Concrete road milling teeth, also known as drum teeth or cutting heads, are the components of a road milling machine that are responsible for removing the top layer of pavement. They are typically made from hard steel alloys to withstand the wear and tear associated with the process.
Each tooth is designed with a specific profile and size to suit different types of asphalt and concrete pavements. Here are some key aspects:
1. Material: The teeth are usually made from high-carbon steel or high-speed steel (HSS) for durability. Some advanced models might use tungsten carbide or other composite materials for increased longevity and cutting efficiency.
2. Profile: The shape of the tooth can vary widely. Common profiles include straight, helical, and spiral. Helical teeth are often used in asphalt milling due to their ability to provide a smoother cut. Straight teeth are more common in concrete milling.
3. Size: Teeth sizes can range from 2 inches to over 10 inc…
