Friction saw blades for metal cutting
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 chrom-vanadium steel marked (DIN 1.2235) 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. GSP - High Tech Saws, s.r.o. can manufacture these tools with taper of hollow ground. Choice of flange diameter, number of teeth, central bore diameter, thickness, driving holes number and diameter is possible. In the following table there is the survey of standard dimensions up to diameter 1000 mm. Other dimensions can be manufactured on request, the maximum diameter is 2500 mm.

Friction Saws

Made of high quality special steels, hardened in accordance with latest technical findings. They have milled special teeth and are hollow ground on both sides in modern precision grinding machines. All Wolferal blades are piece-by-piece examined for hardness, side run-out and concentricity. They can be mounted on all high-speed machines at recommended peripheral cutting speeds of 80-125 m/s. The ideal speed for cutting iron and steel is 125 m/s. For aluminium and other non-ferrous metals, special designs are available.
