A good spindle can ensure the effective operation of the CNC router| and process high-quality workpieces for you. So how to choose the right spindle motor for the cnc machine? This post introduces you to the difference between the two and the advantages of each.

 

Cooling effect

The water-cooled spindle is more effective in temperature regulation. The water cooling method uses water circulation to cool the spindle, and the temperature of the spindle usually does not exceed 40 degrees after the water circulation. Because of this, for longer-running cutting and engraving projects, water cooling is more suitable than air cooling.

If you use an air-cooled spindle cnc machine for long-term work, it is best to let the spindle rest for 30 minutes after 4 hours of work, and then start working again. Continuous operation of the air-cooled spindle for more than 4 hours will cause damage and affect its service life. The water-cooled spindle can work all the time during the operation of the CNC machine, but it should be remembered that if the cooling water becomes very hot, it should be replaced in time to ensure that the cooling water is always at a low temperature. Otherwise, the cooling effect will be reduced and the spindle will be damaged.

 

Noise

The water-cooled CNC spindle basically runs silently. The air-cooled spindle generates relatively loud noise due to the operation of the cooling fan.

 

Convenience

Water-cooled spindles need to be equipped with external equipment such as water tanks, water pumps or chillers to use, while air-cooled spindles can be used directly without any external equipment, so air-cooled spindles are more convenient than water-cooled.

 

Operating environment

Water-cooled spindles face two major obstacles in the working environment. First of all, the water-cooled spindle needs to be connected to other external equipment such as water tanks and pumps. For this reason, it often takes up more space. If your shop cannot provide this condition, then the air-cooled spindle may be more suitable for you.

Secondly, water-cooled spindles are not suitable for use in areas with lower temperatures. Especially in the cold winter in the north, when the temperature is lower than 0°C, the cold water tank and water pipes will easily freeze, causing damage to the spindle. At this time, the air-cooled spindle is very suitable. If your location is cooler most of the time, choosing an air-cooled spindle for your woodworking cnc router is the best choice. It does not require additional external equipment, but also has a good cooling effect.
