Abstract: An X-Y movement mechanism includes a fixed base having a first surface and a movable member having a second surface. The movable member is disposed for movement relative to the fixed base with the second surface being parallel with and facing toward the first surface. At least a first groove in the first surface extends in an X direction and a second groove in the second surface extends in a Y direction. The X direction is different from and at an angle with respect to the Y direction and both are parallel to the first surface and to the second surface. The first and second grooves respectively have overlying regions when the movable member is disposed for movement relative to the fixed base. An X-Y guide element has a first half and a second half. The first half is disposed in the first groove for sliding, non-rotating relative movement therebetween in the X direction. The second half is disposed in the second groove for sliding, non-rotating relative movement therebetween in the Y direction.

Abstract: A vertical boring machine is for boring or facing a circular region of a component having a central axis and includes a horizontal support for supporting the component with the central axis extending in a vertical direction. A tool support is disposed for rotation at the central axis to extend in said vertical direction. The tool support includes a tool head extending radially outwardly of the central axis which is configured for controlled radial movement and for controlled axial movement. The vertical boring machine preferably includes a mechanism for selectively moving the base of the tool support in an X direction and in a Y direction relative to the horizontal support aligning the tool support with the central axis. The X direction and Y direction are in a horizontal plane and perpendicular to each other.
