What should I do if the cutting fluid stinks? Five tips to let you say goodbye to smelly cutting fluid completely!

According to the survey, in the daily processing and use of cutting fluid, the most frequently reported problems by metal manufacturers include: “Cutting fluid smells, deteriorates, parts rust, etc.”. With the arrival of summer, the odor problem of cutting fluid has once again attracted attention.
The reason why cutting fluid is easy to stink in summer is mainly due to the temperature. The temperature in some places is basically more than 30 degrees, which is very conducive to the growth of cutting fluid bacteria, and cutting fluid will naturally appear if there are too many bacteria. Smelly and spoiled. To prevent the odor and deterioration of the cutting fluid, first of all, we need to understand the channel through which bacteria enter the cutting fluid.
First: in the process of cutting fluid production, if it is emulsified oil and the water in which the emulsified oil is prepared contains bacteria, then the prepared cutting fluid will naturally contain bacteria.
Second: When the cutting fluid is in contact with the air during the preparation process, the bacteria in the air will also enter the cutting fluid. In addition to the above two points, there may be contact with bacteria during the preparation of cutting fluid. In the process of using cutting fluid, for example: the operation of workpieces, the bad habits of operators, the cleanliness of the workshop, the water tank The cleaning of the water tank has a great influence on the bacteria in the cutting fluid.
So how can we prevent the odor and corrosion of cutting fluids? For metal processing and cutting manufacturers, it is necessary to prevent this problem from the source. Therefore, when choosing cutting fluids, you should choose some high-quality cutting fluids with good biological stability.
In the process of using cutting fluid, to prevent the odor and deterioration of cutting fluid, the following points need to be done:
First: regularly use a refractometer to test the concentration parameters of the cutting fluid. Because the concentration is too high, the cutting fluid is easy to cause allergy to the skin of the operator. If the concentration is too low, it will cause a lot of corrosion of bacteria.
Second: Minimize the oil leaked from the machine tool to mix into the cutting fluid, because the oil used in the machine tool contains bacteria.
Third: When the pH value of the cutting fluid is too low, new cutting fluid should be added in time to increase the pH value. When the pH value of the cutting fluid is between 8.3 and 9.2, it is difficult for bacteria to survive.
Fourth: Do a good job in cleaning the workshop environment, and do not let the cutting fluid come into contact with dirt such as dirty oil, food, and tobacco.
Fifth: Do a good job in the operation and maintenance training of workers using cutting fluid.
