MORESCHI’S FRICTION SAW BLADES

Lame Moreschi Blade cut Acciaio tubi
LAME CIRCOLARI cermet taglio acciaio - MORE life

  • DESCRIPTION

The friction saw blades are used to cut billets, tubes, slabs and grates. They are called friction because the cut is done thanks to the friction between the teeth of the blade and the working material.

  • MATERIALS

Our saw blades are manufactured from hot rolled steel sheet in chromium-wanadium 1.2235 or wolfram-molybdenum 1.2604 choosing the hardness according to the temperature and the type of the material to be cut.
We can supply saw blades hardened all over, on the external belt or on the teeth tips. The flanks can be grinded: tapered with hub, straight or left black as hot rolled.

The “secret” for the optimization of the cut with friction saw blades is finding the right balance between the saw hardness and the combination hardness/temperature of the material to be cut.
Moreschi uses successfully specific tooth form accordingly with the type of material and the cutting conditions

  • BP e BN to cut low-carbon steel tubes and profiles at a temperature < 250° C

  • V e VP to cut thick low-carbon steel and stainless tubes and profiles at a temperature > 800° C

  • M to cut solid steel in cold and hot conditions.

  • RECOMMENDED CUTTING VALUES

Materiale / MaterialVc (m/min)Troncatura Profili e Pieni Vf (mm/min)
Profiles and solids cut-off
Acciaio al carbonio

It is important for the good operation of the friction and hot saw blades that the debris of the work materials are removed from the gullets of the teeth using high pressure jets of coolant at the exit of the cutting zone.

Please note that the recommended cutting parameters are only general indications and they must be adjusted depending on cutting conditions, sawing machine conditions and the material to be cut. Our technical department is available to help you finding the most suitable parameters for each particular application.
