采用硬质合金圆盘刀进行电磁钢板的圆盘剪分切试验，利用轮廓仪和光学显微镜等检测分析了不同分切长度时圆盘刀的磨损情况及电磁钢板分切断面形貌，研究了圆盘刀的磨损规律及其对分切质量的影响。结果表明，圆盘剪分切中硬质合金圆盘刀的磨损，主要表现为刃口半径和侧边磨损带宽度的增大，而圆柱面的表面粗糙度变化不大。随着分切长度的增加，圆盘刀的磨损加剧，侧面磨损带宽度逐渐增大，刃口半径也随之增加。圆盘刀的磨损直接影响了分切断面质量，当电磁钢板分切长度达到8000 m左右时，刃口半径超过43μm ，板材分切断面质量恶化。硬质合金圆盘刀使用的最佳分切长度在8000 m以内、刃口半径小于43μm。

The disc slitting machining experiments for the electromagnetic steel sheet were conducted to investigate the wear process of carbide alloy disc cutter and its effect on the slitting quality in the disc slitting process ,and the blade contour shape and wear of disc cutter and the slitting surface morphology of electromagnetic steel sheet were examined by the surface profiler and op‐tical microscopy .The results show that wear of disc cutter mainly presents the increase of the blade radius and side wear zone of the cutter ,and the surface roughness of the cutter cylindrical surface does not almost change .As the slitting length increases , both the blade radius and the side wear zone of the disc cutter increase ,so the cutter's wear becomes serious .The wear of the disc cutter influences directly the slitting quality of the electromagnetic steel .The quality of the slitting surface will deteriorate when the slitting length of the disc cutter is more than 8000m and the blade radius is over 43μm .The optimum parameters of the carbide alloy disc cutter are:the slitting length is less than 8000m and the blade radius is less than 43μm .
