The B-45 CNC Horizontal Band Saw Machine is a heavy-duty automatic metal cutting solution designed for high-efficiency and stable processing of large-diameter round bars, square blocks, steel plates, and bundled metal materials.
With a maximum cutting capacity of Ø450 mm for round materials and 450 * 450 mm for rectangular materials, the B-45 combines CNC control, hydraulic clamping, variable band speed, automatic feeding, and automatic chip removal to provide reliable performance for demanding metalworking applications.
The machine features a rigid cast-and-welded machine body, precision band-wheel balancing, tungsten-carbide band guides, hydraulic workpiece clamping, and a stable hydraulic lifting system. These design features help reduce vibration, improve cutting stability, extend blade life, and maintain consistent cutting performance during continuous production.
The B-45 also supports automatic feeding with magnetic scale positioning, with a single feed stroke of up to 600 mm and multiple feeding cycles for longer workpieces. A bundle-cutting function is available for customers who need to process multiple workpieces simultaneously.
Key Features
1. Large Cutting Capacity
The B-45 is designed for heavy-duty metal cutting, offering a maximum cutting capacity of:
- Round material: Ø450 mm
- Square/rectangular material: 450 * 450 mm
This makes it suitable for large steel bars, blocks, shafts, structural components, and other heavy metal workpieces.
2. CNC Automatic Feeding System
The machine uses a hydraulic rear feeding system with magnetic scale positioning, allowing accurate and repeatable material positioning.
The maximum single feeding stroke is 600 mm, while longer workpieces can be processed through multiple feeding cycles.
3. 20–100 m/min Variable Band Speed
The B-45 uses variable-frequency speed control, providing a band speed range of 20–100 m/min.
This allows operators to select suitable cutting speeds for different materials, workpiece sizes, and production requirements.
4. Full-Length Hydraulic Workpiece Clamping
The machine adopts full-stroke hydraulic clamping, providing stable workpiece holding during cutting.
Hydraulic clamping is particularly useful for large and heavy workpieces where secure positioning is essential for cutting accuracy and operational safety.
5. Rigid Machine Structure
The machine body uses a cast-and-welded structure designed to provide high stability during heavy-duty cutting.
The saw frame is manufactured from welded steel plates with reinforcing ribs and undergoes vibration stress treatment to reduce residual welding stress and improve structural stability.
6. Tungsten-Carbide Blade Guide System
The blade guide system uses tungsten-carbide guide components to provide high strength and wear resistance.
The guide system helps keep the blade aligned with the cutting direction while reducing blade deformation and friction-related vibration.
7. Automatic Chip Removal
An automatic screw-type chip conveyor removes saw chips from the cutting area and transfers them into the chip collection box.
The machine also features a powered steel brush for cleaning the saw blade, helping prevent secondary cutting caused by accumulated chips and reducing the risk of tooth damage.
8. Intelligent Hydraulic System
The hydraulic system controls key machine functions including:
- Saw frame lifting
- Workpiece clamping
- Material feeding
- Material return
The system uses a high-performance variable vane pump with automatic flow adjustment and compensation, helping provide stable operation and efficient hydraulic power transmission.
9. Multiple Safety Protection Functions
The B-45 incorporates multiple safety functions, including:
- Blade breakage automatic stop
- Overload protection
- Workpiece clamping detection
- No-material detection
- Automatic shutdown in case of blade jamming
The machine is designed so that the saw blade cannot start when the workpiece has not been properly clamped.
10. Manual & Automatic Operation
The control system supports both manual and automatic operation, allowing users to select the appropriate operating mode according to production requirements.
