GB4280 Double Column Horizontal Band Saw 800mm Metal Cutting Machine

The GB4280 Gantry Type Horizontal Bandsaw Machine is a heavy-duty metal cutting solution designed for large-diameter round billets, cylindrical workpieces, shafts, square blocks, and forged metal components.

Featuring a rigid dual-column gantry structure, the GB4280 provides stable support during heavy-duty cutting operations. Its reinforced welded frame undergoes vibration stress relief treatment to reduce residual welding stress and improve structural stability.

The machine is equipped with a hydraulic dual-clamping system, variable-frequency blade speed control, and stepless hydraulic feed adjustment, allowing operators to optimize cutting conditions according to different material requirements.

With a maximum cutting capacity of Ø800 mm or 800 × 800 mm, the GB4280 is suitable for industrial manufacturers handling large-sized ferrous metal materials. Its automatic hydraulic blade tensioning, circulating coolant system, and powered feeding arrangement further support efficient and stable cutting operations.

1. Heavy-Duty Gantry Dual-Column Structure

The machine adopts a reinforced welded dual-column gantry structure to provide stable support during large-workpiece cutting. The welded frame undergoes vibration stress relief treatment to reduce internal stress and improve structural stability.

2. Large Cutting Capacity

With a maximum cutting capacity of Ø800 mm or 800 × 800 mm, the GB4280 is designed for large round bars, square blocks, shafts, and heavy metal components.

3. Variable Frequency Blade Speed Control

The bandsaw blade speed is adjustable from 25 to 80 m/min through a variable frequency drive (VFD), allowing flexible speed selection according to different material types and cutting conditions.

4. Hydraulic Stepless Feed Adjustment

The hydraulic feed system allows stepless adjustment of the saw frame feeding speed, helping operators optimize cutting conditions and maintain stable cutting performance.

5. Hydraulic Dual Clamping System

The machine features front and rear hydraulic clamping vises to securely hold workpieces during cutting. The dual-clamping arrangement improves workpiece positioning and helps maintain cutting stability.

6. Hydraulic Automatic Blade Tensioning

The hydraulic tensioning system uses a hydraulic cylinder to drive the tensioning wheel, applying appropriate tension to the bandsaw blade and helping maintain stable blade operation.

7. Dual Hydraulic Cylinder Saw Frame Drive

The saw frame is lifted and lowered by two hydraulic cylinders. Combined with the linear guide rail system, this structure supports smooth and stable vertical movement.

8. Hydraulic Movable Guide Arm

The movable blade guide arm is driven hydraulically to accommodate different workpiece widths. The guide arm is secured by a manual locking mechanism after adjustment.

9. Carbide Blade Guide System

The upper and side surfaces of the blade guide seats use carbide components to improve wear resistance and blade guidance stability. An additional pre-guiding device helps maintain proper blade positioning.

10. Circulating Coolant and Chip Cleaning System

The centralized coolant system supplies cutting fluid to the blade guide areas and cutting zone. A passive cleaning wheel removes chips adhering to the bandsaw blade, helping maintain cutting performance and extend blade service life.

11. Motorized Feeding System

The machine is equipped with a powered feeding arrangement to facilitate workpiece handling and feeding operations, reducing manual handling requirements during production.

12. Independent Hydraulic and Electrical Systems

The independent hydraulic power unit provides hydraulic power for machine operations. The electrical control system uses relay-based control and interlocking functions to support safe and reliable operation.

Q1: Are you a manufacturer or a trading company?

A: We are a professional manufacturer of saw blade grinders. We have a 30,000 square meter factory and a team of dedicated technicians specializing in design, manufacturing, and sales.

Q2: What is your method of transaction?

A: We adopt the FOB(Free ON Board) transaction.

Q3: How about your delivery time?

A: Generally, it will take 7-60 work days after receiving your order. The specific delivery time depends on the items and the quantity of your order.

Q4: Can the guide arm be adjusted for different workpiece sizes?

A: Yes. The movable guide arm is hydraulically driven, allowing it to move according to the workpiece width. After adjustment, a manual locking mechanism secures the guide arm in position.

Q5: What is the purpose of the circulating coolant system?

A: The coolant system supplies cutting fluid to the blade guide areas and cutting zone. It helps control cutting temperature, reduce friction, and extend bandsaw blade service life.
