Description
The service life of a wood band saw steel blade can be considerably improved by covering the tooth tips with wear-resistant alloys, such as stellite. This is particularly true for hardwood, but in recent years it has also proved successful for machining softwood such as fir and spruce. Stellite-covered tooth tips achieve better surface qualities and much longer durability. The subsequent careful sanding work on wet sanding machines with the appropriate sanding discs is of particular importance. To make full use of all the advantages of stellite facing, the steel material for the band saw must be of the highest quality; only then can a longer uninterrupted sawing process be achieved.
The operational time of a wood bandsaw blade can be increased considerably by tipping the teeth with wear-resistant alloys such as stellite. This is especially evident in sawing hard woods, but is today also used in the processing of softer woods like fir and pine.
The stellite-tipped teeth give better surface finishes and considerably longer operational times. It is vital, however, that the grinding work is carried out correctly, preferably by using wet-grinding machines and suitable grinding wheels. To utilise the properties of stellite in full, the basic steel material for the bandsaw must be of the highest quality to achieve a longer uninterrupted sawing operation.
