Friction Saw Blades
Metaltech offers an extensive range of finest quality of friction saw blades to our clients. Friction saw blades are used for cutting of steel tubes and profiles by low working temperature, it means by material temperature up to 250° C. They are made from chrome-vanadium steel and they are heat-treated to reach the optimum ratio of tenacity and hardness, which is suitable for cutting of material with high circumferential cutting speed. The cutting principal consists in melting of material in cut place caused by special kind of teeth. The tooth geometry and tooth pitch are determined by the section and quality (analysis) of the material to be cut and the sawing machine. The shape of the teeth is such as to support clearing of debris from the tooth gullet.
NMPL offers its client the Choice of flange diameter, number of teeth, central bore diameter, thickness, driving holes number and diameter as the cutting characteristics are also influenced by the tooth-shape and pitch. The number of teeth required to be active determines the pitch and hence the number of teeth for a given diameter, i.e. in contact with the material being cut, at any one time. In cut for small and medium section, 4 to 8 teeth must be engaged and for large sections 8 to 12 teeth in contact is required.
Other customer specified special friction saw blades are available to order.
