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.
