摘　　要：以某微晶玻璃为结合剂,制备了不同辅助磨料含量金刚石试样。通过对试样的抗弯强度测试,研究了不同辅助磨料含量对金刚石试样力学性能的影响。通过金刚石试样对YG8立方块的磨削实验,研究了在不同辅助磨料含量条件下试样对硬质合金在加工性能上的影响。实验结果表明,在设计范围内,试样的抗弯强度随着辅助磨料含量的增大而减小。在磨削YG8时,0.12 mm/min的进刀速度下,磨耗比随着辅助磨料含量的增大而呈现升高—降低—升高的变化趋势;0.3 mm/min的进刀速度下,磨耗比随着辅助磨料含量的增大呈现先升高后降低的趋势。A microcrystalline glass bonder is used as the experimental binder,diamond samples with different content of auxiliary abrasives are prepared.The effect of different contents of auxiliary abrasives on the mechanics of diamond samples is studied by testing the flexural strength of the samples.The grinding experiment of diamond sample and YG8 cube is carried out,the influence of samples on the machining properties of cemented carbide with different contents of auxiliary abrasives is studied.The experimental result shows that the bending strength of the sample decreases with the increase of auxiliary abrasive content within the design range.In the grinding process of YG8,for the feeding speed of 0.12mm/s,the wear ratio increases firstly,then decreases and then increases with the increase of auxiliary abrasive content.For the feeding speed of 0.3mm/s,the wear ratio increases firstly and then decreases with the increase of auxiliary abrasive content.
