The difference between the woodworking engraving machine Weihong system and the new generation system

Most of the systems used in our woodworking engraving machines are Weihong's systems. Sometimes the price of the Weihong system and the new generation system that the engraving machine sellers say is similar. At this time, the price they mean is almost the same. The price of Weihong and the new generation system used in the center, but it is not the same on ordinary woodworking engraving machines. Some customers don’t know, if the new generation system is put on our ordinary woodworking engraving machine, it will not work. This is equivalent to overkill, the function of some new generation systems is not used, all do not know that customers should not install a new generation of systems on ordinary machines, this is a problem that some of our customers should pay attention to. In order to make money, some manufacturers do not know how to install new generation systems. The motor on such a machine will be easily burned. If you have already bought a machine, you must pay attention to it. After installing the new generation system, you must let it The manufacturer replaced the woodworking engraving machine with a large motor, so as to avoid the burning of the motor machine and the normal operation of the machine, which delayed our construction period.

How to carry out maintenance on the woodworking engraving machine

Woodworking carving grids are also life-like. It is very important to maintain the good condition of the cabinet door engraving machine. It is very important to maintain regular maintenance. 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. In general, the maintenance of the engraving machine includes the following aspects:
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 machine to move back and forth twice, and start the operation.
2. The engraving machine of the water-cooled spindle should ensure the cleaning of the cooling water and the normal operation of the 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. Water tank.
3. Regularly clean the cooling and ventilation system of the circuit box. Please check regularly whether the fans on the electric control box are working normally. Clean the dust in the electric control box with a vacuum cleaner regularly, and check whether the terminal screws are loose to ensure the circuit is 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. Maintenance of the engraving machine when not in use for a long time: When the 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.

How is the knife interrupted during the engraving process?

In the processing of stone engraving machines, there are sometimes scenes of broken knives. What is going on here? Someone will ask us if our tool is the best, why is there a broken knife? The following stone engraving machine Xiaobian will analyze this problem for you. It may be the following points:
1. The problem of the process, whether the machining allowance is unreasonable or not, can there be a stepped margin, so that there will be a change in the cutting force during the machining to generate vibration, which leads to the broken knife and the need to add semi-finishing. The other is whether the amount of knife can be too large.
2. Whether the surface of the stone engraving machine has been cleaned, whether the processing sequence is correct or not. These directly affect the starting speed of the engraving machine. The higher the starting speed, the more likely the vibration will occur and the broken knife will easily occur.
3. Whether the surrounding environment of the stone engraving machine is stable and whether the supplied voltage can be stabilized.
4, stone engraving machine auxiliary equipment can be smooth, whether to prevent secondary cutting, more important is the problem of the upper knife. Whether there is dust on the cutter and the chuck, and the strength of the upper knife can be too large. The chuck and nut are not complete. Whether the tool extension can be too long.
5, the status of the stone engraving machine tool, including the hardness, strength, sharpness of the tool, as well as the length of the extension, the smoothness of the rake face and so on.
6. Can the material in the stone engraving machine have impurities and the hardness is too large?
7. Is the stone engraving machine suitable for processing this kind of data? The speed of the spindle motor can be too low, the spindle motor speed is too low, and the amount of knife per tooth per turn becomes larger, so the cutting force becomes larger, which will cause breakage. Knife.

Water cooling application for popular stone engraving machine

With the increase of high-power engraving machines, the heat dissipation problem has become increasingly severe. As a new trend in the field of heat dissipation, water-cooling heat dissipation will definitely play an increasingly important role. Today, the stone engraving machine Xiaobian for you to understand the water cooling application of stone engraving machine, let's understand.
Here are some tips for cooling: The range of electrical heating depends on the insulation of the motor of the engraving machine. Generally internal insulation at high temperatures (130 degrees) will be destroyed. As long as it does not exceed 130 degrees, the motor will not be damaged, but at this time, the surface temperature is below 90 degrees. Therefore, it is normal for the motor surface temperature to be 70-80 degrees. A simple temperature measurement point thermometer is useful, you can also roughly determine: 1-2 seconds hand touchable, no more than 60 degrees, only hand touch, about 70, 80 degrees; a few drops of water quickly vaporized, then 90 degrees .
Stone engraving machine
The users of the engraving machine all share the same feeling. When the engraving machine is used for a long time, it will generate heat. At this time, if the motor is too hot, it will cause some negative effects. We should consider how to dissipate heat. When the temperature of the stone engraving machine is too high, you can choose to stop the machine for a period of time and continue working. You can also add heat radiation inside the motor to ensure the heat is released in time.
The heat dissipation of the engraving machine is also very important. Commonly used are passive heat dissipation and air cooling. For low power machines, passive heat dissipation can be used. The use of ambient temperature and temperature difference of the equipment, and natural cooling, is relatively simple and low cost. Suitable for low-power, short-time work equipment cooling.
Air cooling is more extensive, and most of them use this method to dissipate heat. Air-cooled heat uses a fan to blow away heat for rapid heat dissipation. However, there are also many defects in air cooling. For example, working long hours, the noise is indeed very large. Moreover, it is easy to accumulate dust, resulting in poor heat dissipation.
Water-cooling heat dissipation is to add an endothermic cold head to the surface of the heating core, which can flow through the water, thereby removing the heat and achieving the effect of cooling. Or it is equipped with a water-cooling device on the outside, working in the same way as the former. The disadvantage of water cooling is the high cost. The advantage is that the heat dissipation effect is quite good and will not be disturbed by dust.
Through the understanding of the above-mentioned stone engraving machine, I hope to help you.
