Abstract
The present invention provides a method for machining a workpiece, which comprises the steps of: separately supplying compressed air and a liquid into a through-hole longitudinally extending through a drawbar within a spindle of a machine tool; allowing the compressed air and the liquid to separately flow through the through-hole; mixing the liquid with the compressed air in a distal end portion of the through-hole so as to make the liquid into a mist form; ejecting the resulting mist from a distal open end of the through-hole to supply the mist to a distal end of a tool along an outer periphery of the tool or through the inside of the tool; and machining the workpiece while ejecting the mist from the distal end of the tool to supply the mist to a machining part.
