In the field of heavy equipment manufacturing, as workpiece sizes continue to increase and higher requirements are placed on machining accuracy and stability, machine tools are facing greater challenges.

Recently, a 36-meter Moving Column & Moving Beam Gantry Milling Machine by Shuochao CNC has been successfully installed at the customer’s site and is now in operation.

The main technical specifications of the machine are as follows:

Width clearance: 10 meters

Height clearance: 8 meters

Total machine length: 36 meters

The machine is mainly used for machining large flanges, tube sheets, and heavy structural components, and is widely applied in industries such as wind power equipment, petrochemical, pressure vessels, and heavy steel structures.

1. Key Challenges in Large Workpiece Machining

In the machining of large-scale components, manufacturers commonly face the following challenges:

Limited machine capacity for large dimensions
Conventional machine tools are often unable to handle oversized workpieces, requiring segmented machining, which affects both efficiency and accuracy.

High rigidity requirements under heavy-duty machining
Under high cutting forces, the structural rigidity of the machine directly impacts machining accuracy and service life.

Balancing efficiency and precision
Achieving both high precision and high efficiency remains a key challenge in practical production.

2. Technical Advantages of Moving Column & Moving Beam Structure

To address these challenges, the moving column & moving beam gantry structure offers significant advantages:

Flexible configuration for machining extra-large workpieces

High structural rigidity for heavy-duty cutting conditions
