Zerspanungsöle

Zerspanungsöle, also known as cutting oils, are specialized lubricants designed to enhance the performance of metalworking processes, particularly cutting and grinding operations. These oils are formulated to reduce friction, dissipate heat, and prevent the formation of built-up edges (BUE) on the cutting tool. This results in improved tool life, reduced wear, and better surface finish on the workpiece.

Cutting oils are typically composed of a base oil, which provides the lubrication, and additives that enhance performance. The base oil can be mineral, synthetic, or semi-synthetic, each offering different levels of thermal stability and viscosity. Additives may include extreme pressure (EP) agents, anti-wear agents, and antioxidants to protect the tool and workpiece from damage.

Zerspanungsöle are classified based on their intended use, such as for turning, milling, or grinding operations. They can be applied through various methods, including flood cooling, minimum quantity lubrication (MQL), or dry cutting, depending on the specific requirements of the machining process.

The selection of the appropriate cutting oil is crucial for achieving optimal results in metalworking. Factors to consider include the type of material being machined, the cutting tool material, the cutting speed and feed rate, and the desired surface finish. Regular maintenance and monitoring of the cutting oil's condition are also essential to ensure consistent performance and prevent contamination of the workpiece.
