1. Product Overview

Our new 4-axis fiber laser hardening machine is a high-power, large-stroke industrial surface hardening solution purpose-built for long roller and rotary heavy-duty metal components. Designed by howweld, and resolve common industrial pain points including low surface hardness, poor wear resistance, and short service life of heavy mechanical parts, this laser hardening equipment adopts advanced multi-axis linkage control and premium laser core configuration to deliver stable, repeatable, and high-efficiency surface hardening for industrial hydraulic cylinder rods, heavy-duty swivel tubes, and rotor shafts.

Featuring a genuine Han’s Laser 600μm laser generator and stable 6000W high-power laser output, the machine is equipped with a full-size 6-meter workstation that supports one-pass processing for workpieces up to 6 meters in length — ideal for ultra-long roller and shaft-type parts. The professional XYZ linear axis + rotary 4th-axis synchronous system enables uniform, full-circumference laser hardening on long rotary components, filling the gap in the market for large-scale long shaft laser surface strengthening equipment.

2. Core Features & Competitive Advantages

Compared with traditional flame quenching and integral heat treatment, our 6000W 4-axis fiber laser hardening machine offers outstanding advantages in processing accuracy, consistency, workpiece deformation control, and production efficiency. It is specifically optimized for long heavy-duty industrial shafts and tubular parts, providing reliable surface hardening results and helping manufacturers reduce scrap rate and improve part durability.

2.1 High-Power Stable Laser Output, Excellent Hardening Effect

Equipped with an original Han’s 600μm laser head and 6000W high-power laser source, the equipment delivers highly concentrated and stable laser energy distribution. It achieves precise and uniform surface strengthening with a final hardness of HRC 50–55. The laser-hardened layer features a dense, fine martensite structure without cracks, pores, or overheating defects. The process significantly improves surface wear resistance and fatigue resistance while preserving the core toughness of hydraulic rods, swivel tubes and rotor shafts — avoiding the brittleness caused by traditional overall quenching.

2.2 6m Super-Long Workstation, Adapt to Large-Size Workpieces

The customized 6-meter extended workstation supports full-length one-clamp processing for 6m long roller parts, hydraulic cylinder rods and heavy swivel tubes. Traditional small hardening machines require segmented processing and repeated clamping, which leads to inconsistent hardness, splicing marks and low efficiency. Our 6m workstation ensures one-time integral hardening, uniform hardness throughout the entire long workpiece, greatly improving batch production consistency and throughput for large heavy-duty components.

2.3 4-Axis Linkage, Full-Angle Precision Processing

The 4-axis linkage system (XYZ linear axes + rotary axis) realizes synchronous processing on flat surfaces, cylindrical outer diameters, inner circumferential surfaces and irregular curved surfaces of rotary parts. For long shafts and tubular workpieces that require 360° uniform hardening, the rotary 4th-axis provides steady and precise rotation speed control, effectively solving uneven hardening, soft bands and local insufficient hardness problems commonly seen in traditional processing.

2.4 Low Deformation & High Efficiency, Save Production Cost

Laser surface hardening is a localized rapid heating and self-quenching process, with an extremely small heat-affected zone and nearly zero workpiece deformation. Unlike traditional high-temperature integral quenching, it requires no subsequent straightening or heavy polishing, greatly reducing material waste and rework costs. The fully automatic 4-axis linkage operation minimizes manual intervention, lowers long-term production and maintenance costs, and extends the service life of industrial shaft and tube components by 2–3 times.

3. Main Industrial Applications

This 6000W 4-axis fiber laser hardening machine is widely used for surface hardness enhancement and wear resistance improvement of heavy-duty mechanical components in hydraulic systems, construction machinery, mining equipment and industrial transmission systems. Its most typical processing applications include the following key parts:

• Industrial Hydraulic Cylinder Rods: Improve surface hardness and wear resistance of hydraulic piston rods, effectively resist friction and corrosion during high-frequency telescopic operation, avoid surface scratching and oil leakage, and improve the stability and service life of hydraulic systems.

• Heavy Duty Top Swivel Tubes: For long-size heavy-duty rotary pipe fittings, overall uniform surface hardening is realized to enhance torsion resistance and wear resistance, adapt to high-load and high-strength rotary working conditions, and reduce component replacement frequency.

• Rotor Shafts: Precision hardening treatment for various mechanical rotor shafts, motor rotor shafts and transmission shafts improves surface fatigue resistance and impact resistance, ensures stable operation of high-speed rotating equipment, and meets the long-term high-load operation requirements of industrial equipment.

4. Conclusion

To sum up, our 6000W 4-axis fiber laser hardening machine with Han’s 600μm laser configuration and 6m ultra-long workstation provides a high-precision, low-deformation and cost-effective laser hardening solution for long hydraulic cylinder rods, heavy-duty top swivel tubes and rotor shafts. It effectively upgrades the surface performance of heavy industrial parts, solves wear, deformation and short service life issues, and helps manufacturing enterprises improve product quality and market competitiveness.
