<p>An orbital machining apparatus (10) for producing a cylindrical or conical hole in a workpiece by means of a cylindrical cutting tool (14). The apparatus comprises a radial offset mechanism configured for controlling the radial distance of the center axis (16) of the cutting tool (14) from a principal axis. The radial offset mechanism comprises an inner cylindrical body (24) having an eccentric cylindrical hole, said eccentric hole having a longitudinal center axis that is parallel to and radially offset from a longitudinal center axis of said inner body (24); and an outer cylindrical body (36) having an eccentric cylindrical hole, said eccentric hole of said outer body (36) having a longitudinal center axis (38) that is parallel to and radially offset from a longitudinal center axis of said outer body, said inner cylindrical body (24) being radially supported in said eccentric hole of the outer cylindrical body (36) and ro-tatable therein so as to adjust the radial distance of said center axis of the cutting tool (14) from said principal axis.</p> |
