Maintenance strategy of metal engraving machine (2)

 
     Xiaobian still remembers sharing the maintenance strategy of the metal engraving machine last time, but it is only part of it. I said that the next time I will continue to decompose, so I am still in the small series. The most important thing is honesty, then there is not much nonsense. , focus on understanding the maintenance of the metal engraving machine!

1. The metal engraving machine has a continuous running time of less than 10 hours per day to ensure the cleaning of the cooling water and the normal operation of the water pump. The water spindle motor must not be dehydrated, and the cooling water should be replaced regularly to prevent the water temperature from being too high. In winter, if the working environment temperature is too low, the water in the water tank can be replaced with antifreeze;

2. Every time the metal engraving machine is used, it is necessary to pay attention to cleaning. It is necessary to clean the dust on the platform and the transmission system, and regularly and weekly (weekly) lubricate the transmission system (X, Y, Z three axes). (Note: X, Y, Z three-axis polished rods are maintained with engine oil; high-speed butter is added to the screw; in winter, if the working environment temperature is too low, the PRTT ball screw, polished rod (square rail or circular guide) should be gasoline first. Rinse and clean, then add the oil, otherwise it will cause excessive resistance of the machine transmission part and cause the machine to be misaligned.);

3. When performing maintenance inspection on the metal engraving machine, be sure to cut off the power supply, and wait until the monitor has no display and the main circuit power indicator is off before proceeding;

4. The metal engraving machine should be used to inspect the fasteners for about three months, and the fastening screws on both sides of the gantry, the fastening screws of the screw nut, and the fastening screws on both sides of the motor are fastened;

5. Regularly clean the heat dissipation ventilation system of the metal engraving machine circuit box. Please check regularly whether the fans on the electric control box work normally. Clean the dust in the electric control box with a vacuum cleaner regularly, check if the terminal screws are loose, to ensure the circuit. Safe and reliable use;

6. The door of the metal engraving electromechanical control box should be opened as little as possible. It is forbidden to open the door. When engraving, there will be dust, wood chips or metal powder in the air. Once they fall on the circuit board or electronic device in the electric control box, It is easy to cause the insulation resistance between components to drop, and even cause damage to components and circuit boards;

7. Regularly check whether the screws of each part of the metal engraving machine are loose;

8. Strictly follow the instructions for using the metal engraving machine and observe the safe use specifications.

    Metal engraving machines are also life-like as human beings. It is very important to maintain regular maintenance of all parts of metal engraving machines. This can eliminate many hidden dangers in the bud and prevent a serious accident. Operators should develop good habits that are often used to maintain equipment!

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!
