Machining center

A machining center comprising:

• (A) a main shaft head including a main shaft on which a tool is attached and a main shaft rotating device that rotates the main shaft;
• (B) a head raising and lowering device that moves the main shaft head in a vertical direction;
• (C) a head moving device that moves the main shaft head in a horizontal plane by moving it in two perpendicular directions;
• (D) a work table that holds a work;
• and (E) a tool magazine for storing multiple tools equipped with multiple tool holders that each hold a tool to be attached to the main shaft, one of the multiple tools stored in the tool magazine being able to be automatically exchanged with the tool attached to the main shaft;
• a machine main body, an upper section of which supports the head moving device and the head raising and lowering device, the tool magazine being stored inside the machine main body, and
• a magazine moving device configured to move the tool magazine such that, during tool exchange, the tool magazine is advanced to protrude from a side of the machine main body, so that the tool holder used for exchange from the multiple tool holders is positioned inside the movement range of the main shaft by the head moving device, and wherein the entire tool magazine is able to be moved beyond the movement range of the tool magazine by the magazine moving device to a position outside of the machine main body and detached from the machine main body.
