Abstract
Section titled āAbstractāChemical vapor deposition (CVD) diamond coated<br> cutting tool has excellent cutting performance, it is the most ideal tool<br> for the processing of nonferrous metals and alloys, composites,<br> nonmetallic materials and other difficult-to-machine materials<br> efficiently and accurately. Depositing CVD diamond coating on the<br> cemented carbide with high cobalt content can improve its toughness<br> and strength, therefore, it is very important to research on the<br> preparation technology and cutting properties of CVD diamond coated<br> cemented carbide cutting tool with high cobalt content. The<br> preparation technology of boron-doped diamond (BDD) coating has<br> been studied and the coated drills were prepared. BDD coating were<br> deposited on the drills by using the optimized parameters and the SEM<br> results show that there are no cracks or collapses in the coating.<br> Cutting tests with the prepared drills against the silumin and aluminum<br> base printed circuit board (PCB) have been studied. The results show<br> that the wear amount of the coated drill is small and the machined<br> surface has a better precision. The coating does not come off during<br> the test, which shows good adhesion and cutting performance of the<br> drill.
