The switch or shaft fan usually installed on the door can circulate the air inside and outside the cabinet, and promote the heat dissipation of the heating devices or components in the electric control cabinet. Therefore, it is necessary to check whether each cooling fan on the CNC cabinet is working properly every day. Depending on the working environment, check whether the air duct filter is blocked every six months or quarterly. There is too much dust on the Xudai network, which needs to be cleaned up in time, otherwise the temperature in the CNC cabinet will increase, and the breeding spinning cannot run reliably, and even cause an overheating alarm.
1. Regular maintenance of the input/output device of the CNC system of the CNC machine tool
Most of the products currently used in the 1980s are equipped with photoelectric paper tape readers, through which CNC system parameters, part programs and other data can be input into the CNC registers. This will cause errors in reading information. For this reason, it is necessary to clean the photoelectric head, paper tape pressure plate and other components regularly. The paper tape reader is also the only moving part in the CNC system. In order to make the transmission mechanism run smoothly, the driving roller, guide roller and pressure roller must be regularly cleaned and lubricated.
2. Always monitor the voltage of the power grid of the CNC system
Usually, the grid voltage fluctuation range allowed by the numerical control system is -10%~-15% of the rated value. If it exceeds this range, the numerical control system will not work stably, and it will cause damage to important electronic components. Therefore, it is necessary to use Always pay attention to the fluctuation of grid voltage. For areas with poor power grid quality, the AC voltage stabilizer device used in the CNC system of the Communist Youth League should be used in time, which will significantly reduce the failure rate. To this end, it is necessary to constantly monitor the grid voltage used by the numerical control device.
