The cnc router spindle is an electric spindle that can be processed at high speed. It is widely used in some small and medium-sized cnc router equipment. It can be mainly used for high-speed engraving, drilling and milling, punching, etc., involving a wide range of industries.

cnc router spindle is a relatively accurate name in this industry. Because of local differences, it may be called differently. Some places are referred to as high-speed spindles, some are referred to as cnc router spindles, and some are called engraving electromechanical spindles. It's the same.

　　Some customers' cnc routers need water-cooled spindles, why do some customers' cnc routers need air-cooled spindles? What is the difference between them? How to save money for customers?

　　The difference between the water-cooled spindle and the air-cooled spindle in the spindle of the cnc router:

　　 1. Service life, water-cooled spindles should pay attention to maintenance, frequent water changes or use industrial water coolers. The service life of such spindles is much longer than that of air-cooled spindles!

　　2. Accuracy. The axial and radial runout of the water-cooled spindle is basically below 0.003 mm, while the air-cooled spindle (domestic) is far behind!

3. Water cooling, as the name implies, uses water circulation to cool the heat generated by the spindle after high-speed rotation. This effect will be very good, because the temperature of the water after circulation (commonly tested) will not exceed 40 degrees; the air-cooled spindle uses a fan. To dissipate heat, the effect is definitely not as good as water cooling;

　　4. Noise. The water-cooled spindle is basically no noise, but the air-cooled spindle is very loud.

　　Through the above introduction about the spindle motor of the cnc router, I believe that everyone now has an understanding of the similarities and differences between water cooling and air cooling. If you have any questions or suggestions, please communicate and contact us in time.

　　 All stone cnc routers use constant-power water-cooled spindles. Generally speaking, the knives of stone cnc routers and the bearings of the water-cooled spindle are vulnerable parts. Tool damage is relatively common and can be easily seen. Then the spindle bearing is hidden in the spindle. How to judge whether the spindle bearing is damaged. After the bearing of the main shaft is damaged, it will make an abnormal sound, which is easy to distinguish. How to replace the bearing after it is damaged?

At the top of the spindle, we will see a very colored upper cover with some hexagon socket screws. We can open it with a wrench; there is a round cover with a hole in the center of the spindle, and there is a hole beside the spindle. There is also a hexagon socket screw inside. Unscrew this screw; then you can take off the dome cover; there is a screwable part on the casing under the main shaft. We use 2 wrenches, one is stuck on it, If one is stuck underneath, you can unscrew it; at this time, the black cover underneath can be removed, and the rotor can also be taken out. Take the bearing and go to the hardware market to buy the same one and replace it. It should be noted that when replacing the black cover, it must be tight to prevent the upper cover from leaking. Once there is a leak, it may cause the spindle of the stone cnc router to short-circuit.

　　 The above is the difference between the water-cooled and air-cooled spindles of the cnc router. If you have any questions, you can contact our online customer service to answer you.
