ABSTRACT:
The lapping of a facet into a conical diamond tip brazed to a metallic (titanium) shank is controlled by sensing an electrical pulse generated when the diamond facet is enlarged in the vicinity of the titanium shank. A pulse detecting circuit responding to the pulse generates a control signal for energizing a mechanism to lift the stylus from the lapping scaife to cease lapping.
