Analysis on Vibration of Rolling rolls Grinder

The vibration generated by the processing system during the grinding process directly affects the quality and productivity of the roll surface. If the vibration is not eliminated and suppressed in time during the semi-finishing and fine grinding processes, the straight wave vibration pattern must be mapped on the roll surface.

Numerical and Experimental Approach for Roll Grinding Process

This paper presents a study of a vibration problem in a roll grinding machine. The rolling contact between a metal roll and the grindstone may cause the pattern formation on the roll surface during the grinding operation. A self-excited vibration excitation or so-called regenerative chatter excitation is present in the process. The chatter vibrations are described by a mathematic model
