摘　　要：目前钢轨打磨使用的主要是树脂砂轮,具有材料去除率低、磨削温度高等问题。因此,利用钎焊超硬磨料技术研制新型陶瓷–金属结合剂CBN磨具,并对比陶瓷–金属CBN结块和树脂锆刚玉结块在相同条件下的磨削性能,如材料去除率、磨屑分布和磨削温度等。试验结果表明:相比于树脂锆刚玉结块,陶瓷–金属结合剂CBN结块的材料去除率可提高124%,磨削温度峰值可降低15~50℃。Resin bond wheels are mainly used for rail grinding,which have problems such as low material removal rate and high grinding temperature.Therefore,a new ceramic-metal bond CBN block was developed by using brazed super-hard abrasive technology.The grinding performance of ceramic-metal bond CBN block and resin zircon corundum was studied,such as material removal rate,chip distribution and grinding temperature.Results show that compared with the resin zirconium corundum,the ceramic-metal bond CBN block has a 124%higher material removal rate and a 15~50℃lower grinding temperature peak.
