The SF4020HM sheet-and-tube fiber laser cutter has been successfully installed and brought into operation in the United States. Designed as a dual-purpose solution, the machine integrates sheet metal and tube cutting functions within one platform, enabling efficient processing of carbon steel, stainless steel, aluminum, and other common fabrication materials.

The project was supported on-site by after-sales engineer Mr. Wang Dongkai, who oversaw the full installation process, system integration, performance calibration, and operational training.

Equipment Assembly and Installation Process

February 6, 2026

The installation process began with the structural assembly of the machine. The upper support beam, front enclosure panels, door step frame, display system, and electrical cabinet were positioned and secured. Rear protective panels and tow-chain covers were installed to complete the primary framework.

February 7, 2026

Internal protective components such as refractory bricks and burn-resistant plates were mounted inside the cutting area. The Y-axis cable carrier was installed, and all electrical and encoder wiring was routed and connected. The exchange table motor wiring and tube-cutting harnesses were integrated to ensure stable signal transmission and power distribution.

February 9–10, 2026

The cutting head installation was completed along with side enclosures, sliding access doors, exhaust ducting, and internal lighting. The automatic exchange table was secured to its drive system.
All internal cables were carefully arranged within the tow chain to guarantee smooth movement and long-term reliability. Safety interlocks for the access doors were installed, signal lines were connected, and the cooling circuit between the laser source and water chiller was finalized.

System Integration and Commissioning

February 11, 2026

Signal connections for the laser source, chiller, and safety light curtain were completed. The compressed air and nitrogen filtration assemblies were installed together with the air compressor regulation unit. After finalizing the main power connections, the system underwent initial startup testing.
All core components operated steadily, and pneumatic connections were adjusted to ensure consistent airflow performance.

February 12, 2026

Comprehensive functional checks were carried out, including exchange table motion tests and safety system verification. Following parameter confirmation and alignment calibration, the platform operated smoothly.

Tube-cutting calibration included B-axis alignment and beam positioning optimization. Through repeated test marking and fine adjustments, precise centering was achieved.

Initial cutting trials on carbon steel demonstrated stable oxygen cutting results. Air-cutting parameters were further refined to optimize corner quality and edge finish.

Final Assembly Completion

February 13, 2026

The installation concluded with the mounting of the top enclosure and remaining side panels, completing the full mechanical setup of the SF4020HM system.

Operator Training and Production Testing

February 16–18, 2026

Multi-day operator training sessions were conducted to ensure confident and independent operation. Training covered both sheet and tube processing workflows, including:

• Cutting head alignment and calibration
• File import and parameter setup
• Lead-in configuration and cutting sequence arrangement
• Nesting software usage
• Nozzle, ceramic ring, and protective lens replacement
• Routine maintenance and inspection procedures

Practical cutting exercises were performed on carbon steel, stainless steel, and aluminum materials. The machine delivered consistent and high-quality cutting results across different applications.

Project Completion

Following complete installation, system commissioning, calibration, and structured training sessions, the SF4020HM sheet-and-tube laser cutter was officially placed into operation. The project highlights the machine’s integrated versatility, stable performance, and readiness for efficient dual-purpose production.
