对于玻璃、陶瓷等硬脆材料,传统的镜面磨削方法一般要通过逐渐减小砂轮粒度、去除前道工序加工变质层的同时,最终获得镜面,不但加工时间长,而且加工成本也很高。为此,日本宇都宫大学的市田良夫等,开发了一种一次走刀镜面磨削法,即通过一次走刀磨削,去除粗磨时产生的加工变质层,并获得所需镜面,使工件表面粗糙度由R_(max)=110μm,变为R_(max)≤50nm,力争R_(max)≤30nm。
For hard and brittle materials such as glass and ceramic, the traditional mirror grinding method generally obtains the mirror surface by gradually reducing the size of the grinding wheel, removing the deteriorated layer in the previous process, and not only the processing time is long, but also the processing cost is also high. To this end, Shippo Uchida, Utsunomiya University, Japan, developed a one-time knife mirror grinding method, that is, through a walk grinding to remove coarse processing of the metamorphic layer produced, and to obtain the required mirror so that The surface roughness of workpiece is changed from R max (max) = 110μm to R max ≤50nm, striving to be R max ≤30nm.
