The performance of three kinds of low-temperature ceramic binding agent Abstract comprehensive study found: refractoriness to 775 oC, flowability l10% ~ 130%, a low temperature coefficient of linear expansion of the vitrified bond 5.79 × 1 0-6oC-1 is The comprehensive performance of V2 is excellent. It was found by differential thermal analysis that there was no significant crystal phase generation of the binder V2 in the measurement temperature range. With CBN abrasive samples prepared with a binding agent V2 800 oC after calcination, the bending strength of the grinding wheel to achieve optimum sample value 67.5MPa. The prepared grinding disc has good sharpness during grinding, less trimming in the middle of grinding, and high durability of the grinding disc. The morphology of the grinding surface of the CBN grinding disc after grinding was observed by scanning electron microscopy (SEM), which showed that the bonding agent had firm adhesion to the abrasive grains and uniform cross-section.
