TREJO, Jhonattan; NININ, Pablo  y  ROSSSO, Franz. Management of the products quality in timber sawing as an effect on the blade quality in bandsaws. uct [online]. 2011, vol.15, n.61, pp.232-241. ISSN 1316-4821.

It was studied the effect that offers a finish on the sharpening of bandsaws on the primary processing of woods for the Energetic Group II. Two types of cutting tools with identical geometrical parameters were prepared, assigning as variable for this study a Tool A that represents the sharpening conventionally applied in the national sawmills industry by using only an abrasive stone with grain 60 (grinding stone), versus a Tool B that represents a finish in the sharpening of the bandsaws reducing significantly the roughness of the metal and decreasing the amount of burrs on the teeth edges of the tool by apply a final treatment with an abrasive stone with grain 120 (finish stone). The Tool B had a superior behavior than Tool A, because the number of defective products obtained with the Tool A were halved. The products which comply the dimensional tolerances established by the COVENIN (national standard) and the SPIB (american standard) were doubled. It demonstrated a Highly Significant Difference between both tools.
