The machine integrates mechanical structure, hydraulic transmission, PLC control system, and human-machine interface technology to achieve safe, efficient, stable, and energy-saving cutting performance.
Equipped with hydraulic feeding, hydraulic clamping, automatic and manual operation modes, and precision positioning through a grating ruler system, the GZ4240 provides reliable performance for both batch production and flexible manufacturing requirements.
Key Features
1. Large Cutting Capacity for Industrial Applications
The GZ4240 CNC band saw machine is designed for heavy-duty metal cutting, with a maximum cutting capacity of:
- Round material: Φ400mm
- Plate material: 400mm
It is suitable for processing larger metal components used in machinery manufacturing, automotive parts, bearing production, and other industries.
2. High-Rigidity Machine Structure
The machine adopts a robust structural design consisting of:
- Base
- Machine bed
- Column structure
- Saw frame
- Transmission system
- Blade guiding device
- Workpiece clamping mechanism
The machine base adopts a box-type welded steel structure with vibration aging treatment, reducing welding deformation and improving long-term stability.
The saw frame adopts a welded steel plate structure with reinforced ribs and stress-relief treatment, ensuring excellent rigidity and stable operation during cutting.
3. Automatic CNC Cutting System
The GZ4240 is equipped with a PLC control system, touchscreen interface, grating ruler, and sensors to control:
- Saw blade rotation
- Saw frame lifting
- Workpiece clamping
- Feeding and return movement
The system enables automatic cutting cycles according to preset parameters, improving production efficiency and reducing operator workload.
The machine supports both automatic and manual cutting modes, allowing flexible operation according to different production requirements.
4. Hydraulic Feeding and Precision Positioning
The GZ4240 adopts hydraulic rear feeding with grating ruler positioning, ensuring stable and accurate material positioning during continuous cutting.
The feeding system supports:
- Single feeding length up to 600mm
- Multiple feeding operations for longer materials
This design improves cutting efficiency and ensures consistent processing results.
5. Stable Hydraulic Clamping System
The machine uses hydraulic clamping to firmly secure the workpiece during cutting.
The front and rear clamping system works together to maintain material stability during operation.
During cutting, at least one clamping mechanism keeps the workpiece fixed, reducing movement and improving cutting accuracy.
6. Precision Blade Guidance System
The blade guide system uses adjustable guide arms, guide rollers, and wear-resistant guide blocks to improve blade stability.
The guide structure helps maintain blade verticality, reduce vibration, and improve cutting precision.
The machine also uses high-precision blade wheels and reinforced tungsten steel clamping pieces to ensure cutting accuracy.
7. Efficient and Material-Saving Cutting
The GZ4240 uses bimetal band saw blades, which provide:
- Narrow cutting kerf
- Lower material waste
- Higher cutting efficiency
- Longer blade service life
The machine is suitable for continuous production and batch cutting applications.
8. Intelligent Operation and Easy Maintenance
The PLC control system with touchscreen operation allows operators to easily set cutting parameters and monitor machine status.
The system supports setting multiple cutting programs and automatic counting functions, significantly reducing labor intensity.
