1. The air-cooled spindle has obvious noise

        With the advancement of the times, traditional manual work has been replaced by automated equipment. CNC engraving machines are a very prominent

example, and the application of engraving machines has penetrated into various industries. However, there are some problems with the use of engraving machines, 

that is, the spindle of the engraving machine has noise, especially the air-cooled spindle.

2. What is the reason for the loud noise of the air-cooled spindle of the engraving machine, and how to deal with it?

       The spindle of computer engraving machine is divided into water-cooled spindle and air-cooled spindle. Generally speaking, the noise of water-cooled spindle 

is less than that of air-cooled spindle. Therefore, if there are no residents living around the customer's factory or shop, the engraving machine can be equipped with 

a water-cooled spindle. Because even if the noise is slightly louder, it won't disturb people. But if you open a factory in a residential area, when the air-cooled spindle 

is running, neighbors will come to you and complain basically every day. At this point, you can only replace it with a water-cooled spindle.

       If you notice that your air-cooled spindle is noisier or weirder than usual, most are caused by internal bearing issues. At this time, you need to replace the bearings 

of the engraving machine spindle. If the spindle is within the warranty period, you can send it directly back to the manufacturer for warranty processing. If the warranty 

expires, that's okay. Please return it to the manufacturer and arrange for a professional technician to inspect and repair it. You only need to pay a very low cost and do 

not need to find unprofessional repairs in the market. The technology and services they provide cannot be guaranteed.
