Oil based cutting fluid: oil based cutting fluid, also known as cutting oil, its basic composition is base oil (mineral oil or synthetic oil). When using, it doesn’t need to be diluted, and the stock solution is used directly.

Another harm of metal cutting fluid oil mist is its carcinogenicity. The carcinogenicity of metal cutting fluid mainly depends on the concentration of additives, pollution and service conditions. At present, there is no research on the carcinogenicity of metal cutting fluid for human, but the experimental research on animals shows that the oil mist of cutting fluid can cause skin tumor \/ skin cancer, stab tumor, lung cancer and pancreatic cancer. There are still many controversies about the carcinogenicity of cutting fluid oil mist: Although many epidemiological studies have reported the carcinogenic tendency of metal cutting fluid and its oil mist, due to the long incubation period of cancer, epidemiological studies can only evaluate the harm caused by a certain substance 20-30 years ago. For this reason, some researchers point out that the composition of metal cutting fluid decades ago can not represent the situation of today’s cutting fluid. In particular, great changes have taken place in the refining process, and PAHs and other undesirable components have been removed to a greater extent. Therefore, it is not appropriate to extend the previously proven carcinogenic tendency to the current cutting fluid. However, due to the complexity of the composition of metal cutting fluid, it is very difficult to simply prove that it is not carcinogenic.<\/strong><\/p>\n\n\n\n

Classification of cutting fluids Proportion by processing type and application: According to morphology, there are liquid cutting fluid and solid lubricant. There are two kinds of liquid cutting fluids commonly used in production: Oil-based cutting fluid (cutting oil) mainly used for lubrication and water-based cutting fluid (cutting fluid) mainly used for cooling.
