摘要: 为研究金刚石砂轮修整的工艺,采用绿碳化硅砂轮对金刚石砂轮进行磨削整形法修整。通过改变修整量、修整速比、切削进给量、工作台速度得出修整参数对砂轮磨削性能的影响规律。研究结果表明,工件表面粗糙度随着修整量增加而增大,修整量增加到一定次数时粗糙度变化不大;修整速比增大时,工件表面粗糙度值增大;切削进给量增大时,工件磨削表面粗糙度增大;工作台速度增大时,工件表面粗糙度增大。所得结论为绿碳化硅砂轮修整金刚石砂轮的工艺参数选取提供了切实有效的参考价值。Abstract: To study the dressing process of diamond grinding wheel, the diamond grinding wheel is dressed by green silicon carbide grinding wheel with grinding dressing method. By changing the dressing quantity, dressing speed ratio, cutting feeding, speed of workbench, the influence law of dressing parameters on grinding wheel grinding effect is concluded. The research results show that the workpiece surface roughness increases with the amount of trimming, and the roughness changes little when the amount of trimming increases to a certain number of times; the workpiece surface roughness increases with the increase of dressing speed ratio; when the cutting feeding increases, the workpiece surface roughness increases; and when the workbench velocity increases, the workpiece surface roughness increases. It provides a practical and effective reference value for selecting the technological parameters of dressing the diamond grinding wheel with green silicon carbide grinding wheel.
