Author develop ELID grinding technology system, on MM7120A surface grinder and fulfilled a lots of ELID ultraprecision mirror grinding for kinds of hard and brittle materials. To use this method, the surface roughness of mechined materials can reach nanometer gade (Ra0.006～0.010 μm), and can replace parts of grind and polish technology.

本文作者开发了在MM7120A平面磨床上的ELID磨削工艺系统，实现了对多种硬脆材料的ELID精密镜面磨削试验，工件表面粗糙度可达nm级（Ra0.006-0.010μm），可取代部分硬脆材料的研磨、抛光工艺。

They stretch out, the matte green of their leaves conveying what it would be like to touch them, to run your finger down the blade and feel the rough resistance of these durable plants' skin: the gama grass, rough hair grass and broom beard grass.

瓜地马拉草、翦股颖和小蓝茎草的细长叶片四处伸展，黯淡的表面想也知道摸起来大概是怎样的质感，用指头顺著叶脉滑下，就可感受到这些强韧植物的粗糙叶面。

This research presented a new guide mechanism and belt driving theory of the abrasive band polishing for inner aperture, satisfied the driving requirement of abrasive belt leading smoothly into grinding area, realized the band grinding and band polishing of inner aperture, developed a abrasive band polishing headstock for of the ball track of ball bearing and roller bearing individually adopting a way of curvature concave oscillating and vibrating, researched the process regular and fundamental process method and parameter of abrasive band polishing of ball track. The results of experiments and tests showed that the surface roughness of ball track by abrasive band polishing can reach Ra0.02μm, and the original geometric cross section shape precision of ball track can be kept.

本项研究提出了砂带研抛内孔的新型导引机构和传带原理，满足了砂带平稳导入内孔磨削区的传动要求，实现了内孔的砂带磨削和研抛；研制了采用弧面摆动和振动方式分别用于球轴承滚道和滚柱轴承滚道研抛的砂带研抛头架；研究了轴承滚道砂带研抛的工艺规律和基本工艺方法、工艺参数；实验测试结果，轴承滚道砂带研抛的表面粗糙度达Ra0.02μm，研抛过程保持了滚道的原始几何截面形状精度。
