硬质合金磨削温度的实验研究

THE EXPERIMENT-INVESTIGATION OF GRINDING TEMPERATURES FOR CEMENTED CARBIDE

采用半人工和人工热电偶法，对硬质合金YG6和YT30平面磨削的磨削温度进行了实验研究。并对磨削参数与磨削温度的关系，进行了理论分析及实验验证。结果表明：磨削深度和工作台速度增加，磨削温度升高，但工作台速度的改变，对磨削温度的影响较小．

In this paper,grinding temperatures of cemented carbide YG6 and YT30 are studied in surface grinding using two kinds of the tbermocouple techniques,tbe relationship between grinding parameters and grinding temperarures are analyzed theo retically and proved with experhaents. The experiment proved that grinding temperatures increase with the increase of actual grinding depth and table speed,but the grboing temperatures have only smaller change when table speed in changed.
