How to prevent cutting fluid from freezing How to prevent cutting fluid from freezing

1. Cutting fluid.

When using, the water tank, pipes and other parts that come into contact with the slurry should be cleaned first.

2. It is recommended to use the original solution without adding water. It can also be done by adding a small amount of diethylene glycol.

The freezing point can be lowered.

3. The oily cutting oil can be replaced, and antifreeze can also be added to the cutting fluid to prevent the cutting fluid from freezing.

1. The cutting fluid should be replenished in time during use, and the overall processing environment in winter is not particularly good, so we should pay attention to the changes in the cutting fluid and replenish the cutting fluid in time to help us play the role of the cutting fluid.

2. You can consider replacing the cutting fluid with a relatively low freezing point, or adding appropriate antifreeze to the original cutting fluid, so as to maintain the effect of the cutting fluid.

3. Some external heating equipment, such as heaters, can be used to maintain the appropriate temperature of mechanical equipment, which can also help us better processing, and the use of cutting fluid will not affect too much.

Ways to prevent cutting fluid from freezing:

1. First of all, it depends on the specific ambient temperature.

If the overall ambient temperature is low, then it is advisable to use a cutting fluid with a lower freezing point, and some brands of cutting fluid have antifreeze added to it, which can be applied at a lower temperature so that it does not freeze.

2. If only a certain piece of equipment is located outdoors and other special reasons, resulting in a low temperature of the equipment, but the cutting fluid cannot be configured separately for this equipment, you can consider adding heaters and other devices to change the temperature. Wire EDM equipment can be used in this way. It depends on your equipment and operating conditions.

Cutting fluid does not have the function of anti-freezing, but it has the functions of lubrication, cooling, cleaning, rust prevention and so on.

1. Lubrication: In the grinding process, after adding grinding fluid, the grinding fluid penetrates into the grinding wheel, the abrasive workpiece and the abrasive grain between the grinding chip to form a lubricating film, so that the friction between the interface is reduced, and the abrasive cutting edge is prevented from wearing and sticking to the chips, thereby reducing the grinding force and friction heat, and improving the durability of the grinding wheel and the surface quality of the workpiece.

2. Cooling: The cooling effect of cutting fluid is to take away the cutting heat from the tool and the workpiece through the convection and vaporization between it and the tool (or grinding wheel), chip and workpiece that are heated due to cutting, so as to effectively reduce the cutting temperature, reduce the thermal deformation of the workpiece and the tool, maintain the hardness of the tool, and improve the machining accuracy and tool durability.

3. Cleaning: The water-based cutting fluid containing surfactant has a good cleaning effect, because it can form an adsorption film on the surface to prevent particles and sludge from adhering to the workpiece, tool and grinding wheel, and at the same time, it can penetrate into the interface where particles and sludge adhesion, separate it from the interface, and take it away with the cutting fluid to keep the interface clean.

4. Anti-rust: When the workpiece is temporarily stored after processing or during the circulation between processes, the cutting fluid is also required to have a certain anti-rust ability to prevent the corrosion of the metal by corrosive substances such as environmental medium and oil sludge in the residual cutting fluid. Especially in the humid and rainy season in southern China, more attention should be paid to anti-rust measures between processes.

Nowadays, almost all cutting fluids can be anti-freeze, such as the green cutting fluid of American companies we use, if there is no anti-freeze, the cutting fluid also has additives that reduce the freezing point, even if there are many parts of water, it can also be improved.

Liannuo SCC750A stainless steel cutting fluid is made of special high-performance extreme pressure additives, rust inhibitors and other additives, which can form a stable transparent light yellow solution when mixed with water. It has good extreme pressure lubricity, rust resistance, cooling, settling and cleaning properties. It has strong anti-microbial decomposition ability and can maintain its stability under different water hardness conditions, and is a new generation of high-performance multi-purpose foam-free grinding fluid.

There is definitely no problem with adding some antifreeze, and the machining center is still good at more than 20 degrees, and the accuracy is not good if it is frozen.

You're so cold. Generally, the suitable temperature of the machining center requires a constant temperature of about 20 degrees, otherwise the accuracy will be affected.

There are 2 ways to solve your problem:

First, it is recommended to use cooling oil.

Second, add antifreeze to the cutting fluid. I don't know if this approach is feasible or not. Because, the coolant circulation circuit is open, there will be volatile, I don't know how volatile the antifreeze is; Do coolant and antifreeze react?

In addition, what will be the effect of antifreeze heating on the surface of the workpiece, and will it affect the processing? None of this is clear.

1. Generally, there will be no icing problem in the process of use, and the temperature in the workshop will be higher than -10 no matter how low it is, and the general working fluid can reach the following freezing point.

2. In the process of storage and transportation of the stock solution, the climatic conditions of -20 to -30 may be encountered, so some alcohols will be added to the general synthesis, and the inorganic salts will also reduce the freezing point, so there will be no freezing problem normally. Even if it freezes, the quality of the product in general will not be affected. If the product you are using freezes, it means that the product is still not up to par.
