What to do if the cutting fluid smells bad during metal processing

If the cutting fluid smells after being used for a period of time, it is actually because the microorganisms in it exceed the standard. Generally, 10 to the sixth power is the critical value. Above this value, the odor will be obvious. To solve this problem, there are three ways. First, replace the cutting fluid. Everyone can think of this, but it is uneconomical and increases production costs. Second, add a certain proportion of new fluid to the cutting fluid to reduce the microbial content to less than 10 to the sixth power. Third, use sterilization and deodorization equipment. Conventional ones include ultraviolet and ozone sterilization, or use Luhong's cell wall-breaking technology to kill microorganisms. The advantage of this method is that after the cutting fluid is deodorized, the cutting fluid can be reused, saving consumables.
