IMPROVED TOOL AND METHOD OF MAKING

摘要

An improved saw blade is disclosed that includes a high precision finish on the blade for providing a low friction surface. Preferably the surface finish is less than approximately 10 Ra. The low friction surface allows for a thinner cutting tip relative to the blade. A method for forming a saw blade having a high precision surface finish. The method involves providing a high speed centrifugal finishing apparatus having an outer vessel and at least one inner vessel. A plurality of saw blades are mounted into the inner vessel, each saw blade being spaced apart from an adjacent saw blade. An abrasive finishing media is added into the inner vessel. The inner vessel is then rotated at high speed relative to the outer vessel. The high speed rotation causes the abrasive media to surface finish the blades. The finished saw blades are then removed from the inner vessel.
