CNC stands for Computer Numerical Control. The direct meaning is computer numerical control (control), which is a processing technology (technology) widely used in the manufacturing industry. It can also be said to be a sign of today's manufacturing industry. It is easy to achieve with CNC. Axis linkage (Multi-axis linkage refers to the simultaneous processing of multiple coordinate axes (including linear coordinates and rotational coordinates) on one machine tool, and simultaneous coordinated movement under the control of the computer numerical control system (CNC).) For example, if you leave the CNC , using ordinary machine tools, the processing of the hook surface is almost impossible.

In addition, flexible manufacturing systems can be easily implemented. To put it simply, ordinary machine tools are processed by people directly controlling the machine tools, while CNC is a human-controlled numerical control system to control the processing of machine tools, so as to achieve more complex and higher-speed processing.

① Reduce the number of tooling, process parts with messy shapes, and eliminate messy tooling. If you want to change the shape and size of the part, you only need to modify the part processing program (procedure), which is suitable for the development and modification of new products.

②The processing quality is stable, the processing precision (accuracy) is high, and the repeatability is high, which is suitable for the processing requirements of aircraft.

③In the case of multiple varieties and small batches, the output power is high, which can reduce production preparation, machine tool adjustment and process inspection (process inspection refers to preventing unqualified products from flowing into the next process. The calculation of the machining center affects the products and effects of the process The time for inspection of the main process elements of product quality, due to the use of better cutting volume, the cutting time is reduced.

④ It can process complex shapes that are difficult to process by conventional methods, and even parts that cannot be observed.

The price of ordinary milling machines is low, but the mass production efficiency is low, the processing quality is greatly affected by the operator's technical level, and the processing consistency is not good. CNC processing has high batch production efficiency, good processing consistency and stable quality. However, the cost of machine tools is expensive, and when the processing volume is small, programming takes a lot of time and effort, and requires higher-level maintenance personnel.
