Interaction between Additives in Metalworking Fluids under Difficult Cutting Conditions

In order to investigate the interaction between additives in metalworking fluids under difficult cutting conditions, tapping tests were conducted under different metalworking conditions for metalworking fluids consisting of liquid paraffin added with tricresyl phosphate (TCP), polysulfide (PS), and...
