Is It Better To Use Water-cooled Spindle Motor Or Air-cooled Spindle Motor For Engraving Machine?
Jan 22, 2019

Many customers who want to buy engraving machines will ask this question. In order to solve this problem, the differences between water-cooled spindle motor and air-cooled spindle motor of engraving machine are distinguished one by one. I believe it will be helpful when you choose to buy engraving machine. The main differences between water-cooled spindle motor and air-cooled spindle motor of engraving machine are as follows:

1. Water-cooled spindle motor, as its name implies, uses water circulation to cool the heat generated by high-speed spindle rotation. This method works well, because the temperature after circulation will not exceed 40 degrees. Air-cooled spindle motor uses fan to heat, its effect is certainly not as good as water-cooled.

2. Noise. Water-cooled spindle motors are basically silent, but air-cooled spindle motors are loud.

3. Service life. The service life of water-cooled spindle motor is much longer than that of air-cooled spindle motor because it should pay attention to maintenance, frequent water change or use industrial water cooler.

4. Accuracy. Axial and radial runout of water-cooled spindle motors are basically below 0.003 mm, which is far less than that of air-cooled spindle motors.
