<p>When machining a workpiece (W) with a tool (T) detachably mounted on a spindle (12) included in a machine tool, a machining liquid supply system (42) for supplying a machining liquid into a machining region in which the tool (T) machines has a machining liquid spouting nozzle (44) having a machining liquid spouting opening (44a), the machining liquid spouting nozzle (44) is supported by a support rod (48) and a bracket (50) so as to be moved by moving means (54, 74) in radial directions and circumferential direction with respect to the axis of the spindle (12) in a region around a headstock (10) supporting the spindle (12). The diameter of the tool (T) held on the spindle (12) can be measured by an automatic tool measuring device (30) installed on the machine tool. The position of the machining liquid spouting nozzle (44) of the machining liquid supply system (42) with respect to radial and circumferential directions can be adjusted and changed according to the diameter of the tool (T) and to the change of the diameter of the tool (T) with the progress of a machining operation. <IMAGE></p> |
