中文摘要：

针对高效磨削中存在的磨削弧区热问题，有学者提出借鉴热工领域高效传热的热管技术来实现强化磨削弧区换热的构想。通过对热管砂轮结构的设计以及传热过程的理论分析，确定了影响热管砂轮传热性能的主要因素为工质种类、工质注液量和砂轮转速。并在搭建的传热性能试验平台上完成了热管砂轮基体的传热性能试验，探索了这些因素对热管砂轮传热性能的影响规律，确定了热管砂轮可用于缓进给深切磨削。在热管砂轮中注入18g蒸馏水进行了电镀CBN热管砂轮与无热管砂轮缓进给深切磨削高温合金GH4169的对比试验，通过对比两种砂轮磨削条件下磨削弧区的平均温度、工件表面质量、工件表层金相组织、显微硬度以及磨削后砂轮表面形貌等，证实了热管砂轮的确具有优良的强化换热效果，可在无热管砂轮磨削发生严重烧伤的情况下将磨削弧区的温度控制在60℃以下的较低水平。

英文摘要：

In order to figure out the burnout problem during grinding process, a novel method about enhancing heat transferring in the contact zone by incorporating a revolving heat pipe inside the wheel disk has been proposed. By designing the structure and analyzing the heat transfer process of heat pipe grinding wheel （HPGW）, factors as working fluid kind, fluid loading and rotating speed are determined to be the main factors that may affect its heat transfer capacity. Heat transfer analysis experiments were complemented on a self-designed experiment platform, on which the influences of different factors are investigated. According to the results of the heat transfer analysis experiments, a CBN HPGW injected with 18 g distilled water is fabricated and applied in creep feed grinding of Inconel 718. The results are compared with non-HPGW in terms of the average temperature in the contact zone, workpiece surface quality, microstructure and micro-hardness of the ground workpiece surface and the grinding wheel surface. Results show that the temperature in the contact zone can be controlled below 60℃ when using HPGW, while sever burnout happened when using non-HPGW at the same conditions, which confirmed the excellent heat transfer performance of HPGW.
