Hot and Friction Saw Blades approximately 2500 mm width are tools of high competence manufactured from well verified steel plates with a ductile forte of 850 bis 950 N/mm2. Friction saw blades are utilized for cutting of steel tubes and outlines by low employed temperature, it means by substance temperature up to 250° C. These are manufactured from chrome-vanadium steel patent (DIN 1.2235) and they are heat-treated to approach the finest ratio of stubbornness and rigidity, that is appropriate for cutting of substance with great circumferential cutting haste. The cutting principal contains in melting of substance in cut place began by superior kind of teeth.
Fields of application:
Substance is held to a rapid stirring welded to length saw blade classically running amid 6,000-18,000 f.p.m. The high frictional heat formed permits the band saw blade to scorch or melt away the substance while the bandsaw blade teeth eliminate the molten metallic from the working piece.
Meanwhile any agreed portion of the band saw blade is out of interaction with the metal cuts 99% of the while, the bandsaw blade itself relics cool to the bit. It is significant to note that resistance band sawing has resolved many problematic metals cutting glitches, but it has different limits imposed by the dimensions and widths of the work pieces. Widths over 3/4″ are enormously hard to friction cut. Very reedy or odd formed metals may be effectively cut by friction sawing when conservative approaches fail. Friction sawing makes very slight drag, so the uneven shapes can be detained win the pointers of the band saw operator and curved easily for trimming. The most archetypal supplies cut in is employing the friction sawing technique are:
