ABSTRACT:
An edge miller for machining the edges of sheets advanced in motion relative thereto includes a milling unit supported for rotation therein and in turn supporting circular cutters for rotation relative thereto. The milling unit has bearings for each of the circular cutters supporting such rotation thereof, the bearings disposing the longitudinal cutter axes such that the axial and radial positions thereof are alternatively above and below the thickness centerline of the sheet and that each circular cutter has a cutting edge range between first and second cutting edge points. Machining forces between such cutting edge and the workpiece druing engagement produce a torque for rotating said circular cutter.
