What to do if the cutting fluid stinks during metal processing

The cutting fluid stinks after being used for a period of time, in fact, because the microorganisms in it exceed the standard, generally the sixth power of 10 is the critical value, higher than this value, the smell is obvious. There are three ways to solve this problem. First, replace the cutting fluid, which everyone can think, but it is not economical, and the production cost is increased, second, a certain proportion of the new ratio liquid is added to the cutting fluid, so that the microbial content is reduced to 10 to the sixth power, and the third, the use of sterilization and deodorization equipment, conventional ultraviolet, ozone sterilization, or the use of Lu Hong'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 the amount of consumables.

The main cause of the odor of cutting fluid is excessive microorganisms (bacteria, fungi, etc.). To solve this problem, it is necessary to keep the cutting fluid as clean as possible and maintain the pH value of the cutting fluid.

The above measures can reduce the number of microorganisms to a certain extent, but they cannot completely eliminate the microorganisms, and further sanitizing treatment is required. Disinfectants such as Octex Oxytech D-50 500 can be added to the cutting fluid in proportion to achieve the desired sterilization effect.

High-quality, stable cutting fluids are used.

Concentrate with pure water is not only easy to formulate, but also improves the lubricity of the cutting fluid, reduces the amount of chips carried away, and prevents bacterial erosion.

When using, it is necessary to control the ratio of concentrate in the cutting fluid should not be too low, otherwise it is easy to cause bacteria to grow.

Since the oil used in the machine tool contains bacteria, it is necessary to minimize the oil leakage from the machine tool and the mixing of the cutting fluid.

When the pH value of the cutting fluid is high, it is difficult for bacteria to survive, so new cutting fluid should be added in time to increase the pH value.

Keep the cutting fluid clean and do not let the cutting fluid come into contact with dirt such as oil, food, tobacco, etc.

Fungicides are often used.

Keep the workshop and machine tool clean.

If the equipment does not have a filtration device, the oil slick should be skimmed off regularly to remove the dirt.

Corrosion problems of cutting fluids.

In the process of using cutting fluid, in order to prevent the odor and deterioration of cutting fluid, the following points need to be done:

1. Use the refractometer regularly to test the concentration parameters of the cutting fluid. Because the concentration is too high, the cutting fluid is easy to cause allergies to the operator's **. If the concentration is too low, it will cause a lot of corrosion of bacteria.

2. Try to reduce the oil leakage from the machine tool mixed with the cutting fluid, and the tramp oil content in the cutting fluid is too high, which will breed bacteria.

3. When the pH value of the cutting fluid is too low, a new cutting fluid should be added in time to increase the pH value.

4. Do a good job of cleaning the workshop environment, and do not let the cutting fluid come into contact with dirty oil, food, tobacco and other dirt.

5. Do a good job in the operation and maintenance training of workers using cutting fluid.

6.Use cutting fluids with good stability.

If you want to avoid such embarrassment, you must first prevent it from the source, when choosing a cutting fluid, you should choose a cutting fluid with high quality, effective anti-bacteria and fungi, good oxidation resistance, and excellent stability with a long service life, our micro-emulsion titanium alloy cutting fluid fully meets this demand, in addition, all products of Tomeido have such characteristics, strong rust resistance, high lubrication, good extreme pressure, pressure resistance, etc.

Under normal conditions, the contact between the workpiece and the tool produces high temperatures. One of the functions of cutting fluid is cooling. Under the action of cutting fluid, the temperature of the workpiece decreases, and there will be a slight smell, but it should not be very large, let alone pungent.

Since many cutting fluid products are now organic, they will produce odors, and there will be pungent odors. At this time, the cutting fluid begins to deteriorate.

It is recommended to check the cutting fluid and replace it.

When machining parts at the airport, due to the high temperature generated by the contact cutting between the tool and Mao Pei, the temperature of the workpiece is very high, and the cutting fluid is poured on the workpiece and props, and due to the high temperature, a part of the cutting fluid vaporizes into the air and goes to your nose! As for the composition and formula of the cutting fluid, there are many!
