What cutting fluids are commonly used in machining? What does it do?

For high-speed cutting, emulsions, which are a mixture of water and mineral oil, are often used.

It cools the tool, protects the tool, and rinses the chips at the same time.

For low-speed cutting, such as boring, mineral oil is often used as the cutting fluid.

Of course, there are many, many grades of these cutting fluids, and it is inconvenient to list them here.

It mainly plays the role of lubrication and cooling.

When wire cutting, it is soaked in kerosene.

Water-based. Cutting fluids.

It can be divided into emulsion, semi-synthetic cutting fluid and fully synthetic cutting fluid.

The classification of emulsions, semi-synthetic and fully synthetic usually depends on the type of base oil in the product.

Mineral oil. Water-soluble cutting fluid as base oil; Semi-synthetic cutting fluids are water-soluble cutting fluids that contain both mineral and synthetic base oils, while fully synthetic cutting fluids are water-soluble cutting fluids that use only chemically synthesized base oils (i.e., no mineral oils).

Each type of cutting fluid will contain a variety of additives other than base oils: rust inhibitors, non-ferrous corrosion passivators, defoamers, etc. Some microemulsions are classified as being between emulsions and semi-synthetic cutting fluids.

The dilution of the emulsion is milky white in appearance, the dilution of the semi-synthetic solution is usually translucent, there are also some products that are milky white, and the dilution of the all-synthetic solution is usually completely transparent like water or slightly colored in a certain color.

Cutting fluid (coolant) is a kind of industrial liquid used in the process of metal cutting and grinding to cool and lubricate tools and processed parts.

The composition of machining cutting fluid is mainly composed of the following parts:1Lubricating oil:

It is the most important ingredient whose function is to provide lubrication, cool the cutting parts in front of the god, and prevent the heat from spreading too quickly. 2.Surfactants:

This is a substance that can effectively reduce the coefficient of friction of machining cutting fluid, which can effectively improve the efficiency of machining and cutting. 3.Preservatives:

It is a substance used to prevent the deterioration of oil added to the machining fluid. 4.Antirust agent:

This is a special chemical substance that can effectively prevent the oxidation of the oil added to the machining fluid. 5.Conditioners:

This is a substance used to regulate the pH and temperature of the machining fluid. 6.Cleaning agent:

This is a substance that is used to remove residues left on the cutting parts. 7.Additives:

This is a substance that can effectively improve the performance of machining cutting fluids, and is generally used to improve lubrication properties and reduce the coefficient of friction.

What is the composition of cutting fluid?

1. Oil-soluble additives and extreme pressure additives; The function is to play the role of wetting and lubrication when processing metal, reduce the tension of the contact interface between metal and cutting fluid, and prevent damage to metal workpieces. As we all know, any cutting fluid has a lubricating effect, and the cutting fluid is a lubricant to relieve this friction between the tool and the surface of the workpiece. This reduces scrap of tools and metal workpieces.

2. Anti-rust additives are first of all to prevent machine tools, tools, and metal workpieces from being corroded. If there is no anti-rust function, it will lead to corrosion of the workpiece. This is a very polar coarse imitation balance.

3. Anti-mildew additives prevent bacteria from multiplying and play a bactericidal role.

4. Anti-foam additives to prevent excessive foam during metal workpiece processing, which will affect the processing effect.

5.The emulsifier can make the oil-soluble cutting fluid be arranged and adsorbed on the oil-water two-phase interface, reducing the oil-water interface tension.

Hello, dear. Components of this orange machining cutting fluid: ethylene glycol, sodium tetraborate, sodium metasilicate, sodium phosphate.

Ethylene glycol: Ethylene glycol, also known as "glycol", "1,2-yawuyun ethyl glycol", referred to as EG. The chemical formula is (hoch2) and is the simplest diol.

Sodium tetraborate: Sodium tetraborate, or borax, with the molecular formula Na2B4O7·10H2O, is a very important boron-containing mineral and boron compound. Sodium metasilicate:

Sodium metasilicate is a low-molecular weight crystal prepared by the hydrothermal reaction of ordinary bubbled alkali and caustic soda, and the commodities include anhydrous, pentahydrate and Senshu nine hydrate.
