摘要
采用半人工热电偶法和人工热电偶法对硬质合金YG6和YT30平面磨削的温度场进行了实验研究。实验表明：距磨削表面越远，其磨削的温度的峰值越来越远高热源。YG6的导热性要优于YT30。YG6在磨削区的温度分布梯度较小，而YT30的高温层只集中在磨削表层附近。
In this paper,grinding temperatures field of cemented carbide YG6 and YT30 are measured and discussed in surfacegrinding using two kinds of the thermocouple techniques,The experiments proved that the more far leave the grinding sur-face,the more close the back of heat flux for the peak va1ue of grinding ternperature,The heat conduction property of YG6is better than YT30,the temperature,distribution gradient of YG6 is smal1 in grinding,and high temperature layer of YT3Oon1y concentrate nearby grinding surface.
