THE RESULTS OF STUDIES OF THE MODES OF PINE GRINDING WOOD AND LIMITS ON THEIR USE
Currently in the wood processing roughness of industry high requirements to the quality of the products are applier, the machined surface after grinding on wood processing equipment, the final finishing before applying lacquer coatings. The basic requirements of the cutting theory, are receiving the products of established quality with the lowest cost at the necessary output. In this article were defined such points defined as the acceptable quality of wood surface of pine in the parameters of surface roughness (Rm<sub>max</sub> - the arithmetic mean of heights of individual the greatest irregularities on the surface, Rz - height of roughness profile on ten points if you count from the baseline, Ra - the arithmetic average of the absolute deviations of the profile) from various modes of processing (allowance for processing, feed speed, grit of the sandpaper). It was determined according variable modes, you cannot use the grinding-cutting tool, as on the sanding belt burn marks appeared as dark brown, black patches, which, in turn, can lead to transient deterioration of the grinding tool and in general dropin in producting.
