5 Typical Road Milling Teeth Wear & Tear

5 Typical Road Milling Teeth Wear & Tear


The service life of cutting tools fluctuates depending on different designs of milling teeth. The longevity can also be affected by the road conditions and even the operating style of the driver. Most of you, as experienced users, are familiar with these situations. However, in this article, I will cover five common types of road milling teeth wear and tear: 
 

 


Great Condition (hat-shaped):

The cutting tool wears fine, the tungsten steel tip is almost completely gone—no partial wear.

 

 
Normal wear and tear (cylindrical shape):

 

The cutting tool wears fine, the rotating performance is good,
but the tip becomes shorter. When this happens , the cutting tool needs to be replaced.


Abnormal wear and tear (carbide tip partial wear):

The cutting tool wears fine, the plate slightly wears out, and the tip wears out partially. This cutting tool rotates well though.

 


Tip fracture:

The tip fracture is due to the milling teeth getting crushed on the steel bars or large stones under the ground. The milling team has to detect the road condition in advance. 


Steel body partial wear: 

Compared to the tip, the steel body and washer are worn out badly. Possible Cause: The milling machine advances too fast but the conveyor system ejects the waste material too slowly. In this case, if the milling drum keeps turning, the cutting tools will be damaged eventually.


 

6 Tips for Getting the Most out of Road Milling Teeth 

Tip 1: Avoid hard objects

The road contains hard objects such as steel bars, rocks, and gutter covers. If milling teeth encounter these objects, a tip fracture is more likely to happen.

Tip 2: Sufficient water spray during the milling process:

The milling process will generate massive heat for the milling teeth. When the milling teeth overheat, It will cause higher milling teeth consumption. To avoid too much heat, the water spray system should regularly check the drain and increase the cooling water.

Tip 3: Slowing the cold planer advance speed:

The higher advance speed will increase the consumption of milling teeth and decrease road surface performance (the wider length).

Tip 4: Optimal Milling drum speed:

With a  higher milling drum revolution, you need a slower or optimal machine advance speed to ensure that every milling tooth gets a uniform load. When it comes to an emergency project, forcing you to speed up both milling revolution and advanced speed. You may be facing abnormal wear and tear of the milling teeth. 

Tip 5: Check the milling teeth regularly: 

The cutting tool has been completely worn out and its service life has been exceeded. Milling teeth should be replaced immediately to maintain the milling performance.

  

Tip 6: Avoiding abnormal wear and tear:

Sediment deposition will make milling teeth stop rotating during the process, increasing the possibility of abnormal wear and tear. Except that  the unique design of the milling teeth can minimize the possibility of abnormal wear and tear. The efficient cooling water spray for the spring plate can avoid sediment deposition, increasing rotation performance. The team should check the water spray system regularly. Once the cutting tool has been removed, the crew should check whether the tool holder is clean without any dust or any partial wear on the tool holder.
