摘要:
采用树脂结合剂金刚石砂轮对纳米晶粒硬质合金进行平面磨削试验，结合单因素和正交实验研究不同磨削要素即磨削深度ap、工件进给速度vw、砂轮线速度vs 对磨削纳米晶粒硬质合金表面粗糙度的影响。结果表明，磨削深度ap 和工件进给速度vw 增加，表面粗糙度增加?砂轮线速度vs 增加，表面粗糙度减小。磨削3 要素对纳米晶粒硬质合金表面粗糙度影响程度的大小依次是工件进给速度、砂轮线速度、磨削深度。因此，为了获得好的表面质量可以采取小进给、小切深、高砂轮线速度的组合方式进行磨削?同时建立了磨削纳米晶粒硬质合金的表面粗糙度数学模型并验证了模型的可靠性。
Abstract:
The surface grinding test of nano-grained cemented carbide was conducted with resin bond diamond grinding wheels, combined with single factor test and orthogonal experiment to study the effects of the grinding elements, namely grinding depth ap, workpiece feed speed vw, grinding wheel linear speed vs, on the surface roughness of nano-grain cemented carbide. Test results show that once the grinding depth ap and workpiece feed speed vw increase, the surface roughness increases; once the grinding wheel linear speed vs increases, the surface roughness decreases. The influence of the three elements on the surface roughness of nano-grained cemented carbide can be determined from large to small in the order of the workpiece feed speed, the linear speed of the grinding wheel, and the grinding depth. Therefore, in order to obtain a good surface quality, a combination of small feed, small depth of cut, and high grinding wheel linear speed can be used for grinding; at the same time, a mathematical model of surface roughness for grinding nano-grained cemented carbide was established and its reliability was verified.
