Roll and Strip Chatter Marks; 5th octave chatter - Innoval

This will make the marking problem more severe. The vibration frequency associated with fifth octave chatter is usually in the range 600 to 1200Hz. Another source of forced vibration in the mill is due to periodic sub-micron features on the roll surface produced during roll grinding. Forced vibrations create these features within the roll grinder.
