Roughness on the surface of the treated wood surface details of the timber is always bumps of various shapes and heights, formed during the processing. On the resulting surface finish timber, the following irregularities of different origin: the risks of destruction bumps, bumps. elastic recovery, structural irregularities. Risks are the traces left on the treated surface of the working bodies of the cutting tools. The risks are shaped crests and grooves caused by geometrical shape of the teeth saws.
Irregularities elastic recovery are formed as a result of unequal size elastic buckling cutting tool surface layer of wood in areas of varying density. Different density and hardness of the annual rings of wood recovered after passage of the tool is not the same, resulting in which the surface treatment produces uneven. Structural irregularities are different in shape, size and location of the basin, obtained on the surfaces of products molded from wood particles, and due to the method of manufacture of these products and the arrangement of the particles. Hairiness – a presence on the surface treatment is often located partially separated fibers. In the shop floor to Comparative visual assessment of surface roughness polzuyuteya specially manufactured standards.
Each model is made from the same wood species and process issues. same kind of cutting, and controlled by that part. shop conditions for a comparative visual assessment of surface roughness polzuyuteya specially manufactured standards. Each model is made from the same wood species and process issues. same type of cut, and that controlled items.
