The feature of the CNC machining

Process concentration(CNC machining)
NC machine tools generally have tool holders and tool libraries that can change tools automatically. The tool change process is automatically controlled by program. Therefore, the process is relatively centralized. Process concentration brings huge economic benefits:
(1) reduce the floor area of the machine tool and save the plant.
(2) reduce or no intermediate links (such as intermediate detection, temporary storage and handling of semi-finished products), which saves time and manpower.

Automation(CNC machining)
When machining with CNC machine tools, there is no need to manually control the cutting tools, and the degree of automation is high. The benefits are obvious.
(1) lower requirements for operators:
A senior worker of an ordinary machine tool can not be trained in a short time, while a CNC worker who does not need programming can be trained in a very short time (for example, the CNC lathe worker needs a week and can also write a simple processing program). Moreover, the parts processed by CNC workers on CNC machine tools are more accurate and time-saving than those processed by ordinary workers on traditional machine tools. ⑵ reduce the labor intensity of workers: CNC workers are excluded from the processing process most of the time, which is very labor-saving.
(3) stable product quality: the processing automation of CNC machine tools eliminates the fatigue, carelessness and estimation errors of workers on ordinary machine tools, and improves the consistency of products.
(4) high processing efficiency: the automatic tool change of NC machine tool makes the processing process compact and improves labor productivity.

High flexibility(CNC machning)
Traditional general-purpose machine tools, although flexible, but inefficient; Although the traditional special plane has high efficiency, it has poor adaptability to parts, high rigidity and poor flexibility. It is difficult to adapt to the frequent product modification brought by the fierce competition in the market economy. As long as the program is changed, new parts can be processed on the NC machine tool, and it can be operated automatically with good flexibility and high efficiency. Therefore, the NC machine tool can well adapt to the market competition.

Strong ability(CNC machining)
Machine tools can accurately process all kinds of contours, but some contours cannot be processed on ordinary machine tools. CNC machine tools are especially suitable for the following occasions:
1. Scrapped parts are not allowed.
2. New product development.
3. Processing of urgently needed parts.
