Combination router-end mill cutter tool, edger with combination tool, and method of edging eyeglass lenses

An edger for shaping an edge of an eyeglass lens, comprising:

• a base plate;
• a first table secured to said base plate and moveable in a first direction, and a first drive motor for controllably moving said first table in said first direction;
• a second tables secured to said first table and moveable in a second direction perpendicular to said first direction, and a second drive motor for controllably moving said second table in said second direction;
• a lens clamping and rotating assembly secured to said second table and moveable therewith, said rotating assembly for controllably rotating a lens about a first axis extending generally parallel to said first direction and perpendicular to said second direction;
• a router tool mounted said base plate, said router tool rotatable on a second axis parallel to said first axis and said tool comprising a longitudinally extending body rotatable on the axis thereof, said body having a proximal portion and a distal portion, a first cutter extending axially and radially from said distal portion, said first cutter having a first blade for shaping an edge of a lens, said distal portion having a first diameter defined by said first blade, and a second cutter secured to and extending coaxially from said distal portion and rotatable therewith, said second cutter having a second blade for shaping the edge of the lens, said second cutter having a second diameter less than said first diameter;
• and
• a high-speed motor for rotating said tool at a speed of up to about 20,000 RPM.
