Metalworking fluids (MWF) play a significant role in manufacturing processes, such as machining or forming. Consequently, a high number of MWF with varying chemical composition are commercially available. However, the working mechanisms of the MWF are still object of discussion in science and application. This paper addresses the possible interactions of additives with metal surfaces taking the...

Metalworking fluids (MWF) are responsible for hypersensitivity pneumonitis (HP). The aim of the present study was to identify the antigen (Ag) responsible for MWF-associated HP, and to optimise serological diagnosis by definition of a threshold allowing discrimination between HP patients and asymptomatic exposed workers. 13 patients, who were workers at a car engine manufacturing plant, were su...

A biotechnological method for metalworking fluids (MWF) wastewater treatment was developed. The research, conducted in a lab-scale bioreactor, proved that the process of eliminating pollutants from MWF wastewater proceeds effectively when the following are applied: multiple reinoculating of biomass by adding active microorganisms into the bioreactor, immobilizing microorganisms on the PVC foam ...

This paper presents a new method to lubricate, cool, and evacuate chips in metalworking operations using supercritical carbon dioxide (scCO2). Water-based and straight oil metalworking fluids (MWFs) are currently being used to perform these functions even though they are characterized by high economic, occupational health, and environmental costs. Carbon dioxide above its critical temperature a...

Metalworking fluids have the ability to extend cutting tool life and improve machinability of materials. There is a need for development reliable machining tests which can be used screen with high confidence allow ranking in terms performance. This study developed novel methodology utilizing single-point milling evaluate fluid performance wear forces across various aerospace alloys. The repeata...
