<p>A machine tool includes a spindle side position measuring unit (20) for measuring a spindle axial position (O) in a spindle radial direction relative to a first reference position (P1) and a tool side position measuring unit (30) for measuring the position of a tool post (7) relative to a second reference position (P2). The spindle side position measuring unit (20) includes a first stale (21), extending in the spindle radial direction and a first readout unit (22), and one of a base end portion of the first scale (21) and the first readout unit (22) is disposed in the vicinity of a spindle axis (O) and the other thereof is disposed at the first reference position (P1). The tool side position measuring unit (30) is such that one of a base end portion of a second scale (31) and a second readout unit (32) is disposed on the tool post (7) and the other thereof is disposed at the second reference position (P2).</p> |
