Axial Milling Machine for Confined Spaces​

Axial Milling Machine for Confined Spaces​

Product Introduction

The longitudinal milling machine, also known as the vertical milling machine or trench milling machine, is a professional model specializing in longitudinal drilling, trenching, and finishing narrow channels. The rotation axis of its cutter head is basically parallel to the direction of the mechanical arm, achieving precise, efficient, and low-impact linear milling operations. It perfectly overcomes the limitations of traditional blasting and impact excavation in terms of precision, safety, and environmental protection, making it one of the core equipments for modern refined construction.

Product Features and Advantages

1. Precise, Efficient, and Safe Construction​
   • High-precision control: Enables millimeter-precise excavation, with the width, depth, and slope of trenches formed in one go, greatly reducing subsequent finishing work.
   • Expert in confined spaces: Designed specifically for narrow trenches, ideal for pipeline embedding and foundation construction.
   • Safer construction: Non-blasting operation effectively prevents accidental damage to surrounding structures and underground utilities, ensuring construction safety.
2. ​Low Impact, High Environmental Protection​
   • Low vibration, low noise: Minimal disturbance to the surrounding environment, making it the optimal choice for sensitive areas like urban centers, transportation hubs, and areas near important facilities.
   • Small milling particles for direct backfilling: The unique cutter head design breaks materials into uniform, fine particles that can be directly used as high-quality backfill, significantly reducing waste transport and disposal costs, enabling a green and economical construction cycle.
3. ​Versatility, Flexibility, and Efficiency​
   • Powerful modular design: Different attachments, such as standard milling heads, narrow trench-specific milling wheels, and high-strength rock saw blades, can be quickly changed according to specific working environments and geological conditions. Simple and convenient attachment changes allow one host machine to handle various complex working conditions.
   • Strong power output: Equipped with a high-torque hydraulic system, ensuring efficient milling capability when facing various materials from soft soil to medium-hardness rock.

Core Application Range

• Various rock and soil: Medium-hardness rock, weathered rock, gypsum, coal rock.
• Concrete structures: Concrete containing a small amount of reinforcement (e.g., pavements, foundations, walls).
• Special materials: Iron slag, frozen soil, and other recycled materials.

Typical Application Fields

• Municipal pipeline engineering: Precise trench excavation for power, communication, gas, water supply, and drainage pipelines.
• Tunnel and underground space: Precise formation and contour trimming of cable trenches and drainage ditches within tunnels.
• Building and foundation construction: Strip foundation excavation for building foundations, slope trimming.
• Road and airport maintenance: Precise “minimally invasive” repair of locally damaged asphalt or concrete pavements.
• Mining and special engineering: Working face trimming or channel excavation in coal mines, gypsum mines, etc., and handling of industrial waste like iron slag.
