CNC engraving machine maintenance includes the following aspects: every day before starting the first check; For example, whether the communication line, motor line, optical coupling line is loose, whether the voltage is stable; Then turn on the machine power, operate the machine to move back and forth twice, start work. Clean the sensor (optocoupler, proximity switch) to prevent dust and oil from sticking to the sensor, affecting its sensitivity or causing false contact.

Clean the dirt on the exposed guide rail (polished rod) and clean it with no. 2 oil. After cleaning, add butter or no. 2 lithium base fat. After a day's work, first take off the carving knife, let the spindle chuck, lock nut in the state of relaxation. It is helpful to prolong the service life of spindle chuck. Then we began to clean the work surface, with a brush; Pay attention to the work table is usually best not to pile up all the debris, so as not to deform the platform.

The engraving machine of water-cooled spindle should ensure the cleaning of cooling water and the normal work of the water pump, must not make water-cooled spindle motor water shortage, regular replacement of cooling water, to prevent excessive water temperature, circulating water as much as possible, can be replaced with large capacity water tank. Move the nose to the lower left or lower right position to prevent collision, then cut off the power supply; Do not pull the plug live.

Maintenance of engraving machine when not in use for a long time: when the engraving machine is not in use for a long time, it should be electrified once or twice a week, especially in the plum rain season with relatively high humidity, so that the engraving machine can run empty for about an hour. The use of electrical components to dissipate the moisture in the numerical control system to ensure the stability and reliability of electronic components.

Maintenance of frequency converter: the frequency converter has been debugged before leaving the factory. It is forbidden to debug and change the line without authorization to prevent the damage of motor or frequency converter caused by data input error. Regularly clean the cooling and ventilation system of the circuit box. Please regularly check whether the fans on the electric control box are working normally. Clean the dust in the electric control box with a vacuum cleaner regularly.

Should open the door of electric control box as little as possible, prohibit to open the door to work, there will be dust, wood chips or metal powder in the air when carving, once they fall on the circuit board or electronic devices in the electric control box, easy to cause the insulation resistance between components to decline, even lead to components and circuit board damage.

Regularly check the screws of all parts of the machine for looseness. Vacuum pump maintenance: the metal mesh inside the suction port of A water circulation air pump is used to prevent foreign dust particles from entering the pump body. This filter should be kept clean at any time to avoid clogging and causing pump pumping speed decline. When the pump is not in use, it should be powered on for several minutes every few days to prevent the long rust of the pump body from working normally.
