GRINDING SOLUTIONS FOR BAND AND GANG SAWS
SHARPENING, MACHINING AND MAINTAINING BAND SAW BLADES CORRECTLY
Measuring, stellite tipping, straightening, tensioning, levelling, swaging and sharpening: These are the keys in the field of precision machining of band and gang saw!
Modular solutions from ISELI effectively realize these key factors with state-of-the-art machine and system control technology. With maximum productivity, they ensure that a saw shop is more profitable at manufacturers of tools, service providers as well as for sawmills With the world´s largest machine program for band and gang saws we set standards for precision, reliability and efficiency. Our modular machine solutions realize these key factors effectively and practically and ensure lasting product quality and cost advantage !
Band saws are highly sensitive. If maintained incorrectly, they may break. The reason for this is that band saws are subject to a constant bending cycle. This can cause hairline cracks to form in the tooth gullet, the area of highest tensile stress. If the saw is not resharpened on time, these cracks grow and cause breakages. To prevent this, the whole profile, i.e. all of the teeth (irrespective of their shape), of band saws made of CV steel and stellited band saws must be regularly resharpened – even when the usual degree of bluntness has not been reached in some places.

SWAGING AND SHAPING BANDSAWS
Swaging saw teeth is another possibility, along with setting, for ensuring that the bandsaw can cut freely during machining. For the swaging process, a swaging bolt is placed in front of the saw tooth. The saw tooth is held in place with an anvil.
By turning the eccentric swaging bolt, the sawing material is pushed towards the tooth tip. When the swaging process has ended, the swaging bolt turns back to its starting position.
Leveling takes place after swaging, i.e. the material which was pushed towards the tooth flanks is pressed together with the appropriate equalizing jaws, so that the tooth tip is conically tapered downwards and backwards. As the swaged saw tooth works on the entire kerf width, it carries out the same work which would be carried out by two teeth on a set saw. The cutting power is increased thanks to the greater number of main and minor cutting edges. In addition, the hardness grade of the base material is increased thanks to the swaging process.
