Hollow ground hot cut friction saw blade for cut hot rolled steel profile
Description:
Raw material with high quality tool steel, imported and local steel enterprise, 45Mn2V, 50Mn2V, 65Mn, 51Mn7, 46Mn as saw body material, It is characterized by good comprehensive mechanical property, high hardness and abrasive resistance at the tip of tooth. Tooth hardness 50-55HRC,
It is used for cutting hot rolled steel sections, H beam,steel pipe and tube, and steel bar (square, round and flat). The temperature for cutting should be over 750℃, and 800℃ for high alloy steel. It requests the sawing machine with collent water above 3Mpa.
Saw blade material: 65Mn,45Mn2V, 50Mn2V, 46Mn, 51Mn7
Tooth forms/tooth geometry:
30/30 degree pendulum tooth
slaughter tooth
Finish of side face:
Flat ground finish,parallel ground
Hollow ground: side face are hollow ground, for maximum cutting clearance, reduce burr forming and high cut quality.
Cutting performance:
less cracking due to good ductility material
visible better cut quality
longer service life
Processing operation:
Laser cutting for volume production and improving saw blade quality, compare with shear and punching method which is easily lead to micro cracks, laser cutting machine minumizes this occurrence.
Heat treatment
Continuous quench system to increase hardness to request standard
Milling teeth with consistent precision, optimized to virtually no cracking
Tension testing/rolling/straightening machine
Each piece of steel core and saw blade being testing/rolling and straightening before delivery by our homemade high precision testing/rolling and straightening machine which arrurate to 0.01mm, proprietary rolling and straightening process results in highest precision and smallest side run-out.
