Abstract: A method for machining a counterbore in a machining component is provided. The method includes positioning a machining component with respect to a machining tool, the positioning of the machining component based on geometric specifications of the counterbore. The machining tool includes a boring bar, the boring bar angled based on the geometric specifications of the counterbore. The method further includes, with the head traversed through the bore, repositioning one of the machining component or the tool such that the cutting element comes in contact with the second side of the machining component and, with the cutting element in contact with the second side of the machining component, rotating at least one of the tool and the machining component.

Abstract: A tool unit for performing a chamfering operation on a workpiece is disclosed. The tool unit includes a body, a plunger, at least one insert holder, and at least one cutter insert. The body includes a bore, and the plunger is movably positioned within the bore. The insert holder is coupled to the body and is in engagement with the plunger. The cutter insert is coupled to the at least one insert holder. The cutter insert includes a cutting edge adapted to be positioned at a cutting angle relative to the workpiece, and the cutting angle is varied relative to the workpiece upon a movement of the plunger within the bore.

Abstract: A runout calibrator for use in measuring runout of a spindle of a machine tool using at least one hydrodynamic bearing includes a head assembly with a shaft adapted at a first end for mounting in a chuck of the machine tool and a head mounted to a second end of the shaft. The head has a reflective surface and at least one line of symmetry coincident with the centerline of the shaft. The runout calibrator also includes a sensor assembly with one or more optical sensors mounted orthogonal to each other for measuring a distance between each of the one or more sensors and the head.
