Hollow ground hot cutting alloy steel circular saw blade balanced
Hollow ground hot cutting circular saw blade made by raw material with high quality tool steel, imported and local steel enterprise, 45Mn2V, 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: one side face are hollow ground and both sides 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

Quality control
During the production process, the saw blade will be subject to tolerance testing such as diameter and thickness, hardness testing, tension testing, and dynamic balance testing for large size saw blades. After a period of use, the saw blade needs to be grinded, and the tooth profile of the tooth part needs to be grinded and hardening. If the blade body is deformed, the flatness and dynamic balance of the blade body should also be done.
Equipment required for general repair includes
Automatic grinding machine
Flame or electrode hardening machine
Tension machine
Dynamic balancing machine
Quenching furnace
FAQ
What are the factors affecting the service life of the saw blade?
The service life of the saw blade is not only related to the material and tooth profile of the saw blade itself, but also to the set circumferential linear speed, feed speed, cooling water and other process parameters of the saw machine as well as the stability of the saw machine.
What is the minimum order quantity of the saw blade?
It is recommended that at least 5 test pieces for each specification be used. It can also be adjusted according to the production situation
What is difference between friction circular saw blade and hot cut circular saw blade?
The operate temperature is different. The operating temperature of the hot cut circular saw blade is higher than 750 ° C, and the friction circular saw blade is generally used at 200-300° C.
