Abstract
In a vertical machining center, a spindle head is movable in three mutually transverse axes directions relative to a workpiece and a table is arranged below. A vertical stocker is disposed in the vicinity of a machining area and stocks the bar workpiece in a vertical direction. A hand portion which grips and releases the bar workpiece is provided on the spindle head. The spindle head moves between the stocker and the table so that the hand portion transfers the bar workpiece and performs putting and removing the bar workpiece to the stocker and a chuck of the table, respectively.
