Novel cutting fluid capable of effectively reducing wear of titanium-alloy high-speed cutting tool

Abstract

The invention provides a novel cutting fluid capable of effectively reducing wear of a titanium-alloy high-speed cutting tool. The fluid is prepared from the following raw materials by mass: 2.5% of sodium carbonate, 15% of triethanolamine, 2% of methyl silicone oil, 5% of polyethylene glycol, 1% to 5% of cetyltrimethylammonium bromide, with the balance being deionized water. According to the invention, due to the addition of cetyltrimethylammonium bromide, the novel cutting fluid exerts good wear reducing effect on the cutting tool; harmful substances like nitrite are not contained, so the fluid is healthy and environmentally friendly; and a preparation method for the fluid is simple and has low cost.

Description

technical field [0001] The invention belongs to the technical field of metal cutting, and in particular relates to a novel oil-free water-based cutting fluid which uses cetyl dimethyl ammonium bromide as a dissolution medium. Background technique [0002] Titanium alloys are widely used in the processing and manufacturing of aerospace parts because of their excellent comprehensive properties such as high strength, good corrosion resistance, and high heat resistance. However, titanium alloy is a typical difficult-to-machine material, and the tool wear is serious in its high-speed cutting. At present, the wear problem of titanium alloy high-speed cutting tools has become one of the outstanding process problems faced by the aviation manufacturing industry. In metal cutting, the use of suitable cutting fluid is an effective measure to reduce tool wear. In the middle of the 20th century, the commonly used cutting fluid was low-viscosity machine oil or emulsified oil-based cutti...

Problems solved by technology

In the middle of the 20th century, the commonly used cutting fluid was low-viscosity engine oil or emulsified oil-based cutting fluid, which could achieve cooling and lubrication effects to a certain extent, but the cost was high and the environment was seriously polluted.

In the late 20th century, water-based cutting fluids emerged. These cutting fluids are mainly composed of water and contain lubricants and anti-rust agents, which have certain cooling and lubricating properties. High-level defects, some products also have disadvantages such as polluting the environment, sedimentation of impurities, large oily smoke during cutting, and skin damage

At present, cutting fluids in the field of cutting processing are difficult to achieve satisfactory results, especially for high-speed cutting of titanium alloys, a typical difficult-to-machine material. Existing cutting fluids cannot effectively solve the problem of rapid tool wear. A breakthrough has been made in the composition of cutting fluid and the mechanism of anti-friction and anti-wear
