Abstract [eng] For the research the samples of ash (Fraxinus excelsior L.), birch (Betula L.), black alder (Alnus glutinosa L.), Scots pine (Pinus sylvestris L.) and spruce (Picea abies L.) wood were used with dimensions of (270×215×15) mm. All wood samples were tangentially planed, defect free and kiln dried. Before the research, the average moisture content, wood density, number of annual rings per 1 cm, average width of annual ring and wood surface grain direction were evaluated. Different wood surface roughness of the samples was obtained sanding wood samples in the eccentric sanding stand, using standard open-type sandpaper with different grit size. The arithmetic mean value of the single roughness depths of consecutive sampling lengths parameter Rz of the sanded wood samples were measured in five sectors along the wood grain, across and in the angle of 45°, using a contact stylus profilometer. In total 1800 measurements were done during testing series. In the research the dependence of wood surface on wood species, grain direction and grit size of abrasive material was evaluated. It was obtained that with increasing of the grit size of abrasive material, the roughness of wood surface decreases in all three measurement directions, but a linear dependence has not been established due to features of wood microstructure. In order to assess the quality of sanded wood surface accurately, it is recommended to measure the roughness of wood surface along and across the grain.
