According to the survey, when cutting fluids are used in daily processing, the most common problems reported by metal product manufacturers are: “cutting fluid smells, deteriorates, and parts rust, etc. ” With the arrival of summer, the problem of cutting fluid odor has once again attracted attention.
The reason why cutting fluid tends to stink easily in summer is mainly due to temperature. The temperature in some places is basically above 30 degrees, which is very conducive to the growth of cutting fluid bacteria. If there are too many bacteria, the cutting fluid will do it. naturally appear smelly and spoiled. To avoid cutting fluid odor and spoilage, we must first understand the main channels through which bacteria enter the cutting fluid.
First: In the process of producing cutting fluid, if it is emulsified oil and the water used to prepare the emulsified oil contains bacteria, then the prepared cutting fluid will naturally contain bacteria.
Second: When the cutting fluid comes into contact with air during the preparation process, bacteria in the air also enters the cutting fluid. In addition to the above two points, in the process of preparing cutting fluid, there may be contact with bacteria when using cutting fluid, for example: operation of parts, bad habits of operators, the cleanliness of the workshop. , the sink Cleaning the water tank has a great impact on the bacteria present in the cutting fluid.
So how can we prevent cutting fluid odor and corrosion problems? For metal processing and cutting manufacturers, we need to prevent this problem at the source. Therefore, when choosing cutting fluid, you should choose cutting fluid of high quality and good antibiological stability.
When using cutting fluid, to avoid odor and deterioration of the cutting fluid, the following points must be observed:
First: Use a refractometer to regularly test the cutting fluid concentration parameters. Due to too high a concentration, cutting fluids can easily cause skin allergies in operators. If the concentration is too low, it will cause massive corrosion by bacteria.
Second: Minimize the oil leakage from the machine tool to mix with 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 cutting fluid is between 8.3 and 9.2, it is difficult for bacteria to survive.
Fourth: Do a good job cleaning the workshop environment and don’t let the cutting fluid come into contact with dirty oil, food, tobacco and other contaminants.
Fifth: Provide operation and maintenance training to workers on the use of cutting fluid.
