Article Preview

Blades are the key parts of the turbine, which usually use materials such as 1Cr13 stainless steel. These materials are of high strength, great toughness, and good thermo hardening, but the process is difficult. Abrasive belt grinding has good grinding performance. Grinding tests of three kinds of abrasive belts were carried out on 1Cr13 stainless steel; the relationship between the material removal rate and the species, such as abrasive belt type, belt speed, the normal grinding force, and grinding fluid, was studied; after the belt grinding, the microscopic morphology of the surface was analyzed by SEM, and it revealed that the differences of the micro structure and basic wear law of different abrasives. The results show that in the process of abrasive belt grinding, the ceramic abrasive belt has the highest material removal rate. The material removal rate of alumina and zirconium corundum abrasive belt reached the maximum when Vs is about 25m/s or so, and ceramic abrasive belt is stable to maintain high material removal rate when Vs is at the speed range of 28 to 32m/s. The material removal rate can be improved several times when using grinding fluid of butter.
