MFG PX-28/34S Semi-Automatic Scissor-Type Rotary Metal Band Saw

Scissor-Type Pivot Architecture, Hydraulic Feeding Table & 3-Speed Worm Gear Drive

Product Overview
The MFG PX-28/34S is a highly efficient, semi-automatic horizontal metal band saw featuring a reliable scissor-type (pivot) structure. Engineered for the precision sawing of large mold materials, heavy forgings, solid profiles, and hollow tubes, this versatile machine is highly adaptable for a wide range of ferrous metals. Integrating rotary cutting capabilities with a hydraulic feeding table, the PX-28/34S delivers narrow kerfs, substantial material and energy savings, and exceptional cutting accuracy. Its rigid construction and streamlined operation make it an ideal, cost-effective cutting solution for modern fabrication and machining facilities.

Key Features & Engineering Details

• Rigid Scissor-Type Architecture: The saw frame utilizes a bow-shaped, scissor-type (pivot) structure. Welded from high-quality steel plates with reinforced ribbing, both the saw frame and the box-structure base undergo rigorous Vibration Stress Relief (VSR) treatments to eliminate internal welding stresses and minimize deformation, ensuring lifelong structural stability.
• Hydraulic Material Feeding Table: The worktable is equipped with 4 integrated guide rollers and operates on base-mounted guide rails. Driven by a dedicated hydraulic cylinder, the table automatically pushes forward to realize smooth material feeding and withdrawing, greatly reducing operator physical strain.
• 3-Speed Worm Gear Transmission: The main drive system utilizes a main motor, belt pulleys, and a high-efficiency worm gear box. Through a two-stage speed change mechanism, torque is transferred to the drive wheel, allowing operators to select from three distinct blade speeds to match different metal hardness levels.
• Precision Blade Guiding: The guiding device features movable left and right guide arms mounted on a dovetail crossbeam. To reduce vibration and ensure the blade remains perfectly perpendicular to the table, the arms utilize a combination of rolling bearings and wear-resistant guide blocks. A double-bearing back-up structure further stabilizes the blade during heavy cuts.
• Hydraulic Vise with Safety Interlocks: Workpieces are secured using a highly reliable hydraulic vise system (capable of clamping materials as small as 10mm). The independent electrical control cabinet ensures maximum operational safety by integrating an interlock system: the saw cannot initiate a cut unless the main vise is securely clamped.
• Manual Blade Tensioning: A manual tensioning mechanism (consisting of a tensioning seat, slider, and lead screw) controls the driven wheel. Operators simply rotate the tensioning handle clockwise to reach the optimal working tension, ensuring sufficient friction between the blade and the wheel rim.
• Independent Hydraulics & Coolant System: The machine features a centralized cooling pump that continuously delivers emulsion coolant directly to the guide arms, preventing blade overheating and surface rust. The hydraulic system is powered by an independent station utilizing premium domestic pumps and solenoid valves for reliable lifting, clamping, and feeding operations.
