Abstract
An automatic lathe includes a positioning block that positions a rod material, the rod material projecting from a main spindle contacting the positioning block, and a sensor that moves in a direction intersecting with a shaft center C direction of the main spindle to detect a cut off condition of the rod material. The positioning block includes a groove that allows movement of the sensor, and moves in the same direction as a movement direction of the sensor between a position that contacts the rod material and a position that has no contact with the rod material. The sensor moves along the path in the position that has no contact with the rod material.
Claims5
A machine tool comprising:
- a positioning member that positions a rod material, the rod material that projects from a main spindle contacts the positioning member to be positioned;
- and
- a detector that moves in a direction intersecting with an axis direction of the main spindle to detect a cut off condition of the rod material,
- wherein the positioning member includes a path that allows movement of the detector, and moves in a same direction as a movement direction of the detector between a position that contacts the rod material and a position that has no contact with the rod material, and
- the detector moves along the path when the positioning member moves to the position that has no contact with the rod material.
