Carbide saw blade because of its high hardness, impact resistance, wear resistance, at high temperatures can still maintain the normal cutting capacity, etc., be widely used in wood processing industry. Appropriate use of carbide saw blade can reduce the number of grinding, improve the surface quality, to achieve the purpose of sawing plane, thereby increasing efficiency and yield.
Tungsten carbide with several grade,Cobalt content increased, the impact toughness and strength also increased, but the hardness and wear resistance will declined, we should choose tungsten carbide grade according to the actual situation.
How to choose tungsten carbide saw blade ?
To choose tungsten carbide saw blade , we should consider the cutting type of workpieces, thickness, sawing speed, cutting direction, feeding speed, saw road width and other specific detail. All these come back to the selection of tooth of saw blade, angle and other parameters.
Below is a geometry parameters introduction of carbide saw blade .
1.Tooth choice of saw blade
Tooth form of Circular saw blade is divided into left and right teeth, tapered teeth, flat teeth, trapezoidal teeth, crescent-shaped teeth, etc.,in application,type of workpieces is the mainly basis to choose tooth form of cemented carbide saw blade.
2.Angle choice of sawtooth
The angle parameter of the sawtooth part is complex, but the angle parameter of the saw blade is the key to determine the sawing quality. The most important angle parameters are the anterior horn, posterior horn, wedge angle. The rake angle primarily affects the force consumed by the sawdust. The larger the rake angle, the better the sharpness of the saw blade, and the lighter the sawing, the more effort the pusher. Generally ,when processed material is soft, the larger the front horn.
