The research on the improved CMG tool for Al2O3 ceramic

摘要：

　　A new D/SiO2 CMG tool for Al2O3 ceramic process was developed by adding some diamond abrasive into SiO2 CMG tool.The solid state reaction between the CMG tool and Al2O3ceramic played a key role for achieving ultra-precision,high efficiency and low damage.Three kinds of formulations for the D/SiO2 tool were tested and evaluated.The material removal rate(MRR) of Al2O3 ceramic mainly depended on the content of diamond abrasive.In contrast with the corresponding SiO2 tool,the D/SiO2 tool,which had minimal content of diamond abrasive,could achieve a minimal Ra and better MRR.The enhanced mechanical removal action made the MRR improve nearly twice times,and the process surface roughness of Al2O3 ceramic specimen using the D/SiO2 tool kept almost same value as using the SiO2 tool without surface damage.Thus the D/SiO2tool is more suitable for process of Al2O3 ceramic workpieces.
