MACHINE TOOL

摘要

A machine tool in which machining precision can be prevented from lowering even in a case where a column deforms due to movement of a main spindle to each axial direction. A machine tool (1) for machining a work (W) by relatively moving a tool (T) and the work (W) comprises a saddle (16) for rotatably supporting a main spindle (19) to which the tool (T) is removably attached, a column (14) movably provided and movably supporting the saddle (16), and a column deformation detector (30) for detecting deformation of the column (14) caused by movement of at least one of the saddle (16) and the column (14), wherein movement of at least one of the tool (T) and the work (W) is corrected based on the detection result of the column deformation detector (30).
