Experimental investigation on high speed deep grinding characteristics of the nano-cemented carbides
摘要
Abstract
An investigation was undertaken to explore the grinding characteristics in high speed deep grinding of cemented carbide with various grain sizes by using resin-bonded diamond wheels. The experimental investigation focuses on the grinding force,sur-face roughness and the ground surface quality,which influenced by various wheel speeds,feed rates and depths of cut. Experimen-tal results have shown that the increasing of wheel speed,and the decreasing of feed rates and cut depths of cut will lead to the decreasing of maximum chip thickness, grinding force, and improvement of surface quality. A better surface finish, decreased grinding force and specific grinding energy are obtained on the workpiece with a smaller grain size,and the nano-cemented car-bide’ s removal mechanisms are more likely to be brittle. The application of high deep speed grinding on nano-cemented carbide can not only improve the machining efficiency,but also obtain a better surface finish.关键词
