· Strong power, ample torque, high speed, and fully arranged teeth working with movable teeth to achieve hard rock and no dead angle milling with high efficiency.

· The industry's first pump and air-combined slag discharge system can discharge slag quickly, even in deep trenches, accelerating speed, improving efficiency, and reducing the chances of pipe blocking simultaneously.

· The vertical rotation device of the frame ensures that the cutting wheel frame is upright, and 12 sets of deviation correction devices are equipped to provide high-quality grooving.

· Steady, continuous micro feed speeds up to millimeter level, which can perfectly meet the needs of slow feed in complex rock construction.

· Correction cylinder with large diameter and long stroke enables significant thrust, which can meet the needs of hard stratum and significant deviation rectifying.

· Cutting wheel speed, torque, winch load, and milling speed are self-adaptive to maximize construction efficiency. Drilling and mud pump discharge power can be automatically adjusted to optimize power utilization.

· the mud capstan is automatically deflected to ensure that The capstan direction is consistent with the pipe inlet angle to avoid mud pipe wear and prolong the service life of the mud pipe.

· The flexible design of the mast cylinder can effectively prevent vibration from being transmitted to the cab during the construction of the working device, making driving smooth.

· In corner construction, the rotating function of the working device ensures that the active device can quickly enter the groove.

· When disassembling and transferring, mud and oil pipes can be completely retracted from the capstan and transported with the capstan on a unique transport rack.

· Steel ring structure mud pipe is explosion-resistant and wear-resistant with a long service life. The fixed end of the wire rope is equipped with a torque release device to ensure a stable internal structure and long service life.
