What kind of oil based cutting fluid is good?

This is not easy to say, as long as it is suitable for their own use is good, sometimes others say good, not suitable for their own use, you will not say good, the key is that you try first to see if it is suitable for your workpiece to use, such as we buy Eurasian brand cutting fluid and anti-rust oil products, according to the price and quality to compare, the cost performance is quite high, but whether it is suitable for you then I don't know, or you can also consult their technical personnel. They will make relevant recommendations.

The right product is the best, and the nature of each material is different.

First, the components are different.

Cutting fluid and cutting oil are both cooling lubricants for metal processing, but oil and water are not miscible, although they have the same role and function, but from the materials used in the production have essential differences, cutting oil is mainly composed of base oil and insoluble additives, such as: oily rust inhibitors and lubricants.

The main component of cutting fluid is water, and water-soluble rust inhibitor, lubricant, couplant, bactericide, cleaning agent, etc. are added.

Second, the use of performance is different.

The specific performance is that the cutting oil has good lubrication and anti-rust performance, so the cutting oil is generally used for finishing, and the cutting fluid has good cleaning and cooling performance, and the cutting fluid is mainly used for high-speed machining and rough machining that require good cooling performance.

Third, the maintenance in the process of use is different.

The cutting oil can be supplemented with new oil according to the consumption. Cutting fluids are very susceptible to spoilage during use, resulting in unpleasant odors. Therefore, pay attention to the change of concentration and pH value at any time during use, and add the original solution and water.

Fourth, the difference between cutting fluid and cutting oil in the cost of use.

The cutting fluid should be diluted with water 10-20 times during use. In order to overcome the shortcomings of cutting fluid and cutting oil and give full play to their respective advantages, a new metalworking fluid emulsion is produced by using emulsifiers to organically combine immiscible oil and water.

The lubrication of the cutting oil is good, but the cooling performance is poor. Compared with cutting oil, cutting fluid has relatively poor lubricating performance and better cooling performance. For cutting speeds of less than 30 m minutes, use cutting oil (cutting oil containing extreme pressure anti-wear agent).

When the cutting speed is not higher than 60m minutes in the high-speed cutting stage, due to the large heat generation, the heat transfer effect of the cutting oil is poor, which will make the temperature of the cutting area too high, and the cutting oil will produce smoke and other phenomena, which directly affect the machining accuracy of the workpiece, so water-based cutting fluid is generally used.

The difference between cutting oil and cutting fluid: cutting fluid is often water-soluble and can be processed with water, while cutting oil is a metalworking oil that is insoluble in water and is processed with pure oil. Cutting fluid is required to be diluted with pure water, deionized water and tap water at a certain concentration for cutting, and cutting oil is used directly.

Cutting oil introduction: cutting oil is synthesized by base oil with different proportions of extreme pressure anti-wear agent, lubricant, rust inhibitor, anti-mildew fungicide, cooling wheel section trace agent and other combustion additives, so the product has excellent thorough protection performance for CNC machine tools, cutting tools, workpieces and emulsions. The cutting oil has a super lubricating extreme pressure effect, which effectively protects the tool and prolongs its service life, which can achieve extremely high workpiece precision and surface finish.

Cutting fluid introduction: cutting fluid is a kind of industrial liquid used in metal cutting, grinding process, used to cool and lubricate tools and workpieces, cutting fluid is made of a variety of super functional additives through scientific compounding, and has good cooling performance, lubrication performance, anti-rust performance, degreasing and cleaning function, anti-corrosion function, easy dilution characteristics. It overcomes the problems of traditional soap-based emulsion that it is easy to smell in summer, difficult to dilute in winter, and has poor anti-rust effect, and has no adverse effect on lathe paint, and is suitable for cutting and grinding of ferrous metals, which is the most advanced grinding product at present.

The cutting fluid is better than the saponified oil, it has the characteristics of good cooling, cleaning, rust prevention, etc., and has the characteristics of non-toxic, tasteless, no erosion of the human body, no corrosion of equipment, and no pollution to the environment. Cutting fluid is an important supporting material for metal cutting. The history of human use of cutting fluids dates back to ancient times.

When polishing stone, bronze and iron tools, people knew that watering could improve efficiency and quality. In ancient Roman times, olive oil was used to turn the castings of piston pumps, and in the 16th century, tallow and water solvents were used to polish metal armor. Since 1775, John Wilkinson of England (J Wilkinson) successfully developed a boring machine for machining the cylinder of the Watt steam engine, and the application of water and oil in metal cutting has appeared.

