Comparison Between Air-cooled And Water-cooled Spindles

1. The water-cooled spindle motor, as the name suggests, uses water circulation to cool the heat generated by the high-speed rotation of the spindle. This method will have a good effect because the temperature after circulation will not exceed 40 degrees. The air-cooled spindle motor uses a fan to dissipate heat, and its effect is definitely not as good as water cooling.

2. In terms of noise. The water-cooled spindle motor has basically no noise, but the air-cooled spindle motor is very noisy.

3. In terms of service life. Because water-cooled spindle motors require careful maintenance, frequent water replacement, or the use of industrial water cooling machines, their service life is shorter than that of air-cooled spindle motors.

4. In terms of accuracy. The axial and radial runout of the water-cooled spindle motor is basically below 0.003 millimeters, which is far inferior to that of the domestically produced air-cooled spindle motor!

5. In terms of convenient use. Due to the need to connect the water-cooled spindle to a water pump, a bucket is needed to hold water, and a water pipe needs to be connected, especially in the cold winter in the north, which is more prone to freezing. Some customers may find it troublesome; And the air-cooled spindle won't have so many usage problems.

Summary:

Air-cooled

Advantages: Easy installation, low maintenance cost, less affected by environmental factors, can be adjusted with Taiwan Delta frequency converter, long service life, high torque, high accuracy, and low rotational vibration.

Disadvantage: High price and loud noise

water-cooling

Advantages: Low price, low working noise, good water cooling effect, suitable for high-temperature operations on hard solid wood, stone, and soft metal

Disadvantages: low torque, high maintenance cost for water circulation, somewhat complex installation (water pump), short lifespan, and significant environmental impact (pay attention to the temperature in the country)
