摘要： A machine tool in which a fluid discharge port (4) for discharging a fluid (F) supplied from a fluid supply unit is provided to a rake surface (3) of a blade tip section (2) provided at a distal end section of the cutting tool (1), which cuts the workpiece (W), and the fluid (F) is discharged from the fluid discharge port (4) toward a rake-surface (2)-facing surface of chips (D) from the workpiece (W) that slide in pressure contact with the rake surface (3), the fluid (F) discharged from the fluid discharge port (4) reducing the force with which the chips (D) that slide in pressure contact with the rake surface (3) make pressure contact with the rake surface (3), and reducing the amount of frictional heat generated by the chips (D) sliding in pressure contact with the rake surface (3).
