Spindle motor is a key component of any CNC router machine. Operator use it to perform high-speed drilling, carving, cutting and other such operations on materials, and it is widely used in a wide range of industries. A good spindle can ensure the effective operation of the cnc machine and process high-quality workpieces for you.

When the cnc router executes the carving and cutting program, the spindle runs at high speed. Air cooling and water cooling are the two most common cooling systems that work in this situation. As the name indicates, the air-cooled spindle uses a fan to dissipate heat. Similarly, the water-cooled CNC spindle adopts water circulation to cool the spindle. So, when you buy an cnc router machine, which spindle motor do you like? Water-cooled or air-cooled?

Many customers will ask: What factors should I consider when choosing the spindle of the cnc router? Of course, different types of spindle motors have different advantages, so it is very important to choose a more durable spindle for work according to actual needs. As a professional CNC manufacturer, ACCTEK will introduce you to the advantages and differences between air-cooled and water-cooled spindles, so that you can choose the right spindle motor when you buy an cnc machine.

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.

Service life

The water-cooled spindle of the wood cnc router can extend its service life by replacing the cooling water or industrial chillers. Therefore, as long as the operator pays attention to maintaining it, the service life of the water-cooled spindle is longer than that of air cooling.
