CNC machine tools from the beginning to select a complex surface with the aircraft parts as a processing object, to solve the common processing methods difficult to solve the key. The biggest feature of CNC machining is the use of perforated tape (or tape) to control the machine for automatic processing. As the aircraft, rockets and engine parts have different characteristics: aircraft and rocket zero, component size, complex surface; engine zero, small size, high precision. So the aircraft, rocket manufacturing sector and the engine manufacturing sector selected CNC machine tools are different. In the manufacture of aircraft and rocket manufacturing to the use of continuous control of large CNC milling machine, and in the engine manufacturing both the use of continuous control of CNC machine tools, but also the use of point control CNC machine tools (such as CNC drilling machine, CNC boring machine, machining center, etc.) The
Process center
CNC machine tools generally with a tool can automatically change the knife, knife, tool change process automatically by the program control, therefore, the process is more concentrated. Process brings huge economic benefits:
¢Å reduce the machine floor area, saving plant.
¢Æ reduce or no intermediate links (such as semi-finished products in the middle of detection, temporary handling, etc.), both time and save manpower.
automation
CNC machine tool processing, without manual control of the tool, a high degree of automation. The benefits are obvious.
(1) Reduced requirements for operating workers:
An ordinary machine tool of the senior workers, not a short period of time can be cultivated, and a programming without the need for NC workers very short (such as NC workers need a week can be, but also the preparation of simple processing procedures). Moreover, the NC workers in the CNC machine tools on the parts than ordinary workers in the traditional machine tool parts processing accuracy, time to save. ¢Æ reduce the labor intensity of workers: NC workers in the processing process, most of the time excluded from the processing process, very labor-saving.
¢Ç product quality and stability: CNC machine tool processing automation, eliminating the general machine workers on the fatigue, careless, estimated and other human error, improve product consistency.
¢È high processing efficiency: CNC machine tools such as the automatic tool change so that the processing process is compact, improve labor productivity.
High flexibility
Traditional machine tools, although flexible, but inefficient; and the traditional plane, although the efficiency is high, but the adaptability of the parts is poor, rigid, poor flexibility, it is difficult to adapt to the fierce competition under the market economy Product frequently modified. As long as the program changes, you can in the CNC machine tools on the processing of new parts, but also automated operation, flexible and efficient, so CNC machine tools can be well adapted to market competition.
strong ability
The machine can accurately process all kinds of contours, and some contours can not be processed on ordinary machine tools. CNC machine tools are particularly suitable for the following occasions:
1, not scrapped parts.
2, the development of new products.
3, the urgent need for processing. |