By 1860, after a long period of development, various machine tools such as turning, milling, planing, grinding, gear machining and threading appeared one after another, which also marked the beginning of the large-scale application of cutting fluids.

The components are different: the main hail of the panicle cutting oil should be composed of base oil and water-insoluble additives, and the composition is simple; The main component of cutting fluid is water, and water-soluble rust inhibitors, lubricants, etc. are added, and the components are more complex.

Different performance: cutting oil lubrication and anti-rust performance, used for finishing; The cutting fluid cleaning has good cooling performance, and is mainly used for high-speed machining with good cooling performance.

The cost is different: the use of cutting fluid is 10-20 times more water-thin, while the cutting oil is directly used, so the cost of cutting fluid is relatively low.

Hello dear, additives can be used to improve lubrication in water-based cutting fluids, common additives include: lubricants: hydrogenated fatty acids, sulfonated maleic anhydride and other lubricants are added to water-based cutting fluids, which can reduce the friction coefficient of the shelter and improve the lubrication effect.

Surfactants: such as sodium dodecylbenzene sulfonate, polyoxyethylene stearyl ether, etc., can increase the lubrication and foam stability of water-based cutting fluids. Antimicrobials:

Antimicrobial agents such as isothiazoliline and epichlorohydrin prevent contamination of water-based cutting fluids. Rust inhibitors: such as polyols, fatty acid salts, etc., prevent the oxidation of water-based cutting fluids and rust.

It should be noted that the amount of addition needs to be controlled when adding these materials, so as not to affect the use of water-based cutting fluids. At the same time, different cutting fluid formulations and processes also have an impact on the type and amount of additives, so the specific situation needs to be adjusted according to the actual needs.

Summary. Hello dear.

The lubricity of cutting fluid is relative, and the requirements for lubricity are different for different materials.

For general cast iron carbon steel, general oily agents can be satisfied.

For stainless steel, S, P, Cl extreme pressure agents are mainly added.

Chlorinated paraffins below 400°C perform well.

Above 400°C and 800°C, some extreme pressure agents based on S are required.

For most aluminum alloys, the cutting fluid needs to increase the oil volume, the larger the oil particles, the better the boundary lubrication effect.

For titanium alloy extreme pressure agent, chlorine-containing extreme pressure agent should be used sparingly, which is easy to cause high-temperature stress corrosion.

For cemented carbide, grinding is mostly used, and if CBN grinding wheels are used more, lubricants cannot be added.

What materials are better to use in water-based cutting fluids to improve lubricity?

Hello, the lubricity of the cutting liquid is the right size of the potato ball, and the lubricity requirements for different materials are different. For general cast iron carbon steel, general oily agents can be satisfied. For stainless steel, mainly add S, P, Cl extreme pressure agent, chlorinated paraffin below 400 °C performs well, 400 °C above 800 °C, some need S-based extreme pressure agent.

For most aluminum alloys, the cutting fluid needs to increase the oil volume, the larger the oil particles, the better the boundary lubrication effect. For titanium alloy extreme pressure agent, the chlorine-containing extreme pressure agent should be used less, which is easy to cause high temperature or source force corrosion. For cemented carbide, grinding is mostly used, and if CBN grinding wheels are used more, lubricants cannot be added.

Hello! In water-based cutting fluids, there are many materials commonly used to improve lubricity, such as polyethylene glycol, polyether, phosphate ester, etc. These materials can reduce the coefficient of friction, reduce the heat and wear between the workpiece and the tool, and improve the lubrication performance of the cutting fluid.

Polyethylene glycol is a commonly used thickener and lubricant to increase the viscosity and lubricating properties of water-based cutting fluids. Polyether compounds have excellent lubrication properties and anti-corrosion properties, which can improve the stability and service life of vertical water-based cutting fluids. Phosphate esters have good extreme pressure and anti-wear properties, which can protect workpieces and tools in heavy loads and high temperature environments.

In addition, there are some other ways to improve lubricity, such as adding nanomaterials, optimizing the cutting fluid formulation, controlling the pH value of the cutting fluid, etc. These methods can improve the lubrication performance of water-based cutting fluids, improve cutting efficiency and machining quality. In short, when choosing materials to improve lubricity, it is necessary to consider many factors such as workpiece materials, processing conditions, lubrication properties, etc., and choose the right materials to achieve the best cutting effect.
