Precision grinding of cemented carbide ball valves by resin diamond wheels with different pore-forming agents

  • 摘要: 为改善硬质合金球阀的加工效果,在树脂金刚石砂轮中引入造孔剂,对其力学性能、微观形貌及磨削性能进行分析,研究空心玻璃球和塑料球造孔剂对树脂金刚石砂轮性能的影响。结果表明:随着造孔剂体积分数增加,树脂砂轮的抗折强度逐渐下降,且2种造孔剂对抗折强度的影响基本一致;砂轮的硬度随造孔剂体积分数的增加亦逐渐下降,但空心玻璃球造孔剂对砂轮硬度的影响显著大于塑料球的;加入造孔剂明显提升了砂轮的锋利性,空心玻璃球体造孔剂体积分数为15%和塑料球造孔剂体积分数为20%的砂轮综合性能最好,且后者的综合性能优于前者的。
