A machine tool centre has a frame with a tool arm and spindle that moves axially from a holding point to a machining point. The spindle is operated by a control system. The tool centre further has a work-piece holder that operates in conjunction with a work piece changing unit and actuators. Operation of the work piece holder and work piece changing unit are coordinated by the control system.
