It's too hot in summer. Why can't you open the CNC cabinet for cooling?

[Abstract]:
Maintenance of standby circuit board When the standby printed circuit board is not used for a long time, it shall be installed in the CNC system for power on operation for a period of time to prevent damage.
       In summer, in order to make the CNC system work overload for a long time, it is advisable to open the door of the CNC cabinet to dissipate heat?
There are oil mist, dust and even metal powder in the air of the machining workshop. Once they fall on the circuit board or electronic devices in the CNC system, it is easy to cause the insulation resistance between components to drop, or even damage the components and circuit board.
Open the door of the NC cabinet to dissipate heat, which will eventually lead to accelerated damage of the NC system. Therefore, it is too hot in summer, so it should be minimized to open the door of the NC cabinet and the strong current cabinet. So how to maintain the CNC system?

       1. Strictly abide by the operating procedures and daily maintenance system
Vertical processing operators should strictly abide by the operating procedures and daily maintenance system. The technical and professional quality of operators is an important factor affecting the frequency of failure. When the machine tool breaks down, the operator shall pay attention to keep the site and explain the situation before and after the break down to the maintenance personnel, so as to analyze and diagnose the cause of the break down and eliminate it in time.
2. Prevent the system from overheating
Check whether the cooling fans on the numerical control cabinet work normally. Check whether the air duct filter is blocked every half a year or every quarter. If the dust on the filter screen accumulates too much and is not cleaned in time, the temperature in the numerical control cabinet will be too high.
3. Regular inspection and replacement of DC motor brush
The excessive wear of DC motor brush will affect the performance of motor, even cause motor damage. Therefore, the brush of the motor shall be inspected and replaced regularly. CNC lathe, CNC milling machine, etc., should be checked once a year.
4. Regularly check and replace the storage battery
Generally, the CMOS RAM memory device in the CNC system is provided with a rechargeable battery maintenance circuit to ensure that the contents of the memory can be maintained during the period when the system is not powered on. In general, even if it has not failed, it should be replaced once a year to ensure the normal operation of the system. The replacement of battery shall be carried out under the power supply condition of CNC system to prevent the loss of information in RAM during replacement.
5. Maintenance of standby circuit board
When the standby printed circuit board is not used for a long time, it shall be installed in the CNC system for power on operation for a period of time to prevent damage.
