人造刚玉,人造金刚砂;
The paper analyses the influence of the final process, i.e. grinding, of harder materials on the roughness of surface, including the roughness of surface processed by artificial diamond grinding wheel and artificial corundum grinding wheel and comparison of parameters of support curves.
分析了较硬材料的最终加工工序磨削对其表面粗糙度的影响,包括人造金刚石砂轮与人造刚玉砂轮所加工的表面粗糙度和支承曲线参数值的对比。
