The treatment strategy of machine rust during the use of cutting fluid
Cutting fluid plays a vital role in the metal processing process, which can effectively reduce friction and heat in the cutting process, improve the surface quality of the workpiece and tool life. However, the use of cutting fluid is not without risk, one of the common problems is machine rust. This paper will focus on the cause of machine rust during the use of cutting fluid and the corresponding treatment strategy.
One of the main causes of machine rust is the moisture in the cutting fluid. Water-based cutting fluid contains high moisture, and when these cutting fluids are in contact with the surface of the machine for a long time, water may penetrate the metal surface of the machine, resulting in rust. In addition, impurities in the cutting fluid, such as iron filings, sediments, etc., may also be attached to the surface of the machine, forming rust spots.
In view of the rust problem of the machine, the first thing we need to do is to regularly detect the concentration change of the cutting fluid, and add new cutting fluid in time according to the actual situation. Keeping the concentration of the cutting fluid stable can ensure the stable performance of the cutting fluid and reduce the risk of corrosion to the machine. At the same time, for the impurities in the cutting fluid, it is also necessary to regularly clean up to avoid causing damage to the machine.
In addition, controlling the pH value of the cutting fluid is also the key to prevent rust on the machine. The pH value of the cutting fluid is too high or too low may lead to rust. Therefore, we should keep the pH value of the cutting fluid in the appropriate range to avoid corrosion on the surface of the machine.
However, even if we take the above measures, sometimes the problem of machine rust may still occur. In this case, we need to take more proactive measures. For example, for the surface of the machine that has been rusted, we can use professional rust remover to treat it, remove the rust and restore the finish of the machine surface. At the same time, in order to prevent rust again, we can apply a layer of anti-rust agent on the surface of the machine to form a protective film to isolate the direct contact between the cutting fluid and the surface of the machine.
In addition to the processing of cutting fluid and machine, we also need to strengthen the management of cutting fluid. During the use of cutting fluid, its effective ingredients will gradually be consumed, and impurities or bacteria may also be mixed, leading to a decline in its performance, and even causing problems such as machine rust. Therefore, we should regularly test the cutting fluid to ensure its stable performance. At the same time, for the cutting fluid that has been deteriorated or polluted, it should be replaced in time to avoid damage to the machine.
It is worth noting that the anti-rust performance requirements of different materials are also different. For example, stainless steel has relatively low requirements for rust prevention, while rust-prone materials such as cast iron have more stringent requirements for the rust prevention performance of cutting fluid. Therefore, when choosing the cutting fluid, we need to make a reasonable choice according to the material of the machine to ensure that the cutting fluid can meet the anti-rust needs of the machine.
In summary, the treatment of machine rust during the use of cutting fluid needs to start from many aspects. We need to regularly detect the concentration and pH value of the cutting fluid, clean up the impurities in the cutting fluid, and keep the performance of the cutting fluid stable; At the same time, for the surface of the machine that has been rusted, we need to use professional rust remover and anti-rust agent for treatment; Finally, we also need to strengthen the management of the cutting fluid to ensure its stable performance and avoid damage to the machine. Through the implementation of these measures, we can effectively solve the problem of machine rust during the use of cutting fluid, and ensure the smooth progress of metal processing.
