Maintenance strategy of metal engraving machine (1)

      The metal engraving machine is a combination of drilling and milling processing from the principle of machining. The various data input modes of the metal engraving machine are easy to use according to the needs! In CNC machine tools, the electric spindle usually adopts the frequency conversion speed regulation method. There are three kinds of control methods: common variable frequency drive and control, vector control drive drive and control, and direct torque control! Although the metal engraving machine is widely used, the maintenance of this piece may be easily overlooked, and the small series will let you know!

1. Check the metal engraving machine every day; if the communication line, motor line, and optocoupler line are loose, whether the voltage is stable; then turn on the power of the machine, operate the machine to move back and forth twice, and start the operation;

2. Clean the sensor (optocoupler, proximity switch) of the metal engraving machine to prevent the dust powder oil from sticking to the sensor, affecting its sensitivity or causing false touch;

3. Clean the dust debris on the exposed rail (light rod) of the metal engraving machine, and clean it with No. 2 oil. After cleaning, add butter or No. 2 lithium grease;

4. After the metal engraving machine is finished in one day, first remove the engraving knife and let the spindle chuck and the lock nut be in a relaxed state. This helps to extend the life of the spindle chuck. Then we began to clean the work surface, can be cleaned with a brush; pay attention to the work surface is usually not to accumulate debris, so as to avoid deformation of the platform;

5. The metal engraving machine of the water-cooled spindle should ensure the cleaning of the cooling water and the normal operation of the water pump. The water-cooled spindle motor must not be dehydrated. The cooling water should be replaced regularly to prevent the water temperature from being too high, and the circulating water should be as much as possible. Capacity water tank;

6. Move the metal engraving machine head to the lower left or lower right position to prevent collision, and then cut off the power; avoid unplugging the plug;

7. The metal engraving machine should be remembered for maintenance when it is not used for a long time. When the metal engraving machine is not used for a long time, it should be energized 1-2 times a week, especially in the rainy season with high environmental humidity. Let the metal engraving machine run for one hour. about. The heat of the electrical component itself is used to dissipate the moisture in the numerical control system to ensure stable and reliable electronic performance. Its inverter should also be maintained: the inverter has been debugged before leaving the factory, it is forbidden to debug and change the line privately to prevent damage to the motor or inverter caused by data input error!

     There are too many maintenance strategies for metal engraving machines, and will continue to decompose next time!
