摘　　要：硫系玻璃是应用较为广泛且较难加工的红外光学元件。单点金刚石车削加工技术不仅具有较高的加工质量,还能有效避免磨料嵌入光学元件导致面形精度降低,适用于小口径、大批量硫系玻璃镜片的超精密加工。本文介绍了硫系玻璃单点金刚石车削加工的原理和条件,综述了硫系玻璃单点金刚石车削加工过程中机床、刀具、加工工艺等对面形精度和表面光洁度的影响。Chalcogenide glass is an infrared optical element which is widely used and difficult to process.Single point diamond turning technology not only has high processing quality,but also can effectively avoid the reduction of surface shape accuracy caused by abrasive embedded in optical elements.It is suitable for ultra-precision machining of small-caliber and large-volume chalcogenide glass lenses.In this paper,the principle and conditions of single point diamond turning of chalcogenide glass are introduced.The influences of machine tools,tools and processing technology on surface shape accuracy and surface finish in single point diamond turning processing of chalcogenide glass is reviewed.
