    Abstract: Apparatus for machining parts, such as pistons, comprising a main spindle having an axis, a tool holding head movably mounted on one end of the spindle, a plurality of tools mounted in a circular formation on the head at positions spaced radially outwardly from the axis and a cross slide for moving the head transversely of the axis so that the tools thereon are movable between concentric and eccentric positions relative to the spindle axis. When the tools are in their concentric positions, a workpiece can be centered on the spindle axis in a clearance relation with the tools. When the cross slide is actuated to move the tool head toward the eccentric position, one of the tools is moved into machining engagement with the workpiece. The tool head is rotatable on the spindle to index the tools and is readily removable from the spindle for tool replacement purposes.
