GB4240 Main Auxiliary Column Horizontal Band Saw Hydraulic For Metal Steel

The GB4240 Horizontal Metal Band Saw Machine is a heavy-duty horizontal band saw designed for cutting a wide range of metal workpieces, including round tubes, square tubes, plates and other conventional metal materials. It is particularly suitable for small- and medium-batch material preparation where cutting efficiency and accuracy are important.
The machine features a hydraulic workpiece clamping system, hydraulic saw-frame lifting, hydraulic stepless feed adjustment and a roller-type material support rack. The workpiece can be loaded from the rear of the machine and positioned for cutting through the integrated electrical and hydraulic control system.

The GB4240 uses a welded box-type machine structure and a reinforced welded saw frame that has undergone vibration aging treatment to help reduce welding stress and improve structural stability. Its blade guide system uses adjustable guide arms, guide bearings and wear-resistant guide blocks to support stable blade movement during cutting.

Key Features

Hydraulic Workpiece Clamping
The GB4240 uses a full hydraulic cylinder clamping system. Operators can control workpiece clamping and release through buttons on the control panel, providing convenient operation for different metal materials.

Hydraulic Stepless Feed Adjustment
The saw-frame feed speed is controlled hydraulically with stepless adjustment, allowing the operator to adjust the cutting feed according to different workpiece and cutting requirements.

400 mm Maximum Round Cutting Capacity
The GB4240 has a maximum specified round cutting diameter of Ø400 mm and a maximum rectangular cutting capacity of 500 * 400 mm.

Four Blade Speed Options
The machine provides four blade speeds of 30 / 45 / 60 / 80 m/min, allowing operators to select an appropriate speed for different cutting conditions.

Stable Welded Machine Structure
The machine bed adopts a steel-plate welded box-type structure. Vibration aging treatment is used to redistribute and reduce welding stress, helping improve the stability of the machine structure.

Reinforced Saw Frame
The saw frame uses a bow-shaped structure made from welded high-quality steel plates with reinforcing ribs. After vibration aging treatment, the structure is designed to maintain stability during operation.

Adjustable Blade Guide System
Both left and right guide arms can move along the dovetail guide structure, allowing the guide-arm spacing to be adjusted according to the workpiece size. Guide bearings, wear-resistant guide blocks and a dual-bearing blade-back support help guide the blade during cutting.

Roller-Type Material Support
The standard configuration includes a roller-type material support rack, helping simplify workpiece positioning and material handling during cutting.

Integrated Hydraulic System
The hydraulic system consists of pumps, valves, cylinders, an oil tank, pipelines and an integrated hydraulic block. It controls functions including saw-frame lifting, workpiece clamping, feeding and material return.

FAQ
Q1: 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.
Q2: What is your factory acceptance test method?
A: You can send us sample material to be cut, and we will perform a test cut using our machine. After the test is complete, we will provide you with detailed cutting data. (We will also send you a video of the machine cutting operation for your confirmation.)
Q3: Where is your factory located?
A: Our factory is located in Nantong City, Jiangsu Province, China. It will takes about 1.5 hours from Shanghai Hongqiao station to our city.

Q4: How does the GB4240 clamp workpieces?
A: The machine uses a hydraulic workpiece clamping system. Operators can control clamping and release through the control panel.

Q5: Can the feed speed be adjusted continuously?
A: Yes. The saw-frame feed speed uses hydraulic stepless adjustment, allowing operators to select a suitable feed rate for different workpieces and cutting conditions.
