Application Potential of Additively Manufactured Mounted Points with Internal Cooling for Machining Zerodur®

For machining Zerodur®, manufacturing processes with geometrically undefined cutting edges are primarily used. A supply of metalworking fluid to the cutting zone as required is decisive for a long tool life. Internal cooling channels in mounted points are usually manufactured by means of conventional subtractive processes or when sintering the base body, which is why the shaping and positioning of the channels are subject to manufacturing restrictions. The design freedom offered by additive manufacturing processes opens innovative approaches for optimizing the cooling channels. © 2022 Walter de Gruyter GmbH, Berlin/Boston, Germany.
