According to the survey, the most common problems reported by metal manufacturing manufacturers in the daily processing of cutting fluids include: "cutting fluid stinks, deteriorates, parts rust, etc." With the arrival of summer, the problem of cutting fluid stinking has once again attracted attention.

The reason why cutting fluids are prone to stink in summer is mainly due to temperature. The temperature in some places is basically more than 30 degrees, which is very conducive to the growth of cutting fluid bacteria. If there are too many bacteria, the cutting fluid will naturally stink and deteriorate. To prevent the problem of cutting fluid stinking and deterioration, we must first understand the main channels through which bacteria enter the cutting fluid.
First: In the process of cutting fluid production, if it is emulsified oil, and the water used to prepare the emulsified oil contains bacteria, then the prepared cutting fluid will naturally have bacteria.
Second: If the cutting fluid comes into contact with air during preparation, 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, bad habits of operators, cleanliness of workshops, and cleanliness of sinks and water tanks all have a great impact on the bacteria in cutting fluid.
So how can we prevent the problem of cutting fluid odor and corrosion? For metal processing and cutting manufacturers, to prevent this problem, we must prevent it from the source. Therefore, when choosing cutting fluid, we should choose some high-quality cutting fluids with good anti-biological stability.
In the process of using cutting fluid, to prevent the problem of cutting fluid odor and deterioration, we need to do the following:
First: Use a refractometer to test the concentration parameters of cutting fluid regularly. Because the concentration is too high, the cutting fluid is easy to cause allergies to the operator's skin. If the concentration is too low, it will cause a lot of bacterial corrosion.
Second: Try to reduce the mixing of oil leaked from the machine tool into the cutting fluid as much as possible, because the oil used by 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, bacteria are difficult to survive.
Fourth: Keep the workshop environment clean and do not allow the cutting fluid to come into contact with dirty oil, food, tobacco and other contaminants.
Fifth: Provide training for workers on the operation and maintenance of cutting fluids
