Circular saw blade

Abstract

The invention relates to a circular saw blade. The circular saw blade comprises a round plate-shaped circular saw body and a plurality of knife teeth which are arranged at the periphery of the circular saw body. The circular saw blade is characterized in that the knife teeth comprise long knife teeth and short knife teeth; the length of the side centripetal lines of the long knife teeth is more than or equal to 4mm; the length of the side centripetal lines of the short knife teeth is less than or equal to 4mm; and the number of the long knife teeth takes up 2 to 15 percent of the total number of the knife teeth and is more than 2. According to the circular saw blade, due to the adoption of the long knife teeth, the size of the wave texture of the cross section of a machined material, which is caused by the vibration of a rotating shaft, can be reduced, and due to the adoption of the structure that the relatively cheap short knife teeth and the relatively costly long knife teeth are combined and the number of the long knife teeth takes up 2 to 15 percent of the total number of the knife teeth, the size of the wave texture of the cross section of the machined material can be reduced to the effect the same as or similar to the cutting state which is achieved when all the knife teeth adopt the long knife teeth. Due to the structure of the knife teeth, even the side surface of the circular saw blade is vibrated, the size of the wave texture of the cross section of the machined material can be greatly reduced and the circular saw blade is low in cost.

Description

technical field [0001] The present invention relates to a cutting tool for cutting wood, wooden boards, resins, ceramic series materials, metals, and composite materials composed of these materials, and a circular saw blade capable of processing grooves. Background technique [0002] As a cutting tool, a circular saw blade includes a circular saw body in the shape of a circular plate and a plurality of teeth arranged on the outer periphery of the circular saw body. The teeth are usually made of superhard alloy, or cemented carbide such as polycrystalline diamond, and are coated with a coating. Most of the cutter teeth are also provided with rake angles, inclination angles and grinding angles that are suitable for the processed materials. The circular saw blade is mounted on a machining device and performs material processing by rotary cutting. The occurrence of wavy lines on the cut surface of the processed material is caused by various reasons, such as the angle of the ce...

AI Technical Summary

Problems solved by technology

Especially in the processing devices used in some emerging countries, most of the vibration of the rotating shaft of the circular saw blade or the contact surface of the flange will appear once every revolution where the vibration is large, that is, at the side of the circular saw blade. A large vibration is generated, so the wave pattern on the cut surface of the processed material will be large
