What Are Metalworking Fluids?

Metalworking fluids are mainly liquids used for metal processing. They are mainly used for lubrication and cooling, as well as for 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, rust preventive oils, cleaning agents, blackening agents, drawing oils, thickening Agent. Metalworking cutting fluid is a low-foam, high-lubricity soluble lubricating oil. It can reduce maintenance costs to a minimum even when it is used in environments where machining fluids are required. It can basically be applied to all types of metals and alloys. Type of processing, it is very effective for the general processing of most ferrous metals, especially in the processing of mild steel, cast iron, stainless steel and other special steels can simultaneously play an excellent lubrication and cooling effect.

Metalworking fluid

(Processing liquid)

If the operation mainly requires heat removal and temperature reduction, then the metalworking cutting fluid can be formulated into a low-concentration working fluid; if soft, viscous materials are to be processed, or a large amount of friction is required to reduce friction during low-speed processing, metal cutting can be cut The liquid is formulated into a high-concentration processing fluid. We think that 7-10% is the concentration that is most suitable for tank storage and also can exert the best performance. In addition, if it is grinding, it is generally recommended to use a concentration of 3-5%

Metalworking cutting fluid has stable and outstanding performance, and can be applied to various cutting and grinding operations of various materials (including non-metallic materials, such as ceramics, silicon wafers, etc.). The good chemical lubricity and mechanical lubricity of the product can meet the most demanding cutting and grinding processing requirements, and it is the best choice for manufacturers of high-volume and high-quality parts.

This product is basically suitable for all types of processing of various metals and alloys. It is very effective for the general processing of most ferrous metals, especially when processing mild steel, cast iron, stainless steel and other special steels. Lubrication and cooling.

With the continuous development and progress of industrial technology, new materials and new processes are constantly emerging. Selecting the appropriate cutting fluid in these processing processes is crucial to ensure product processing quality, improve processing efficiency, and reduce environmental pollution.

Metalworking fluids are also commonly called "cooling fluids". According to different machining requirements, metalworking fluids can be divided into cutting fluids and grinding fluids. In the manufacturing industry, the use of metalworking fluids is very wide. For example, in the machining of engines and gearboxes, the equipment manufacturing industry, and the gear industry, various metalworking fluids are widely used.

Metal processing includes rolling, forging, die stamping, drawing, forming, cutting and grinding. Most metal processing relies on good metalworking fluids, so the amount of metalworking fluids is large, including fatty acid soaps, hydrocarbon oils, emulsified oils and aqueous solutions. With the increase of metal processing requirements, synthetic oils and synthetic metal working fluids need to be used in many cases to improve the quality of metal processing. Currently, synthetic lubricants used in metalworking fluids include polyalkylene glycols, esters, synthetic hydrocarbons, and other synthetic lubricants.

Classification of metalworking fluids

Metalworking fluids are complex and complex. 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 also commonly called water Base metal working fluid. Metalworking fluids are usually classified by the content of mineral oil: ^[2]

Metal processing oil (liquid) is of low grade and has a large gap with foreign countries. China has a long history of applying metal processing oil (liquid). Drawing, extrusion, die punching, rolling, forging and other metal processing oils, process technology and product quality, variety development is slow. At the end of the 1980s, domestic metal processing oil (liquid) demand was about 10 kt / a. In the 30 years of reform and opening up, China has gradually become the world's manufacturing plant. At present, it has more than 4 million metal cutting machine tools, with a total demand of about 400kt / a. China's metal processing oils (liquids) are mainly low-grade, and there are few high-grade oils. They mainly rely on imports. There is a certain gap between domestic product quality and foreign oil products.

In addition, there are several reasons for the import of high-grade oil:

The main reason is that foreign equipment manufacturers have contracts with oil suppliers. The equipment produced by equipment manufacturers must use the special oil provided by the oil supplier, and their interests are mutually beneficial.

It is difficult for domestic enterprises that have introduced equipment to accept domestic alternative oils. They are worried that the oil quality will not meet the technical requirements, damage large-scale equipment, and cause serious economic losses to the enterprise.

(3) The simulation test and bench test cannot meet the test requirements. Relevant domestic experts conduct research based on the nature of imported oil samples. Although the physical and chemical indicators can reach the quality level of imported oil, due to the lack of key simulation tests and bench tests, the alternative special oils developed cannot be mass-produced, which has inhibited metal processing in China. Development of oil (liquid).

2 Quality standards and test methods lag

The domestic metal processing oil (liquid) quality standards and test methods have done a lot of work in line with international standardization, and have made great progress, but the quality standardization and test method formulation are behind and cannot keep up with the development of the mechanical processing industry. With the rapid development of new technologies in the mechanical processing industry, there are many types of metal processing oils (liquids) and their compositions vary greatly. In China, metal processing oils (liquids) are classified as process oils. There are few national standards and industry standards. Many metal processing oils (liquids) do not have quality and technical indicators. China has joined

Metalworking fluids basically cover most liquids used in metalworking, such as emulsified metalworking fluids, semi-synthetic metalworking fluids, fully synthetic metalworking fluids, metalworking oils, etc., which are all metalworking fluids. As for the use of metalworking fluids, China Metalworking Fluids Network will introduce them to all metalworking manufacturers.

First: Although there are many types of metalworking fluids, the methods used are mostly the same. For water-soluble metalworking fluids, it is necessary to dilute by adding water. As for the ratio of metalworking fluid to water, Ask the supplier who provided us with metalworking fluids. We need to pay attention to the fact that the quality of the water added must meet the requirements of metalworking fluids, because water is also divided into hard water and soft water.

Second: The use of metalworking oils is not the same as the use of metalworking fluids. Metalworking oils can not be added with water, and they can be used directly without adding water. No further dilution is required during use. However, in metal processing, it is necessary to select a metal processing oil with a concentration required for load processing according to the materials, methods and requirements of its own processing.

Third: Whether it is metalworking fluid or metalworking oil, when it is stored, it must be stored in a cool and dry place to avoid direct sunlight. Follow the principle of first in, first out.
