The onset of gauge chatter vibration occurs at high rolling speed. Usually you can only stop it by reducing the speed of the mill. It is rarely possible to stop the vibration by increasing speed if the mill is truly unstable. Typically the amplitude of vibration will rise very rapidly (in less than a second). At this vibration frequency it will be audible. Without vibration monitoring ...
