Abstract
Cooling the tool cutting edge during the machining of titanium is indispensable for an economical and productive process. Innovative cooling processes using carbon dioxide (CO2) or liquid nitrogen (LN2) can further increase tool life, especially when machining materials with low thermal conductivity. When drilling with high length to diameter ratio tools, cooling of the cutting edge is only possible via an internal supply of the cryogenic medium. Previous system solutions relied on the method of passing the cooling medium through the tool spindle. This paper presents an innovative approach that enables the supply of liquid carbon dioxide as a cooling medium to a drilling tool without passing it through the tool spindle. The operating behaviour in idle speed at different spindle speeds is shown and, additionally, its suitability for drilling processes is presented by means of a chip analysis.
