Article Preview

To meet the requirements of super-high speed vitrified bond of CBN grinding wheel that should be low-melting, high strength and multi-foams, performance of nano-ceramic bond were researched in this paper. Four types of bond which major glass components was R2O+RO-B2O3- -Al2O3-SiO2 have been compounded with pure raw chemical materials. In order to improve the strength of bond, nano-materials were added into formulations of the vitrified bond. And experiments results showed that compared with traditional vitrified bond the new nano-ceramic bond had a significant advantage at its refractoriness, expansion coefficient, surface morphology and bending strength. Especially, the bending strength of 4# nano-ceramic bond had reached to 83.75 MPa and its refractoriness was 790 °C. It proved that 4# nano-ceramic bond was more suitable for super-high speed CBN grinding wheel.
