I have not found any direct information on the lubricating effect of phenyl vinyl rubber in metalworking. However, I can provide some basic knowledge about phenyl vinyl rubber and similar materials, and the lubricating effect of metalworking.

Phenyl vinyl rubber, such as 120 methyl phenyl vinyl rubber (MBE), is a synthetic material with special properties and a wide range of applications. It generally has excellent wear resistance, acid and alkali resistance, high temperature resistance, and good tensile strength and elastic modulus. These properties make it widely used in many industrial fields, including automobile manufacturing, electronics industry, construction industry, etc. However, as for its specific lubricating effect in metalworking, more specific research or data may be needed to support it.

In metalworking, lubrication is usually achieved by forming an adsorbent film on the metal surface. This film can reduce the friction coefficient, thereby reducing cutting forces and cutting heat, reducing tool wear, and improving the quality of the machined surface. Common lubricants or lubricating fluids may contain ingredients such as vegetable oils, animal oils, fatty acids, mineral oils, and additives containing specific chemical elements. These components can physically or chemically react with the metal surface to form an effective lubricating film.

Although phenyl vinyl rubber may have certain lubrication-related properties (such as wear resistance, high temperature resistance, etc.), whether it is used directly as a lubricant in metal processing and its specific lubrication effect may need to be studied and tested according to actual conditions.

Therefore, for the lubricating effect of phenyl vinyl rubber in metal processing, it is recommended to conduct more in-depth research or consult experts in related fields to obtain more accurate information. At the same time, it is also necessary to note that the requirements for lubricants in different metal processing scenarios may be different, so in actual applications, it is necessary to select appropriate lubricants to meet specific needs.
