The LX-K73 Heavy Duty Tube Laser Cutting Machine by LONX LASER is a robust, high-precision industrial laser pipe processing system specifically engineered for massive structural steel, large-diameter pipes, and heavy profiles
Designed to replace traditional sawing, drilling, and manual plasma cutting, the LX-K73 integrates a 730mm full-stroke pneumatic chuck system, 33-ton heavy-duty annealed machine bed, and intelligent follow-up support mechanism
Extra-Large Processing Range: Cuts round tubes up to Φ710mm and square tubes up to 500x500mm
Massive Payload Capacity: Supports individual pipe weights up to 4,000 kg (<=333 kg/m)
Ultra-Short Tailing (Zero-Tailing): Advanced chuck avoidance mechanism ensures zero tailing under applicable conditions, maximizing raw material utilization
Versatile Profile Processing: Easily cuts H-beams, I-beams, channel steel, angle steel, and custom structural profiles
Steel Structure & Tower Construction: Precision processing of heavy structural columns, trusses, and beam connection holes
Shipbuilding & Marine Engineering: High-efficiency thick-walled marine pipe cutting
Bridge Engineering & Infrastructure: Heavy profile cutting with structural integrity
Petroleum Pipelines & Engineering Machinery: Precision pipe cutting for oil rigs and heavy machinery frames
Materials: Carbon steel, stainless steel, aluminum alloy, copper, and special steel alloys
Profiles Supported: Round tubes, square tubes, rectangular tubes, Channel Steel (10#-40#), Angle Steel (50x50-250x250mm), I-Beam (10#-45#), and H-Beam (HW, HM, HN series)
Annealed Machine Bed Frame: Welded from premium steel plates and subjected to high-temperature annealing and precision gantry milling, guaranteeing zero structural deformation over decades of high-intensity operations
730mm Full-Stroke Pneumatic Chuck: Features a rail-driven four-jaw mechanism providing up to 25 rpm rotational speed and 0.05 mm repeat accuracy, holding heavy 4000 kg pipes securely
Multi-Point Follow-Up Support System: Dynamically adjusts support height according to pipe rotation to minimize sag and ensure cutting consistency on 12m long heavy pipes
BOCHU Intelligent CNC & Nesting System: Supports automatic edge finding, four-sided tube centering, weld seam avoidance, leapfrog cutting, and rapid profile file conversion (IGS/STEP)
