XWV50 Vertical 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.

When choosing the radial interval between the tip of the cutting teeth, it is necessary to take into account the supporting condition of the cutting teeth at each position. The primary function of the cutting teeth located at the top is to maintain the impact of the milling and digging head on the transverse pendulum laser cutting body. The key of the cutting teeth located at the transition section is to make the milling and digging head have a shallow to deep milling and digging whole process in the transverse milling and digging. Reduce the impact load of milling and digging head of small hydraulic milling and digging machine. Because of the standard deviation of milling and digging at the top and over the wavelength cutting gear, the friction resistance of milling and digging is large, the minimum turning radius of milling and digging is small, and the bearing capacity of the single cutting gear is large, the radial interval of the tooth tip should be selected. The milling and digging knife located in the parallel line segment should shoulder the specific daily task of milling and digging, and the radial interval of the tooth tip should be selected to improve the efficiency of the tunnel hydraulic milling and digging machine. In general, the radial interval between the tips of the picks located at the top and the transition section should be reduced successively according to the change of inclination, while the radial interval between the tips of the picks located at the middle section of the parallel line is larger.

The cutting teeth bear high compressive stress, shear stress and impact load when laser cutting rock, and raise the temperature of the cutting teeth, resulting in softening of the meshing Angle material and speeding up the invalid process of the cutting teeth. According to the shape characteristics and wear level, the ineffective ways of cutting teeth can be divided into four categories: symmetrical wear of teeth, non-uniform wear of teeth, head falling off and head fracture. In a few cases, tooth fracture will continue to occur.
