According to the survey, in the daily processing and use of cutting fluid of CNC cutting tools, the most frequently reported problems by metal manufacturers include: “cutting fluid stinks, deterioration, rusting of parts, etc.”. The problem of the smell of cutting fluid in the summer has once again attracted attention.

The reasons for the cutting fluid bad smelling

The reason why the cutting fluid is easy to smell in summer is mainly due to the temperature. The temperature in some places is basically more than 30 degrees, which is very conducive to the growth of cutting fluid bacteria, and the cutting fluid will naturally appear when there are more bacteria. It stinks and deteriorates. To prevent the odor and deterioration of the cutting fluid, we must first understand the channels through which bacteria enter the cutting fluid.

In the process of cutting fluid production, if it is emulsified oil, the water used to prepare the emulsified oil contains bacteria, then the prepared cutting fluid will naturally contain bacteria.

When the cutting fluid is in contact with the air during the preparation process, the bacteria in the air will also enter the cutting fluid. In addition to the above two points, in the cutting fluid preparation process, there may be contact with bacteria. Then in the process of using the cutting fluid, for example: the operation of the work piece, the bad habits of the operators, the cleanliness of the workshop, the sink The cleaning of the water tank has a great influence on the bacteria in the cutting fluid.

So how do we prevent the odor and corrosion of cutting fluid? For metalworking manufacturers, this problem must be prevented from the source. Therefore, when choosing a cutting fluid, you should choose some cutting fluids with high quality and good biological stability.

The solutions for preventing the cutting fluid being stinky

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

Regularly use a refractometer to test the concentration parameters of the cutting fluid. Because the concentration is too high, the cutting fluid is likely to cause allergies to the skin of the operator. If the concentration is too low, it will cause a lot of corrosion of bacteria.

Minimize the oil leaking from the machine tool into the cutting fluid, because the oil used by the machine tool contains bacteria.

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, it is difficult for bacteria to survive.

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

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

Thanks to cutting tools are Our’s main products, such as carbide CNC inserts, end mills, we learn the knowledge of cutting fluid from our customers.
