MFG H-33/40S Semi-Automatic Horizontal Band Saw

Double-Column Architecture, 5-Speed Regulation & Precision Worm Gear Drive

Product Overview
The MFG H-33/40S is a heavy-duty, semi-automatic horizontal band saw engineered for high-efficiency metal cutting in medium to large industrial enterprises. Designed to process steel billets, profiles, and a wide variety of soft and hard ferrous and non-ferrous metals, it offers a robust cutting capacity of up to 330mm in height and 600mm in width.

Manufactured under rigorous quality control standards, the machine features a vibration-aged structural frame, a hard-chrome-plated double-column guiding system, and a 5-level speed regulation drive. It delivers reliable cutting precision, reduced blade breakage, and excellent long-term durability for demanding fabrication environments.

Key Features & Engineering Details

• VSR-Treated Heavy Structure: The main structural components, including the machine bed and saw frame, undergo rigorous surface sandblasting and Vibration Stress Relief (VSR) aging. This specialized process effectively eliminates internal welding stresses and increases surface paint adhesion for long-lasting rust protection.
• Precision Double-Column Design: The saw frame is guided by an asymmetrical double-column structure (one large, one small). The column surfaces are coated with hard chrome to provide exceptional wear resistance, rust prevention, and highly precise lifting movement.
• Precision Ground Worm Gear Drive: The main transmission utilizes a high-efficiency motor paired with a rigorously processed worm gear. The gear manufacturing process includes material removal, rough machining, quenching, finishing, surface quenching, and final tooth grinding, ensuring exceptionally smooth and reliable torque transfer.
• 5-Level Speed Regulation: Operators can easily select between five distinct blade speeds via a reliable belt speed regulation system, allowing for optimal cutting conditions based on different material hardness levels and prolonging blade life.
• Hydraulic & Manual Clamping: Workpiece clamping utilizes a highly reliable combination of hydraulic pressure and manual adjustment, ensuring secure material holding while remaining labor-saving and easy to operate.
• Tungsten Carbide Blade Guiding: The heavy-duty 34x1.1mm band saw blade is strictly guided by a combination of bearings and adjustable tungsten steel (carbide) inserts. The 34mm blade width enhances the sawing ability for high-hardness alloys and significantly reduces the risk of blade breakage.
• Premium Electrical & Hydraulic Systems: The electrical cabinet is built using original devices from the Chint Group. The main hydraulic system utilizes high-quality domestic seals and components, ensuring a long, trouble-free service life.
• Integrated Blade Maintenance: Equipped with a flexible steel wire brush that continuously clears iron chips from the saw band teeth, effectively preventing chip accumulation and prolonging the cutting life of the blade.
• Customizable Material Feeding: The machine can be optionally equipped with electric or passive material feed frames, with lengths and quantities fully customizable based on specific shop floor requirements.
