A cutting fluid for high-efficiency bearing grinding and cutting, its preparation method and use method

Abstract

The invention relates to the technical field of cutting fluids, in particular to a cutting fluid for high-efficiency bearing grinding and cutting, a preparation method and an application method thereof. The cutting fluid comprises 10-20 parts of water-soluble alcoholamine, 3-12 parts of a preservative of a dicarboxylate-based composite, 2-10 parts of an emulsifier, 2-8 parts of synthetic resin, 2-8 parts of a film-forming agent, 1-3 parts of hexanediol, 0.1-1 part of benzotriazole, 1-3 parts of a pH adjuster, 15-25 parts of base oil, and 30-40 parts of deionized water. The preparation steps ofthe invention are as follows: first, heating sebacic acid, dodecane dibasic acid, methyl benzotriazole, neodecanoic acid, isopropanolamine and water to 55-65 DEG C to completely dissolve into a transparent liquid, adding water-soluble alcohol amine, base oil, benzotriazole, deionized water and a pH adjuster to stir to be even and transparent, finally adding the emulsifier, the synthetic resin, the film-forming agent, and hexanediol, and stirring to be transparent. The cutting fluid for high-efficiency bearing grinding and cutting facilitates workshop management and the appearance of rust anddark spots can be avoided.

Description

technical field [0001] The invention relates to the technical field of cutting fluid, in particular to a cutting fluid for high-efficiency bearing grinding and cutting, a preparation method and a use method thereof. Background technique [0002] Traditional bearing grinding fluids are generally divided into two types: one is coarse grinding fluid and the other is fine grinding fluid. This brings inconvenience to the management of the workshop, and may cause the workers in the workshop to often add the wrong cutting fluid, resulting in wrong use. More importantly, the rough grinding fluid often only focuses on the cooling performance, not on other aspects of performance, causing the bearings in the process to rust after rough machining, black spot corrosion, etc.; , Black spot corrosion occurs during storage between processes. The main reason for this kind of problem is that the performance of the cutting fluid against electrochemical corrosion is not good, and no effective...

Problems solved by technology

This will bring inconvenience to the management of the workshop, and may cause the workers in the workshop to add the wrong cutting fluid from time to time, resulting in wrong use

What's more, the rough grinding fluid often only focuses on cooling, not on other aspects of performance, causing the bearings in the process to rust after rough machining, black spot corrosion, etc.; , black spot corrosion occurs during storage between processes

The main reason for such problems is that the performance of the cutting fluid against electrochemical corrosion is not good, and no effective corrosion inhibitor is added.

In addition, in the process of bearing grinding, sulfurized grinding wheels are often used, which will cause the sulfur element inside to directly enter the cutting fluid, causing electrochemical corrosion of metal iron, and the cutting fluid currently on the market is generally only Increasing anti-rust by adding anti-rust agent, or non-environmentally friendly sodium nitrite, will not achieve the effect of solving the problem
