Problems solved by technology

NdFeB products are easy to oxidize and corrode due to their active chemical properties, gaps in powder metallurgy bodies, and galvanic battery reactions between different metals due to the rare earth elements contained in the product itself, and the general water-based cutting fluid is difficult to fully meet its processing requirements. Require
Judging from the existing patents, documents and technologies, the existing cutting fluids can be mainly applied to the cutting and grinding of metals such as iron, aluminum, copper, etc. There are not many reports on water-based cutting fluid products for post-processing of sintered NdFeB. Even if there is a small amount of reports, there are such and other defects, which cannot meet the needs of use

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...
