Grinding Process Sound :

Grinding Analysis Process – Elaso AG

2021-5-28  Sound propagating in a solid is called structure-borne sound. This sound is used to monitor grinding machine processes. If the grinding wheel touches the workpiece, a structure-borne sound is created. The intensity and frequency of the generated sound depends on various factors: the grinding performance, the type and condition of the grinding ...
