Abstract: A cutting fluid supplying device for a machine tool includes a machine tool having a structure body including a bed, a column disposed on the bed, and a spindle head disposed to the column and at least one of the ejection ports for ejecting a cutting fluid. The cutting fluid supplying device for a machine tool further includes a storage tank for storing the cutting fluid to be supplied to the machine tool, at least one of the cutting fluid flow passages for connecting the storage tank and the at least one of the ejection ports, and at least one of the pumps for applying pressure to the cutting fluid to supply the cutting fluid stored in the storage tank to the at least one of the cutting fluid flow passages. The at least one of the cutting fluid flow passages is disposed to penetrate through or disposed on an outer surface of the structure body so as to allow heat exchange between the cutting fluid and the structure body.

Abstract: A spindle abnormity detection device includes a first sensor configured to measure oscillation of a spindle of a machine tool, a second sensor configured to measure radial runout of an axis of a tool unit attached to the spindle, and a computer configured to perform abnormity determination of the spindle based on an oscillation comparison result and a runout comparison result, the oscillation comparison result being obtained by comparing a detection result obtained by the first sensor with an oscillation standard of the spindle, the runout comparison result being obtained by comparing a detection result obtained by the second sensor with a runout standard of the tool unit.

Abstract: A fluid ejection device is equipped with a robot hand, which is attached to a distal end of an arm of an articulated robot, and having ejection holes therein for ejecting a cutting fluid toward a tool holder or a tool, and a controller adapted to control joints of the articulated robot, in such a manner that the robot hand moves along an axial direction (Z-direction) of a spindle in synchronism with a feeding operation by which the spindle is moved along the axial direction (Z-direction) of the spindle.

Abstract: A rotation table, center position of a rotation shaft of which is to be measured, is mounted on a table of a machine tool and includes a turning plate on which a workpiece is placed, a rotary drive for rotating the turning plate, and a rotation shaft support device that is located opposite the rotary drive and supports the turning plate. A fixture, including a rod-like member that is provided with spherical reference bodies at both ends and is disposed on the turning plate of the rotary table, is used to measure the center position of the rotation shaft of the rotary table.
