D杯形砂轮修整碟形金刚石砂轮试验研究

本文采用了D杯形砂轮与碟形砂轮对磨法来修整大直径树脂结合剂碟形金刚石砂轮。在分析研究杯形砂轮修整碟形砂轮的修整原理及修整方式的基础上，用自行研制的专用修整装置，从主轴转速、修整深度、修整工具结合剂类型等方面进行了对比工艺试验研究，总结了杯形砂轮修整碟形砂轮的不同工艺参数与修整效率、修整质量之间的工艺规律。试验结果表明，在本试验条件下主轴转速500r／min，修整深度0．02mm的修整效率较好；细粒度、中等浓度的青铜结合剂杯形金刚石砂轮与粗粒度、高浓度的杯形砂轮修整碟形砂轮相比，后者具有较好的修形效果和修整效率；D杯形砂轮与GC杯形砂轮交替配合使用可以大大提高碟形金刚石砂轮的修形效率和修锐效果。

Study on dressing experiment of dish diamond grinding wheel with cup diamond wheel

The dressing experiments on large diameter dish diamond grinding wheel with cup diamond wheel was carried out and studied.Based on the establishment of a theoretic model of dressing dish diamond wheel with cup wheel,a dresser was developed for the experiments.In order to find out the processing rules between different conditions and dressing efficiency and dressing surface quality,a series of contrast experiments were conducted upon dressing the dish diamond grinding wheel with the dresser in different conditions such as different principal axis speed,dressing depth,type of bond and size of diamond of cup wheel.It is concluded that when the principal axis speed is 500r/min and the dressing depth is 0.02mm,the dressing effect will be the best.Comparing small grain size and middle density of cup wheel with big grain size and high density of cup wheel,the latter has better truing efficiency and dressing surface quality.Meanwhile,if the cup diamond wheel and cup GC wheel were used alternately,the dressing efficiency and surface quality can be improved enormously.
