Metamob offers hardening services as a part of the complete maintenance of new and used blades or for the reconditioning of the blades that are currently in use. We perform hardening for narrow band saw blades used in woodworking, band saw blades for mobile saws, welded to the final dimensions.
Band saw blades for mobile saws with treated teeth are manufactured at Metamob S.R.L with a 58-61 HRC hardness value for the top of the teeth (hardened layer depth: 0,2-0,3 mm), while the core and the body of the teeth keep their initial structure remaining malleable. The fine structure of the cutting edge ensures smooth cuts and a higher durability.
In order to obtain this condition, the top of the tooth is heated up to its hardening temperature and then quickly cooled in air. The heat treatment is done with high frequency currents, by achieving in the conducting loop an equal and uniform heating of the top of the tooth. The rapid cooling occurs quickly in the surrounding environment and in the cool material of the body of the tooth. This is a simple operation that does not require a large amount of labour.
