Abstract
To provide a machine tool that can be downsized and allows easy expansion of a tool magazine.SOLUTION: A machine tool 1 comprises: a tool spindle 4 to which a tool T for machining a workpiece W is replaceably mounted; a tool storage device 5 having a standard tool magazine 52S in which a plurality of tools T mounted on the tool spindle 4 are stored; and a tool exchange device 6 having a tool exchange arm 63 that grips the tool T and a first moving mechanism 61 that moves the tool exchange arm 63 in a +Z direction using a Z-axis rack 613 and a pinion 6151 meshed with the Z-axis rack 613. The tool exchange device 6 has a thin plate portion 6111 for attaching an extension member 61A for extending a movement stroke of the tool exchange arm 63 in the +Z direction. The tool storage device 5 has a rotation shaft projection part 532B for attaching an additional tool magazine 52A which increases the number of stored tools T, on a +Z direction side relative to the standard tool magazine 52S.SELECTED DRAWING: Figure 1
