Overview & Automated HVAC Air Duct Cutting

The CNC Plasma Cutting Machine for HVAC Sheet Metal Air Ducts (Model: JL-1500×4000) is an industrial high-speed CNC plasma cutting solution engineered specifically for ventilation duct manufacturers, industrial dust extraction contractors, and architectural sheet metal fabricators[cite: 116]. It replaces traditional manual layout, shearing, and nibbling with fully automated CNC profiling[cite: 116].

Driven by a proven Beijing Starfire CNC control platform and integrated with specialized CAM-DUCT software, the system enables operators to select standard fittings (rectangular ducts, round elbows, transitions, tees, and boots), input basic dimensions, and execute high-speed nesting and clean plasma severance automatically[cite: 116, 120].

Precision Motion Control & Mechanical Hardware

• Heavy-Duty Welded Tubular Bed: Thick-walled steel tubes are integrally welded and stress-relieved to ensure long-term mechanical stability, vibration dampening, and high durability under heavy production cycles[cite: 116].
• Dual-Drive Rack & Linear Guides: High-precision dual-side rack-and-pinion transmission combined with linear guideways delivers positioning accuracy and traverse speeds exceeding 12,000 mm/min[cite: 116].
• Chengdu Huayuan 63A Plasma Power: Stable constant-current plasma generator produces high arc density, small kerf width, and virtually dross-free edges on plates from 0.5 mm to 5.0 mm[cite: 116].
• Pneumatic Torch Height Regulation: Responsive pneumatic height sensor automatically adjusts torch distance in real time, preventing collision with wavy thin galvanized sheets[cite: 116].
