摘　　要：在基于大量实验的基础上,对磨削钢结硬质合金时磨削力的变化规律进行了详细分析,并将磨削力、磨削表面粗糙度与普通磨削进行了比较。结果表明,采用铸铁结合剂金刚石砂轮进行ELID磨削时磨削力几乎不随时问的变化而变化,而采用普通磨削方式进行磨削时的磨削力随时间的变化不断增大,在线电解修整使砂轮在磨削过程中始终保持良好的磨削性能,有利于节省砂轮修整时间,提高加工效率。在ELID磨削中,采用微细砂轮进行磨削可以获得很低的表面粗糙度,实现了对钢结硬质合金的超精密镜面磨削。It based on the massive experiment, has carried on strength of grinding steel bonded carbide, and the grinding strength, the detailed analysis to the compared with the ordinary grinding by grinding strength and surface-roughncss. The result indicated that the grinding strength when grinding carried on ELID does not change along with the time change. While it increases unceasingly along with the time change in ordinary grinding. The ELID causes the grinding wheel maintains the good grinding performance throughout in the grinding process, raises the processing efficiency. In the process of ELID roughness of the surface can be very low by using very fine grinding wheel. Mirror surface grinding ,the of steel bonded carbide could be realized by ELID.
