ABSTRACT A system for automatic radial adjustment of a boring tool in a machine tool spindle to accurately size a bore in a workpiece within extremely close tolerances over a wide range of bore sizes. The system includes a boring tool mounting a toolholder and cutter and a precision adjusting means for setting the radial position of same; an adjusting actuator adapted for operative engagement with the precision adjusting means; a probe, gage and other means which measures the size of a preliminary bore in the workpiece; an adjusting control operatively connected to the actuator for altering the radial position of the cutter and toolholder; and means for setting the adjusting control to effect an adjustment in the radial position of the workholder and cutter by an amount proportional to the deviation between the size of the preliminary bore and the size of the final bore to be generated in the workpiece. The system may be used in any manual or numerically controlled machine capable of performing boring operations.
