摘　　要：选取了一种成本较低的超细铜钴铁合金粉去替代用于高硬瓷砖湿切的金刚石圆锯片刀头结合剂中的钴粉,研究其对锯片性能的影响。研究发现,替代后,产品切速有了一定的下降,但当钴粉价格较高,超过400元/kg时,产品的性价比有了较明显的提升,且替代比例越高,性价比优势越明显。该合金粉在钴粉价格高时性价比高,更适宜通用金刚石工具;钴粉性能有优势,更适宜专业金刚石工具。A lower cost superfine copper-cobalt-iron alloy powder was selected to replace the cobalt powder in the binder of diamond circular saw blade for wet cutting of high hard tile, and the influence on the performance of the saw blade was studied. The results showed that there was a certain decrease of the cutting speed of the product after substitution, but when the price of cobalt powder was higher than 400 yuan/kg, the cost performance of the product was significantly improved. the higher the substitution ratio, the more obvious the cost performance advantage. The superfine CuCoFe alloy powder is more suitable for general diamond tools when the price of cobalt powder is high. Cobalt powder has advantages in performance and is more suitable for professional diamond tools.
