| description | To improve the grinding efficiency and service life of rail grinding wheels, a surface porous CBN/Cu-Sn-Zn compact abrasive is prepared. This work discussed the performance of Cu-Sn metal bond used for preparing agglomerated abrasives, the influence of pore structure on CBN agglomerated abrasive and the effect of agglomerated abrasive on the structural strength of grinding wheel. The grinding effect of grinding wheel before and after compound abrasive addition was evaluated by rail grinding experiment. The results show that the best porous CBN agglomerated abrasive sample has a flexural strength of 78.5 MPa, an impact strength of 5.5 kJ/m2, and a surface porosity of 30%～40%. The combined use of abrasive can effectively combine the high hardness of CBN with the good impact toughness of zirconium corundum. The grinding efficiency and grinding quality of rail grinding wheels with 20% volume concentration accumulated abrasives are further improved. |
