What is a CNC Flame Strips Cutting Machine and How Does It Work?

What is a CNC Flame Strips Cutting Machine?

A CNC flame strips cutting machine is an industrial metal cutting system designed for efficiently dividing steel plates into straight strips using oxy-fuel flame technology. It features a gantry structure with multiple cutting torches arranged along the beam, allowing several strips to be cut simultaneously in a single pass. The YOMI CNC YM-CS model, for example, has an effective working area of 3150×8000mm with a machine footprint of 4000×10000mm, and uses an F2300B CNC control system with Japanese Panasonic servo motors on all axes for precise, stable motion control.

How does a multi-torch strip cutting machine improve cutting efficiency?

A multi-torch strip cutting machine dramatically improves efficiency by mounting multiple flame cutting torches on the gantry beam simultaneously. Instead of cutting one strip at a time, the machine can cut N strips in a single pass — typically, if you need N straight strips, you equip N+1 cutting torches. The YOMI CNC flame strips cutting machine uses a front group of longitudinal torches for straight cuts and a rear set of lateral torches for transverse cuts, so the machine can divide a large steel plate into multiple strips and parts in one traverse. This bilateral-drive gantry design ensures consistent cutting quality across the full width, while the number of torches can be configured according to user needs.

What materials and thicknesses can a CNC flame cutting machine cut?

CNC flame cutting machines are primarily designed for cutting carbon steel (mild steel), low-alloy steel, and other ferrous metals. Flame cutting excels at thick plate processing, typically handling thicknesses from 6mm up to 150mm or even 300mm with high-capacity torches. The YOMI CNC flame strips cutting machine is mainly used for cutting mild steel and steel alloy plates, and it is widely applied in boiler manufacturing, chemical industry, pressure vessel production, power stations, metallurgical engineering, and structural steel fabrication. It is important to note that flame cutting cannot cut stainless steel, aluminum, or other non-ferrous metals — for those materials, a plasma cutting option can be added.

Flame cutting vs plasma cutting — which is better for strip cutting?

The choice between flame and plasma cutting depends on material thickness and type. Flame cutting is the superior choice for thick carbon steel plates (above 25mm), offering lower equipment cost, simplicity, and portability. It produces a wider kerf (1.5-3mm) and rougher edges but handles very thick steel efficiently. Plasma cutting is faster on thin to medium materials (up to 25mm), produces cleaner cuts with narrower kerf, and can cut stainless steel and aluminum. The YOMI CNC flame strips cutting machine supports both flame and plasma cutting methods, so you can choose the appropriate method based on your material type and thickness — flame for thick carbon steel strips, plasma for thinner plates or non-ferrous metals.

Can a CNC flame cutting machine be upgraded to include plasma cutting?

Yes, many CNC flame cutting machines can be equipped with a plasma cutting option, enabling both flame and plasma CNC cutting capabilities in a single machine. The YOMI CNC flame strips cutting machine supports both flame and plasma cutting methods, giving fabricators the flexibility to switch between methods depending on material type and thickness. This dual-capability design is especially valuable for steel structure workshops that handle a variety of plate materials — flame for thick carbon steel and plasma for thinner plates or special metals — without needing two separate machines.

What CNC control system and software does the YOMI flame strips cutting machine use?

The YOMI CNC flame strips cutting machine is equipped with the F2300B CNC control system, a two-axis digital controller developed by Shanghai Jiaotong University, known for its high integration, stability, and user-friendly interface. It uses StartCAM nesting software for automatic programming and nesting, which allows operators to easily load DXF graphics or create designs using the integrated CAD system. The software automatically generates the optimal cutting path, which can be adjusted at any time. All three axes (X, Y, Z) are driven by Japanese Panasonic servo motors — 750W on X and Y axes with reducers, and 400W on the Z axis — ensuring high transmission accuracy, longer service life, and lower failure rates.

What is the cost of a CNC flame strips cutting machine?

The cost of a CNC flame cutting machine varies based on cutting area size, number of torches, control system, and whether plasma capability is included. Entry-level handheld oxy-fuel torches start as low as $200-$500, while industrial-grade CNC flame cutting tables typically range from $15,000 to over $100,000 depending on size and automation level. The YOMI CNC flame strips cutting machine, with its 3150×8000mm working area, multi-torch configuration, F2300B control system, and Panasonic servo motors, offers excellent value for steel structure fabrication shops.

How to maintain and troubleshoot a CNC flame cutting machine?

Regular maintenance of a CNC flame cutting machine includes: checking oxygen and fuel gas pressures to ensure they are within the recommended range; inspecting and cleaning cutting torch nozzles to prevent blockages that cause slow cutting or poor quality; verifying the flame is properly adjusted (a blue, stable flame indicates correct gas mixture); checking the gear rack and guide rail for wear and proper lubrication; and ensuring the electrical system connections are secure. Common issues include slow cutting speed (often caused by low gas pressure or blocked nozzles), poor cut quality (incorrect torch height or gas ratio), and unstable flame (imbalanced oxygen-to-fuel ratio). The YOMI CNC machine features automatic electronic ignition and a capacitor height controller to maintain optimal torch-to-plate distance, reducing nozzle wear and improving cutting consistency.
