In order to suppress the chatter marks due to the tuning-fork mode vibration of surfacegrinding machines, which is caused by intermittent contact of the wheel and the workpieceduring grinding operation, several types of dynamic dampers are developed and their effectiveness is investigated experimentally. It was found that in all cases the amplitudes of the tuningfork mode vibrations decreased to about 1/5 of the values in original states and the chattermarks due to these vibrations were suppressed completely. It was confirmed that the proposedprocedure was fit for designing practical dynamic dampers for ordinary horizontal spindlereciprocating table type surface grinding machines.
