钢结硬质合金的精密镜面磨削

Precision Mirror Surface Grinding of Grinding Alloy

引入一种新型的在线电解连续修整砂轮磨削方法──ＥＬＩＤ磨削，对钢结硬质合金进行精密镜面磨削，得到了Ｒｚ＝０．０９１μｍ的良好镜面表面，一次磨削成形，效率高，可取代目前的多级研磨工艺。

A new kind of application of continuous repair and maintain grinding with an electrolytic in-process dressing wheel(ELID) for precision mirror surface grinding of carbide al- loy is introdued, and good surface Rz-0.091um is obtained. It is efficient and can be finished first time, and can take place of present multistage grinding.
