At the beginning of CNC machine tools, aircraft parts with complex surfaces were selected as processing objects to solve the key problems that ordinary machining methods are difficult to solve. A major feature of NC machining is the use of perforated tape(or tape) control machine tools for automatic processing. Due to the different characteristics of aircraft, rockets and engine parts: zero aircraft and rockets, large components, and complex surfaces; Engine zero, small component size, high precision. Therefore, the CNC machine tools used by the aircraft, Rocket manufacturing departments and engine manufacturing departments are different. In aircraft and rocket manufacturing, large-scale CNC milling machines with continuous control are used, while in engine manufacturing, CNC machine tools with continuous control are also used(such as CNC drilling machines, CNC boring machines, and machining centers).
Process concentration
CNC machine tools are generally equipped with knives and tool libraries that can be automatically changed. The process of changing knives is automatically controlled by the program. Therefore, the process is relatively concentrated. Process concentration brings great economic benefits:
(1) Reduce the area of machine tools and save factories.
(2) The reduction or absence of intermediate links(such as intermediate testing of semi-finished products, temporary storage and handling, etc.) saves both time and manpower.
automation
CNC machine tool processing, no manual control tool, high degree of automation. The benefits are obvious.
(1) Reduced requirements for operators:
The efficient work of an ordinary machine tool can not be cultivated in a short period of time, and the training time of a CNC worker who does not require programming is extremely short(for example, a CNC driver needs a week, and a simple processing program is also written). Moreover, the parts processed by CNC workers on CNC machine tools are more accurate than those processed by ordinary workers on traditional machine tools, and the time must be saved. (2) Reduced labor intensity of workers: CNC workers in the processing process, most of the time is excluded from the processing process, very labor-saving.
(3) Product quality stability: The automation of NC machine tools avoids the fatigue, carelessness, and human error of ordinary machine tools, and improves product consistency.
(4) High efficiency of machining: The automatic changing knife of CNC machine tool makes the processing process compact and improves labor productivity.
Flexible and high
Traditional universal machine tools, although flexible, but inefficient; Although the efficiency of the traditional special plane is very high, the adaptability to the parts is poor, the rigidity is large, and the flexibility is poor. It is difficult to adapt to the frequent modification of products brought about by fierce competition under the market economy. As long as the program is changed, new parts can be processed on the CNC machine tool, and it can be automated, flexible, and efficient. Therefore, the CNC machine tool can adapt well to market competition.
