SENFENG recently completed the installation, commissioning, and operation training of an SF4020NP fiber laser cutting machine in the United States. The project was carried out by SENFENG after-sales engineer Mr. Wen, who provided professional technical support throughout the entire process, including machine assembly, mechanical adjustment, electrical connection, cutting parameter optimization, and operator instruction.

The installation involved multiple stages, from initial machine setup and component assembly to final cutting verification and maintenance training. With careful commissioning and process optimization, the SF4020NP was successfully prepared for daily production applications.

Equipment Unpacking and Initial Installation

July 20, 2026

The installation project began with unpacking the machine and carefully removing the equipment from its transportation frame.

After preparing the installation area, the engineer completed the foundation setup, installed the anchor plates, and secured the machine position with expansion bolts. The machine feet were installed, and the equipment was precisely positioned for further assembly.

The cutting platform support structure was then assembled, followed by the installation of the blade table and fire-resistant bricks. The updated platform structure design helped simplify the installation process and improve overall assembly efficiency.

The laser source was installed inside the air-conditioning cabinet, while the water chiller was positioned and connected. The cooling system was filled with coolant, pipelines were arranged, and cable routing was organized.

Additional work included side panel installation and preparation of the compressed air connection system.

Mechanical Assembly and Electrical Integration

July 21, 2026

The engineer continued with detailed machine assembly and adjustment work.

The slider components were installed and inspected to ensure smooth movement of the machine axes. Servo motors were mounted, and electrical wiring was arranged according to the machine system requirements.

The cutting head was installed and connected, followed by cable management and inspection of the motion system.

After completing the main mechanical and electrical installation, the engineer carried out a comprehensive check of the machine structure and prepared the equipment for commissioning.

Power-On Testing and Functional Adjustment

July 22, 2026

The next stage focused on system activation and functional testing.

The engineer coordinated the power connection process and completed electrical checks before starting the machine. After power-on, all major systems were inspected, including the control system, drive system, and axis movement.

During testing, the engineer identified a signal connection that required adjustment and completed the wiring optimization. After the correction, the machine movement was tested again, confirming stable and accurate operation of the X-axis system.

Cutting Process Optimization and Operator Training

July 23-24, 2026

After completing the initial commissioning, the engineer started cutting parameter optimization and practical operation training.

A series of material tests were carried out to establish suitable cutting parameters for different applications, including:

• 1/4 inch stainless steel
• 18 gauge stainless steel
• 20 gauge stainless steel
• 3/8 inch stainless steel
• 1/4 inch aluminum

During the training sessions, operators learned how to operate the machine, adjust cutting parameters, use the control software, and perform standard cutting procedures.

Through hands-on practice and real cutting operations, operators became familiar with the complete workflow of the SF4020NP fiber laser cutting machine.

Production Cutting Tests and Application Verification

July 27, 2026

The engineer continued the production training and conducted further cutting demonstrations.

Full-sheet cutting tests were completed on different stainless steel materials, including:

• 3/8 inch stainless steel sheets
• 1/4 inch stainless steel sheets

The cutting results were evaluated, and final parameter adjustments were completed to ensure consistent cutting quality and reliable machine performance.

The engineer also reviewed practical operation techniques and answered questions related to daily production use.

Software Training and Preventive Maintenance Guidance

July 28, 2026

On the final day of the project, the engineer provided additional software training and reviewed the complete operating process with the operators.

The training covered:

• Machine operation procedures
• Software workflow
• Cutting parameter management
• Daily maintenance requirements
• Consumable inspection and replacement

During the maintenance session, the engineer performed a detailed inspection of the auxiliary systems and identified an oil sealing point requiring optimization in the air compressor system. On-site adjustment was completed, and follow-up sealing components were prepared to further improve long-term reliability.

Project Completion

After completing installation, commissioning, cutting verification, and operator training, the SF4020NP fiber laser cutting machine was successfully placed into operation.This project demonstrated SENFENG’s professional after-sales service capability, providing customers with comprehensive support from equipment installation to production application. Through precise setup, process optimization, and detailed training, SENFENG helps users achieve efficient and stable laser cutting performance.
