time passed when ordering metalworking consumables and evaluating and analyzing the coolant and lubricating oil remaining around the rags. Many companies have deeply realized that producing high-quality products in different ways is the foundation of enterprise survival

choosing the right coolant is not the only consideration for TXV aerospace composites. The decision to use the latest fiberforge laying system from German Dieffenbach company is the only consideration to achieve good cooling effect. If the coolant is not effectively transmitted according to the appropriate temperature and pressure, the coolant used does not use nozzles with correct positioning and shape, and the filter system used does not match the processing work, then the coolant provided in these cases may not play a role at all, or worse results will be produced

technology is not the only challenge facing coolant and lubricant suppliers. ITW rocolnorth America, an American lubricant giant, and most other suppliers are under pressure from rising basic inventory costs. This is a dual challenge, namely, the lack of oil and rising prices. In order to provide customers with the best solution to meet their needs, ITW ROCOL North America has continuously strengthened its close cooperation with customers. They have developed a dual route, providing both traditional splash coolant and coolant with micro lubrication (MQL) system

itw ROCOL North America developed accu lube series organic coolant/vegetable oil for MQL market for quasi dry cutting. Because this vegetable oil has many advantages, it can solve the inherent problems of water-based coolant, such as the need to repair the water tank and the need to deal with the coolant. Therefore, MQL has a very promising market prospect. For traditional splash cooling, the company recently tends to use bio stable semi synthetic coolant, such as rustlick ultracut 370r coolant

whether splash cooling mode or MQL mode is selected depends on specific processing parts. The key question is whether the liquid can be transported to the part processing area and to what extent the oil mist generated in the working environment is restricted. If the oil mist pollution is very serious, many changes will need to be made for customers and suppliers using metalworking coolant. Basic research on coolant

basic research has always been a research focus of Benz oil company, especially the surface chemical properties of lubricants under high pressure. For example, what happens when the tool contacts the workpiece? How to effectively use the chlorine, phosphorus and sulfur in the coolant to control the surface finish of the workpiece. It is also necessary to quantify how thin films are formed and what makes them form. Next, perhaps the most important problem is to understand how these chemical elements break the bonding between atoms on the surface of the workpiece material in a complex process, such as the bonding between iron atoms, and adopt the controlled splitting method to open the surface, so as to promote the material to fall off from the workpiece. These chemicals act as a high-speed hydrogen embrittlement agent, controlling friction by forming a thin film on the surface of the sliding contact area

basic research is closely related to the production process of coolant. In this process, its contact pressure reaches more than Gigabit PA (GPA), or a technician of our company will introduce the application precautions of 1 spring tension compression testing machine to you, which is related to the usual inspection points. At this point, plastic deformation of any level can occur. The use of vegetable oil

the rising price of oil has become a problem that cannot be ignored in grinding operations. One of the reasons why solvent refined oil tends to be used is that it is not so sensitive to thermal shock. Thermal stability is very important for any precision grinding operation. Researchers found that under severe grinding conditions, water-based coolant will cause damage to the workpiece due to its thermal stability. Water will boil and evaporate on the cutting surface, causing the whole system to be in a dry grinding state. However, customers who prefer to use oil-based coolant must also understand the causes of oil mist, and also need to use a higher pressure flow system to remove oil mist

Blaser of Switzerland believes that vegetable oil is a huge market. Vegetable oil is not only environmentally safe, but also can improve production efficiency. In an application case, Basso engineers saved 30% of the production cycle after using vegetable oil. They found that the application of vegetable oil in more difficult processing environments can obtain the highest production benefits. For example, using vegetable lubricants in titanium alloy processing can obtain higher benefits than processing aluminum. Vegetable oil has polarity, which enables vegetable oil additives to effectively form a fine and evenly distributed surface

after Basso's customers began to use vegetable oil-based products, they have repeatedly praised their ability and benefits in improving production efficiency, and they are used more frequently and processed faster

in addition, vegetable oil can be discharged from the machine tool together with chips, and the quality of parts processed and produced is better, which can also save 20% - 30%. This also makes up for the cost gap between the use of mineral oil and vegetable oil to a certain extent. Because if only from the perspective of price, the price of vegetable oil-based cutting coolant used in the initial stage can jump by $5 to $9 every time it is added to Jinan assaying Sales Department, which is not a small expenditure for production enterprises. Another advantage of vegetable oil is that most vegetable oil has a higher flash point than mineral oil, which obviously has higher safety for those customers who have been using oil products

