| 摘 要： | 在刀具前刀面月牙洼磨损区域加工装填MoS2固体润滑剂的微孔,制备了一种镶嵌固体润滑剂的自润滑刀具(SLT-1),并与前刀面有孔但无固体润滑剂的刀具(SLT-2)以及传统刀具(SLT-3)进行切削对比试验.用TH5104红外热像仪测试了3种刀具切削45号淬火钢的切削温度变化规律.结果表明:SLT-1自润滑刀具的切削温度明显降低,比传统刀具SLT-3降低15%～20%,SLT-2刀具比SLT-3降低5%～10%.通过切削温度理论分析表明,由于自润滑刀具SLT-1在前刀面形成润滑膜,降低了前刀面剪切应力以及减少了刀屑接触面积,使得切削温度显著降低.

| Abstract: | Microholes were made on the rake of the cemented carbide tools and MoS2 solid lubricants were embedded into the microholes to form self-lubricated tools(SLT-1).Dry machining tests on hardened steel were carried out with the self-lubricated tool,the tool with microholes on the rake without solid lubricants(SLT-2) and the conventional tool(SLT-3).The variation of cutting temperature for 45# hardened steel cutting with the three cutting tools were tested by the TH5104 thermo tracer.The result shows that the cu... |
