Abstract
The present invention provides a machine tool capable of detecting loosening of the jib's fixation of the feed table to the base with a simple configuration. [Solution] The machine tool comprises a base (21) having a pedestal (56A), a movable body (31) having a feed table (36A) that slides against the pedestal (56A) and is movable relative to the base (21), a jib (38) that fixes the feed table (36A) to the pedestal (56A), a scale section (72) provided on the base (21), a head section (73) provided on the movable body (31) that faces the scale section (72) with a gap (74) between them, a linear scale (71) for detecting the position of the movable body (31), and a control device (81) that detects loosening of the fixation of the feed table (36A) to the pedestal (56A) based on a signal from the linear scale (71).
