In order to clarify the mechanism of chatter mark generation in surface grinding by using horizontal spindle-reciprocating table type machines, experiments are conducted to measure the relative displacements between a grinding wheel head and a work table during various grinding operations, the dynamic characteristics of the surface grinding machines and the undulations of the finished surfaces. It is found that the dominant causes of the chatter marks are the rocking mode vibration of machines, the vibration having the period of the wheel rotation, the tuning-fork mode vibration excited by grinding forces during rough grinding operations and the pulsation of hydraulic oil pressure. It is also found that the chatter marks due to the wheel rotation often change their appearances according to the variation of the speed and stroke of the work table, in spite of constant machine settings.
