GB42150 Gantry Horizontal Band Saw Machine With Hydraulic Platform Feeding

The GB42150 Gantry Horizontal Band Saw Machine is a heavy-duty metal cutting machine designed for large-scale and continuous sawing applications.

With a maximum cutting capacity of Ø1500 mm for round materials and 1500 * 1500 mm for square materials, the machine is designed for cutting large steel billets, seamless steel pipes, large shafts, and other oversized metal workpieces.

The GB42150 features a rigid dual-column gantry structure, powerful reducer-driven transmission, hydraulic clamping, hydraulic blade tensioning, variable-speed blade control, and a hydraulic platform automatic feeding system.

The machine is designed for efficient semi-automatic operation and can be used for long-term continuous production. With appropriate cutting parameters, it can also be used for ferrous and non-ferrous metals, round materials, and square materials.

Its robust structure, high rigidity, reliable hydraulic system, adjustable cutting speed, and automatic feeding functions make the GB42150 suitable for demanding heavy-duty metal cutting applications.

The machine is manufactured according to the current industry standard JB/T4318.1–4-2013 for horizontal band saw machines and is equipped with reliable safety protection systems.

The GB42150 adopts a dual-column gantry structure designed for large and heavy workpieces.

The machine consists of a heavy-duty base, saw frame, saw frame lifting system, blade tensioning system, main transmission system, moving platform, guide-arm system, blade guide system, workpiece clamping system, hydraulic system, cooling system, and electrical control system.

The reinforced structure provides high static and dynamic rigidity, helping reduce vibration and maintain stable cutting performance during heavy-duty operations.

This large cutting capacity makes the machine suitable for applications that cannot be handled by conventional metal band saws.

A major feature of this version is its hydraulic platform feeding system.

The hydraulic platform helps move large and heavy workpieces while reducing manual material handling and operator workload.

This design is particularly useful when processing large steel billets, pipes, shafts, and other heavy materials.

The main drive motor is rated at 18.5 kW, providing strong cutting power for large workpieces. The blade speed is controlled by a vector frequency converter and can be continuously adjusted within the range of 20–80 m/min.

This allows the operator to select appropriate blade speeds for different materials and cutting conditions.

During no-load descent, the fast-down hydraulic circuit allows the saw frame to approach the workpiece quickly, reducing auxiliary operation time.

The dual-column and dual-cylinder design provides stable saw frame movement during heavy-duty cutting.

The blade tension can be preset by adjusting hydraulic pressure.

The system allows the blade to be tensioned when the machine is powered on and released when powered off, helping improve blade fatigue conditions and extend blade service life.

The machine uses a vector frequency converter to control blade speed.

The blade speed can be continuously adjusted from 20 to 80 m/min, allowing operators to adapt the cutting speed to different materials, dimensions, and cutting requirements.

These systems are designed to improve sawing efficiency and help reduce operating costs.

The machine also monitors the main motor load. When an overload condition occurs, the system can automatically disconnect the power for protection.

The guide arms are hydraulically driven and can move along the guide rails.

After reaching the required position, the guide arms can be hydraulically locked.

This makes guide-arm adjustment more convenient and reduces auxiliary setup time when processing workpieces with different dimensions.

The blade guide system uses reinforced adjustable tungsten-carbide guide plates.

The guide structure helps maintain blade stability and improve cutting accuracy.

It is also designed to improve the force conditions of the blade when twisting occurs, reduce deformation and friction-related noise, and extend blade service life.

The machine is equipped with an automatic blade-break detection and shutdown function.

When blade breakage is detected, the machine can automatically stop operation.

This helps protect the machine and workpiece while reducing the risk of continued operation after blade failure.

The GB42150 is designed primarily for large-scale and heavy-duty metal cutting.

Suitable for cutting oversized steel billets where high machine rigidity and powerful cutting performance are required.

The large cutting capacity makes the machine suitable for large-diameter seamless steel pipe processing.

Suitable for cutting large-diameter shafts and other heavy round workpieces.

The machine can process square materials up to 1500 * 1500 mm, making it suitable for large metal blocks and structural components.

With suitable cutting parameters, the GB42150 can also be used for selected ferrous and non-ferrous metal materials.

The machine is designed for long-term continuous operation and can be used for year-round production in demanding industrial environments.
