In order to prolong the working life of the servo system, the following issues should be paid attention to during use. For the use environment of the system, five elements of temperature, humidity, dust, vibration and input voltage need to be considered. Regularly clean the cooling and ventilation system of the CNC device. It should be checked frequently whether each cooling fan on the numerical control device works normally. It should be checked and cleaned every six months or a quarter depending on the environmental conditions of the workshop.

When the CNC machine tool is idle for a long time, the CNC system should also be regularly maintained. First of all, the CNC system should be energized frequently, and the machine tool should be allowed to run without load when it is locked. In the rainy season when the air humidity is high, electricity should be turned on every day, and the moisture in the CNC cabinet should be driven away by the heat of the electrical components themselves, so as to ensure the stable and reliable performance of the electronic components. Practice has proved that machine tools that are often parked and not used are prone to various failures when they are turned on after the rainy season.
