<p>A chip disposal device used in a machine tool for continuously expelling to another place chips produced from a cutting tool such as a drill while a work is being processed with the tool. In this device, a hooding means (13) is provided slidably relative to a work (w) for forming an air-tight space around a cutting tool (11) such as a drill which is mounted on a spindle (3) of the machine tool via a cutting tool mounting part, and an air suction pipe (15) is provided for sucking air from the space inside the hood. In addition, a vent hole (11a) is formed in the shaft of the cutting tool (11) in such a manner that it is open at the leading end of the cutting tool at one end and at the other end is caused to communicate with passageways (p1, p2) open to the atmospheric area. In this case, the vent hole (11a) may be connected to a compressed air supply pipe (33) at the other end instead of being open to the atmospheric area. Furthermore, a cutting agent may be mixed into air supplied from the compressed air supply pipe (33).</p> |
