Which is better for air-cooled spindle and water-cooled spindle?

Post time:2019-07-16    By:EAAK    Clicks:
The main axis of the engraving machine is divided into water cooling and air cooling. For the engraving machine main shaft, the air cooling is better or the water cooling is better. Many customers have some doubts. Today, Xiaobian listed the engraving machine water-cooled spindle motor and air-cooled spindle motor mainly have the following differences.
In fact, from the internal structure, the air-cooled main shaft and the water-cooled main shaft are the same, except that the air-cooled main shaft is cooled by the heat generated by the high-speed rotation of the main shaft by the fan, and the water-cooled main shaft reduces the temperature of the main shaft by water circulation.
1. Heat dissipation method: The water-cooled spindle motor uses water circulation to cool the heat generated by the spindle after high-speed rotation. This method will be very effective, because the temperature after circulation will not exceed 40 degrees, and the air-cooled spindle motor uses a fan to dissipate heat. It is not as effective as water.
2. Noise: The water-cooled spindle motor is basically no noise, but the air-cooled spindle motor is very loud.
3. Service life: Because the water-cooled spindle motor should pay attention to maintenance, change water frequently or use industrial water cooler, its service life is much longer than that of air-cooled spindle motor.
4. Accuracy: The axial and radial runout of the water-cooled spindle motor are basically below 0.003 mm, which is far from the air-cooled spindle motor (domestic)!
When customers purchase the engraving machine, they should combine their own actual conditions, such as the working time of the engraving machine and the size of the workpiece. It needs to be explained to the sales staff to avoid some trouble. As for whether to choose water cooling or air cooling, it needs to be based on actual needs. Decide, compare the difference between the two, choose the one that suits your business.
