Abstract
In a vibration suppressing device provided in a machine tool having a rotary shaft for use in rotating a tool or a workpiece, for suppressing chatter vibrations generated during rotation of the rotary shaft, an arithmetical unit performs an analysis on a vibration of the rotary shaft detected by a detector (vibrations sensors) whenever the vibration is detected and a computation based on a result of the analysis. An operator, while checking results of the analysis and/or the computation displayed in real time in a display unit, manipulates a manipulation element to enter a command to change a rotation speed of the rotary shaft into a rotation speed control unit (NC unit) which controls the rotation speed according to the command entered by the operator through the manipulation element.
