Yanggu Ruilister Engineering Machinery Co., Ltd. was established in 2014, the company is located in the east first of 23rd floor, Aolin Trade City, Yanggu County, Liaocheng City, Shandong Province. Mainly engaged in the production and sales of all kinds of cemented carbide products, such as basic rotary drilling tools, road milling tools, mining shearer tools, rotary digging sleeve, all kinds of joints, drilling tools and so on.
Milling teeth also known as milling machine cutter head or planing teeth, from the specification is basically divided into φ 20mm and φ 22mm two, which is in accordance with the size of the bottom diameter of the cutter head to distinguish; Milling machine is in accordance with the two size configuration of the cutter head, this is to facilitate the user to replace the cutter head; But the shape structure is much more complex, in the material: the cutter tooth part generally uses tungsten alloy material (equivalent to the international standard YG11C), hardness between 88-89hRa, flexural strength 2400N /mm2, density between 14.5-14.9cm3; The tool body is generally made of 42Crmo wear-resisting material, which is processed by cold and hot pressing die forging process. The hardness of heat treatment is between 42-44HRC. The hardness should not be too high, too high hardness will easily cause the fracture of the handle. The washer is made of hard elastic 65MO material with a diameter of 44mm, which avoids the direct wear of the tool holder during the milling of the tool head and effectively protects the service life of the tool holder.
