Project EDIgDIS

Development of Diamond Cutting Tools with Arranged Diamond Structure via Three-Dimensional Screen Printing  

Project Consortium:

as part of the BMBF funding programme:  KMU innovative „Production Engineering“

Duration of the project:  01.05.2013 until 31.03.2016

The goal of the project "EDIgDIS" was to develop a new and subsequently patented production technology for innovative diamond cutting tools. A manufacturing concept for the production of corresponding tools with three-dimensionally arranged cutting particles using the three-dimensional screen printing process was developed. With these new cutting tools and their diamond cutting body arrangement, a scalable, adaptable and further optimisable structuring of cutting carriers could be developed for the envisaged applications. The main innovation is the defined positioning of the diamonds in the cutting body by means of a mass production process. An exact reproducibility of the cutting geometry and cutting properties of the tools could be guaranteed and a scalability to different tool geometries could be shown. Studies on the influence and selection of the raw materials, parameters and printing tools required for the 3D screen printing process as well as the application behaviour of the cutting tools from a test production complete the achieved project goal. In order to be able to demonstrate the industrial practical relevance, diamond saw wires were created from the prototypes as demonstration tools and tested in comparison to established diamond tools.
