The GZ4240X Double Column Gantry Type Band Saw Machine is a high-performance metal cutting solution designed for industries requiring high stability, precision cutting, and efficient production.
Featuring a double column gantry structure and rotary cutting mechanism, the machine provides excellent rigidity and allows the saw beam to rotate from 0° to 45° with automatic positioning, making it suitable for both straight cutting and angle cutting applications.
The GZ4240X combines mechanical structure, hydraulic transmission, PLC control, and human-machine interface technology to achieve safe, efficient, stable, and energy-saving cutting performance. It is widely used in bearing manufacturing, standard parts production, automotive components, and other metal processing industries.
With a maximum cutting capacity of 400mm diameter, four-speed blade adjustment, hydraulic feeding, hydraulic clamping, and automatic/manual dual operation modes, the machine provides a reliable solution for batch production and precision metal cutting.
Key Features
1. Double Column Gantry Structure for Superior Rigidity
The GZ4240X adopts a double column gantry structure, consisting of a strong base, two large circular columns, saw frame, transmission system, blade guiding system, and workpiece clamping mechanism.
The two large columns provide stable guidance for saw beam movement, ensuring smooth lifting operation and maintaining cutting accuracy during heavy-duty machining.
The machine base uses a box-type welded steel structure with vibration aging treatment, reducing welding deformation and improving long-term structural stability.
2. 0-45° Rotary Cutting Function
The GZ4240X is equipped with a rotary mechanism that enables the saw beam to rotate from 0° to 45° and automatically position at the required angle.
This function allows the machine to perform:
- Straight cutting
- Angle cutting
- Multi-angle metal processing
The rotary mechanism consists of a rotary shaft seat, positioning guide rail, and rollers, ensuring smooth and accurate angle adjustment.
3. High-Precision Hydraulic Feeding System
The machine adopts a hydraulic front feeding system with grating ruler positioning, providing accurate material positioning and stable feeding performance.
The hydraulic feed system allows stepless adjustment of feeding speed, enabling operators to select suitable cutting conditions for different materials and improve blade life.
The maximum single feeding length reaches 600mm, and multiple feeding operations can be performed for longer materials.
4. Advanced CNC Control System
The GZ4240X is equipped with a PLC control system, touchscreen interface, and sensors to control:
- Saw blade rotation
- Saw beam lifting
- Workpiece clamping
- Feeding and return movement
The machine supports both automatic and manual cutting modes, allowing flexible operation according to different production requirements.
Operators can set cutting length and quantity, and the machine will automatically complete the cutting cycle and stop after finishing the preset quantity.
5. Stable Hydraulic Clamping System
The GZ4240X uses hydraulic clamping combined with front and rear clamping structures to firmly hold the workpiece during cutting.
During operation, at least one clamp remains engaged, ensuring the material does not move during cutting and improving cutting stability.
The upper pressing device further improves clamping reliability, allowing materials to be securely fixed from multiple directions.
6. Precision Blade Guidance System
The blade guiding system consists of adjustable guide arms, guide rollers, and wear-resistant guide blocks.
The guide system helps maintain the blade perpendicular to the worktable, reduce vibration, and improve cutting accuracy.
The machine also uses high-precision saw wheels and reinforced tungsten steel clamping plates to ensure stable blade operation and cutting precision.
7. Efficient Bundle Cutting Capability
The GZ4240X is equipped with a bundle cutting device, allowing multiple workpieces to be placed together and cut simultaneously.
This function improves production efficiency, especially for batch cutting applications requiring high productivity.
The machine can cut multiple rows of materials within the permitted width and height range, significantly improving processing efficiency.
8. Material Saving and Long Blade Life
The machine uses imported bimetal band saw blades featuring:
- Narrow cutting kerf
- Reduced material waste
- Higher cutting efficiency
- Longer service life
The advanced guide head design reduces blade friction and helps prevent tooth damage, improving cutting speed and stability.
