Working Principle: The counterbore is machined to the preset depth by the simultaneous application of both a rotary and vertical or horizontal feed motion to the carbide cutting insert. While the cutting insert rotates in a circle around the counterbore, a feed gear mechanism ensures a continuous feed motion. The lathe-type refacing action provides smooth and closely fitting contact surfaces for oversize valve seat rings. Features: The motor drive unit of the VD4HD-ADM is identical with the motor drive unit of the VD4HD Valve Seat Refacing Machine and, therefore, is only required, if no VD4HD is at hand. Two types of exchangeable boring gear heads are available. The standard AV boring head is provided with a vertical slide for counterboring. The optional AVH boring and facing head is provided with a vertical and a horizontal slide for counterboring and facing the bottom of the bore.
