How Vibratory Polishing Machine Reduces Noise

Is there any way to reduce the noise of the Vibratory Polishing Machine ? Let's talk about you in the following small series; When the equipment fails and needs to be repaired, it will not be used for a while, and the surface of the equipment will inevitably accumulate a series of dust. At this time, the bearing will appear to be non-rotating, and noise will inevitably occur during use. So is there any way to determine if it is the noise of the Vibratory Polishing Machine? At this time, you can touch the hand continuously. If the noise of the device is very large or it is hot, then it can be determined that the motor is damaged. However, if the noise of the equipment is larger than before, and the entire polishing disc has a slight vibration, it is determined that the bearing is damaged, and then the bearing will naturally emit noise when the bearing is not moved. information about vibratory polishing machine: https://www.zhongyun-machine.com/product/vibratory-polishing-machine/
