The main characteristics of CNC machine tools

2021-09-26

At the beginning of CNC machine tools, aircraft parts with complex surface are selected as machining objects, which is difficult to be solved by common machining methods.  The biggest characteristic of NUMERICAL control machining is to use perforated tape (or tape) control machine tool for automatic processing.  Because aircraft, rocket and engine parts have different characteristics: aircraft and rocket zero, component size, complex surface;  Engine zero, small component size, high precision.  Therefore, aircraft, rocket manufacturing department and engine manufacturing department of the choice of NUMERICAL control machine tools are different.  In the aircraft and rocket manufacturing to use continuous control of large CNC milling machine, and in the engine manufacturing both use continuous control of CNC machine tools, also use point control of CNC machine tools (such as CNC drilling machine, CNC boring machine, machining center, etc.).  

Process focus  

CNC machine tools generally with automatic tool change tool holder, tool library, tool change process by program control automatically, therefore, the process is more concentrated.  Process concentration brings huge economic benefits:  

(1) Reduce the machine covers an area, save the plant.  

The reduction or no intermediate links (such as intermediate testing of semi-finished products, temporary storage and handling, etc.), both save time and save manpower.  

automation  

CNC machine tool processing, do not need manual control tool, high degree of automation.  The benefits are obvious.  

(1) Lower requirements for operating workers:  

An ordinary machine tool of senior workers, not a short period of time can be cultivated, and a CNC workers do not need programming training time is very short (such as CNC lathe workers need a week, will also write simple processing procedures).  And, numerical control workers in numerical control machine tool processing parts than ordinary workers in the traditional machine tool processing parts of high accuracy, time to save.  (2) reduce the labor intensity of workers: CNC workers in the process of processing, most of the time is excluded in the processing process, very labor-saving.  

⑶ Stable product quality: CNC machine tool processing automation, eliminate the fatigue of ordinary machine tool workers, careless, estimate and other human error, improve the consistency of the product.  

(4) High processing efficiency: CNC machine tool automatic tool change, so that the processing process is compact, improve labor productivity.
