氧化锆陶瓷在汽车工业、电子工业、航空航天工业等领域的应用越来越多，但这种材料很难加工。因此，对可加工性的开发变得十分迫切，尤其是在珩磨领域，是汽车发动机开发中的一个紧迫问题。分析了珩磨棒安装角度对接触区应力分布的影响。

THE USE OF ZIRCONIA CERAMICS IS INCREASING IN THE AUTOMOBILE INDUSTRY, THE ELECTRONICS INDUSTRY, THE AEROSPACE INDUSTRY, ETC., BUT THIS MATERIAL IS DIFFICULT TO MACHINE. THUS, DEVELOPMENT FOR MACHINABILITY BECOMES PROMINANT AND, ESPECIALLY IN THE AREA OF HONING, IS AN URGENT PROBLEM IN DEVELOPMENT OF A CAR ENGINE. STRESS DISTRIBUTION OF A CONTACT ZONE BY THE SETTING ANGLE OF HONING STICK IS ANALYZED.
