1. The processing and production should be carried out in strict accordance with the operation procedures and daily maintenance system
2. In production, try to avoid opening the door of CNC cabinet and strong current cabinet
This maintenance measure is mainly to avoid the presence of dust, dust and metal powder in the air of the processing workshop falling on the circuit board, resulting in the decline of insulation resistance function and the failure of the circuit board. There are also users in the summer, in order to let the numerical control cabinet cool down, open the numerical control door, let a lot of dust into the numerical control cabinet, accelerate the damage of the numerical control system.
3. The cooling and ventilation system of the numerical control cabinet should be cleaned regularly
We must pay attention to the heat dissipation and ventilation system of the numerical control cabinet, because if the system is blocked, it is easy to cause the temperature of the numerical control system to be too high, affect the normal operation of the numerical control system, and even lead to the accuracy problems of processing and production.
4. Maintain the input / output device of CNC system regularly
Now many CNC machine tools are using photoelectric tape reader, reading tape is very important, if there is pollution, it is easy to cause information error, so it is very important to maintain the system regularly.
5. Check and replace DC motor regularly
The performance of the motor has a great relationship with the brush of the DC motor. If the brush is worn excessively, the motor will be damaged. So it is very important to check and replace the motor regularly. In addition, CNC lathes, milling machines and machining centers should be checked regularly.
6. Storage batteries should be replaced regularly
The general CNC system has a charging battery maintenance circuit for the CMOS RAM memory device, the purpose of which is to keep the contents of the memory when the pen holder is not connected to the device. For maintenance personnel, even if the storage battery does not fail, it should be replaced once a year, so as to ensure the normal operation of the system. When the battery is replaced, attention should be paid to ensure that the information of RAM will not be lost when the CNC system is powered on.
7. Maintain spare circuit board
Spare circuit board is rarely used. If the printed circuit board is not used for a long time, it should be allowed to run in the numerical control system for a period of time to avoid damage caused by long-term limitation.
