How does cutting oil play a lubricating role?
The main reason why cutting oil lubricates during machining is that it forms a lubricating film on the surface of the tool and the workpiece, separating the direct contact between the tool and the workpiece, thereby reducing friction and wear.
Specifically, additives in cutting oils form a lubricating film during metal cutting, which adheres to the surface of the tool and workpiece, reducing friction and preventing wear. At the same time, additives such as extreme pressure agents in cutting oils can form a thicker lubricating film under high load conditions, improve lubrication effect, and further reduce tool wear and surface damage.
In addition, the cutting oil also has a cooling effect, which can take away the heat generated during the machining process, reduce the temperature of the tool and the workpiece, thereby extending the life of the tool and improving the machining efficiency. At the same time, the cutting oil also has certain anti-rust properties, which can prevent metal products from rusting during processing.
In summary, cutting oil plays a lubricating role in the machining process by forming a lubricating film on the surface of the tool and workpiece, reducing friction and wear, taking away heat, and preventing metal rust.
