GCr15钢的ELID磨削性能实验研究

为了探讨GCr15钢的ELID（Electrolytic In-process Dressing）磨削性能，在基于大量实验的基础上，对GCr15钢采用ELID磨削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CBN砂轮进行ELID磨削时磨削力几乎不随时间的变化而变化，而采用白刚玉砂轮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CBN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，实现对GCr15钢的超精密镜面磨削。

Research on ELID grinding performance of GCr15 steel

ELID grinding performance of GCr15 was discussed.Based on the experimental results,the variation of grinding force in the process of ELID(electrolytic in-process dressing) grinding was researched.Grinding force and surface roughness of ELID grinding compared to conventional grinding were also analyzed.The results showed that the grinding force variation in the process of ELID grinding using cast-iron bond CBN wheel was small and constant,while in conventional grinding using white fused alumina wheel the grinding force was larger and increased with the time progresses.Electrolytic in-process dressing keeps the wheel sharpening in the grinding process,so the machining efficiency can be improved by saving dressing time.In the process of ELID,the roughness of the surface can be very low by using very fine grinding wheel.Mirror surface grinding of GCr15 steel could be(realized) by ELID.
