SENFENG has finalized the on-site installation and commissioning of an SF1503CH 6kW coil-fed laser cutting line in the United States. The project was led by after-sales engineer Mr. Zhai Anjian, who oversaw mechanical verification, leveling system tuning, motion calibration, parameter configuration, and structured operator training.

The primary objective of this deployment was to fine-tune the leveling unit and synchronize the feeding and cutting systems to ensure reliable flatness control and consistent cutting accuracy for coil materials.

System Inspection and Mechanical Fine-Tuning

February 2, 2026

A comprehensive inspection was carried out upon arrival to confirm overall system readiness. The laser cutting module was functioning properly, allowing focus to shift toward optimizing the leveling section.

During functional testing, vertical movement of the feeding roller was restricted despite normal motor operation. A detailed mechanical check identified deformation in a lifting latch near the motor assembly, which was preventing smooth motion. After reshaping and reinstalling the component, full vertical functionality was restored.

A roller limit assembly was also reinforced and precisely repositioned. Following this mechanical adjustment, the position feedback system was recalibrated to align actual mechanical coordinates with displayed values.

Hydraulic support components for the feeding carriage were completed and secured, and the cutting enclosure door alignment was adjusted to ensure smooth, interference-free operation.

Process Calibration and Material Testing

February 3–4, 2026

The leveling rollers’ reference parameters were reviewed and optimized based on stroke-limit feedback logic. Roller spacing was adjusted to guarantee proper clearance at upper and lower travel limits.

Flatness verification was performed using a 1525 mm-wide, 1.5 mm galvanized steel coil. Through iterative parameter tuning, stable leveling results were achieved, followed by cutting trials to validate processing consistency.

An additional round of testing was conducted using 1.1 mm aluminum coil. Leveling and cutting parameters were refined according to material characteristics, and multiple cutting batches confirmed reliable flatness and edge quality after process optimization.

Operator Instruction and Practical Guidance

February 5–6, 2026

Structured training sessions covered the complete operational workflow, including:

• Correct startup and shutdown sequences
• Coil loading and guided feeding procedures
• Leveling pressure adjustment
• Coaxial alignment checks
• File import under coil-processing mode
• Automated parameter selection
• Preventive maintenance essentials

Special emphasis was placed on hands-on practice to build confidence in real production scenarios.

During aluminum coil processing, additional fine-tuning ensured balanced pressure distribution across left and right leveling rollers. Independent mechanical adjustment and synchronized reconnection improved height alignment and enhanced sheet flatness consistency.

Motion Accuracy Enhancement and Parameter Correction

February 7, 2026

To further refine system precision, test sheets were used to verify symmetrical roller pressure. Independent adjustments ensured uniform contact across both sides, eliminating uneven stress conditions.

Feeding accuracy was significantly improved by correcting encoder configuration values. After recalculating the actual circumference of the feeding roller, updated parameters were entered into the control system, resulting in more accurate positioning and stable feed length control.

Production Validation and Final Optimization

February 9–12, 2026

Full production-cycle simulations were conducted, covering coil mounting, centering, leveling setup, file import, parameter configuration, and continuous batch cutting.

When processing 0.51 mm aluminum coil, minor feeding deviation was detected and traced to centering alignment within the leveling unit. Precise mechanical re-centering restored smooth, stable material travel.

Ongoing production trials using galvanized steel and aluminum coils confirmed consistent leveling quality and cutting precision. Remaining structural elements, including protective curtains and side panels, were installed to complete the system configuration.

Additional operational guidance was provided on proper use of front and rear correction rollers during feeding to prevent edge deformation. After implementing optimized procedures, stable coil tracking and consistent cutting performance were verified.

Successful Commissioning Completion

By the end of the commissioning phase, the SF1503CH 6kW coil-fed laser cutting line was fully operational and running efficiently. Mechanical alignment, feeding synchronization, leveling accuracy, and cutting quality were validated through continuous production testing.

With thorough operational and maintenance training completed, the system is now prepared for long-term, stable production. This project further demonstrates SENFENG’s dedication to delivering advanced coil processing solutions with reliable global technical support.
