Description of the Invention: [Technical Field] The present invention relates to a processing machine, and more particularly to a spindle device capable of clamping a tool and performing processing to improve cooling and dust removal effects. [Prior Art] As shown in FIG. 1 and FIG. 2, a prior art processing machine spindle device (U.S. Patent No. 57,985, 87) includes a spindle unit i, a housing 2 sleeved outside the spindle unit 1. a motor 3 mounted between the spindle unit 丨 and the housing 2 for driving the spindle unit 丨 to rotate, and the front and rear sections of the spindle unit 1 are rotatably supported by the housing 2 The front and rear bearing units 4, 5 and a cooling circuit 6 disposed inside the housing 2. The cooling circuit 6 has an introduction duct 6 〇 ι extending along the axial direction of the casing 2, a front bearing cooling zone 602 which is electrically connected to the introduction duct 601 and corresponds to the front bearing unit 4, and a front bearing cooling zone 6 The 〇2 is turned on and corresponds to the motor cooling zone 603 of the motor 3 and a rear bearing cooling zone 604 which is electrically connected to the motor cooling zone 6〇3 and corresponds to the rear bearing unit 5. When the spindle device is in operation, the cooling fluid is introduced into the introduction passage 6〇1 by the cold source generator 7, and the front bearing unit 4 is first drained to the front bearing cooling region 602 to be cooled, and then drained to the motor for cooling. The zone 603 cools the motor 3 and finally drains to the rear bearing cooling zone 604 to cool the rear bearing unit 5. And by the cooling fluid flowing through the cooling circuit, the thermal friction generated by the rotational friction of the bearing and the excitation of the motor coil can be reduced.
