General CNC machine tools are mainly in accordance with the pre-prepared processing procedures, automatically processed parts. We put the parts of the processing craft route, process parameters and tool trajectory, displacement, cutting parameters and auxiliary functions, in accordance with the instruction code and procedures prescribed by the CNC machine format write into the processing program list, then this program list the contents of the records in the control medium, and then input to the numerical control machine tool numerical control device, thereby command machine parts.

The whole process from the analysis of part drawings to the production of control media is called the preparation of numerical control programs. The difference between CNC machine tool and ordinary machine tool processing parts is that the control machine tool is automatic processing parts according to the program, and the ordinary machine tool to be operated by people, as long as we change the control machine tool action program can achieve the purpose of processing different parts. Therefore, CNC machine tools are especially suitable for processing small batch and complex shape requirements of high precision parts because CNC machine tools in accordance with the program to process parts, programming personnel compiled a good program, input to the CNC device to command the machine work. The input to the program is through the control medium.

The CNC machine tool for precision parts is composed of lightweight machine tool body, high-density AC servo motor, high-precision magnetic encoder, servo unit and motion control system. Its distinctive feature is a lightweight appearance, with complete functions in addition to the automatic tool library and conventional CNC machining center performance indicators. Compared with the conventional precision parts processing, the system has higher efficiency and lower the cost, the convenience of operation, products are competitive price and function aspects of restructuring, is a kind of can satisfy the computer numerical control, automation, high precision machining of the common requirements such as affordable products, is the production, teaching and powerful assistant of personal creation and labor.

CNC machine tools for precision parts processing are programmed and controlled by CNC machining language. When the power supply of precision parts processing center cannot be connected, if the power indicator light (green) is not bright; The safety of the power supply unit has been fused; This is caused by high input voltage, or the components of the power supply unit itself have been damaged; There are two lights on the power supply of the precision parts machining center unit. One is the power indicator light, which is green. One is the power alarm light, which is red. The power unit mentioned here includes the power input unit and the power control part. Precision parts processing center input voltage low. Please check the voltage entering the power supply unit, the allowable value of the voltage is AC200V+10%, 50HZ±1HZ, the power supply unit is bad, the element is damaged, the power indicator is on, the alarm light is gone, but the power supply cannot be connected, because the conditions of power connection are not met.

In order to improve the cutting performance, both domestic and foreign developed copper electrode wire for precision CNC machine tools, some of which are brass wire inside, zinc alloy with low melting point outside, when the fire discharge has a larger vaporization bao explosion force, is the cutting speed of wire cutting is higher, the specification is (0.10-0.30)mm; Similarly, when cutting small slots or requiring small rounded corners, tungsten or molybdenum wire can be used, with a small diameter of up to 0.02-0.06mm.
