Therefore, the three steps of excitation response, system internal transmission and acoustic radiation are the formation process of vibration noise, friction noise and impact noise.
(1) The main drive system of CNC machine tools mainly relies on gears to complete the transmission and transmission. Therefore, the meshed transmission of gears is one of the major noise sources.
(2) The assembly, preload, concentricity, lubrication conditions of the bearings and journals and bearing holes, as well as the size of the load acting on the bearings, radial clearance, etc., have a great influence on the noise. And the manufacturing deviation of the bearing itself largely determines the noise of the bearing.

The causes of the noise generated by the CNC machine tool spindle and how to solve it?
In many CNC machine tools, because the transmission system of the main shaft still uses a number of transmission shafts, gears, and bearings, vibration, noise, friction noise, and impact noise are unavoidably generated in the work. The speed change of the main drive system of the CNC machine tool is controlled by the computer under the condition that the machine tool does not stop working. Therefore, it is more continuous and representative than the noise generated by the ordinary machine tool. The mechanical system is subjected to any external excitation force and the system will vibrate in response to this excitation force. This vibrational energy propagates throughout the system. When it propagates to the surface of the radiation, this energy is converted into a pressure wave that is transmitted through the air, ie sound radiation.
