CNC round pipe cutting machine with plasma LAZIRON XY5

A CNC round pipe cutting machine is the solution for shops that make intersections, saddle joints and weld bevels on pipe every day and still mark them out with a template. LAZIRON XY5 is a specialised CNC machine for automatic cutting of metal pipes with plasma or an oxy-fuel flame, on round pipes of 60–630 mm or 60–800 mm and on lengths of 6–12 m, which can be customised. The machine programs automatically and performs automatic CNC nesting for any type of complicated joint between pipes, and any type of weld bevel is cut in a single pass.

In the production flow, the XY5 sits between the pipe store and the welding station. It replaces unfolding on paper, the template wrapped around the pipe, manual torch cutting and grinding until the joint closes. The pipe comes out cut, with the intersection contour and the weld preparation formed, with an accuracy of ±1.5 mm. See also the other machines in the CNC large pipe cutting category.

Because it works only with round pipe, the XY5 is a machine focused on a single type of part, with a simple, horizontal construction that is easy to maintain. If your production is mostly round pipe, a dedicated CNC round pipe cutting machine gives you everything you need, without paying for capabilities you do not use.

Advantages of the plasma cutting machine for round pipe

• Precise intersections: accurate intersection cuts on round pipes, for correct joints and less finishing work. The welder receives the part ready for tacking, without adjustments with the grinder.

• Automatic programming and nesting: the machine generates the program on its own and performs CNC nesting for any type of complicated joint between pipes, so you do not depend on a programmer for every new part.

• Any bevel in a single pass: the weld preparation is formed in the same cut as the contour, without a separate chamfering operation.

• Varied cuts: bevels, saddle cuts and cuts at complex angles, for different project requirements and different materials.

• Plasma and oxy-fuel: bevelling of up to ±45° with plasma and up to ±55° with a flame. You choose the process according to wall thickness and the joint required by the welding procedure.

• Servo motor drive: travel is driven by Panasonic servo motors (Japan), with a travel speed of 10–6000 mm/min and a cutting speed of 10–2000 mm/min.

• Automatic operation: the CNC control automates cutting, optimises paths, reduces errors and increases efficiency, which makes it suitable for high-volume production.

• Long pipes: the cutting length of 6–12 m, customisable, covers standard pipe bars without intermediate cuts.

How the XY5 machine is built

The machine has a horizontal structure, and each component has a clear role in the stability and accuracy of the cut:

• Bed: a welded frame made of square tube, which takes the weight of the pipe and the vibrations during work.

• Pipe rotation mechanism: a three-jaw chuck and a Y-axis drive unit, for smooth rotation of the pipe during cutting.

• Pipe supports: four scissor-type supports, which hold the pipe and keep it stable during work.

• Torch travel mechanism: precise positioning of the cutting head along the pipe.

• Torch lifting mechanism: the height adjustment needed during cutting.

• Torch tilting mechanism: made of CNC-machined aerospace-grade aluminium, for accuracy and durability when bevelling.

• Track: high-precision 24 kg guide rails, which transmit the movement of the carriage and ensure smooth travel.

• Electrical control system: integrates all components for efficient operation.

This construction has a practical advantage for maintenance: the mechanisms are separate and easy to access, and a plasma cutting machine for pipe built on a welded bed and 24 kg guide rails keeps its alignment over time. At commissioning, our team checks every mechanism and shows the operators the daily maintenance points, so that the ±1.5 mm accuracy stays the same even after years of work.

Applications: pipe cutting for pipelines, construction and large diameter pipe

In pipeline fabrication, every branch and every nozzle means an intersection between two pipes, with a weld preparation along the whole contour. A CNC round pipe cutting machine cuts both the profiled end of the branch and the hole in the main pipe, with the bevel required by the welding procedure. On a large diameter pipe, up to 800 mm, the time saved compared with manual marking out is all the greater the longer the contour is.

In construction, the XY5 prepares pipes for tubular structures: trusses, columns, canopies and space frames, where pipes are joined at different angles. Saddle joints and cuts at complex angles come directly off the machine, and erection goes faster because the parts fit first time. For shops that do pipe cutting to order, the machine widens the range of jobs they can accept with intersections they would otherwise turn down.

When the wall is thick or the procedure calls for a large bevel, oxy-fuel cutting with bevelling of up to ±55° complements plasma cutting, which remains the right choice for speed on thinner walls. The machine uses CE-certified components, in line with the requirements of the Machinery Directive 2006/42/EC.

If you also work with square or rectangular pipe, compare it with the XF8 8-axis CNC machine for round and square pipe. For even larger diameters, see the cutting machine for large diameter pipes.

What changes in the shop

In a shop that works by hand, a good intersection depends on an experienced marker, and these people are increasingly hard to find. Every joint needs time for unfolding, marking out and adjusting, and the result varies from one person to another. With the XY5, the geometry knowledge is in the program: the operator chooses the joint type, clamps the pipe and starts the cycle.

The effect shows in welding. When joint gaps are uniform along the whole contour, the welder works faster, uses less filler material and has fewer defects to repair. On large pipe batches, the same geometry is repeated identically, and quality control becomes a check, not a correction.

How the XY5 machine works

The flow on a CNC round pipe cutting machine is short and repeatable, from the geometry of the joint to the part ready for welding:

1. Defining the joint: you enter the type of joint between the pipes, and the machine automatically programs the contour and performs CNC nesting.

2. Loading the pipe: the pipe is clamped in the three-jaw chuck and rests on the four scissor-type supports, over a length of 6–12 m.

3. Choosing the process: plasma, with bevelling of up to ±45°, or oxy-fuel, with bevelling of up to ±55°, according to wall thickness.

4. Cutting: the pipe rotates smoothly, and the torch travels, lifts and tilts to follow the contour, at cutting speeds of 10–2000 mm/min.

5. Unloading: the part comes out with the intersection contour and the weld preparation finished, with an accuracy of ±1.5 mm.

Operator training is included at commissioning and covers this whole cycle, so your team can work on its own from the very first orders. For recurring orders, the same joint is repeated without new setups, and the result does not depend on the operator on shift.
