硬质合金平面,外圆、型面的电解磨削在我国应用已有近廿年的历史,长期的使用实践说明,电解磨削硬质合金后表面不产生显微裂纹,光洁度好、生产率高,能大幅度延长金属粘结砂轮的使用寿命。目前,广泛使用以亚硝酸钠为基体的电解液,最典型的配方是国内外普遍使用的ELY—10型电解液,其成份为(重量百分浓度): 亚硝 Carbide plane, cylindrical, profile electrolytic grinding in China has been applied for nearly 20 years of history, long-term use of practice shows that the electrolytic grinding of cemented carbide surface does not produce micro-cracks, good finish, high productivity , Can greatly extend the service life of metal bonding wheel. At present, sodium nitrite is widely used as the base of the electrolyte, the most typical formula is commonly used at home and abroad ELY-10-type electrolyte, its composition (weight percent concentration): nitrite
