摘　　要：在数控车床上,应用新型磨具——SN弹性砂轮,将车抛磨工序集于一身,扩展了数控车床的加工范围,尤其适合重要零件的加工和修复。在数控改造中,采用特殊的结构,将一般数控机床单一的单位控制精度改造为多单位控制精度,并针对实际加工中需要的不同抛磨次数,采取特殊的程序结构予以处理,可以实现对SN弹性砂轮弹压量和砂轮磨损的瞬时自动补偿。Turning, grinding and polishing are combined to extend the machining range by using the new grinding tool——SN elastic grinding wheel in NC machine tool, especially suitable for machining and repairing key parts. In NC reconstruction, special structure is employed for changing the single unit control precision into several unit control precision, meanwhile, special program structure is used to deal with different times of polishing in practical machining. Furthermore, instantaneous automatic compensation for the elastic amount and the wear of SN elastic grinding wheel is realized.
