Research Projects

Development of a new resin-bonded, textured CBN and synthetic diamond grinding wheel for dry grinding of carbide metals and high-speed steel

  • Funding organization: National Ministry of Business and Energy (BMWi), 01/2013 - 12/2014
    Funding programme: ZIM joint project
  • Partner: Bärhausen

The main aim of the project is to develop a highly efficient and reliable finishing process which makes it possible to custom-grind hard materials, in this case hard metals and high-speed steel, using textured grinding wheels...read more

Innovative implementation of picosecond-lasers to dress and texture CBN and diamond grinding tools

  • Funding organization: Baden-Württemberg Ministry of Science, Research and the Arts
  • Funding programme: Innovative Projects / Joint project in BW universities
  • Partner: Bärhausen, Trumpf

High temperatures are the outcome of grinding processes. Solid cooling lubricants are used to reduce or dissipate the unwanted heat in the contact zone and small amounts of these end up in the grinding zone. The creation of special structures on grinding wheels is an effective way to...read more

Development of a new generation of machines to dress diamond grinding wheels using lasers - Laserdress

  • Funding organization: Federal ministry for Economic Affairs and Energy (BMWi) (2014-2016)
    Funding programme: ZIM Joint research project
  • Partner: Kirner Maschinenbau

Grinding machines with diamond granules are often used for the finishing of brittle and hard materials (carbide metal, ceramics, glass). The tool life is economical thanks to the extreme hardness of diamond granules. However this advantage is also a large disadvantage: contouring and dressing is very time-consuming. The silicium-carbide dressing rolls which are used are liable to considerable wear and tear. Therefore this process will be replaced with a completely new process using a non-wearing laser which until now has not been available on the market...read on
