Claims

[Scope of utility model registration request]

A spindle carrier that holds the tip of a drive shaft rotatably at one end and is rotatably indexed concentrically with the main drive shaft, and a spindle carrier that surrounds the main drive shaft parallel to the main drive shaft. A plurality of workpiece spindles are rotatably attached to the carrier in a penetrating state, and each of the workpieces to be turned is removably attached to the other end, one end side of these workpiece spindles, and the tip of the drive spindle. a power transmission means for transmitting the rotation of the drive main shaft to the work main shaft; a cooling fan built into the other end of the spindle carrier so as to be rotatable; and a cooling fan formed in the spindle carrier. 1. A multi-spindle automatic lathe comprising: a cooling passage for guiding cooling gas from the cooling fan to a spindle portion disposed at least on the other end side of the spindle carrier of the work spindle.
