PURPOSE: To increase the number of tools capable of being handled in a short time or for a correct positioning for replacement by providing a moving device for moving each of or a plurality of those tools installed collectively almost without a clearance around the periphery of a rotor installation part to an area longer than a tool length. CONSTITUTION: An installation part is formed so that tools 5 are installed around the periphery of the installation part of a rotor 11 by collecting the tools 5 almost without a clearance to a degree that a tool detaching exchanger is not accessible directly to the tools. Also provided is a moving unit 23 for moving each of or a plurality of the tools stored in the rotor 11 in radial direction over a range longer than the length of the tools 5. With such a structure, the tools 5 can be transported to specified positions, or held by the exchanger. Thus the number of tools 5 capable of being handled in a sufficiently short time and or for accurate positioning can be increased, and these tools 5 can be replaced by the exchanger. |
