Consisting of a main shaft device having a main shaft and a rolling bearing with an inner ring fixed to the outer periphery of the main shaft, and a housing that supports the outer ring of the bearing and surrounds the main shaft device. In a jet-lubricated spindle that is jet-lubricated, an air introduction passage passes through the housing to reach the main shaft and introduces compressed air from the outside;
The air introduction passage includes an air pocket defined between the main shaft and an oil pocket adjacent to the air pocket from which lubricating oil leaks, and the lubricating oil in the oil pocket is forced into the oil pocket. A jet lubrication spindle, characterized in that it is connected to a suction means for suctioning and conveying the suction to the outside of the spindle device. 2. The suction means includes a suction passage connected to the oil pocket and penetrating the housing, and a pump connected to the suction passage, and the oil pocket is arranged near the bearing of the spindle device with respect to the air pocket. A jet lubricated spindle according to claim 1, characterized in that it is provided with a jet lubricated spindle.
