Study on high-performance isotropic graphite milling for new CVD diamond coated tool
In this paper,the new CVD diamond composite coating tool milling experiment of the self-developed high density and high strength isotropic graphite material was carried out,and the cutting performance of the new CVD diamond composite coating tool and PCD tool were compared.The test results show that the flank wear has exceeded the standard 0.3 mm after the PCD tool milling processing 25 min.,while the flank wear is only 0.25 mm after the new CVD diamond composite coating tool processing to 45 min.,which shows that the new CVD diamond composite coating tool is of good wear and service life in high-speed milling graphite,and can adapt to the processing requirement of high performance isotropic graphite.It was also found that the graphite surface quality of the new CVD diamond composite coating tool was inferior to PCD tool in the initial milling stage,but the machining surface quality was better than PCD tool in the longer processing time.