Basso has also made remarkable achievements in the research of high-pressure coolant and cutting oil devices. They have developed a coolant that can control foam and gasification, which can enable customers to fully enjoy the advantage of improving productivity brought by high pressure. When selecting a suitable metalworking coolant for high-pressure applications, the water quality, the size of the water tank, the cycle time, the configuration of the water pump, the pressure and the transmission of coolant through the tool are all important factors to be considered. Selection of coolant filter

coolant filter plays a very important role in the performance of coolant. Mr. Andy Nelson, product application manager of American Masdar chemical company, believes that the filter should make the circulating particles in the filtered coolant not greater than 10% of the tolerance range. For example, if the tolerance range is 0.13 mm, select a filter that can reliably remove particles larger than 0.0025 mm to ensure that the scratches or accumulated errors left by the chips do not affect the tolerance requirements. If a high surface finish is required, even a small scratch will affect the surface quality and measured value. And over time, particle accumulation will also occur on the filter. Therefore, it is very necessary to regularly remove the accumulated particles in the coolant, because they will cause unnecessary chemical reactions in the coolant, which will affect the surface finish

in grinding, the coolant can quickly wet the grinding wheel, and the grinding wheel has become a rapidly moving sea digital display electronic universal experimental machine. It can read the cotton body from the digital display or computer, and bring the coolant to the contact arc surface for cooling and lubrication. The more coolant the grinding wheel can absorb, the stronger the ability of coolant to reduce parasitic resistance. The residue deposited on the grinding wheel also has a great impact on the grinding wheel. Therefore, we must pay attention to maintaining the standard size of the grinding wheel, dressing and cleaning the grinding wheel normally, and removing the small particles deposited on the grinding wheel. Some of these residues are minerals contained in mixed hard water, and the other part comes from residual oil

the cations in the residues, especially magnesium ions and calcium ions, will react chemically with the wetting agent in the coolant, producing a soft oily residue that adheres to the surface of the grinding wheel, reducing the ability of the grinding wheel to absorb the coolant. In addition, this chemical reaction will also reduce the content of wetting agent in the coolant, thus affecting its ability to effectively wet the grinding wheel. A similar situation will also occur if an excessive amount of common theme anti foam agent is added to the coolant, in which the main active ingredient is an oily substance insoluble in water (generally one or more siloxane compound emulsions). These problems can often occur at any time when using a hard closed grinding wheel with a very small particle size. Oil mist control

the amount of mineral oil allowed in oil mist in metal processing plants may be changeable. The American Committee of governmental industrial hygienists (ACGIH) recommended that the oil mist limit be 0.2 mg/m3. Although ACGIH is not a regulatory agency, the U.S. Occupational Safety and Health Administration (OSHA) accepted their recommendations

once this new restriction takes effect, it will certainly affect equipment manufacturers and end users, and a lot of improvements need to be made to the equipment. This means that more synthetic liquids can be used, and the system is required to have better control function of oil mist. In theory, vegetable oil will not be included, so its use may increase

the reasons for the preference for vegetable oil processing are the rising price of oil and the greater use of high-pressure lubricants and lubricants through knives. Vegetable oil has stronger anti foam formation characteristics, stronger anti microbial characteristics and stronger biological stability

the use of high magnesium alloys and low magnesium alloys is increasing, especially in the automotive industry, because this material has excellent strength to weight ratio

due to this development trend, other related metalworking coolants have been introduced. Magnesium is an active metal, which can release hydrogen when contacting with water, which is easy to cause fire or explosion. Therefore, the coolant used in magnesium alloy processing should be prohibited from such reactions, which should be paid enough attention. Coolant and grinding
