The GY42100 adopts a gantry-type double-column structure, with the saw frame suspended between two vertical columns, ensuring uniform force distribution during cutting. It relies on a high-speed rotating band saw blade and stable hydraulic feeding to achieve precise cutting of large workpieces. The machine is primarily used for cutting thick metal materials such as large-diameter round steel, extra-large square steel, thick-walled pipes, and H-beams. Its body is made of high-strength cast iron with reinforced ribs, subjected to multiple aging treatments to eliminate internal stress—this ensures minimal deformation even under long-term heavy loads, laying a foundation for stable cutting accuracy.

Structural Features

• Double-Column Gantry Structure: The gantry-type columns and reinforced bed form a rigid frame, capable of withstanding huge cutting forces during heavy-duty operations. This structure minimizes vibration and displacement, ensuring the flatness of the cutting surface and reducing saw blade wear.
• High-Power Saw Blade Drive System: The main drive uses a high-torque motor paired with a precision gearbox, driving the band saw blade to rotate at adjustable speeds. The saw blade guide device is equipped with wear-resistant alloy guide blocks and pressure rollers, which firmly clamp the saw blade to prevent deflection during high-speed cutting, thus extending the saw blade’s service life.
• Hydraulic Control System: The entire machine is controlled by a hydraulic system, integrating functions such as workpiece clamping, saw blade feeding, and saw blade tensioning. The hydraulic clamping device uses multi-point clamping to securely fix extra-large or irregular workpieces, avoiding movement during cutting. The hydraulic feeding speed is steplessly adjustable, allowing operators to optimize cutting parameters based on material hardness.
• Large Worktable and Loading Assistance: The worktable is a large-area cast iron platform with a high load-bearing capacity (up to several tons), designed to accommodate extra-large workpieces. Some models are equipped with auxiliary loading rollers or lifting devices to simplify the handling of heavy materials, reducing labor intensity.
• Intelligent Operation Panel: The control panel features a digital display screen that shows key parameters such as saw blade speed, feeding rate, and cutting depth in real time. It supports both manual operation and semi-automatic cutting (e.g., presetting cutting length for batch processing), with emergency stop buttons and overload protection to ensure operational safety.
