Abstract: A machine tool which removal-machines a workpiece by means of a tool includes a retaining device (a workpiece spindle and a tailstock) that retains the workpiece, a support device (an in-machine robot) that supports the workpiece, in order to suppress deflection of the workpiece retained by the retaining device, and a control device that controls driving of the support device by force control having a force as a control target. Specifically, a supporting force by the support device and a machining force by a tool are measured, and the driving of the support device is controlled so that the supporting force is equal to the machining force.

Abstract: A cutting fluid tank includes: a fluid ejection apparatus configured to eject fluid toward cutting fluid containing chips and to be capable of varying at least one of a direction and a position of ejection with time in an interior of a tank body configured to store the cutting fluid containing the chips flowed from a work portion of a machine tool. The fluid ejection apparatus includes an ejection head having an ejection port rotatable about an axis of rotation. The ejection port is at a twisted position with respect to the axis of rotation, and the ejection head is rotated by a reaction force of the fluid ejected from the ejection port. Part of the cutting fluid stored in the cutting fluid tank is used as the fluid to be ejected from the ejection port.
