Kühlschmierstoff

Kühlschmierstoff, often abbreviated as KSS, is a fluid used in metalworking processes such as cutting, grinding, and drilling. Its primary functions are to cool the workpiece and tool, lubricate the cutting zone, and remove chips and debris. Cooling is crucial to prevent overheating, which can lead to tool wear, material deformation, and decreased dimensional accuracy. Lubrication reduces friction between the tool and workpiece, enabling smoother cutting, improving surface finish, and extending tool life. The removal of chips prevents them from interfering with the cutting process and causing surface damage.

Kühlschmierstoffe can be broadly categorized into oil-based, water-miscible, and synthetic fluids. Oil-based KSS offer excellent lubrication properties but can be less effective at cooling and may pose fire hazards. Water-miscible fluids, such as emulsions and solutions, provide good cooling and lubrication and are generally safer. Synthetic KSS are chemically engineered for specific applications and can offer a wide range of properties, including high performance and biodegradability. The selection of a specific Kühlschmierstoff depends on factors like the material being machined, the cutting operation, required surface finish, and environmental considerations. Proper handling, maintenance, and disposal of KSS are essential for workplace safety and environmental protection.
