Parallel® AutoFlame 2500

Tooth Tip Hardening Machine for Hot and Friction (Cold) Saw Blades


  • For tooth tip heat treatment of saw blade diameters 1200-2500 mm, thickness – 16mm with flame hardening
  • Extremely robust structure for long lasting, trouble free operation with minimum maintenance requirements because of a sturdy machine frame made as a welded assembly, closed loop water cooling for the burner, splash protection sheets made of stainless steel and generously sized gear motor
  • Easiest adjustment and operation with no particular skill required
  • Unique burner design warrants reliable warning of the tooth tip to the spot with excellent visibility to the conversion process
  • Quick machining of the saw blade given by high cycle and advance speeds
  • Highly flexible thanks to adjustability of the burner/quench unit in 2 axes and inverter controlled adjustability of the saw blade rotational speed
  • Reliably prevents surface hardening of the tooth gullets and ensures reproducibly high hardening results (substantially superior to the induction hardening process)
  • 2 quench systems alternatively selectable so that blades made from all common materials can be processed


  • Saw blade size 1200 x 8 mm – 2500 x 16 mm
