    摘要: A machine adjustable boring bar assembly is disclosed for use with a rotatable spindle of a machine tool which accepts interchangeable tools. This assembly includes an elongated boring bar body interchangeably mounted in a rotatable machine tool spindle and with a transversely movable tool mount on the distal end of the boring bar body. First and second external sleeves are rotatably mounted on the body with a motion transmission connection between the sleeves and a tool mount to establish transverse tool adjustment upon selectively holding stationary or rotating in selected directions the two sleeves by means of pinion reaction members driven by motors. The motion transmission connection includes planetary gearing for a wide range of rates of radial motion of the tool mount so that this adjustment may be effected during the time when the boring bar assembly is mounted in the rotatable machine tool spindle and actually cutting a workpiece for step turning, undercutting, or taper cutting. The foregoing abstract is merely a resume of one general application, is not a complete discussion of all principles of operation or applications, and is not to be construed as a limitation on the scope of the claimed subject matter.

    摘要: An apparatus and method is provided for an air bearing support of a rotatable tooling bar, such as a boring bar. One or two mandrels may be provided for this tooling bar to form a complete mandrel assembly with the tooling bar. An air pressure expansible collet is provided on each mandrel so that each may be clamped within a clamping aperture, such as an aperture on the workpiece itself. Air under pressure is supplied to the two mandrels simultaneously to accomplish, first, an air bearing centering of each mandrel around the tooling bar as a guide; second, an expansion of the collet on each mandrel for clamping of each mandrel within the clamping apertures; and, third, provision of an air bearing support and centering of the tooling bar within the two mandrels during machining for precise machining of the workpiece by the continued air supply. The foregoing abstract is merely a resume of one general application, is not a complete discussion of all principles of operation or applications, and is not to be construed as a limitation on the scope of the claimed subject matter.
