One of the important components of the woodworking engraving machine is the main shaft, and the main shaft will generate a lot of heat during the working process, which will cause corresponding troubles to the use of woodworking machinery. Therefore, most of the main shafts of woodworking machinery are equipped with cooling devices.

The commonly used water-cooling devices for woodworking engraving machine spindles are mainly air-cooled and water-cooled. Below, Superstar CNC and you will learn about the differences between these two spindles.


What they have in common: From the perspective of internal structure, the two are unified. In terms of motor control methods, almost all water-cooled ones are controlled by frequency conversion, while air-cooled spindles are not, which can be controlled by frequency conversion and non-frequency control.

The difference between water-cooled spindle and air-cooled spindle:

1. The water-cooled spindle uses water circulation to cool the spindle, and the heat generated by the spindle will not exceed 40 degrees after the water circulates, while the air-cooled spindle uses air circulation to dissipate heat.

2. Noise: The water-cooled spindle is relatively quiet, and the air-cooled spindle is relatively noisy.

3. Due to the different engraving processes of the engraving machine, the selection of the spindle will also be different. The water-cooled spindle is suitable for crafts with long engraving time and fine workmanship, such as embossing; while the air-cooled spindle is suitable for crafts with short working time, such as making doors and furniture.

4. The water-cooled spindle should pay attention to maintenance and change the water frequently, otherwise there will be scale phenomenon, which will affect the use of the machine; while the air-cooled spindle will be easier to use and more popular with customers.
