MFG H-50/70S Semi-Automatic Horizontal Band Saw

Heavy-Duty Double-Column Architecture, Stepless Hydraulic Feed & Automated Cycle Return

Product Overview

The MFG H-50/70S is a heavy-duty, semi-automatic horizontal band saw engineered for high-capacity industrial metal fabrication.

Designed to process large metal profiles, heavy solid tubes, steel billets, and mold blanks, this machine is an essential high-efficiency cutting solution for the metallurgy, mining, petroleum, shipbuilding, and heavy machinery industries.

Built upon a robust main and sub-column horizontal structure, it utilizes a narrow-kerf bi-metal band saw blade to maximize material savings and reduce power consumption. With advanced hydraulic controls and automated cycle management, the H-50/70S ensures exceptional cutting precision and reliability for large-scale workpiece processing.

Key Features & Engineering Details

• Rigid Double-Column Architecture: The saw frame is supported by a heavy-duty main column and a secondary sub-column. This highly stable horizontal structure guarantees absolute rigidity and ensures sufficient load-bearing margins, eliminating vibration during the sawing of large, heavy billets.
• Centralized Hydraulic System & Clamping: The machine features a comprehensive hydraulic circuit (tank, motor pump, relief valve, and solenoid directional valves). 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 and cross-sections.
• Automated Cycle Management: Controlled by an integrated electrical system, the machine offers a highly efficient semi-automatic workflow. At the end of the cutting cycle, the machine automatically shuts off the blade and the saw frame rapidly returns to its pre-set, adjustable home position, minimizing idle time between cuts.
• Precision Carbide Blade Guiding: The bi-metal band saw 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. This dramatically reduces friction and significantly prolongs blade life.
• Customizable Industrial Upgrades: To meet highly specialized production needs, the H-50/70S 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.
