Abstract (en)
[origin: WO2017001583A1] The invention relates to a method for manufacturing blanks having internal channels, comprising introducing a surface channel structure into a plate pairing, joining the plates to form a closed channel structure, threading a cutting wire into the channel structure, and further processing by means of wire-cut EDM in order to produce the final channel inner wall. The invention further relates to components produced by means of said method, and to corresponding applications.
