(Using descending order, does not include the effect of additives) Lubrication Cooling Pure oil composition Soluble oil semi-synthetic semi-synthetic Soluble oil composition Pure oil Pure oil Insoluble pure oil is from oil (mineral oil), animal or Derived from vegetable oils can be used "directly" without dilution with water. These oils have good lubricity and rust resistance, long oil tank life, and ease of maintenance. In addition, they do not deteriorate because organisms generally survive only in aqueous fluids. The neat oil may be a mixture of one or more different base oils and may contain boundary and/or extreme pressure additives such as sulfur, phosphorus or chlorine compounds and the like. Pure oil can reduce the force generated when the tool cuts metal, so the tool can clean cut and form a smooth surface on the workpiece. Additives can increase the lubricity of pure oils and strengthen the mat between the cutting metal and the tool. In extreme processing situations, additives may exceed 20% of the product composition. Although they are more expensive than similar products without any additives, they are important processes for surface roughness and tool life such as extrusion grinding, demanding processes, tapping and deep hole drilling, etc. with additives. Pure oil has a crucial role. In addition, pure oil can also prevent microscopic bonding during heavy-duty processing, and additives can improve the anti-adhesive properties of metals. However, pure oil is not flame-retardant and produces smoke, thus creating an operator-unfriendly processing environment. Pure oil may also leave an unpleasant film of oil on almost every surface of the factory. Soluble oil Soluble oils are suitable for light to heavy negative processing operations, including non-ferrous and ferrous metal processing. Wetting agents and extreme pressure additives can extend the range of use of soluble oils to include more heavy-duty processing processes that typically use pure oils. Soluble oils are usually either classified as semi-synthetic or classified as truly soluble, based primarily on the content of the oil used in the concentrate. Soluble oil concentrates contain 40% or more of the oil and these are mixed with water to form metal cutting fluids. These cutting fluids provide cooling due to oil and water mixing - water has a high heat capacity and dissipates heat well - - Encapsulation capability is achieved by mixing oil and water, which also typically leave a protective coating on the moving parts of the machine. Although soluble oils provide high quality lubricants that can extend tool life, they do not always have the same level of lubricity as pure oils. They also require more maintenance than pure oils. The use of water makes the history of soluble oil prone to microorganisms and is more prone to spoilage. Therefore, processing plants must adhere to strict preventive maintenance measures to extend the life of their tank. Operators need to closely infuse and type of water that can dissolve the soluble oil platform. If mixed with hard water, the soluble oil can precipitate on the workpiece and the machine tool: groundwater may be hard and may contain accelerated chloride ions or sulfates. Machine shops should use state-of-the-art coolants with adequate corrosion protection, or they may need to add oil tank preservatives to the coolant. On the other hand, machining using soft water and soluble oil-based coolants may have problems with foams and therefore require the use of oil sump additives such as defoamers. Semi-synthetic coolant The semi-synthetic coolant is formulated by adding up to 40% of petroleum to the water dilutable concentrate. It is also possible to add additives such as emulsifiers, wetting agents, preservatives, extreme pressure ingredients and insecticides. These coolants are generally translucent but may also be transparent or completely opaque. Semi-synthetic coolants can be used on a wide range of tools. They provide good lubrication for medium and heavy loads. Through them, operators can cut at higher speeds and feeds because they generally have better cooling and wetting properties than soluble oils. Semi-synthetic coolants are formulated with less oil, sometimes with better settling and cleaning performance. Because they contain less oil than pure or soluble oils, they produce less dust. The disadvantages of semi-synthetic coolants are similar to those of soluble oils - water hardness affects its stability. Mixing hard water and water compounds may cause hard water deposits to form in the tank, and mixing with soft water will produce foam. Synthetic coolant synthetic coolant does not contain petroleum base oil. Usually, they contain water-insoluble lubricants and rust inhibitors. The supplier provides the composition in the form of a concentrate, much like a soluble oil, which is mixed with water to form a cooling liquid. Because of the additives and the water added to the concentrate, the composition has a high cooling function. At the same time they are best used for high heat and high speed metal cutting, such as surface grinding. Additives have a profound effect on lubricity and, when added to certain compositions, can produce better lubricating effects than pure oils without additives. Heavy-duty composites have been fully developed in the past few years and can now handle most of the additions. Synthetic coolants can be divided into several classes based on their composition: Simple cutting fluids are used for light load grinding operations. They mix in an oil sump to create a clear liquid so the operator can see the metal being cut. The complex cutting fluid contains synthetic lubricants for medium/heavy duty cuts that can be performed at high speeds. They also form a clear solution in the oil bath. Emulsifiable cutting fluids contain chemicals that form specific lubricating oil characteristics and look similar to soluble oils. The composition has the ability to prevent complete acid degradation and generally has good microbial inhibition. Most of the composition is used for preservation and it has outstanding cooling ability. Traditionally, synthetics have many drawbacks. Compositions are usually more expensive than their oil counterparts. In addition, some of the compounds run very cleanly. That is, its properties as a cleaning agent can cause certain compositions to cause failure of the machine seal, drying of the operator's skin and mucous membranes. Many synthetic coolants leave sticky, sticky residues. Some people believe. Synthetic agents are not easy to atomize, but this is not necessarily true. Depending on their composition and operation, they may not produce oil mist, such as soluble oil, but they may still be oil atomized, causing inflammation of the nose, throat, and intraocular mucosa. Because they are oil-free, the composition may cause more damage to human skin. Advice on proper coolant selection The best coolant protects the machine tool and prolongs tool life while providing the operator and environmental health and safety approvals. Choosing the best coolant to optimize all parameters is best done based on the recommendations of the machine tool manufacturer and the coolant supplier. Plant operators and engineers often rely on the coolant supplier's proprietary knowledge to discuss and recommend the best coolant for the material being processed. Most factories want to minimize the type of coolant used to reduce the cost of coolant maintenance and disposal, and can purchase coolant in large quantities to further save expenses. Some machine tool manufacturers require specific coolants for their products. A large number of machine tool manufacturers provide a recommended coolant meter and stipulate that if the user does not use the recommended coolant, the warranty will be void. When the processing plant is considering purchasing a machine tool, it should find the machine tool manufacturer and specify the coolant that is currently used in the workshop. Then, manufacturers and coolant suppliers can work together to determine how effective the existing coolant will be in various new machines.

Coolant effect
Other features of the coolant include cleaning chips, preventing corrosion, ensuring biological stability, and providing an operator-friendly environment. The coolant is a combination of complex chemical formulations to meet these specialized performance requirements. Machine shops often have many different machining operations, each with their own specific coolant requirements. In order to meet these requirements, the coolant formulation has spawned hundreds of products with different functions. In the past, machine shops were often prepared to use different coolants on site to meet the engineer's requirement for using Kumaga's coolant for each machine. However, different cooling fluids in the processing plant cause problems such as cross-contamination and waste liquid incompatibility. In addition, a variety of coolants also caused an increase in inventory. Today, machine shops tend to use one or a limited number of coolants for all processes in the shop. This approach has prompted coolant suppliers to develop more comprehensive products that help solve problems such as cooling, lubrication, corrosion protection, and microbial control while manufacturing good products. With so many processes and a large number of coolant types on the market, machine shops have encountered complex challenges in selecting the best and most economical coolant for their operation. In addition, for the problem of the best coolant for each specific process, there is always a phenomenon where the beholder sees the wise. A basic understanding of how the various components of the three main types of coolants—pure oils, soluble oils, and synthetics—has impact on performance, and makes the choice of coolant easier.
