  • Grinding of Iron-aluminides 
    Köhler, Jens; Moral, Analía; Denkena, Berend (Amsterdam [u.a.] : Elsevier, 2013)
    Since the 1930s iron-aluminides are investigated due to their excellent corrosion resistance, low density and high specific strength. However, little work has been carried out on the machining of these alloys since then. ...
  • Grinding with patterned grinding wheels 
    Denkena, Berend; Grove, T.; Göttsching, Tim (London : Elsevier Ltd., 2015)
    Grinding is one of the most important manufacturing processes, especially when high surface qualities have to be realized or if hard or brittle materials have to be machined. Often the grinding performance is limited by ...
  • High performance peel grinding of steel shafts using coarse electroplated CBN grinding wheels 
    Denkena, B.; Krödel, A.; Wilckens, M. (Heidelberg : Springer, 2021)
    Grinding is widely known for its low material removal rates and high surface quality. However, recent developments in production processes for cubic boron nitride (CBN) abrasive grains have led to commercially available ...
