Asphalt cutter head of milling machine 128302

Milling damaged old pavement layers with a road milling machine and then laying new pavement layers is the most economical modern maintenance method. Due to its high work efficiency, simple construction process, easy control of milling depth, convenient and flexible operation, good maneuverability, and direct recycling of milled old materials, it is widely used in urban municipal roads and highway maintenance projects. A general milling machine consists of an engine, frame, milling rotor, milling depth adjustment device, hydraulic components, aggregate conveying device, steering system, and braking system.

The milling rotor is the main working component of a milling machine, which is composed of the milling rotor shaft, cutter seat, and cutter head. It directly contacts the road surface and works through its high-speed rotating milling cutter to achieve the purpose of milling. The milling machine is equipped with an automatic leveling device, which uses the milling rotor side cover as the milling reference plane and controls two positioning hydraulic cylinders to maintain a constant milling depth.
