Abstract

Vitrified diamond wheel as high grinding power, good corrosion resistance and self-sharpness is a desirable abrasive tool to difficult-to-machine materials. This study developed a fundamental vitrified bond prepared by sol–gel technique based on refractoriness, bending strength and coefficient of thermal expansion (CTE). The orthogonal experiment design and extreme difference analysis were used to optimize the material composition of Al2O3, SiO2, B2O3, and Na2O. The results show that the influence of Al2O3 and Na2O on refractoriness and CTE is more significant than that of other factors. The influence of Al2O3 and SiO2 on bending strength is more significant than that of other factors. Therefore, the optimal formulation of vitrified bond is recommended to being 80% for SiO2, 5% for B2O3, 10% for Na2O, and 5% for Al2O3, which present excellent performance for vitrified diamond wheels prepared by sol-gel. Besides, the conclusions drawn by orthogonal experiment are reconfirmed by vitrified bond prepared by sol-gel with varied components.
