Characteristics of CNC Machining Technology:
Process concentration:
CNC machine tools generally have tool holders and tool libraries that can automatically change tools. The tool change process is automatically controlled by the 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 workshop.
(2) Reduce or no intermediate links (such as intermediate detection of semi-finished products, temporary storage and handling, etc.) to save time and manpower.
automation:
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 numerical control worker who does not need programming can be trained in a very short time (for example, a numerical control lathe worker can be trained in a week, and a simple processing program can be written). Moreover, the precision of the parts processed by CNC workers on CNC machine tools is higher than that of ordinary workers on traditional machine tools, and the time is saved.
(2) Reduce the labor intensity of workers:
CNC workers in the processing process, most of the time are excluded from the processing process, very labor-saving.
(3) Stable product quality:
The processing automation of CNC machine tools eliminates the fatigue, carelessness and human error of workers on ordinary machine tools, and improves the consistency of products.
(4) High processing efficiency:
The automatic tool change of CNC machine tools makes the machining process compact and improves the labor productivity.
High flexibility:
The traditional general-purpose machine tools are flexible but inefficient; The traditional special aircraft, although highly efficient, has poor adaptability to parts, high rigidity and poor flexibility, and is difficult to adapt to frequent product modifications brought about by the fierce competition in the market economy. As long as the program is changed, new parts can be processed on the CNC 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 processing ability：
Machine tools can accurately process all kinds of contours, but some contours cannot be machined on ordinary machine tools. CNC machine tools are especially suitable for the following occasions:
(1) Parts that cannot be scrapped.
(2) New product development.
(3) Processing of urgently needed parts.
Numerical control technology has a far-reaching impact on the implementation of automatic operation.
