Reasons and solutions for the loud noise of the main shaft of the cutting machine

The main shaft has noise when working, and the sound level is not stable. This is mainly caused by the waviness of the surface of the parts of the wood door cnc router machine or woodworking engraving machine. It is necessary to improve the surface processing quality of the bearing raceway and improve the accuracy of the shaft and the bearing seat. In actual operation, in the face of some noises from the spindle, there are mainly the following four types:

1. The sound of pattering: the accuracy of the retainer, the selection of bearings with small clearance or the application of preload to the bearings, the reduction of moment loads, the reduction of installation errors, and the selection of good grease.

2. Impurity sound: choose good grease, cleanliness before grease injection, strengthen the sealing performance of bearings, and cleanliness of installation environment.

3. Humming sound: It mostly occurs when the lubrication state is not good, and the motor with ball bearings at both ends in winter is mainly an unstable vibration generated under the influence of axial vibration when the shaft alignment performance is not good.

4.the sound of da da: improve the surface processing quality of the bearing raceway, reduce the waviness amplitude, reduce the bump, correct the clearance preload and fit, check the operation of the free end bearing, and improve the precision installation method of the shaft and the bearing seat .

During engraving machine wood cnc router processing, the spindle is an important part, which plays a large role, is prone to problems, and sometimes produces a lot of noise. If there is a buzzing sound during work, there is a problem with the spindle and it cannot complete the work under load. It is recommended to replace the spindle or repair it.
