UNIVIB Ltd - AVAS vibration monitoring systems for roll

A primary function of the system is to warn of the presence of chatter and other abnormal vibrations while grinding. It is particularly applicable to machines that are not always continuously manned as it records a vibration history for the roll and also computes a cumulative Roll Quality Index (RQI) which provides a simple indication of the likelihood of the presence of chatter marks in the ...

Vibration Analysis

RGB Engineering can provide a vibration analysis to investigate the effects of "forced" vibration - unbalances, bearing noise, runouts, belt problems, etc. In addition, arrangements can be made for a complete "modal analysis" of the roll grinder, should it be warranted, which will pinpoint structural weaknesses, stiffness and damping limitations, and general machine instabilities.
