Laser processing of ultra-hard cutting materials

Ultra-hard cutting materials such as polycristalline diamond with binder phase (PCD) as well as CVD diamond are currently used in all areas of industrial production. Often the hardness of these cutting materials is necessary to enable the machining of advanced materials which are difficult to cut. The objective of the project presented in the paper is to make efficient techniques for processing ultra-hard cutting materials available by developing and applying an economical and environmentally friendly laser technology. The focus of the project lies on examining the interrelation between the laser beam and the cutting material in order to establish the technological basics of the laser processing of ultra-hard cutting materials. In addition, the defined processing of the surfaces and the edges of the tools shall optimize the tool characteristics. Based on the data gathered in these investigations, tools made from ultra-hard cutting materials are processed for cutting experiments. On the basis of the final cutting experiments the laser processing undertaken is evaluated. Entnommen aus <a_href="http://www.fiz-technik.de/db/b_tema.htm" target="_blank">TEMA</a>
