Basic knowledge of tungsten carbide rotary burrs

Tungsten carbide rotary burrs are mainly composed of hard phase tungsten carbide and bonded phase cobalt, which is also known as tungsten carbide burr bits, mold milling cutters, etc. It is mainly used with a high-speed electric grinder and wind tools. Since its machining hardness can reach above HRA85, it is thus well suited to most materials, such as common cast iron, cast steel, copper, aluminum, marble, alloy steel, carbon steel, and other metal or non-metal materials. The working principle is that the tungsten carbide rotary burrs are clamped on a high-speed rotating tool and the cutting effect is achieved by the pressure and feed rate to which it is subjected. Tungsten carbide burr bits have excellent cutting performance and long life has a wide range of applications, such as for the finishing of metal mold cavities; For castings, forgings, weldments of the existence of the flying edge, burr, weld cleaning; Chamfering of a variety of mechanical parts, grooves, and keyway processing; Pipes, runners, parts of the inner hole surface cleaning and grinding; A variety of metal or non-metallic materials, such as engraving.

Classification of tungsten carbide rotary burrs

According to their head shape tungsten carbide rotary burrs can be divided into cylindrical (A), cylindrical head shape (C), round head arch shape (F), round ball shape (D), round head torch shape (H), 90° conical shape (K), 60° conical shape (J), 38° conical shape (M), arc disc shape (T), inverted cone (N), conical round head (L), conical tip (M), waist drum shape (B), oval shape (E), The tapered head (L), tapered tip (M), waist drum (B), oval (E), a curved arrow (G), conical flat head (S), cylindrical arc half-head (W), etc. The commonly used tungsten carbide rotary burrs grades are YG6, YG8, and YG10X.

How to improve the performance of tungsten carbide rotary burrs

To further improve the cutting performance and extend the service life of our tungsten carbide rotary burrs, we analyze them from their cutting and forming principles. Generally speaking, the tooth back of a tungsten carbide rotary burrs is composed of a straight line or curve: a straight line tooth back is easy to process, but the strength of its teeth is weak; The strength and processing difficulty of folded line tooth back is increased; The production difficulty of the curved tooth back is higher, but it can ensure the strength is basically equal in any cross-section point. Therefore, we need to study a tooth back that can be easily produced based on ensuring the strength of the tooth. Secondly, when the hardness and strength of the teeth meet the requirements, it is also necessary to pay attention to the tooth spacing. The size of the tooth spacing also plays a very critical role, its spacing is too large, the corresponding cutting performance and processing efficiency are reduced; If its spacing is too small, it can not ensure rapid chip removal, resulting in blockage of the cutter teeth, affecting the processing effect of the rotary file. The whole milling process can be divided into three stages, namely the initial wear stage, normal wear stage, and sharp wear stage. In each different stage the reasonable selection of tooth angle (front angle, back angle, main deviation angle, vice deviation angle, and edge inclination angle), can reduce the cutting force and cutting heat brought about by the wear, in the same cutting conditions, give full play to the cutting performance, improve the overall efficiency and machining accuracy. In general, for the rotary file material and rotary file edge teeth to improve, the material should have high hardness, high strength, high wear resistance, and good impact resistance and can still ensure excellent cutting performance under high-temperature conditions, but also facilitate processing; And the tolerance accuracy of the edge teeth to be accurate enough, the surface roughness to meet the established requirements. In addition, the new carbide staggered teeth have the characteristics of a short chip, smooth and high finish, and easy to operate, which can effectively improve the machining efficiency and machining accuracy of tungsten carbide rotary burrs.

Advantages of tungsten carbide rotary burrs

Tungsten carbide rotary burrs are extremely versatile and are used in mold processing and manufacturing. Chamfering, rounding, and groove processing of mechanical parts, cleaning up the flying edges, burrs, and welds of the cast, forged, and welded parts; pipe, impeller runner finishing processing, metal and non-metallic materials (bone, jade, stone) arts and crafts carving.

Tungsten carbide rotary burrs is an indispensable advanced tool for pincers and mold makers, which is characterized by replacing small grinding wheels with handles and no dust pollution, with a service life equivalent to several hundred small grinding wheels with handles, and a processing efficiency increased by more than 5 times, grinding various metal and non-metal materials with hardness below HRC70, with a grinding surface roughness up to RAl.6, easy to grasp, simple to use, safe and reliable, greatly reducing the heavy It is easy to grasp, simple to use, safe and reliable, and greatly reduces the heavy manual labor and production costs.

In general, tungsten carbide rotary burrs are the company's main product. For consumers, tungsten carbide burr bits are effective. The company will be more committed to producing more and better tungsten carbide rotary burrs for consumers. if you are interested in the business of tungsten carbide rotary burrs, you can go to our website for consultation, our website is https://www.7jinxin.com/.
