To provide a machine tool capable of processing a work to have a required thickness based on a simple structure without adjusting a distance itself between both cutting tools. A machine tool includes: a spindle rotating around a Z-axis extending in a horizontal direction; a tool post disposed in a movable manner in the Z-axis direction and an X-axis direction orthogonal to the Z-axis direction and in a pivotable manner around a B-axis orthogonal to a plane face containing the X-axis and the Z-axis; a tool having a pair of tips disposed to have a predetermined interval therebetween and fitted to said tool post; and a tool post control unit adjusting a pivot angle of said tool post so that an angle alpha between a straight line connecting the pair of tips and the Z-axis comes to an angle corresponding to a finished thickness of a work.
