The laser-flame composite cutting machine integrates the advantages of laser cutting and flame cutting technologies to realize high-efficiency and high-precision thick plate processing. Its core working principles and functional features are summarized as follows:
Working Principle
Energy Synergy Mechanism
The machine adopts a coaxial integrated cutting head design, with fully overlapping laser beam and flame injection paths. High-density laser energy first creates pre-piercing holes on the material surface, which greatly improves the thermal efficiency of flame cutting and shortens piercing time. It takes only 10 seconds to pierce 120 mm carbon steel plates. During the cutting process, the laser continuously heats the material edge, while the flame provides additional thermal energy through oxidation reactions. The synergistic effect of the two heat sources enables rapid material melting and separation.
Dynamic Process Switching
The system automatically adjusts the power ratio of laser and flame according to different material thicknesses. For steel plates ranging from 50 mm to 120 mm, the laser is responsible for piercing and precise contour cutting, while the flame accelerates the main kerf cutting process. For ultra-thick plates above 120 mm, the machine automatically switches to pure flame cutting mode.
Core Functional Features
High Efficiency & Energy Saving
Compared with traditional high-power laser cutting machines, its energy consumption is reduced by more than 70%. A 3000-watt unit can achieve the cutting performance equivalent to a 60000-watt laser machine. The thick plate cutting efficiency is increased by 50%, with a maximum cutting capacity of 200 mm carbon steel.
High-Precision Machining Performance
Verticality Control: The single-side verticality error of 100 mm steel plates is controlled within 0.2 mm (20 wire gauge).
Small Hole Machining: It can stably cut 20 mm diameter holes on 55 mm steel plates and support mass production of 30 mm small holes on 100 mm steel plates.
Taper Optimization: Laser preheating optimizes the section quality of flame cutting and eliminates taper defects commonly found in conventional flame cutting.
Intelligent Adaptation System
Equipped with a large Chinese touch screen, the machine supports personalized parameter customization for power, track gauge, track length and more. It is compatible with various design software to realize intelligent production. The automatic positioning and width adjustment functions meet the cutting requirements of straight lines, arcs and special-shaped workpieces.
This equipment is specially tailored for thick plate processing industries such as steel structure manufacturing and construction machinery. Through integrated compound technology, it solves the pain points of slow piercing and low precision of pure flame cutting, while compensating for the high energy consumption and poor section quality of single laser cutting in thick plate processing.
