Metalworking fluid is a general term for all cutting oils, cutting fluids, cleaning agents, rust inhibitors, grinding fluids, rolling fluids and other liquids used in the metalworking process.

Metalworking fluids (Metalworking fluids) are mainly liquids used for metal processing, which are mainly used for lubrication and cooling, as well as rust prevention and cleaning. General metalworking fluids include cutting fluids, cutting oils, emulsions, stamping oils, quenching agents, high temperature oils, extreme pressure cutting fluids, grinding fluids, anti-rust oils, cleaning agents, blackening agents, deep drawing oils, etc. Metalworking cutting fluid is a soluble lubricant with low foam and high lubricity. It can minimize the maintenance cost even if it is used in an environment with high requirements for machining fluid. It can basically be applied to all kinds of metals and alloys. Type of processing, it is very effective for the general processing of most iron metals, especially when processing mild steel, cast iron, stainless steel and other special steels, it can play an excellent lubrication and cooling effect at the same time.

What are the classifications of metalworking fluids

Metalworking fluids are complicated. In terms of composition, metalworking fluids can be roughly divided into four types: pure oil, soluble oil, chemical fluid (synthetic fluid) and semi-chemical fluid (semi-synthetic fluid). The latter three are usually also called water. Base metal working fluid. Metalworking fluids are usually classified by the content of mineral oil:

Metalworking fluids are usually classified by the content of mineral oil:

⑴ Pure oil metal working fluid, the oil content is 90%-95%.

⑵ Emulsified metal working fluid, mineral oil content exceeds 50%

⑶ Semi-synthetic metal working fluid with mineral oil content of 5% to 50%.

⑷ Fully synthetic metalworking fluid without mineral oil.

What are the functions of metal processing fluids?

Lubrication function

The metal surface is subjected to a relatively large cutting force during the machining process, and there is relative movement, which will generate a large friction between the tool and the surface of the workpiece, and between the tool and the chips. The existence of this friction phenomenon will generate greater heat and aggravate the wear of the tool and the deterioration of the surface accuracy of the workpiece, and will reduce the processing efficiency. Metalworking fluids can greatly reduce this friction, extend tool life and improve the surface quality of processed parts. Generally speaking, the higher the mineral oil content in the metalworking fluid, the better the lubricating performance of the metalworking fluid. However, with the development of metalworking fluid technology, semi-synthetic and fully-synthetic metalworking fluids containing extreme pressure additives are also available. It also has good lubricating properties.

 Cooling function

This is also the reason why metalworking fluids are commonly referred to as "cooling fluids", because there are dual effects of shear and friction in the machining process, which will inevitably generate a large amount of heat. If this heat cannot be taken away in time, It will cause high temperature between the tool and the workpiece, which will soften the tool or even reduce the hardness of the workpiece surface, aggravate the tool wear, and affect the surface accuracy of the workpiece. Not only that, high temperature will also produce built-up edge, resulting in deviations in the machining accuracy of the workpiece. The flushing effect of the large flow metal working fluid can take away the heat generated in the machining process, reduce the temperature of the tool and the workpiece, extend the life of the tool, improve the surface accuracy of the workpiece, and improve the efficiency of machining.

Chip removal function

If the machining chips produced in the metal machining process cannot be removed from the machining area in time, it may produce built-up edge and cause wear of the machined surface.

Anti-rust function

Most metal materials (such as iron and cast iron) will quickly rust after being in contact with moist air and water. In the metal machining process, if between two different processes, the metal working fluid cannot provide good The anti-rust function may cause corrosion of the semi-finished product, which will cause the product to be scrapped.

In addition to the above functions, metalworking fluids must also have anti-foaming, environmentally friendly, and antibacterial functions. Different machining methods have different functional requirements for metalworking fluids. For example, heavy-duty and low-speed machining require more metal lubrication performance. High speed and low load machining have higher requirements for cooling.
