Water-based cutting fluid used for processing neodymium-iron-boron material slices and application method thereof

Abstract

The invention discloses a water-based cutting fluid used for processing neodymium-iron-boron material slices and an application method thereof. The cutting fluid comprises the following components in parts by weight: organic amine, organic acid, water-soluble phosphate, polyether, antirust corrosion inhibitor, dispersing agent and surfactant, antiseptic bactericide, anti-hard-water agent, defoaming agent, auxiliary agent and water, wherein environmentally-friendly lubricating agent, extreme-pressure agent and antirust agent are reasonably matched in the cutting fluid disclosed by the invention, thus the lubricating property, extreme pressure property and antirust property of the cutting fluid are guaranteed; organic base, organic acid and special auxiliary agent are reasonably matched, thus the corrosion dissolution phenomenon of the cutting fluid to adhesive is greatly weakened; the dispersing agent and the surfactant are used for reducing surface tension of solution, thus permeability and settlement performance of the cutting fluid are enhanced; pH value of a final product is 7.5-8.5; and solubility of the cutting fluid to adhesive used for binding neodymium-iron-boron material in a processing cycle is extremely low, and the condition that product processing accuracy error is large or a tool is damaged as the adhesive is dissolved by the cutting fluid can not be caused.

Description

technical field [0001] The invention relates to a lubricating cooling fluid for mechanical processing and a using method thereof, in particular to a water-based cutting fluid used for slicing processing of neodymium-iron-boron materials and a using method thereof. Background technique [0002] NdFeB materials contain rare earth elements, have active chemical properties, and the powder metallurgy body has gaps, and different metals are easy to form galvanic reactions, making them easy to oxidize and corrode, and the material itself has high hardness and brittleness, which is difficult to process Material. At present, RuFeB materials need to be bonded to each other by wax (shellac) or 502 glue before being sliced. Therefore, in its slicing process (mainly inner circle slicing) process, it is necessary to use a cutting fluid that has good lubrication, antirust, cleaning, cooling and sedimentation effects, and has a very small solubility to the adhesive within a certain period ...

AI Technical Summary

Problems solved by technology

[0007] Therefore, there is a need for a cutting fluid suitable for slicing of NdFeB materials, which has the advantages of good lubricity, good rust resistance, good cleaning performance and good sedimentation performance, and at the same time will not dissolve and bond NdFeB material within a certain period of time. The glue used for iron-boron materials can avoid serious accidents such as increased product processing accuracy errors or tool damage caused by loosening or falling off of the bonded workpieces.
