Abstract
„Dynamic burnishing of wood” The subject of the article is dynamic burnishing of Wood, which is used in a different way than previously because it is used to surface structuring. Described technology is a method using burnishing of wood outer layer via multiplied impact by elements hanged on head which rotations result in their movement with simultaneous transmitting kinetic energy. Kinetic energy is changed into energy of plastic deformation of outer layer which is structured. A head with hammers and head driving device were used in the experiment. Keywords:
