Abstract

The invention discloses a cutting fluid for after-cutting processing of neodymium iron boron. The cutting fluid comprises the following components, by weight: 5-7% of ethylenediamine, 14-16% of isopropanol amine, 8-10% of oleic acid, 1-3% of sebacic acid, 3-5% of water-soluble phosphate, 4-6% of polyether, 12-14% of methyl benzotriazole, 0.5-0.7% of TX-10, 6-8% of polyvinyl alcohol, 0.1-0.3% of 5-chlorine-2-methyl-4-isothiazolin-3-one, 0.5-0.7% of emulsified oil, 3-5% of isopropyl alcohol and the balance of water.
