Introduction:
Milling teeth, also called milling machine cutters or road planing teeth, are the core cutting components of road milling machines. There are different sizes based on the diameter of the cutter head base and are compatible with mainstream milling machine models both domestically and internationally. Its structure consists of alloy milling cutter teeth, tooth body, clamping spring and retaining ring, which can be quickly replaced through modular design, and its core function focuses on reducing cutting resistance and improving rotational flexibility.
Milling teeth are widely used for excavation, renovation, and repair of asphalt concrete pavements on highways, urban roads, airports, and freight yards, removing bumps, uneven textures, rutting, and other road surface defects. Milling teeth can also be used to excavate potholes and trenches, as well as excavate and mill trenches on cement pavements.
Precise Asphalt Removal: Milling can be performed in layers (depth adjustment from 0-30cm) to remove rutting, cracking, and bumps.
Concrete Roughening: Creates a uniform texture (3-5mm depth) on existing concrete pavement to improve overlay adhesion.
Pavement Smoothing: Eliminates bumps, ripples, and other unevenness with an accuracy of ±2mm/3m, preparing for new asphalt paving.
Road Marking Removal: Precision milling of old road markings.
Airport Runway: High-precision surface treatment.
Typical Applications: Highway Maintenance: High-speed nighttime milling (operating speed 5-15m/min) to minimize traffic disruption. Municipal road reconstruction: Utilizing recycling technology, 100% recycling of old materials is achieved.
Airport runway maintenance: Special alloy teeth are used to handle high-strength concrete, with milling depths up to 50mm.
