  When using a metal circular saw, we know to check whether the cutting fluid used by the machine is normal-can it be used when cutting materials. But do you know what effect the cutting fluid will have on the circular saw? What is the role of the PH value in the cutting fluid?

  Generally, when the metal circular saw is cutting, the cutting fluid plays a role in protecting the saw blade of the machine and ensuring the flatness of the cutting surface. The pH value in the cutting fluid shows the pH of the solution, which is divided into 0-14, the pH value is 7 for neutral, and the pH value is less than 7 for acidity. The smaller the pH value, the stronger the acidity. More than 7 is alkaline, the greater the alkaline, the stronger the alkaline. Under normal circumstances, most metalworking fluids should be alkaline. The pH value of newly prepared and unused metal working fluid (with a concentration of 5%) is generally between 8.5 and 9.5, and the most common pH value of modern metal working fluid is between 8.8 and 9.2.

  In metal processing, the pH value of the cutting fluid we normally use is usually between 8.0-9.5; if the pH value of the cutting fluid is greater than 9, the cutting fluid is irritating to human skin, causing skin allergies to the operator And non-ferrous metal corrosion; it will also reduce the lubricating performance of the cutting fluid, reducing the efficiency of production and processing. When the pH value of the cutting fluid is lower than 8, it indicates that the solution is invaded by bacteria, which is easy to multiply bacteria, causing the cutting fluid to decay on the workpiece and the machine tool, which will reduce the rust and corrosion resistance of the cutting fluid, and reduce the service life of the processed workpiece. And production efficiency.

  In addition, we can check the pH of the cutting fluid regularly (for example, use a pH test paper or a pH meter to detect the pH of the cutting fluid) to prevent the sudden drop or rise of the pH of the cutting fluid during metal processing, and avoid operators The use of safety; protect the normal operation of the cutting fluid in metal processing to achieve lubrication, cooling, rust prevention, and cleaning performance. It is also conducive to the maintenance of the cutting fluid, preventing the cutting fluid from being invaded by bacteria and ensuring that the workpiece does not rust, and at the same time does not corrode the circular saw machine tool and the tool.
