Model: CF-1300DMS Heavy-Duty Double Column Semi-Automatic Double Miter Bandsaw
Key Components & System Configuration
- Heavy Cutting Capacity — Cuts Ø600 mm (Ø23.6 in.) round pipes, large H-beams, structural channels, and bundled hollow sections.
- Wide Dual-Direction Mitering — Robust saw frame swivels bi-directionally from +60° to -45° without moving the workpiece.
- Hydraulic Top Clamp Bundle Fixture — Heavy vertical clamping assembly firmly secures bundled pipes to prevent scattering and vibration.
- Dual-Vise Clamping System — Provides rigid work holding both before and after the blade cut-line for maximum cut squareness.
- Hydraulic Blade Tension Control — Maintains constant optimum tension across the blade to ensure straight cuts and prolong blade life.
- Precision Laser Alignment Guide — Projects an accurate physical cut-line indicator for rapid optical setup and positioning.
- Hydraulic Spray Mist Lubrication System — Eco-friendly near-dry mist lubrication delivering superior chip evacuation and clean, dry cuts.
- Proportional Vice Pressure Regulation — Adjustable clamping pressure protects thin-walled pipes and tubes from crushing.
- 12 m (39.4 ft) Motor-Driven Infeed Table — Heavy-duty powered rollers advance long, bulky steel beams smoothly.
- 6 m (19.7 ft) Motor-Driven Outfeed Table — Automatically evacuates severed workpieces from the cutting envelope.
- 6 m (19.7 ft) Automated Length Stopper — Delivers rapid and repeatable length indexing without manual tape measuring.
- Auxiliary Transition Side Clamps — Heavy guide vices installed between infeed rollers maintain alignment on long bundled stock.
