【摘要】 介绍一种新型磨料——氧化铝纳米陶瓷,其硬度接近金刚石,打磨时,能承受大压力施压,打磨速度快、磨具使用寿命长。微细转印砂带的问世,改变了磨粒粘附在衬带上的方式,并将磨削助剂添加在砂带上,使砂带的打磨效率提高,使用寿命延长。更多还原

【Abstract】 A new abrasion material-Al₂O₃ ceramics near to diamond in hardness was introduced.The abrasion material can be subjected to high pressure during abrasion so that the faster the abrasive velocity is,the longer the service life of the abrasive tool is.The advent of microreplication abrasive belt has changed the way of abrasive particle adhering on the substrate belt and added abrasive agent on the abrasive belt,which can improve the abrasive efficiency and extend the service life.更多还原
