H—1高精度磨削液(简称H—1精磨液)是为了满足进口高精度万能外圆磨床及国内高精度磨床的需要而试制的,并于1981年12月由机械工业部机械科学研究院组织进行了技术鉴定。我厂自1981年7月进行生产验证试验及应用,通过将近二年的实践和使用,取得了较满意的效果。H—1精磨液是一种完全不含矿物油,动、植物油,不含亚硝酸钠、硫、磷、氯、酚等 H-1 high-precision grinding fluid (referred to as H-1 refined fluid) is to meet the needs of imports of high-precision universal cylindrical grinder and domestic high-precision grinding and trial, and in December 1981 by the Machinery Industry Mechanical Science Institute of Technology conducted a technical appraisal. I plant from July 1981 for production verification test and application, through nearly two years of practice and use, and achieved more satisfactory results. H-1 refining fluid is a completely non-mineral oil, animal and vegetable oils, non-sodium nitrite, sulfur, phosphorus, chlorine, phenol, etc.
