Zusammenfassung:	An automatically adjustable boring and turning quill assembly for a boring machine and including an adjustable eccentric sleeve member for moving or turning the boring bar radially toward and away from the workpiece and a piston which upon axial movement produces adjustment of the sleeve member. Fine adjustment to compensate for wear of the boring bar is provided by a stepping motor which actuates an adjustable stop for the piston.
