Abstract
In a work transfer method in a machine tool with a movable spindle, a machined work transfer portion for laying a machined work on a first pallet and for transferring the work is disposed in an upper stage or a lower stage of a non-machined work transfer portion for laying a non-machined work on a second pallet and for transferring the work. Then, the non-machined work pallet is moved between a non-machined work receiving position and a work loading position. The machined work pallet is moved between a machined work sending position and a work unloading position. Thus, the work is received or sent between a chuck and a work transfer apparatus.
