Abstract
A machining center includes a rotatable tool magazine () arranged above a work space (WS) facing a spindle () tilted so that the spindle side becomes lower and having a plurality of grippers () for holding tools () in a circumferential direction, and a shutter () arranged below the tool magazine () to be able to open and close facing the spindle side. The tool magazine () has a tool-free area (AR) where there are no grippers () at a part of the circumferential direction and a tool-holding area (ARA) where there are grippers () at another part of the circumferential direction. The tool magazine () is controlled in rotation so that when the shutter () is closed, the tool-free area (AR) moves to the spindle side while when the shutter () is open, the tool-holding area (AR) moves to the spindle side.
