According to the survey, the most common issues reported by metal manufacturing manufacturers in the daily processing and use of cutting fluids include: "Odor, deterioration, rust on parts, etc.". The arrival of summer has once again raised concerns about the odor of cutting fluid.
The reason why cutting fluid is prone to odor is mainly due to temperature. In some places, the temperature is generally around 30 degrees Celsius, which is very conducive to the growth of cutting fluid bacteria. However, with more bacteria, cutting fluid will naturally experience odor and deterioration. To prevent the odor and deterioration of cutting fluid, we first need to understand the main channels through which bacteria enter the cutting fluid. Firstly, in the process of cutting fluid production, if it is emulsified oil and the water used to prepare emulsified oil contains bacteria, then the cutting fluid prepared will naturally contain bacteria. Secondly, during the preparation process of cutting fluid, if it comes into contact with air, 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 process of cutting fluid. Therefore, in the process of using cutting fluid, such as the operation of workpieces, the bad habits of operators, the cleanliness of the workshop, and the cleanliness of the sink and water tank, the impact of bacteria in the cutting fluid is very significant.
So how can we prevent the problem of cutting fluid odor and corrosion? For metal processing and cutting manufacturers, this problem should be prevented from the source. So when choosing cutting fluids, it is important to choose high-quality and biologically stable cutting fluids.
In the process of using cutting fluid, to prevent the odor and deterioration of the cutting fluid, the following points need to be done well: Firstly, regularly use a refractometer to test the concentration parameters of the cutting fluid. Due to the high concentration, cutting fluid can easily cause allergies to the skin of operators. If the concentration is too low, it can cause a large amount of bacterial corrosion. Secondly, minimize the mixing of oil leaked from the machine tool with cutting fluid, as the oil used in the machine tool contains bacteria. Thirdly, when the pH value of the cutting fluid is too low, new cutting fluid should be added in a timely manner to increase the pH value. When the pH value of the cutting fluid is between 8.3-9.2, bacteria are difficult to survive. Fourthly, do a good job in cleaning the workshop environment, and do not allow cutting fluid to come into contact with dirt such as oil, food, tobacco, etc. Fifth: Provide training on the operation and maintenance of workers using cutting fluid.
