How to choose the type of CNC machine spindle?

CNC machine mainly rely on high-performance spindles for processing, so the choice of spindles is very important for the entire machine and the entire processing process. The spindle can be used for high-speed engraving, drilling and milling, drilling, etc. When the spindle rotates at a high speed, it will generate a lot of heat. If the heat is not cooled in time, it will greatly affect the service life of the spindle and even burn the spindle. There are two main cooling methods for the spindle, water cooling and air cooling. But which cooling method is more suitable for you? Is it better to use water to cool the spindle or air to cool the spindle? This is a problem faced by many customers who need to buy engraving machines. In response to this problem, we have listed the difference between the water-cooled spindle and the air-cooled spindle of the engraving machine. Hope it will help your choice.

1.The cooling effect is different. The water-cooled spindle uses water circulation to cool the spindle. After the water is circulated, the temperature of the spindle can be kept below 40 degrees, and its cooling effect is much better than that of air cooling.

2.The noise is different. The water-cooled spindle motor basically has no noise when it is working. Compared with the water-cooled, the air-cooled spindle motor has a higher noise.

3.Service life. The service life of the water-cooled spindle can be extended by human maintenance, such as water change or the use of industrial coolers, so its service life is longer than that of the air-cooled spindle. 

4.The accuracy is different. The horizontal and vertical accuracy errors of the water-cooled spindle are basically less than 0.003 mm, which is higher than that of the air-cooled spindle.

5.The air-cooled spindle is easier to use. Since the water-cooled spindle needs to be connected to the water pipe, a bucket is needed to hold the water. If you are in an area where the winter is relatively cold and the water pipe is easy to freeze, then the air-cooled spindle is more suitable.

Tip: When choosing which type of cooling spindle, it is recommended to consider your purchase budget and the natural conditions of the location, such as local water resources and temperature. Of course, you can also propose your specific needs to us, and we will provide you with a professional solution.
