H2-33N Fully Automatic Horizontal Metal Band Sawing Machine

Product Overview

The H2-33N Fully Automatic Horizontal Metal Band Sawing Machine is a high-performance industrial cutting solution engineered for precise and efficient metalworking operations.

Offering a robust cutting capacity of up to 330mm for round materials and 330×330mm for square/flat workpieces, this machine is driven by a powerful 4 kW main motor to handle demanding processing tasks.

Built with a heavy-duty welded foundation and incorporating integrated hydraulic, cooling, and electrical systems, the H2-33N delivers high-precision cutting with a single feeding accuracy of ±0.2 mm, making it an ideal choice for high-precision manufacturing environments.

Core Features & Structural Advantages

1. High-Rigidity Heavy-Duty Construction

• Stable Welded Machine Feet: Constructed from robust welding pieces, the machine base meets the foundation securely to bear the substantial weight of both the machine itself (1400kg) and heavy workpieces. It internally houses the integrated hydraulic and cooling systems.
• Durable Saw Frame: Fabricated from welded plates, the saw frame serves as the structural core to install the main driving system, maintain optimal saw blade tension, and house the blade guidance mechanisms.
• Precision Turn Table & Work Table: The turn table assembly consists of a base, turn table, and a turning axle featuring a rotating scale fixed directly to the machine body. The work table is maintained perfectly smooth and level, acting as the primary foundation to guarantee absolute workpiece precision.

2. Advanced Transmission & High-Precision Cutting

• Worm Wheel Main Transmission: The primary drive system utilizes a worm wheel driving mechanism composed of the main motor, worm wheel, and saw wheel to effectively transmit torque and drive the saw blade. According to your requirements, cutting speeds can be selected from 20, 40, 52, or 75 m/min, with adjustments made via the pulley belt setup to match various workpiece characteristics.
• Scissors Point Pivot: Connecting the saw frame and the work table, this scissors-type band saw pivot delivers the structural stability required for high-precision cutting tasks.
• Rigid Saw Blade Guidance System: Composed of a beam, guiding arm, guiding head, guiding block, alloy block, and alloy pieces. Turning the bearing of the guiding head keeps the saw blade strictly vertical to the work table. The alloy blocks and pieces minimize friction on the back and sides of the blade, while an integrated spring supports the alloy block to adjust cutting resistance. The guiding arm locks securely onto the beam and moves laterally to minimize the distance between guiding heads, maximizing blade rigidity and flexibility to significantly prolong blade service life.

3. Smart Feeding & Hydraulic Clamping

• Hydraulic Clamping Vice: Features an integrated feeding roller and board for material feeding and receiving. The clamping mechanism includes a fixed vise positioned on the right side of the table and a flexible vise controlled by a hydraulic cylinder to hold the workpiece tightly on the work table.
• High Feeding Accuracy: Delivers an automated single feeding accuracy of ±0.2 mm for repeatable precision.
• Manual Blade Tensioning: Features an adjustable manual tensioning system consisting of a driven pulley, tension sets, a lead screw, and a slider block, allowing operators to easily tune the tension using a wrench.

4. Fully Integrated Support Systems

• Efficient Cooling System: Utilizes a 3-phase electric pump (40W), a dedicated water storage tank, and a delivery line to ensure continuous cooling liquid supply during sawing, enhancing precision and extending blade life.
• Complete Hydraulic System: Equipped with an oil storage tank, motor (0.75 kW), gear pump, relief valve, magnetic valve, throttle valve, pressure gauge, filter, up-and-down cylinder, and a clamping cylinder.
• Industrial Electrical System: Integrates the main motor, oil motor, cooling motor, position switches, wiring board, branch box, operation box, operation panel, electrical elements, and heavy-duty cabling.
