XW50 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.

Because of the uniqueness of the milling and digging target of the milling and digging machine, the large usage of the milling and digging tool of the longitudinal hydraulic milling and digging machine and the low efficiency of milling and digging have become prominent problems in the construction process of tunnel construction, surface and mining engineering. This is also a major difficulty encountered by employees engaged in scientific research and design of milling and digging machines around the world.

Among the main parameters of construction that harm the working efficiency of milling and digging machine, the harm of cutting Angle is more prominent. The analysis of tunnel lateral milling and digging machine tool load, different cutting Angle of the turning tool and cutter head stress and internal stress throughout, for scientific research milling and digging machine working in the ineffective reason and damage principle of the tool, improve the milling and digging cutter and cutter head design scheme, improve its service life and operating stability, processing milling and digging machine low efficiency of the problem has the key practical significance. According to the calculation of the force of the milling and digging cutter milling and digging rock, the force value of the milling and digging cutter under different cutting Angle and different cross section rate is clarified: the selection of Pro/E to establish the solid model of the milling and digging cutter and each cutter seat, and guided into the Pro/Mechanica, the analysis of the internal stress of the milling and digging cutter under different cutting Angle and different cross section rate. According to the careful analysis of the effect, the best cutting Angle of milling and digging tool is selected, which lays the foundation for the establishment of milling and digging head.
