工程陶瓷的磨削钻孔及表面形成机理
Drilling and forming mechanisms of ground surfaces in engineering ceramics
摘要
Abstract
The specially sintered diamond bits were developed for drilling engineering ceramics with composition (vol%) of bond matrix being 48% Cu, 30% Co, 6% Ni, 5% WC, 5% Ti, 4% Sn and 2% Cr. In view of the abrasive machining characteristics, the calculation expression of mean load per diamond on the lip face were set up, and accordingly the forming mechanism of ceramic ground surface was presented. Through SEM observations of ceramic ground surfaces, the material removal mechanisms were analyzed and verified. The results show that most of ceramic ground surfaces are formed through brittle fracture and few through ductile deformation.关键词
