摘要： An object of the present invention is to provide a spindle device for stabilizing a retainer with a minimum quantity of air to be supplied to the bearing. A spindle device includes: supplying unit which supplies air from three or more points spaced in a circumferential direction between outer races and inner races of bearings supporting a spindle; and control unit which controls a supply quantity of air supplied by the supplying unit in such a manner as to independently vary the supply quantity at each of the supplying points.

摘要： The present invention is to provide a machine tool in which appropriate warm-up operation can be performed. Unnecessary warm-up operation before machining is not carried out and damage of bearings caused by the warm-up operation is prevented. A controlling unit stores data of a supply amount of lubricant to bearings and a rotation speed of a main spindle in a memory unit as time-series data. When rotation of the main spindle is started, the time-series data stored in the memory unit is used to calculate an amount of remaining lubricant in the bearings and determination of necessity of warm-up operation is made based upon the stored data. A rotation speed at a start-up time of the main spindle is controlled according to the determination result.
