XW90 Horizontai Drum Cutter

The XW milling and excavating machine can be installed on any type of hydraulic excavator, efficiently replacing general configurations such as digging buckets, crushing hammers, and hydraulic shears. It is applied in multiple fields such as open-pit coal mines, tunnel excavation and contour correction, channel groove milling, asphalt concrete pavement milling, rock permafrost milling, and tree root milling. The milling and excavating machine provides a new construction method for tunnel excavation.

Features of XW milling and excavation machine:

1. Wide range of milling and excavation;

2. Low vibration and low noise;

3. Accurately control construction;

4. The material excavated by milling has a small and uniform particle size, which can be directly used as backfill material;

5. Good safety;

6. Simple structure and convenient use.

In order to better design to achieve a variety of working conditions of the hydraulic hydraulic milling and digging machine, only the design of the milling and digging machine can work normally under extremely harsh working conditions, then the milling and digging machine is high quality. In this paper, according to the whole process of the milling and digging machine to carry out three-dimensional dynamic simulation, get the milling and digging cutter in the specific work of the stress condition, then according to the analysis of the milling and digging cutter force to improve the structure of the milling and digging head.

In this paper, the whole working process of the milling and digging machine under the extreme working standard is simulated, that is, the small hydraulic milling and digging machine is simulated to mill and dig hard rock. According to the analysis of the force of each milling and digging knife in hard rock milling, the specific guidance of the lifting of the milling and digging head is improved. Although it only imitates the whole process of hard rock milling and digging by the milling and digging machine, it is enough to design the milling and digging machine that reaches the key point of design. When milling and digging other low and medium strength raw materials, the force of the milling and digging head and the milling and digging tool is far lower than the designed value. Therefore, this paper will carry out dynamic simulation of two working conditions of milling and digging machine milling and digging hard rock, that is, milling and digging machine drilling into milling and digging hard rock and milling and digging machine milling across hard rock.
