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.
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 .

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.
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.
