Numerical and Experimental Approach for Roll Grinding
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 selfexcited vibration excitation or socalled regenerative chatter excitation is present in the process1 A roll grinder with vibration resistance, comprising: a roll grinder bed comprising a monolithic block having a top side and a bottom side; a top plate on the top side of the block;Roll grinder with vibration dampening Voith Sulzer The grindstone is positioned to the middle of the roll (f 1 (z)=1) that is grinding stationary, and the roll has no shape error Grinding starts after 1 s and the delay is considered after 7 s The vibrations of the earlier rotation rounds keep in the deformation history of the roll surface and appear again for each new rotation roundSimulation of roll grinding system dynamics with rotor
