摘　　要：为了提高16Cr3NiWMoVNbE钢的使用性能,通常需要进行碳氮共渗表面硬化处理。为了解决16Cr3NiWMoVNbE钢碳氮共渗层易出现磨削烧伤、裂纹等问题,开展了白刚玉砂轮磨削力试验。首先,分析了磨削3要素(磨削速度、工件进给速度和磨削切深)对磨削力的影响规律;其次,分析了白刚玉砂轮磨粒大小、砂轮硬度和气孔率对磨削力的影响规律;最后,分析了磨削3要素对工件表面形貌的影响规律。结果表明,随着磨削切深的增大,磨削力增大;随着工件进给速度的增大,磨削力增大;随着砂轮速度的增大,磨削力减小。随着砂轮磨粒的增大,磨削力减小;为了减小磨削力、提高砂轮切削性能,白刚玉砂轮适合选用J级硬度和4号组织号。减小磨削切深、工件进给速度,增大砂轮速度,可改善工件表面形貌。In order to improve 16Cr3NiWMoVNbE steel's service permance,it is subjected to carbonitriding surface hardening treatment.In order to solve the problems of grinding burns and cracks in the carbonitriding layer of 16Cr3NiWMoVNbE steel,the grinding force test of white corundum grinding wheel was carried out.Firstly,the influence laws of three grinding factors(grinding speed,workpiece feed speed and grinding depth)on the grinding force were analyzed.Secondly,the influence laws of abrasive size,grinding wheel hardness and porosity of white corundum grinding wheel on the grinding force were analyzed.Finally,the influence laws of the three grinding factors on the surface topography of the workpiece were analyzed.The results show that the grinding force increases with the increase of grinding depth.The grinding force increases with the increase of the workpiece feed speed.With the increase of grinding wheel speed,grinding force decreases.With the increase of grinding grains,the grinding force decreases.In order to reduce the grinding force and improve the cutting performance of grinding wheel,white corundum grinding wheel is suitable for selection of J grade hardness and No.4 microstructure.The surface topography of the workpiece can be improved by reducing the grinding depth,the workpiece feed speed and increasing the grinding wheel speed.
