Silicon nitride cutting tool
The additive manufacturing of cutting materials enables the development of more efficient cutting tools. Ceramics are an excellent alternative to carbide cutting materials, especially for high-speed turning. In their application, the insert is inserted into a clamping turning holder and fixed in place by holding down with a finger and tightening the screw.
Compared to conventionally manufactured parts for this application, the component optimized for LCM printing achieved a significant material saving thanks to a reduced wall thickness of < 4.4mm, offering a significant savings potential in series production.
The project was developed within the framework of AddiZwerk (Additive Manufacturing of Cutting Tools), financed by M-ERA.NET and FFG. Design by PTW (Institute for Production Management, Technology and Machine Tools) at TU Darmstadt.
