Maintenance and management knowledge of CNC engraving machines: CNC engraving machines, as a type of precision machinery, require daily maintenance and upkeep, which can greatly improve the work and learning efficiency of CNC engraving machines in China.

1. Maintenance of CNC engraving machine lines and light strips: After each machine is used, remember to clean it thoroughly. It is necessary to clean the dust on the platform and transmission system, and regularly lubricate and refuel the transmission system (X, Y, Z axes). Attention: The X, Y, and Z axis polished rods need to be maintained with oil; The screw part uses high-speed butter; In winter, if the working environment temperature is too low, the screw rod and polished rod (square or circular guide rail) should be rinsed with gasoline first, and then rinsed with oil, otherwise the resistance of the machine transmission part is too high and the machine is misaligned

2. Replacement of circulating cooling water: The daily continuous operation time should not exceed 10 hours. It is necessary to ensure that the cooling water is clean, the water pump can work normally, and the water spindle motor should not have insufficient water. Regularly replace the cooling water to prevent excessive water temperature. In winter, if the working environment temperature is too low, replace the antifreeze water tank.

3. CNC engraving machine maintenance and CNC engraving machine electrical appliances: The maintenance work inspection required by electrical enterprises must be carried out by cutting off the system power supply until there is no display on the monitor and the power module indicator light of the main circuit is turned off.
