The article takes modified phenolic resin(PF),bismaleimide(BMI),and modi-fied phenolic resin(PF)/bismaleimide(BMI)blended resin as the research objects,and systematically compares and analyzes the properties of the three resins and their applica-tions in ultra-thin resin bonded cutting wheels.The results show that PF is better than BMI in terms of heat resistance and mechanical properties;PF is better than BMI in terms of cutting life for QFN materials when applied to ultra-thin grinding wheels;BMI is better than PF in terms of cutting quality for Al2 O3 materials when applied to ultra-thin grinding wheels;PF modified BMI can improve the forming accuracy of the ultra-thin resin bonded cutting grinding wheels.
