MFG H-65/70S Semi-Automatic Horizontal Band Saw

650x700mm Capacity, Heavy-Duty Double-Column Frame & 54mm Wide Blade

Product Overview
The MFG H-65/70S is a massive, heavy-duty semi-automatic horizontal band saw engineered for high-capacity industrial metal fabrication.

Boasting a large cutting capacity of 650x700mm, it is specifically designed to process large metal profiles, heavy solid tubes, steel billets, and mold blanks.

Driven by a powerful 7.5 kW main motor and utilizing a heavy-duty 54mm wide bi-metal band saw blade, this machine is an essential, high-efficiency cutting solution for metallurgy, mining, shipbuilding, and heavy machinery manufacturing.

With its robust double-column architecture, centralized hydraulic control, and automated cycle return, the H-65/70S guarantees exceptional stability and precision during the heaviest cutting applications.

Key Features & Engineering Details

• Massive Double-Column Architecture: The saw frame is supported by a heavy-duty main cylindrical column and a secondary square sub-column. This highly rigid horizontal structure guarantees absolute stability, ensuring sufficient load-bearing margins and eliminating vibration during the sawing of massive 650mm billets.
• Heavy-Duty 54mm Blade System: Unlike smaller saws, the H-65/70S utilizes a wide 6150 x 54 x 1.6 mm band saw blade. The 54mm width provides exceptional beam strength, preventing blade deflection when cutting through dense, large-diameter alloys.
• Centralized Hydraulic System & Clamping: The machine features a comprehensive hydraulic circuit powered by an independent 1.5 kW motor. Workpieces are securely clamped via a heavy-duty hydraulic vise, ensuring zero material movement during high-torque cutting.
• Stepless Hydraulic Feed Regulation: Through a highly responsive hydraulic speed control valve, operators can achieve stepless, infinite speed regulation of the saw frame's downward feeding rate, allowing for precise adaptation to different material densities.
• Automated Cycle Management: Controlled by an integrated electrical system, the machine offers a highly efficient semi-automatic workflow. At the exact end of the cutting cycle, the machine automatically shuts off blade rotation, and the saw frame rapidly returns to its pre-set, adjustable home position, minimizing operator intervention.
• Precision Carbide Blade Guiding: The heavy-duty blade is strictly maintained in a vertical position by a high-precision guide seat structure, utilizing a combination of rolling bearings and hard alloy (tungsten carbide) guide blocks to reduce friction and prolong blade life.
• Customizable Industrial Upgrades: To meet specialized production needs, the H-65/70S can be factory-customized with an automatic hydraulic blade tensioning system, Variable Frequency Drive (VFD) for stepless cutting speed control, and an electric material feeder.
