Kühlschmierstoffsystemen

Kühlschmierstoffe, often abbreviated as KSS, are essential fluids used in machining operations. Their primary functions are to cool the cutting zone and to lubricate the interface between the cutting tool and the workpiece. This dual action significantly improves the efficiency and quality of the machining process.

Cooling is critical because the friction generated during cutting produces substantial heat. Excessive heat can lead to tool wear, workpiece distortion, and poor surface finish. KSS absorbs this heat and carries it away, preventing these detrimental effects. Lubrication, on the other hand, reduces friction, which in turn minimizes tool wear, lowers cutting forces, and helps to produce a smoother surface finish on the workpiece.

Kühlschmierstoffe can be broadly categorized into several types. Water-miscible coolants, also known as soluble oils or semi-synthetics, are dispersions of oil in water. Straight oils are mineral or synthetic oils that are not diluted with water. Synthetics are typically water-based fluids containing no oil, relying on chemical additives for lubrication and corrosion protection. Each type has its advantages and disadvantages depending on the specific machining application, material being cut, and desired performance characteristics.

Beyond cooling and lubrication, KSS also plays a role in flushing away chips and debris from the cutting zone, which prevents chip recutting and further improves surface finish. They also offer corrosion protection for both the workpiece and the machine tool components. Proper selection, maintenance, and disposal of KSS are crucial for both operational efficiency and environmental compliance.
