修整作为磨削过程的一个组成部分，影响着磨削表面的质量和磨削工具的负荷。研究了微针和极细磨粒砂轮磨削时，不同的修整重叠比（严重偏高）和不同的修整速比（上下修整方式）对载屑量和表面质量的影响。结果表明，磨削表面质量和切屑负荷显着影响的磨削工具的形貌是由修整过程中产生的。非常高的修整重叠率在磨削工具上产生精细的形貌，这导致较低的切屑负载和更精细的表面光洁度。此外，在磨粒上观察到了切屑窝和焊接堵塞。减小修整重叠率，采用向下修整方式时，磨针焊接堵塞较多。镜面质量（Ra=0.035），实现与利用重叠比高达60的砂轮与磨料尺寸#500。
Dressing as an integrated part of the grinding process influences the quality of ground surface and the loading of the grinding tool. This paper addresses the effect of dressing parameters, including the different dressing overlapping ratios (severely high values) and dressing speed ratios (up and down dressing modes) on the chip loading and surface finish in the grinding with micro-pins and grinding wheels with very fine grits. The results revealed that both the ground surface quality and chip loading are significantly influenced by the grinding tool topography which is generated by the dressing process. The very high dressing overlapping ratios generated a fine topography on the grinding tool, which resulted in lower chip loading and finer surface finish. Moreover, both chip nests and welded clogging on the grinding grains were observed. More welded clogging of the grinding pin was detected when the dressing overlapping ratio decreased and down dressing mode was applied. Mirror surface quality (Ra=0.035) was achieved with utilizing overlapping ratios up to 60 for a grinding wheel with grits size #500.
