<P>PROBLEM TO BE SOLVED: To provide a delivery device for a workpiece in a machine tool, which is inexpensive and superior in versatility. <P>SOLUTION: In a machine tool in which a cutting oil supply passage through which cutting oil supplied to a machining position of the machine tool circulates is formed inside a spindle of the machine tool, a delivery device for the workpiece in the machine tool includes a delivery tool 10 mounted on the spindle and delivers the workpiece machined by the machine tool from the machining position to the outside of the machine tool by the delivery tool. The delivery device includes: an inflow passage 35 which is formed inside a tool body 30 of the delivery tool and opens on a front surface of the tool body while in communication with the cutting oil supply passage and into which the cutting oil can flow from the cutting oil supply passage; and a delivery member 31 which is a cylindrical body for closing a front side of the tool body, advances and retreats by being slidably fitted on an outer surface of the tool body, and goes forward along the outer surface of the tool body by a pressure of the cutting oil flowing into the inflow passage and flowing out from the opening of the tool body to deliver the machined workpiece to the outside of the machine tool. <P>COPYRIGHT: (C)2013,JPO&INPIT |
