MFG H1-40/50S Semi-Automatic Horizontal Band Saw

Extra-Wide Double-Column Architecture, 3-Speed Worm Gear Drive & Stepless Hydraulic Feed

Product Overview
The MFG H1-40/50S is a heavy-duty, semi-automatic horizontal band saw engineered specifically to accommodate extra-wide metal workpieces.

Designed to efficiently process massive steel billets, large mold blanks, and wide structural profiles, it is an indispensable cutting solution for the metallurgy, petroleum, automotive, and shipbuilding industries.

Built upon a highly rigid double-column structure and a stress-relieved welded steel bed, the machine utilizes a bi-metal band saw blade to deliver a narrow kerf and maximize material savings.

With its 3-speed worm gear transmission and infinitely adjustable hydraulic feed, the H1-40/50S ensures precision, stability, and high performance for the most demanding wide-capacity applications.

Key Features & Engineering Details

• Rigid Double-Column Architecture: The saw frame's vertical lifting movement is guided by a heavy-duty cylindrical main column and supported by a square sub-column equipped with a precision guiding sleeve. This asymmetrical double-column design ensures absolute structural reliability and prevents lateral deflection when cutting extra-wide materials.
• Stress-Relieved Steel Bed & Frame: The machine's foundation (bed foot) and saw frame are constructed from premium welded steel plates. Crucially, these components undergo a strict post-weld aging treatment to eliminate internal stresses, providing exceptional rigidity and vibration absorption.
• 3-Speed Worm Gear Transmission: The main drive system utilizes a high-torque main motor paired with a robust worm gear box. By adjusting the belt on the pulley system, operators can easily switch between three distinct cutting speeds, optimizing the blade RPM for varying ferrous and non-ferrous material hardness levels.
• Stepless Hydraulic Feed Regulation: Powered by a centralized hydraulic station, the downward feed rate of the saw frame can be regulated steplessly via a highly responsive speed control valve. This allows operators to perfectly match the cutting feed to the cross-section of large billets.
• Heavy-Duty Hydraulic Clamping: Workpieces are placed on a smooth, flat workbench and clamped securely by a heavy-duty hydraulic vise. The movable left jaw is propelled by a hydraulic cylinder along a precision slide groove, completely immobilizing wide plates and billets during high-torque cutting.
• Tungsten Carbide Blade Guiding: The bi-metal blade is maintained in a strict vertical orientation by a combination of heavy-duty bearings and tungsten steel alloy (carbide) inserts. The guide arm can be manually locked on the crossbeam to achieve the shortest possible distance to the workpiece, maximizing blade rigidity.
• Integrated Cooling & Chip Sweeping: The plate-welded bed features a built-in coolant pool for continuous blade lubrication. A mechanical wire brush sweeping device automatically removes chip accumulation from the blade teeth, significantly extending the band saw's service life.
