The general material of circular saw blade is mainly used for cutting off low hardness carbon steel and non-ferrous metal rods and pipes. The cutting circular saw blade of super hard material is used for milling difficult cutting material (hot iron, stainless steel high hardness steel).

The angle parameters of sawtooth angle are more complex and the most professional, and the correct selection of sawblade angle parameters is the key to determine the sawtooth quality. The most important angle parameters are front angle, rear angle and cuneiform angle. The front corner mainly affects the force consumed by sawing sawdust. The larger the front corner, the better the sawtooth cutting sharpness, the lighter the sawing, the more labor-saving the push. Generally speaking, when the material is soft, choose the larger front corner, on the contrary, choose the smaller front corner. The angle of the sawtooth is the position of the sawtooth at the time of cutting. The angle of the sawtooth affects the performance of cutting. The front angle y, rear angle an and cuneiform angle β have the greatest influence on cutting. The front angle y is the sawtooth cutting angle, the bigger the front angle is, the lighter the cutting is, and the front angle is between 10 and 15 °C. The rear angle is the angle between the sawtooth and the machined surface, its function is to prevent the sawtooth from rubbing with the machined surface, the larger the rear angle is, the smaller the friction is, and the more smooth the processed product is. The rear angle of cemented carbide saw blade is generally 15 °C. The wedges are derived from the front and back corners. However, the cuneiform angle can not be too small, it plays a role in maintaining the strength, heat dissipation and durability of the teeth. The sum of the front corner y, the rear angle an and the cuneiform angle β is equal to the state of 9 countries.
The aperture selection aperture is a relatively simple parameter, mainly according to the requirements of the equipment, but in order to maintain the stability of the saw blade, it is best to choose the equipment with a large aperture for the saw blade above 250MM. The diameter of the standard parts designed in China is 20MM hole, most of the diameters of 120MM and below are 20MM hole, most of them are 25.4MM hole, most of them are 30 aperture, some imported equipment also have 1 5.875MM hole, the mechanical aperture of multi-slice saw is relatively complex, and most of them are equipped with keyways to ensure the stability. Regardless of the size of the aperture, it can be modified by lathe or wire cutting machine. The lathe can be sheathed in a large aperture, and the wire cutting machine can expand the hole to meet the requirements of the equipment. A series of parameters, such as the type of alloy cutter head, matrix material, diameter, tooth number, thickness, tooth shape, angle, aperture and so on, are combined into the whole of hard alloy saw blade. It is necessary to select and match reasonably in order to give full play to its advantages.
