Patent ID: 7074116

Claim:
A tool for machining an interior surface of a bore, the tool comprising: a tool shaft adapted to perform a rotational movement around an axis of said tool shaft and an oscillating movement in an axial direction of said tool shaft; a honing tool mounted on said tool shaft; wherein said honing tool comprises honing slats moveable in a radial direction of said tool shaft; wherein said honing tool further comprises means for pressing said honing slats against an interior surface of a bore for performing a honing operation on the interior surface of the bore; a deburring tool mounted on said tool shaft at an axial spacing from said honing tool; wherein said deburring tool has a surface slanted at a slant angle relative to said axis of said tool shaft for deburring an edge of the bore which edge adjoins a workpiece surface surrounding the bore; wherein said honing tool is adapted to move for each honing stroke between a lower honing position and an upper honing position in said axial direction, wherein a spacing between a lower edge of said honing tool and a lower edge of said deburring tool in said axial direction is greater than a spacing of said lower edge of said honing tool to the workpiece surface when said honing tool is in said lower honing position such that said lower edge of said honing tool is in a position below said lower honing position when said deburring tool contacts the workpiece surface at the edge of the bore.
