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.

Description

technical field [0001] The invention relates to the technical field of magnetic material cutting, in particular to a cutting fluid for post-cutting of neodymium iron boron. Background technique [0002] With the improvement of cutting technology, there are more and more types of cutting fluids. According to its type, it can be roughly divided into two categories: oil-based cutting fluid and water-based cutting fluid. [0003] Oil-based cutting fluids mostly use mineral oil, fatty oil, mixed oil and extreme pressure oil as raw materials, and generally have good lubricity, but poor cooling performance. Used in high-speed and heavy-duty cutting processes, the environmental sanitation will be deteriorated due to violent smoke, and there may even be a risk of fire. The splashing and scattering of oil also aggravates the pollution to the environment. At the same time, in order to prevent oxidative deterioration and improve its lubricating extreme pressure performance, it is ofte...
