摘要
通过切割试验,研究并分析了添加不同参数铜锡合金粉制成砂轮的切割性能。通过SEM、XRD分析了添加不同参数铜锡合金粉制成的树脂结合剂金刚石切割砂轮切割后的表面形貌和物相。试验结果表明:添加不同量及添加不同粒度铜锡合金粉制成砂轮的切割试验中,铜锡合金粉体积分数为15%、粒度为40μm左右时,砂轮的耐用度最好。不同参数铜锡合金粉制成的树脂金刚石砂轮对其切割性能都有影响,其中以铜锡合金粉添加量、铜锡合金粉中铜锡比例对砂轮的切割性能影响最为明显。
The cutting performances of the resin-bonded diamond wheel made with addition of different parametered copper tin alloy powder were studied through cutting test.The surface morphology and phases of the resin-bonded cutting diamond wheel after cutting were analyzed by scanning electron microscope(SEM) and X-ray diffraction,respectively.The results showed that when the copper-tin alloy powder volume fraction was 15% and particle size was 40 μm,the best tool life of resin-bonded diamond wheel could be obtained.The cutting performances of resin-bonded diamond wheel were influenced by different parameters of copper-tin alloy powder,in which copper-tin alloy additive amount and copper/tin ratio had greater influences on the durability of diamond cutting wheel.
