FRICTION SAW

Large Friction Saws:
Used for friction cutting cold carbon and alloy steels, usually multiple pieces. Finer tooth pitches used to generate frictional heat during cutting. High pressure cooling and clearing of teeth and generous body cooling is vital to blade operation.

Blade Materials:
POWERBLADE Carbon, Manganese Steel, normalised body 22 HRC with flame hardened teeth 48 to 54 HRC. Tough crack resistant blade body combined with hard wear resistant teeth, to provide considerably increased blade life between sharpens compared to medium carbon manganese steel blades.

Size Range:
1000mm to 2400mm diameter (39 to 94 inches)
6mm to 16mm thick (0.236 to 0.63 inches)
Tooth Pitch 5mm to 28mm (0.2 to 11/8 inches)

Tooth Profiles:

  • Standard profile is 60°Peg used for both hot and friction cutting

  • Special tooth form for specific applications

  • 60°Peg with land – friction cutting steel tube

  • Handsaw tooth – solid bar and billets

  • XLR and Skip tooth – hot cutting jumbo beam

Blades are precisely machined, levelled and tensioned to ensure even balance, vibration free running and accurate cutting at speeds from 4267 to 7620 m/min (14000 to 25000 ft/min)

Small Diameter Friction Saws:
350mm to 1200mm diameter (14 to 47 inches)
Used for friction cutting of small steel tubes and sections.

Materials:

Chrome Vanadium Steel or Tungsten Molybdenum Steel usually over 600mm (24 inches). Hollow profiled for clearance. Standard peg or special tooth forms.
