ROAD MILLING PICKS

The milling teeth are divided into asphalt pavement milling teeth and cement pavement milling teeth. It is a cutting tool for pavement, which is directly assembled on the milling drum of the milling machine or regenerative machine. The spring and the card are composed of four parts. The specifications of the Liliqing pavement milling teeth are divided into two types: tool holder diameter 20mm and tool holder diameter 22mm. The tool holder is 20mm and is commonly used in road milling machines. The tool holder 22mm is generally Used for regenerative milling machine! Whether it is an imported milling machine or a domestic milling machine, the cutter head is basically configured according to these two sizes, this is to facilitate the user to replace the cutter head;

 

Although the structure of the milling tooth is very simple, the shape is very complicated. The shape of each company is not the same, but the basic design idea is the same. That is to ensure that the cutter head of the milling machine ensures that The cutter body and cutter teeth of the cutter head are in a state of simultaneous wear and tear, and the resistance of the cutter head in the work is reduced as much as possible, and the ground is cut quickly;

 

The material of pavement milling teeth generally adopts YG8C tungsten-cobalt alloy material as the tooth material, the hardness is between 88-89HRC, the bending strength is 2400N/mm², the density is between 14.5-14.9cm³, the wear resistance is strong, and it has good resistance Impact performance;

 

The cutter body of the asphalt pavement milling teeth is made of 42Crmo wear-resistant material, which is processed by a cold extrusion molding machine. The heat treatment hardness is between 44-46HRC, and the bending strength is high, ensuring that the cutter teeth and the cutter body are in a state of simultaneous wear;

 

The shank part of the pavement milling gear is machined by the machining center, and the effective gap between the circlip and the shank is strictly controlled to ensure that the cutter head can not only flexibly rotate after being inserted into the tool holder, but also never fall off;

 

The card with milled teeth is to lock the circlip and facilitate the assembly of the cutter head. The diameter is generally 44mm. It is made of high-strength wear-resistant material and can effectively protect the tool holder and delay the normal wear of the tool holder;

 

The retaining spring of the asphalt pavement milling teeth is made of hard elastic 65Cmo material with high elasticity and large expansion force, which can lock the cutter head for a long time and ensure that the cutter head does not fall off due to the strong impact force;
