280x450mm Wide Capacity, Scissor-Type Pivot Frame & Hydraulic Feeding Table
Product Overview
The MFG PX-28/45S is a highly efficient, semi-automatic horizontal metal band saw engineered with a robust scissor-type (pivot) architecture.
Designed for the precision sawing of wider materials—including large mold bases, heavy forgings, wide solid profiles, and hollow tubes—this machine offers excellent adaptability for a broad spectrum of ferrous metals.
Integrating rotary cutting capabilities with a mechanized hydraulic feeding table, the PX-28/45S delivers exceptionally narrow kerfs, substantial material and energy savings, and reliable cutting accuracy.
Its heavy-duty construction and streamlined operational logic make it a highly cost-effective cutting solution for modern fabrication and machining workshops.
Key Features & Engineering Details
- Rigid Scissor-Type Architecture: The saw frame utilizes a bow-shaped, scissor-type (pivot) design. 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. This crucial process eliminates internal welding stresses and minimizes deformation, ensuring lifelong structural stability and precise alignment.
- Hydraulic Material Feeding Table: The premium steel 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 and retracts to realize smooth material feeding and withdrawal, drastically reducing the physical labor required for heavy workpieces.
- 3-Speed Worm Gear Transmission: The main drive system utilizes a high-efficiency main motor, belt pulleys, and a rugged worm gearbox. Through a two-stage speed change mechanism, torque is reliably transferred to the drive wheel, allowing operators to select from three distinct blade speeds to perfectly 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. An additional double-bearing backup structure on the back of the blade further stabilizes the cut.
- Hydraulic Vise with Safety Interlocks: Workpieces are secured using a highly reliable side-down hydraulic vise system (capable of clamping materials as small as 10mm). The independent electrical control cabinet ensures operational safety by integrating a strict interlock system: the saw blade cannot engage unless the main vise is fully clamped.
- Manual Blade Tensioning: A manual tensioning mechanism (comprising a tensioning seat, slider, and lead screw) controls the driven wheel. Operators simply rotate the tensioning handle clockwise to achieve the optimal working tension, preventing blade slippage.
- Independent Hydraulics & Coolant System: A centralized cooling pump continuously delivers emulsion coolant directly to the guide arms, preventing blade overheating, washing away chips, and preventing 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.
