1.When using oil-based cutting fluid,why is there oil smoke or even fire?
This is a common problem in the use of oil-based cutting fluid,which is mainly caused by high temperature and high load during cutting.If the composition of the oil-based cutting fluid is relatively light and the flash point is low,it will produce lampblack and even catch fire.The solution is to use oil-based cutting fluid with heavy components and high flash point.If it is ineffective,water-based cutting fluid should be used.
2.Why do the hands of operators have skin allergy after using oily cutting fluid for a period of time?
There are many reasons for dermatitis and allergy,such as swelling or peeling of hands,or eye irritation,and the degree varies from person to person.Due to the long-term use of oil-based cutting fluid,some people's constitution is allergic to petrochemical products.If most people have dermatitis and allergy,it may be because the aromatic hydrocarbon content of the oil exceeds the standard,which has an impact on the cuticle of the skin;another possible reason is that the refining depth of the oil is not enough,and the oil is acidic or alkaline,which will erode the human skin.At this time,it is necessary to replace high-quality cutting oil in time.
3.Why does the oil cutting fluid use for a period of time,the workpiece rust phenomenon?
The corrosion resistance of oil-based cutting fluid is poor,which may be due to the reaction and decomposition of extreme pressure additives in the oil-based cutting fluid.For example,chlorine containing additives cause hydrolysis in the presence of trace water and cause rust;there are also rust caused by poor storage and storage of machined parts and poor environment.Specific solutions are as follows:
(1)Change the type of cutting oil and select the appropriate cutting fluid;
(2)Adding antirust agent can improve the antirust performance of oil cutting fluid;
(3)After processing,do a little anti rust treatment.
