The engraving tools of wood engraving machines are often the most wearable parts for the parts used for engraving in the production work. If you do not pay attention to the problems such as the maintenance and inspection of the engraving tools, you will continue to use the production work. There is no small impact. Then we should pay attention to what we usually use when we use the engraving machine. How to maintain the knife after the work is finished. Next, follow the CNC network Xiaobian to understand the reasons for the problem of engraving machine engraving knife. Woodworking engraving machine engraving knife maintenance related content!
1. Check before starting 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 woodworking engraving machine to move back and forth twice, and start the operation.
2. The wood-cooled spindle woodworking engraving machine 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. The circulating water should be as much as possible. Capacity water tank.
3. Regularly clean the heat dissipation ventilation system of the woodworking engraving machine circuit box. Please check the operation of each fan on the electric control box regularly. Clean the dust in the electric control box with a vacuum cleaner regularly, check whether the terminal screw is loose, to ensure the circuit. Safe and reliable use.
4. Clean the dust debris on the exposed rail (light rod) and clean it with No. 2 oil. After cleaning, add butter or No. 2 lithium grease.
5. Clean the sensor (optocoupler, proximity switch) to prevent the dust powder from sticking to the sensor, affecting its sensitivity or causing false touch.
6. Move the machine head to the lower left or lower right position to prevent collision and then cut off the power supply; never pull the plug with power.
7. Woodworking engraving machine maintenance when not in use for a long time: When the woodworking engraving machine is not used for a long time, it should be energized 1-2 times a week, especially in the rainy season with large environmental humidity, so that the engraving machine can run for an hour or so. 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.
8. Maintenance of the inverter: 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.
9. After one day's work is completed, first remove the engraving knife, so that the spindle chuck and the lock nut are 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.
10. The door of the electric 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 element. The insulation resistance between devices drops, and even components and boards are damaged.
11. Regularly check the screws of the various parts of the machine for looseness.
12. Vacuum pump maintenance:
The wire mesh in the suction port of the water circulation air pump is used to prevent the foreign dust particles from entering the pump body. The filter screen should be kept clean at any time to avoid the blockage and cause the pumping speed to drop. When the pump is not in use, it should be energized every few days. Minutes to prevent the long rust of the pump body from working properly.
b Tongyou vacuum pump should also loosen the wing nut, remove the paper filter core and regularly clean the filter with high pressure gas. It is found that the filter element is not ventilated or damaged, and should be replaced in time. According to the length of use, the high pressure oil gun can be used to oil the bearings.
13. Operate in strict accordance with the instructions for use of woodworking engraving machines and comply with safe use specifications.
