The GB4265 Gantry Type Horizontal Metal Band Saw Machine is a heavy-duty metal cutting machine designed for large-diameter and large-section workpieces. It is mainly used for cutting round billets, large cylindrical components, shafts, square forgings and other large metal workpieces.
With a maximum cutting diameter of 650 mm, the GB4265 is designed for demanding metal sawing applications involving various ferrous metals. The machine combines a rigid gantry-style structure, hydraulic workpiece clamping, hydraulic stepless blade feed and platform-type material feeding to provide stable and efficient cutting performance.
The GB4265 features a dual-column gantry structure with linear guide rails and dual hydraulic cylinders for saw-frame lifting. The front and rear workpiece vises are hydraulically driven and can be independently controlled, helping secure large workpieces during cutting.
The machine uses a platform trolley-type feeding system, with a 1500 * 650 mm material trolley, making it suitable for handling large and heavy workpieces.

Key Features

1. Heavy-Duty Gantry Structure

The GB4265 adopts a welded dual-column gantry structure designed to improve overall machine stability. Each column is equipped with linear guide rails, while the saw frame is driven by two hydraulic cylinders simultaneously for stable vertical movement.

2. 650 mm Maximum Cutting Diameter

The machine provides a maximum specified cutting diameter of Ø650 mm, making it suitable for large round workpieces, billets, shafts and other heavy metal components.

3. Hydraulic Stepless Blade Feed

The blade feed speed is controlled by a hydraulic stepless adjustment system. This allows operators to continuously adjust the cutting feed according to material type, workpiece dimensions and cutting conditions.

4. Three Blade Speeds

The GB4265 provides three blade speeds through a belt-pulley speed adjustment system:

• 22 m/min
• 45 m/min
• 65 m/min

This allows operators to select an appropriate blade speed for different metal-cutting applications.

5. Hydraulic Double-Vise Clamping

The machine uses front and rear hydraulic workpiece vises. The two clamping vises can be independently controlled to secure the workpiece and help maintain cutting stability and accuracy.
For special materials or applications, an optional upper gantry clamping system is available.

6. Platform Trolley-Type Feeding

The GB4265 uses a platform trolley-type material feeding system. The standard material trolley measures 1500 * 650 mm, providing a stable platform for large workpieces.

7. Rigid Welded Saw Frame

The saw frame adopts an arch-shaped structure made from high-quality steel plates with reinforcing ribs. After vibration stress-relief treatment, welding stresses are redistributed and reduced to improve the stability of the saw frame during operation.

8. Carbide Blade Guide System

The guide system consists of a fixed guide arm and a movable guide arm. The movable guide arm can be manually adjusted according to workpiece dimensions.
The guide seat uses carbide components on the top and side, while an additional pre-guide system helps stabilize the blade and extend blade service life.

9. Hydraulic Automatic Blade Tensioning

The GB4265 uses hydraulic automatic blade tensioning. After the band saw blade is installed, the tensioning cylinder drives the tension wheel to apply the required blade tension.

10. Circulating Coolant System

The machine uses a centralized cooling pump with multiple cooling points positioned around the blade guide arms and above the saw blade. The coolant is continuously circulated during operation to help reduce blade heat and support stable cutting.

11. Automatic Chip Cleaning

A passive chip-cleaning wheel is provided to remove metal chips from the band saw blade during operation, helping maintain cleaner blade teeth and support continuous cutting.

12. Button-Controlled Operation

The machine uses a centralized electrical control cabinet and button-based operation. The different machine movements are controlled through relays and interlocking functions to improve operational safety.

Technical Specifications

Application

The GB4265 is designed for large and heavy metal cutting applications, particularly where a conventional horizontal band saw does not provide sufficient cutting capacity or workpiece support.

Typical Applications

• Large round billet cutting
• Large cylindrical workpiece cutting
• Shaft cutting
• Square forging cutting
• Large-section steel cutting
• Heavy metal stock preparation
• Steel and alloy processing
• Heavy machinery manufacturing
• Metal fabrication
• Industrial metalworking

The machine is specifically described as suitable for cutting round-disc workpieces, large cylindrical parts, shafts, square forgings and other black-metal materials. Its narrow saw kerf also helps reduce material waste during cutting.
