Method for preparing ultra hard cutting material e.g. monocrystalline diamond used for cutting tool, involves irradiating electron beam on ultra hard cutting material

摘要

The method involves irradiating electron beam on ultra hard cutting material. The electron beams are combined by focusing device and the combined beams are provided to the ultra hard cutting material. The irradiation of the electron beams is performed at specific operating point. The power density of the electron beams is set to 108 W/cm 2. An independent claim is included for ultra hard cutting material.
