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.

How to provide the stability of the wood engraving machine system

The stability of the CNC system of woodworking engraving machine is very important. If the control system of wood engraving machine is unstable, such as the internal heating of the CNC system in summer, or the failure of the fan or hard disk, the CNC system can not work, the company needs to stop production for one week waiting for replacement. Or repair system, which is a serious loss for enterprises and manufacturers, woodworking engraving machine based on years of practical experience, summed up the following effective measures, hope to get users' reference and reference! Unstable factors include:
1. Software interpolation operation and Windows system Windows system is not a real-time operating system, suitable for office automation, but not suitable for industrial real-time numerical control, especially when the CNC system uses software for cutting and interpolation operations, the operator once cuts the inflection point Acceleration and deceleration at the beginning will immediately interrupt the cutting process.
2. High frequency CPU high frequency CPU has a large heat dissipation, must use a fan, often causes the CNC system to overheat in the summer.
3. Civil fan The civil fan runs in a harsh industrial environment such as dust and high temperature, which is inevitably worn and aged, and its service life is very limited. Once the fan is damaged, the CPU and motherboard will be damaged.
4. Civil large hard disk with mechanical rotating medium, high-speed rotation causes heat, vibration causes hard disk damage, easy to be infected with viruses, and instability is very high. All of the above are factors that cause the instability of the CNC system. How to overcome the unstable factors, Xiaobian gives you the following suggestions:
1. The hardware axis card interpolation operation replaces the software interpolation operation by the hardware axis card interpolation operation, so that the interpolation operation is performed on the bottom layer of the computer, that is, the axis card is not used, and the high-frequency CPU is not required.
2. The DOS operating system uses the single-task single-process DOS operating system to realize real-time CNC cutting through the hardware motion control axis card, avoiding the multi-tasking and multi-process of Windows causing the cutting interrupt to crash.
3. Fan-free, low-power, industrial-grade CPU uses a low-power CPU without a fan. Not only does the CPU have low heat, but it also eliminates the instability of the fan and effectively improves the stability of the CNC system.
