Alloy Rotary Bits Tungsten Carbide Rotary Burrs With World Leading Welding Grinding Tools

We analyze from its cutting and forming principles. Generally speaking, the back of a hard alloy rotary file is composedof a straight line or a curve: a straight back is easy to process, but the strength of its teeth is weak; the strength of the brokenline back and the difficulty of processing are increased; Is difficult to produce, but it can ensure that the strength at any cross-section point is basically equal. Therefore, we need to study a kind of tooth back that can be easily produced on the basis of ensuring the strength of the tooth. Secondly, when the hardness and strength of the teeth meet the requirements, it is necessary to pay attention to the tooth spacing.

The size of the tooth spacing also plays a very important role. If the spacing is too large, the corresponding cutting performance and processing efficiency will decrease; if the spacing is too small, it will not be possible to ensure rapid chip evacuation, resulting in blockage of the cutter teeth and affecting the rotation Processing effect. The whole milling process can be divided into three stages, namely the initial wear stage, normal wear stage and sharp wear stage.

Through the selection of reasonable cutter tooth angles (rake angle, rake angle, main declination angle, auxiliary declination angle and blade inclination angle) at each different stage, the wear caused by cutting force and cutting heat can be reduced. Under cutting conditions, give full play to cutting performance, improve the overall efficiency and processing accuracy. In general, the improvement from the rotary file material and rotary file blade teeth should have high hardness, high strength, high wear resistance, good impact resistance and still ensure excellent cutting performance under high temperature conditions. It can also be easily processed; the tolerance precision on the blade teeth must be accurate enough, and the surface roughness must meet the established requirements. In addition, the new carbide interlaced teeth have the characteristics of short chips, smooth and high smoothness, and easy operation, which can effectively improve the machining efficiency and machining accuracy of the carbide rotating file.
