With the wide application of CNC opening machine, there are also many CNC opening machine manufacturers on the market, CNC opening machine belongs to high-tech mechanical processing equipment, is controlled by CNC machining machinery, which illustrates that in the process of processing will be a variety of external disturbances, such as the change of ambient temperature, humidity, the oscillation of the surrounding magnetic field and so on.

1. The interference of the external magnetic field, because the control system of the CNC cutting machine is composed of various electronic components, each functional component has a certain voltage, frequency range, so it is very simple to be disturbed by a variety of external magnetic field, and the instability of any component, will lead to the whole processing error of the cutting machine.

2. The temperature difference, too high air humidity will affect the control system performance of CNC cutting machine, drive motor performance, when the temperature exceeds 40 degrees, the control system may be wrong, drive motor drive torque can not reach the rating, affect the normal processing of CNC cutting machine, and the temperature is too low, lead to water cycling ice, very simple lead to the main shaft burning and other problems.
