Road planer teeth one of the primary accessories of the road milling machine. The milling machine is a kind of high-speed milling machine, which is called the milling cutter, the road milling tooth or the road tooth, the road tooth, the milling machine tool. Is the use of the head and the ground touching the road milling operations;
Pavement milling teeth from the standard is basically divided into Φ20mm and Φ22mm two, which is in accordance with the size of the bottom of the head to distinguish the size; imported or domestic milling machine is configured in accordance with these two standards of the head, which is In order to facilitate the user to replace the head; but the appearance of the layout of the more complex, each company's appearance are not the same, but only need to distinguish the two categories, the other is basically universal, A grid, as each company in the head of the planning at the beginning, to fully consider the milling machine head in the high-speed rotation milling operations, how to more effectively maintain the alloy on the head some thinking about how to reduce the appearance of talent The head resistance in the operation? How can the knife be more conducive to flexible rotation in the operation? So we do not need to think in the purchase of its appearance, each company's products have its unique side;
In the data: the tip of some commonly used tungsten alloy material (equivalent to the international symbol YG11C), hardness between 88-89HRA, bending strength 2400n / mm2, density 14.5-372.5px3 between the body is usually selected 42Crmo wear Information, the choice of hot-pressing die forging skills from processing, heat treatment hardness between 42-44HRC, the hardness should not be too high, but will be too high hardness of the formation of the knife handle cracking; gasket made of strong elasticity 65mo , A diameter of 44mm, to avoid the knife head milling operations on the knife seat of the direct wear and tear, and effectively maintain the life of knife seat;
