LAZIRON T4 Four-Chuck Tube Laser Machine

The four-chuck tube laser machine LAZIRON is the LAZIRON flagship for cutting heavy industrial tubes and profiles. The 4-chuck system, two main plus two dynamic intermediate, eliminates any axial deviation or torsion, guaranteeing absolute precision on very long profiles with thick walls.

With a fiber laser source between 3 and 12 kW, tube processing capacity up to Ø500 mm and lengths of 12000-16000 mm, every LAZIRON T4 four-chuck tube laser machine is built for industries that work with heavy structural profiles: the offshore industry, shipbuilding, heavy machinery plants and manufacturers of metal bridge structures.

What makes the LAZIRON T4 a four-chuck tube laser machine built for real production

The LAZIRON T4 four-chuck tube laser machine combines in a single system the advantages that matter on the tube production line: repeatable precision, parameter automation, predictable operating costs and a long service life for critical components.

• System with 4 synchronized chucks — two fixed main plus two dynamic intermediate that move synchronized with the head, completely eliminating deviation on very long profiles with thick walls.
• Fiber laser power 3–12 kW — required for cutting heavy structural profiles with walls above 8 mm, at commercial speeds for industrial batches.
• Tube capacity Ø60–Ø500 mm — covers the entire range of profiles for the offshore, naval, heavy machinery and metal bridge structure industries.
• Maximum length 16000 mm — allows cutting standard long profiles for the offshore industry and naval structures without intermediate welded joints.
• Dynamic intermediate chucks — move automatically and synchronized on rails parallel to the tube axis, keeping the support permanently in the optimal cutting zone.
• RayTools head with capacitive autofocus — automatic compensation for dimensional variations, essential for heavy profiles where deviations from nominal are frequent.
• Cypcut software with tube heavy module — includes thermal compensation on thick walls, automatic parameter calculation for profiles over 10 mm and direct import from 3D CAD models.

Technical specifications — LAZIRON T4 four-chuck tube laser machine

This LAZIRON four-chuck tube laser machine is available in standardized configurations, the choice being made according to the mix of tubes processed and the workshop's monthly production volume.

Industries that use a LAZIRON four-chuck tube laser machine

A LAZIRON four-chuck tube laser machine is built for the most demanding industries, where heavy structural profiles, perfect edge quality and monoblock part cutting are non-negotiable criteria.

The offshore industry (oil platforms, structures for offshore wind turbines) and shipyards use a single LAZIRON T4 four-chuck tube laser machine to cut structural profiles of 300×300 mm with walls of 12-20 mm and lengths of 14-16 m, eliminating intermediate welded joints that would affect mechanical integrity under cyclic loads.

Heavy machinery plants (excavators, mobile cranes, mining equipment), manufacturers of metal bridge structures and energy equipment factories (components for onshore wind turbines) justify the investment in the four-chuck tube laser machine through payback in 24-36 months at the typical volumes of 200-500 heavy profiles/month. Reducing the consumption of welding electrodes and skilled labor brings additional savings.

Materials compatible with a LAZIRON four-chuck tube laser machine

With fiber laser sources between 3 and 12 kW, every LAZIRON LAZIRON T4 four-chuck tube laser machine processes the entire range of heavy profiles used in the structural industries.

The Cypcut tube heavy module applies automatic thermal compensation on thick walls, preventing part deformation at the end and ensuring correct geometry even on 16 m profiles.

Maximum wall thicknesses per material (in the maximal configuration)

• Carbon steel S235/S355 (max. wall thickness): 20 mm
• Stainless steel 304/316 double: 16 mm
• Low-alloy steel S420/S460: 18 mm
• Marine grade structural aluminum: 14 mm

How the LAZIRON T4 model works

The workflow of a LAZIRON LAZIRON T4 four-chuck tube laser machine is built for heavy profiles where every handling of the tube costs time and a risk of damaging the material.

1. The operator loads the tube with a crane through the main chuck, supported on the intermediate roller system.
2. The 3D sensor scans the entire tube coarse + fine to establish the dimensional deviations from the CAD model.
3. The 4 chucks close synchronized on the optimal positions calculated by Cypcut.
4. The dynamic intermediate chucks position themselves automatically to eliminate deviation over the entire length.
5. The RayTools head runs the program with continuous autofocus and thermal compensation, while the chucks synchronize in real time.
6. At the end, the finished parts fall onto the discharge conveyor or are unloaded with a crane, and the residual tube is removed with a crane.

For integration with other metal processing equipment, the machine connects natively to tube bending machines and to the other LAZIRON lines through a common MES.

Frequently asked questions about the four-chuck tube laser machine

When does the investment in a LAZIRON T4 four-chuck tube laser machine pay off?

Four criteria: structural profiles over Ø350 mm or over 250×250 mm, walls over 14 mm, lengths over 12 m, or requirements for absolute precision over the entire length of the part. Below these criteria, the T3 or T3L models offer a better investment-to-result ratio. The T4 is dedicated exclusively to industries with critical structural requirements (offshore, naval, heavy machinery, bridges).

What is the practical difference between 3 and 4 chucks?

The 2 dynamic intermediate chucks (instead of 1 on the T3 model) allow supporting the part at 4 points simultaneously, eliminating any sag of the tube under its own weight. On 16 m profiles with 20 mm walls and a weight of 800-1500 kg, the natural deviation without intermediate support would be 25-40 mm, incompatible with the precision requirements of the offshore industry.

What laser power should I choose for a LAZIRON T4 four-chuck tube laser machine?

For walls 2-8 mm: 3 kW is sufficient, but rarely justified on a T4 machine. For walls 8-14 mm and typical industrial production: 6 kW is the optimal configuration. For walls over 14 mm and maximum speeds: choose 8-12 kW. Sources over 12 kW on the T4 are used only for applications with very high volumes and thicknesses over 18 mm.

How much do I save compared to cutting with an industrial circular saw plus joint welding?

On a structural part of 15 m that would otherwise be made of 2 pieces welded end-to-end, the total saving is 60-90 minutes of labor (cutting + edge preparation + welding + NDT inspection) plus 2-4 kg of electrode plus the elimination of the risk of thermal deformation. At an average cost of 35-45 EUR/hour, the saving per part is 35-65 EUR, plus the clearly superior mechanical quality of the monoblock part.

What training and what maintenance does it require?

For the operator: 5-10 days of on-site training on operating 4 synchronized chucks, Cypcut tube heavy programming and anomaly diagnosis. Maintenance: a complete kit every 800 hours (lubrication of intermediate chuck rails, calibration of 3D sensors), six-monthly synchronization inspection. LAZIRON includes the first 2 maintenance kits in the warranty and unlimited on-site training in the first year.

ROI calculation for a LAZIRON four-chuck tube laser machine

The decision to invest in a four-chuck tube laser machine is not made on the basis of technical specifications alone, what matters is how the equipment translates into real monthly cash-flow figures for your tube processing workshop.

For workshops that currently subcontract laser cutting on tubes at 1.0-1.5 EUR/linear meter cut plus material cost, internalizing with a LAZIRON four-chuck tube laser machine reduces the effective cost per processed meter by 60-75%. At a monthly volume of 800-1500 linear meters processed internally instead of subcontracting, the return on investment is achieved in 18-30 months under current market conditions in Romania.

The additional margin comes from three directions: the saving compared to subcontracting, offering cutting services to external local clients (1.2-1.8 EUR/m at the level of the Romanian market in 2026) and reducing delivery times to end clients by 40-60%, which allows premium prices on urgent orders or those with short deadlines.

Why choose LAZIRON for a four-chuck tube laser machine
