XW500 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.

Elevation Angle r is the intersection Angle between the axis of the milling and digging tool at the actual position and the reference position. The reference position is the position of the milling and digging tool when the bottom line of the milling and digging tool seat of the geotechnical hydraulic milling and digging machine is parallel to the tangent line of the cutting track at the tool tip. The function of elevation Angle is mainly used to adjust the cutting Angle of the milling cutter, directly affect the force of the milling cutter, and determine the different elevation Angle so that each milling cutter has the same cutting Angle.

The objective of the design of the installation parameters of the chain type hydraulic milling and digging machine and the milling and digging knife block is:

(1) Make the milling and digging head meet the requirements of the milling and digging tool arrangement design:

(2) Make each milling and digging knife have the space attitude to realize the best milling and digging:

(3) It is feasible and reasonable for each milling and digging tool block to cooperate with the surface of milling and digging hub.

The installation parameters of milling cutter are distributed in three-dimensional space, which is difficult to be realized by conventional design method. Therefore, the method of space coordinate transformation is used to design.
