Abstract
A chip disposal device used in a machine tool for continuously expelling chips produced from a cutting tool such as a drill to another place, while a work is being processed with the tool. In this device, a hooding means (13) is slidably provided 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 by means of a cutting tool mounting member, and an air suction pipe (15) is provided for sucking the air from the space inside the hood. In addition, an air hole (11a) is formed in the shaft of the cutting tool (11) in such a manner that it is open at the tip 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 air 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 the air supplied from the compressed air supply pipe (33).
