ABSTRACT:
A vertical machine tool with a movable main spindle has a headstock for supporting a spindle having an axis in a vertical direction. A work feeder gives and takes a work between the work feeder and a chuck. The work feeder includes a work feeder frame provided in the vicinity of a machine body, a swivel member driven by a driving means for swivelling, a plurality of pallets mounted on the swivel member, and a supporting device disposed in a work receipt/release position where the pallet is positioned for receiving/releasing the work between the pallet and the chuck. The supporting device supports the pallet, positioned in the work receipt/release position, movably up and down in the direction of the axis of the spindle. The receipt/release of the work may be performed under the condition that the work is kept depressed to the chuck.
