摘要
随着国防尖端技术的迅速发展,许多具有独特性能的新材料得到了日益广泛的应用,如光学玻璃、硬质合金。但采用传统磨削工艺加工这些材料很难得到良好的表面质量。在线电解砂轮修整(ELID)磨削技术是一项新的、高效的磨削方法,它有效实现了许多难加工材料的超精密加工和高效加工。针对光学玻璃的特性,将ELID磨削方法应用于光学玻璃的精密加工,通过试验研究ELID磨削中电解参数对加工表面的影响规律,找到了在一定条件下优化的电解参数。试验结果表明,在ELID中,工艺参数对磨削质量及磨削效率有着显著影响,优化工艺参数对ELID镜面磨削有着重要的意义。
With the development of the most advanced national defense technology, materials with special performance, such as optical glass, hard alloy, are applied increasingly in recent year. But the well surface of these materials ground with general grinding is achieved difficultly. Electrolytic in-process dressing （ ELID ） grinding is new and efficient method that uses a metal-bonded diamond grinding wheel in order to achieve a mirror surface finish especially on and brittle materials. According to feature of optical glass, ELID grinding technique has been used to the ultra-precision of optical glass, the law of the electrolytic parameter in ELID grinding influencing on the surface quality is studied through the experiment and optimized parameter is found. The experiment results show that in ELID the technology parameter has remarkable function in grinding quality of and grinding efficiency, optimizing the technology parameter has important meaning to ELID grinding.
