与传统金属结合剂金刚石砂轮相比，多孔金属结合剂金刚石砂轮在难加工材料磨削加工时具有磨料易出刃、修整修锐方便和磨削效率高等优点。以人造金刚石、Fe∶Ni-Cr合金金属结合剂及造孔剂为原料，通过真空高温烧结法，制备多孔金属结合剂金刚石砂轮节块。通过排液法测定节块试样的孔隙率，研究原料及其不同配比对节块孔隙率的影响规律，为多孔金属结合剂金刚石砂轮制作提供试验数据。
與傳統金屬結閤劑金剛石砂輪相比，多孔金屬結閤劑金剛石砂輪在難加工材料磨削加工時具有磨料易齣刃、脩整脩銳方便和磨削效率高等優點。以人造金剛石、Fe∶Ni-Cr閤金金屬結閤劑及造孔劑為原料，通過真空高溫燒結法，製備多孔金屬結閤劑金剛石砂輪節塊。通過排液法測定節塊試樣的孔隙率，研究原料及其不同配比對節塊孔隙率的影響規律，為多孔金屬結閤劑金剛石砂輪製作提供試驗數據。
