Problems solved by technology

Due to the high cutting temperature of stainless steel during cutting, at high temperature, this small adsorption force is easily destroyed, making its oiliness lose its effect, and metal-to-metal contact friction occurs, causing severe wear
[0004] However, the existing cutting fluids, due to the high cutting force and high cutting heat generated when cutting stainless steel, cannot fully cool the machining process, and have low lubricity, anti-rust performance and penetration ability.

Abstract

The invention belongs to the technical field of metal processing, and particularly relates to a high-lubrication stable cutting fluid and a preparation method thereof. The high-lubrication stable cutting fluid is prepared from, by weight, 40 to 46 parts of diethylene glycol, 5 to 8 parts of triethanolamine, 2 to 5 parts of diethanolamine, 5 to 10 parts of an emulsifier, 14 to 18 parts of a corrosion inhibitor, 0.02 to 0.5 part of an organic silicon defoamer and 20 to 25 parts of water. A special emulsifier is adopted to improve the permeability and the lubricating property, and the high-lubrication stable cutting fluid serving as an oil-free cutting fluid product can replace a semi-synthetic cutting fluid with low oil content under the same condition. Besides, compounding of a special antirust agent makes the surface of a lubricating film keep smooth for a long time, so that dry friction caused by direct contact between a cutter surface and a workpiece is avoided, the contact length between a cutter and chips is shortened, the shearing angle is increased, and the cutting difficulty is reduced.

Description

technical field [0001] The invention belongs to the technical field of metal processing, and more specifically, the invention relates to a high-lubricating and stable cutting fluid and a preparation method thereof. Background technique [0002] The cutting process of general materials is a mixture of fluid lubrication and boundary lubrication. Fluid lubrication means that the surfaces of two moving objects are completely separated by a continuous lubricant film, preventing direct friction between objects. For difficult-to-machine materials such as stainless steel, the cutting force is large during cutting, and the vertical stress between the tool face and chips can generally reach tens of thousands of Newtons. Under such a high pressure, the lubricant film is completely crushed, and direct friction occurs between the tool and the cutting tool, and fluid lubrication is not obtained, so it is similar to a boundary lubrication state. [0003] Therefore, for difficult-to-machi...
