Functional and Environmental Evaluation of Alternative Disinfection Methods for Cutting Fluids

Cutting fluids are widely used to ensure high production quality and process stability in machining processes. However, especially in case of water based cutting fluids microbial contamination leads to a reduced performance and thus, shortened service life. To control the growth of microorganisms biocides are used in practice. Biocides, however, can be toxic to humans and the use is officially regulated, whereby alternative disinfection methods e.g. ultraviolet radiation or ozone are getting more in the focus. This paper describes and performs a functional and an environmental evaluation of alternative disinfection methods.
