Method of cutting super-hard materials using an electron beam and a range of beam scanning velocities

摘要

A 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−1 to cut the super-hard material (8).
