ABSTRACT:
A spindle device of a machine tool, which can prevent the liquefaction of atomized cutting fluid in atomized cutting fluid passage downstream of a straightening unit14,enhance a responsiveness to an ejecting start or stop instruction, and prevent a waste of cutting fluid. The spindle device for a machine tool has atomized cutting liquid passage (e1,e2) each having a single-shape passage section and formed inside the device ranging from the spindle1to the tip end of a cutting tool13mounted thereto in one piece, and is operated so as to eject atomized cutting tool13via the atomized cutting fluid passages (e1,e2), wherein a straightening unit14formed with a plurality of small-diameter passages h are provided in the middle of the cutting liquid passages (e1,e2).
