CNC is the abbreviation for OMputer Number Control. As a direct means of computer numerical control, it is widely used as a machining process in manufacturing, and can also be said to be a symbol of manufacturing. Now, with CNC, it is easy to achieve multi-axis linkage (multi-axis linkage refers to multiple axes on a single axis). Machine tools (including linear coordinates and rotational coordinates) can coordinate motion processing under the control of a computer numerical control system (CNC), such as surface machining. If left CNC, Processing with ordinary machine tools is almost impossible to complete

1. Greatly reducing the number of fixtures, processing parts with messy shapes does not require messy fixtures. If you want to change the shape and proportion of the parts, you only need to modify the part processing program for the development and transformation of new products.

2. Stable processing quality, high processing accuracy, high repeatability, suitable for special precision parts processing requirements.

3. Multiple varieties and small batch production situations generate high power, which can reduce production preparation, machine tool adjustment, and process inspection. Process inspection is to prevent unqualified products from entering the next process, and to record the products processed in each process and the main process factors that affect product quality inspection. It is also recorded by the processing center, and due to better use - cutting quantity reduces cutting time

4. The most difficult part of traditional machinable conventional methods is to process disordered surfaces, but CNC can achieve it, and even process some parts that cannot be observed.

Comparison: Ordinary milling machines have low mass production efficiency, and the processing quality is influenced by the operator's technical level, resulting in large deviations. Poor machining consistency CNC machining has high batch production efficiency, good machining consistency, stable quality, high degree of automation, and low production costs.

6. Finally, CNC machine tools are expensive, require fewer processing times, require more programming time, and are uneconomical, requiring programmers to have a high level of proficiency.
