METHOD OF CUTTING SUPER HARD MATERIALS USING AN ELECTRON BEAM AND A RANGE OF BEAM SCANNING VELOCITIES

摘要

1A method of cutting a super hard material (8) using an electron beam (6) wherein the electron beam (6) is directed onto a surface of the super hard material (8) and moved relative to the surface such that the electron beam (6) moves across the surface of the super hard material (8) at an electron beam scanning velocity in a range 100 to 5000 mms to cut the super hard material (8).
