Einfluß der Planlaufabweichung von Kreissägeblattschneiden auf den Zerspanvorgang

Cutting experiments with melamine-coated particleboards show to what extent axial run-out of the edges of carbide tipped circular saw-blades affects tool wear, cutting forces and the roughness of the workpiece edge. For protruding edges the effect on wear was greater than for receding ones. The same was true for passive forces. Saw-blades with minor axial run-out of the edges gave better quality work pice edges (less roughness of the cut surface) and had consid-erably longer service periods than blades with greater axial run-out. A new sharpening method and a suitable device were developed for sharpening sawblade edges, independently of axial run-out of the blade body. By this method circular sawblades can be produced with extremely low axial run-out of the blade edges.
