The Longmen CNC Tube Plate Integrated Cutting Machine is a versatile solution that combines plate cutting and circular pipe intersection line cutting. This dual functionality means one machine can handle both tasks, significantly reducing equipment investment for businesses. The gantry beam is constructed from welded thick profiles and undergoes aging treatment, ensuring excellent stability and adjustable running speeds. Its CNC cutting system features user-friendly software that imports DXF files, enabling intricate cuts like round holes, irregular shapes, and pipe intersections. Plates are cut using flame plasma, while rotating fixtures precisely position pipes for hole cutting and beveling. The machine is easy to operate, with a low learning curve for new users after basic training. Its cutting area is customizable to fit various production environments and is ideal for steel structure, pipeline engineering, and pressure vessel manufacturing. With a low failure rate and simple maintenance, it's an economical cutting choice for small to medium metal processing operations.
The capacitive sensing is sensitive enough to detect a 0.2mm variance in plate flatness. This is critical when you are cutting thick mild steel. The reduced sensitivity to plate warping means no "crashing" into the workpiece.
The design supports long, uninterrupted runs. The heavy-duty motor on the X-axis doesn't overheat even when running continuous cutting cycles.
With the SMC proportional valve, you get precise control over the gas mixture. This is vital for achieving a square cut edge, which reduces the need for downstream bevelling
We provide the FLCAME software. It helps you figure out the most economical way to arrange your parts on a single steel sheet, minimizing the gap between shapes and reducing scrap metal.
We build our crossbeam from thick, welded, high-strength structural steel. But the key difference is the stress-relief process. We place the welded frame into a furnace to slowly heat and cool it. This aligns the grain structure of the steel and eliminates residual stresses. After machining, the guide rails stay perfectly parallel. We've seen machines from other factories where the rails were machined before the stress relief, and they warped within 6 months of usage. We avoid that by doing the annealing before precision milling.
For the transmission, we stick to industrial-grade precision racks. Why not ball screws? For a 5-meter travel, a ball screw would sag in the middle. A rack system keeps the drive force consistent across the whole length, ensuring that the cutting speed remains constant regardless of where the torch is positioned on the bed.
Mr. Wang set up a small metal processing workshop, which not only cuts steel plates but also undertakes the processing of pipe intersections. Previously, he purchased two separate pieces of equipment, but the space was insufficient and the pressure of equipment investment was very high. By chance, he learned about the Jieliang Pipe Plate Integrated龙门 CNC Cutting Machine, which can perform both plate and pipe processing with one machine. He immediately made up his mind to purchase it.
After the equipment was installed, it solved the biggest problem of the workshop. For plate processing, it uses plasma flame cutting, and with rotating fixtures, it can cut pipes. Making holes, making bevels, and cutting are all within reach. The CNC system is easy to operate and does not require professional programmers. Ordinary workers can learn to operate it independently in a few days. The machine runs stably, has a low failure rate, and the daily maintenance is simple. Many pipe fittings orders that were previously too risky to accept can now be successfully won. Without increasing the factory area, new business has been expanded. The orders are increasing, and the investment in the equipment soon shows returns. The small factory has gradually opened the local market.
Standard Technical Specifications
The SG gantry CNC cutting machines come with a choice of 1500W, 2000W, or 3000W laser generators from reputable brands like Chuangxin and Ruike. They feature the Fangling L5210H control system and FLCAME layout software for easy and efficient design work. The laser cutting head is an Ouspuri LCN03A/LCS03C, and they include Tero/Hanli water chillers as standard. For movement, the Z-axis uses a servo drive, while the X and Y axes use stepper motors. Key components like the drive system and X/Y axes are from Leisa and Statt. Jiuming provides the custom crossbeam guide rails, and SMC handles the proportional valves. Electrical parts are sourced from ZTE and Delixi. Optional additions include a 30KW Mengkun voltage stabilizer and a 15KW 16kg Yinglei screw air compressor. All components are chosen for reliability, ensuring smooth operation for extended factory laser cutting tasks.

Q1: How does this machine handle cutting with excessive slag?
Slag build-up happens when the travel speed is too slow or the amperage is too high. Our built-in speed override allows your operator to tweak the feed rate in real-time while watching the first cut. Once they dial in the perfect speed for that specific plate thickness, the machine saves that profile, so the next sheet cuts perfectly with no dross.
Q2: What is the main factor that affects the cutting speed?
It is strictly the thickness and the amperage of the plasma source. For 12mm mild steel, with a 100A power source, you can expect a travel speed of around 2500mm/min. For 25mm steel, you drop down to roughly 800mm/min. The physical gantry structure is designed to handle speeds far higher than this, so the machine's frame is never the bottleneck.
Q3: Can I cut aluminum and stainless steel with this?
Yes, but you must swap the plasma gas. For mild steel, we typically use compressed air. For aluminum or stainless steel, we recommend switching to nitrogen or argon-hydrogen mixtures to achieve a cleaner edge and reduce oxidation. We'll include the gas connection diagram in the manual.
Q4: How does a voltage stabilizer protect the machine?
The CNC controller and the plasma power supply rely on stable 380V 3-phase power. If the voltage drops below 340V, the power supply may trip off mid-cut, ruining your part. A 30KW stabilizer handles these dips automatically, keeping your cutting process running smoothly even when the local power grid fluctuates.
Q5: Do I need a dedicated operator to manage the nesting software?
The nesting software (FLCAME) is user-friendly. Most mechanical technicians can learn to load and arrange files in two to three days. For the most complex nesting patterns, our support team can run a sample layout for you and send the file back, so you just load it and go.
