A tool changing device and a tool cleaning method capable of surely removing foreign matter such as swarf adhered to tapered portions and/or flange portions of tools (3), which serve as contact faces to be engaged by a spindle (6). There are arranged tool cleaning nozzles (9a, 9b) for spouting coolant (30) on both sides of the spindle (6) in the rotating position of a turret (4). The tool cleaning nozzles have a position and a posture such that the coolant (30) spouted from the nozzles (9a, 9b) hits against the tapered portions and/or the flange portions of the tools (3) held by the turret (4). The coolant (30) is spouted from the tool cleaning nozzles (9a, 9b) with the rotation of the turret (4) at the time of tool selection. Each time the turret (4) rotates, the tapered portions and/or the flange portions of the tools (3) held by the turret (4) are cleaned by the coolant (30). Even if foreign matter, such as swarf, is adhered to the standby tools (3) held by the turret (4), it is possible to surely remove the foreign matter, such as swarf, since the tools (3) are cleaned during the rotation of the turret (4). <IMAGE> |
