Segmental and Friction saw blades - Friction saw blades for metal cutting

Friction saw blades for metal cutting

 
Materials: steel tubes and profiles
Application: cutting by low working temperature, up to 250 C
Machine: machines for friction cutting

Characteristic:

» the cutting principal consists in melting of material in the cut place (due to friction caused by special kind of tooth)
» made from chrom-vanadium steel DIN 1.2235 (on request can be manufactured from material DIN 1.2604)
» they are heat-treated to reach the optimum ratio of tenacity and hardness, which makes them suitable for cutting materials with high circumferential cutting speed
» with straight or taper hollow ground; choice of flange diameter, number of teeth, central bore diameter, thickness, driving holes number and diameter is possible
» standard dimensions up to diameter 1000 mm , other dimensions can be manufactured on request, the maximal 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.

C.V.A. QUALITY

Recommended for casual and intermittent cutting.
Recommended for blades over 700mm diameter.
