Abstract
A workpiece supply device is provided that is capable of supplying a workpiece to be machined next in a supplying area of the workpiece outside a machining area while the machining area is closed to control scattering of cutting fluid from the machining area during the machining of the workpiece. A machine tool includes a machining room of the workpiece, a loader room, a dividing wall having an opening part, a main spindle, a workpiece supply device, a delivery device, and an ejection device. The workpiece supply device includes a workpiece holder, a movement mechanism, a cover member, and a coil spring. The coil spring biases the cover member to close the opening part by the cover member such that the workpiece holder holds the workpiece in the loader room during the machining of the workpiece in the machining room.
