SENFENG recently completed the installation and training of a new 3015H 12kW fiber laser cutting machine equipped with a Max laser source for a customer in the United States. The project was led by our after-sales engineer Mr. Fan Deshuo, who provided full on-site technical support, electrical coordination, assembly, commissioning, and operator training. The process involved multiple stages due to on-site power constraints and required adjustments, but the installation was completed successfully.

Site Preparation and Base Work

Oct 29, 2025
During the initial visit, the machine was already placed at the factory, but the customer had not installed anchor bolts or prepared the foundation. After discussion, the customer cleared the area, repositioned the machine, marked the base lines, and prepared the ground anchors.
Additionally, the customer reported delays from the local power company, with no guarantee of power supply for the following week.
During inspection, the Y-axis slider lubrication tube was found cut and needed to be sourced locally.

Frame Installation and Cable Arrangement

Oct 30–31, 2025
The platform was aligned and the machine was leveled. Although the front frame had been pre-installed, it had to be removed to install the beam. With no lifting equipment available, the engineer used a forklift to assist with beam installation.
Subsequent tasks included installing cable trays, tank chains, wiring, routing fiber cables, securing the cutting head, installing limit switches, and mounting sheet metal covers, screens, and cameras.

Electrical Work and System Integration

Nov 3–4, 2025
A large amount of the wiring lacked identification tags and required reconnection based on schematics. Some cables had been extended and coiled inside the electrical cabinet. The engineer reorganized the wiring, installed the oil reservoir, motors, and top sheet metal, and laid the graphite board.
The customer’s electrician later required the transformer to be repositioned because the bend radius of the wires was insufficient, which forced relocation of the laser cabinet and power cabinet. All cables were re-routed and reconnected.
The chiller signal cable and water lines were connected, and the system awaited final power preparation.

Power-On, Debugging, and Troubleshooting

Nov 6–7, 2025
The electrician completed the wiring, but the neutral and ground on the transformer output were bonded together. The customer insisted this was a federal regulation and could not be separated. Voltage was measured and found stable.
During power-up, the IPC experienced intermittent power loss. After inspection, the issue was traced to a loose power connector, and the IPC returned to normal.
Laser activation required a permanent password because all short-term passwords had expired. After unlocking, coaxiality was checked, photosensitive paper tests were completed, and cutting tests were performed.
Cutting trials on 3mm, 4.5mm, and 9mm with nitrogen were successful. The facility did not allow oxygen use, so 19mm testing could not be performed. The 9mm sheet showed some overburning; adjustments indicated the material was likely alloy steel, as it could be picked up with a magnet.
A light curtain was installed and tested, and additional training was provided on optical path adjustment, changing ceramic rings, and replacing lenses.

Operator Training and Software Support

Nov 10–12, 2025
Operator training was conducted by Engineer Li, with Mr. Fan assisting. The customer already had operational experience and quickly understood most functions. Practical cutting exercises were completed.
CypNest software required company authorization for download, and installation continued the next day.
Operators practiced full-sheet nesting, cutting tests, and general operation. The customer ran out of nitrogen and awaited replenishment the next day.
Final guidance included checking nozzles after changing processes, routine maintenance tips, and Q&A. The customer signed the acceptance form and took photos to complete the project.
