摘要
针对K9光学玻璃研磨抛光过程中存在的问题,将磁性研磨加工方法应用在光学玻璃的研磨抛光上。试验表明,K9玻璃的表面粗糙度值Ra由原来的90nm左右下降到40nm左右。为进一步研究磁性研磨试验的4个因素,设计了正交试验,最终得出各个因素对于工件表面粗糙度影响的主次顺序,并确定其最优组合为:磁极转速2300r/min,加工间隙1.5mm,磁感应强度0.4T,进给速度200mm/min。
To study the existing problems of polishing K9 optical glass,magnetic abrasive finishing was put forward in polishing optical glass.Results showed that surface roughness Raof K9 glass decreased from 90 nm to 40 nm.Based on the feasibility study,the magnetic abrasive finishing experiments were performed by orthogonal experiment with 4parameters.Then various factors of magnetic abrasive finishing were listed in sequence.The optimum combination was that：pole speed of 2300r/min,working clearance of 1.5mm,magnetic flux density of 0.4Tand feed rate of 200mm/min.
