MFG H1-50/65S Semi-Automatic Horizontal Band Saw

Dual 140mm Cylindrical Columns, 3-Speed Worm Gear Drive & Automated Cycle Return

Product Overview

The MFG H1-50/65S is a highly robust, semi-automatic horizontal straight-cutting band saw engineered for heavy-duty industrial metal fabrication.

Designed to efficiently process large metal profiles, solid tubes, heavy steel billets, and mold blanks, this machine is an indispensable cutting solution for metallurgy, mining, automotive, and heavy machinery manufacturing.

Built upon an exceptionally rigid dual-column structure featuring oversized 140mm cylindrical columns, it ensures absolute cutting stability.

Combined with a 3-speed worm gear transmission, stepless hydraulic feed, and precision tungsten carbide guides, the H1-50/65S delivers superior cutting accuracy, reduced material waste, and highly efficient batch production capabilities.

Key Features & Engineering Details

• Oversized Dual 140mm Column Architecture: The vertical lifting movement of the saw frame is guided by two massive 140mm cylindrical columns equipped with precision guiding sleeves. This specialized, heavy-duty structural design ensures absolute rigidity, perfectly absorbing vibrations and guaranteeing superior accuracy when cutting large-diameter billets.
• Stress-Relieved Machine Bed & Frame: The machine's foundation and saw frame are constructed from premium welded steel plates. These critical components undergo a strict post-weld aging (stress-relief) treatment to eliminate internal structural stresses, providing exceptional long-term geometric precision.
• 3-Speed Worm Gear Transmission: The main drive system consists of a high-torque main motor and a heavy-duty worm gearbox. By simply adjusting the V-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 circuit, 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 material's cross-section and density.
• Heavy-Duty Hydraulic Clamping: Workpieces are secured on a flat, smooth workbench by a powerful hydraulic vise. The movable jaw is propelled by a dedicated hydraulic cylinder along a precision slide groove, completely immobilizing large materials during high-torque cutting.
• Automated Cycle Management: The integrated electrical and hydraulic systems provide a highly efficient semi-automatic workflow. At the end of the cutting cycle, the machine automatically shuts off the blade rotation, and the saw frame rapidly returns to its adjustable home position, minimizing operator intervention.
• Precision Carbide Blade Guiding: The bi-metal band saw blade is maintained in a strict vertical orientation by a combination of heavy-duty rolling bearings and tungsten steel alloy (carbide) inserts. This drastically minimizes friction and extends blade life.
• Integrated Cooling & Chip Sweeping: The welded machine bed features a built-in coolant pool for continuous blade lubrication and heat dissipation. A mechanical wire brush sweeping device continuously removes chip accumulation from the blade teeth, protecting the saw band.
