Suitable for Asphalt Concrete Road Milling Teeth Round Shank Cutter Pick for Milling Manhole Covers

Product Description

The manhole cover milling teeth are specially used for the road manhole cover milling machine! The manhole cover milling teeth are similar to the traditional pavement milling teeth. It can also be said to be a recycled version of the pavement milling teeth, but the size has changed! 
The manhole cover milling teeth are generally composed of three parts: cutter teeth (tungsten cobalt alloy), cutter body (42CrMo) and elastic ring. -2mm) two kinds;
Because the pavement materials around the manhole cover are not all the same, some are asphalt mixed roads, but some are concrete mixed roads! Therefore, the manhole cover milling teeth must first be able to adapt to different pavement materials, not only must have the ability to cut quickly, but also have good impact resistance and bending resistance! The milling teeth of the manhole cover milling machine are often made of high-quality tungsten-cobalt alloy materials! You can also directly choose a special cutter head for milling asphalt materials, and you can also directly choose a special cutter head for milling concrete materials!

The cutter body is made of 42CrMo material, which is processed by cold extrusion and has high bending strength and strong wear performance!
The elastic ring of the manhole cover milling tooth is made of high-elasticity 65Mo material, which has high elasticity and large expansion force, and can withstand long-term expansion force;
Hardness is an important guarantee for product quality. Reasonable quenching can effectively improve the service life of the manhole cover milling teeth. The hardness of the cutter body of the manhole cover milling teeth is controlled at about 50HRC, and the hardness of the alloy teeth is maintained at about 89HRA.

Tooth (alloy) material:
It is made of coarse-grained JCK3 tungsten-cobalt alloy raw material (tungsten carbide powder), which is sintered under high pressure and vacuum. The bending strength reaches 2400N/mm2 and the density is between 14.5~14.9cm3.
 

 

Body (base) material:
It is made of high wear-resistant 42Crmo material, which is formed by secondary forging and then machined. The hardness is between 44~48HRC, with high bending strength and strong wear resistance!
The shape of the base body can be designed with different base body structures according to the actual use requirements!
 

Circlip: 65Mo elastic material with a thickness of 1.2mm is used, which has a large expansion force and can firmly lock the cutter head for a long time to ensure that the cutter head will not fall off!
Card material: 65Mo with a thickness of 4mm is used as the material, which can protect the direct wear of the knife seat for a long time!
