在线电解修整（ＥＬＩＤ） 磨削是镜面磨削加工的新技术． 在分析ＥＬＩＤ 镜面磨削机理的基础上，对ＥＬＩＤ磨削过程中影响砂轮耐用度的主要因素，包括电解修整参数、磨削液成分、磨削工艺参数和砂轮结合剂等进行了实验研究和理论分析，说明由于在线电解修整过程中的非线性电解作用，这些因素对砂轮磨损速度的影响可以通过残留维持电流反映出来，最后根据在线电解修整过程的特点，给出了用残留维持电流估算砂轮耐用度的计算公式． Online electrolytic dressing (ELID) grinding is a new technology of mirror grinding. Based on the analysis of the mechanism of ELID mirror grinding, the main factors affecting the durability of the grinding wheel in ELID grinding process, including the parameters of electrolytic dressing, the composition of grinding fluid, grinding process parameters and grinding wheel binder, were studied and the theory The results show that the influence of these factors on the wear rate of the grinding wheel can be reflected by the residual holding current due to the nonlinear electrolysis in the online electrolytic dressing process. Finally, according to the characteristics of the online electrolytic dressing process, Degree of the formula.
