ABSTRACT:
A tool coupling arrangement is disclosed for a tooling assembly (10) adapted for automatic tool insertion into a spindle assembly (12), the tooling assembly (10) having an axially moveable element (20) for causing movement independently of the spindle assembly (12). In the particular disclosed applications, a pair of cutting tools (14, 16) are provided to simultaneously machine concentric features on a workpiece (8), disclosed as a valve stem guide bore (9) and valve seat (7) of an engine cylinder head. A first coupling arrangement secures this tooling assembly (10) after it is inserted within the spindle assembly (12), while a second coupling arrangement automatically couples the separately moveable element (20) to an inner draw bar (84) of the spindle assembly (12). The second coupling arrangement couples the inner draw bar (84) to the independently moveable element (20) by limited rotation thereof after limited axial advance to enable continued axial advancing of element (20) by movement of the inner draw bar (84), independently of the spindle assembly (12).
