During the machining process, the lathe can operate at very high speeds. When it makes contact with the workpiece, heat is generated. To maintain the material’s temperature within the desired range, cooling or lubricating oil is used. These oils dissipate heat from the material to help regulate its temperature. However, during this process, the heated oil can evaporate or even burn, depending on the lathe’s speed and the type of oil used.
Oil Mist and Oil Smoke (Burnt Oil Smoke, Oil Smoke) refer to the vapor or fog released as a result of this evaporation or burning of various coolant and lubricating fluids used in machining process.
The release of oil mist and oil smoke is not influenced by the use of either neat oil or emulsions. What truly matters is the size and concentration of the particles. As spindle speed and coolant pressure increase, the particles become smaller, and their quantity rises.
