    • PROBLEM TO BE SOLVED: To provide a regeneration method of a used cutting oil composition for a fixed abrasive grain wire saw, the method being capable of easily separating a cutting powder in a high separation efficiency from a waste oil containing a used cutting oil composition and the cutting powder generated by cutting a silicon ingot to improve recyclability of the cutting oil composition.SOLUTION: A cutting oil composition before use contains a specific polyether compound (component A) of 25 mass% or more and 75 mass% or less, a specific surfactant (component B) of 1 mass% or more and 9 mass% or less, and water (component C). In a regeneration method of a used cutting oil composition for a fixed abrasive grain wire saw, a powder removing step for removing at least a cutting powder from a waste oil includes a step for separating the cutting powder in the waste oil in the pH range of 6.0 or more and 9.0 or less from other components in the waste oil.
    • 要解决的问题:为了提供一种用于固定磨粒锯线锯的用过的切削油组合物的再生方法,该方法能够容易地将分离效率高的切割粉末与含有使用的切削油组合物的废油分离, 通过切割硅锭产生的切割粉末,以提高切削油组合物的可回收性。解决方案:使用前的切削油组合物含有25质量%以上且75质量%以下的特定的聚醚化合物(成分A),特定的 表面活性剂(组分B)为1质量%以上且9质量%以下,水(成分C)。 在用于固定磨粒线锯的所用切割油组合物的再生方法中,从废油中去除至少一种切割粉末的粉末去除步骤包括:在废油的pH范围内分离废油中的切割粉末的步骤 6.0以上,9.0以下,废油中的其他成分。
