A Cleaner Milling Process Replacing Emulsion Coolant by Cryogenics CO2

Abstract In manufacturing sector, looking for a balance between environmental and technical efficiency taking into account productivity is mandatory. Some sectors, such as the biomedical also needs to consider cleanness inherent prosthesis processes avoiding pathogens transfer human body, that is, neither chemicals, bacteria, nor uncontrolled metals can be introduced during surgical intervention. This work here presented stems from idea of analyzing cryogenic cooling applied medical pieces. For this, several samples were machined using CO2 technology oil emulsions, respectively. particular, modified milling tool was used apply not only efficiently cutting fluid but cleaner fluid. Afterwards, they analyzed by Scanning Electron Microscope (SEM) with aim biological remains. Finally, validating in which axially internal coolant, its life tested comparison conventional one. The results shown use coolant significantly improves current machining emulsions way injected does affect performance.
