Abstract
A machine tool (10) with a rotating cutting tool (24) has a spindle assembly (20,48) mounted for rotation in a longitudinally movable headstock (18). The spindle assembly includes a spindle (48), driven by a motor (50) and an integral machining head (20) having a rotatably mounted drive screw (62). The drive screw carries a radially positionable follower (72) to which is connected a tool block (22) to define a radial slide for supporting the cutting tool. A drive shaft (82) extending through the spindle is in driving engagement with the drive screw such that rotation of the drive shaft relative to the spindle produces rotation of the drive screw and consequential radial movement of the follower and tool block. A motor (76) mounted on the spindle for rotation with the spindle is connected to the drive shaft for rotating it either a clockwise or counterclockwise sense to produce radial movement of the follower and tool block. A counterbalance block (70) is in threaded engagement with a threaded shaft (142) mounted in the machining head in driving connection with the drive shaft for providing dynamic balance. A tool changer assembly (38) is secured to a floor mounted support (46) for changing tools in the tool block.
