PROBLEM TO BE SOLVED: To provide a multiple spindle machine efficiently machining with high accuracy while avoiding trembling vibration, and also to provide a workpiece machining method. SOLUTION: Whether trembling vibration is generated to a machining tool or a workpiece is detected by a vibration detecting sensor. In the case trembling vibration is generated, the rotating speed of the machining tool is increased, and if the trembling vibration still continues, the amount of depth of cut per one rotation of the machining tool is decreased to suppress the trembling vibration generated during machining.
