主 题：Magnetic field-assisted Mass finishing Optical glass Ultra-precision machining polishing
摘 要：The demand for optical glass has been rapidly increasing in various industries,where an ultra-smooth surface and form accuracy are critical for the functional elements of the *** meet the high surface-quality requirements,a polishing process is usually adopted to finish the optical glass surface to ensure an ultra-smooth surface and eliminate sub-surface ***,current ultra-precision polishing processes normally polish workpieces individually,leading to a low production efficiency and high polishing *** mass-finishing methods cannot be used for optical ***,magnetic-field-assisted batch polishing(MABP)was proposed in this study to overcome this research gap and provide an efficient and cost-effective method for industrial use.A series of polishing experiments were conducted on typical optical components under different polishing parameters to evaluate the polishing performance of MABP on optical *** results demonstrated that MABP is an efficient method to simultaneously polish multiple lenses while achieving a surface roughness,indicated by the arithmetic mean height(Sa),of 0.7 nm and maintained a sub-micrometer surface form for all the *** addition,no apparent sub-surface damage was observed,indicating the significant potential for the high-quality rapid polishing of optical *** proposed method is highly competitive compared to the current optical polishing methods,which has the potential to revolutionize the polishing process for small optics.
