC machine tools, CNC lathes, Hong Kong and Guangdong Pearl River Delta area known as computer gongs.
Mainly used for large-scale processing parts, its processing methods include turning circle, boring, turning plane and so on. Can write programs, suitable for batch production, production process of a higher degree of automation.
Since MIT 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, the numerical control technology regardless in the hardware and the software aspect, has the rapid development.
Advantages and disadvantages of CNC:
1, greatly reduce the number of tooling, processing complex shape parts do not need complex tooling. If you want to change the shape and size of parts, only need to modify the parts processing procedures, suitable for new product development and modification.
2. The machining quality is stable, the machining precision is high, the repetition precision is high, meets the aircraft processing request.
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 the cutting time is reduced by using the best cutting quantity.
4. It is difficult to process the complex surface by conventional machining method, and even can process some parts which can not be observed.
