In response to these technological limitations, domestic laser equipment manufacturers have been actively seeking breakthroughs in the field of medium and thick plate cutting. After continuous efforts and exploration, PRIMALASER has finally achieved milestone technological achievements: the newly launched S series v2.0 ultra-high power fiber laser cutting machine (Figure 1), with a maximum power of up to 30kW, has ultra-high speed and acceleration, supplemented by intelligent configurations and functions such as automatic edge finding, automatic nozzle replacement, automatic focusing, and non-inductive perforation. The overall performance and technical indicators have reached international leading levels, It can achieve fully automatic and unmanned production.
Main advantages of ultra-high power fiber laser cutting machine
The equipment adopts pearlitic gray iron bed (Figure 2). Due to the existence of pearlitic matrix, the strength and hardness of parts are 20% higher than those of ferrite matrix (Figure 3); Moreover, there are small graphite flakes in the uniformly distributed pearlite matrix. Compared to welded bed bodies and ordinary cast iron bed bodies, the equipment can achieve higher structural rigidity and excellent vibration reduction and creep resistance.
Based on the above, the overall mechanical structure of the equipment maintains the characteristics of small deformation and low vibration under ultra-high speed and acceleration conditions, thereby achieving extremely high machine tool accuracy, extending the customer’s equipment iteration cycle, and reducing customer usage costs.
Triple edged ultra-high voltage honeycomb aluminum crossbeam
Utilizing aviation grade aluminum alloy, the overall triangular ultra stable structure has strong anti twisting and anti overturning performance, and the mechanical properties are the best; Honeycomb cavity design, anti deformation, can effectively disperse internal and external stress, and structural stability is high; Ultra high pressure plastic production, with a dense structure and significantly improved strength, and equipment related characteristics are shown in Table 1.
On the one hand, the most stable structural form is obtained, and on the other hand, the rigidity of the gantry crossbeam is improved. At the same time, ultra-high pressure plastic production process is adopted to optimize and improve the principle, structure, and production process, achieving the lightest quality and highest rigidity, ensuring high-speed and high-precision application requirements.
Disruptive function of ultra-high power fiber laser cutting machine
⑴ Intelligent processing.
The intelligent processing function can automatically identify and replace nozzles based on the thickness and material input by users, and achieve functions such as automatic calibration, edge finding, processing, and platform exchange, eliminating the repetitive operation of customers cutting plates in bulk, reducing labor intensity, and improving user processing efficiency.
⑵ Zero second insensitivity perforation.
1) Stepless perforation, significantly reducing perforation time by about 75% and improving processing efficiency;
2) Continuous perforation has high stability, reducing the waste hole rate from about 5% to 0.2%, improving the integrity of the workpiece;
3) High accuracy, less slag accumulation, stable follow-up, stable starting point, ensuring the best cutting section;
4) Reduce perforation time, save gas, reduce electricity consumption, reduce the risk of damage to lasers and cutting heads, and improve material utilization;
5) Packaging technology, which is easy to learn and easy to use, simplifies complexity for different processing scenarios and needs in one step.
(3) Thick plate limit small hole cutting.
In the field of laser cutting, the industry has always believed that the thickness of the plate is the minimum diameter for cutting small holes, while the S series has achieved a minimum aperture of 0.2 times or even lower than the plate thickness (Figure 4).
(4) Perfect sharp corner cutting process.
The perfect sharp corner cutting process is a new technology developed by Bond for high-quality cutting of carbon steel thick plates. Compared to the previous standard cutting process, the new process has faster bright surface cutting speed and smaller cross-sectional slope (35mm carbon steel with 15 wires on one side). The sharp cut product is shown in Figure 5.
High linkage speed. Maximum linkage speed: 200m/min; Maximum linkage acceleration: 4g Equipped with the world’s highest power equipment. The S series v2.0 version is currently the world’s highest power laser cutting equipment, breaking the monopoly of foreign technology. The thickness of cutting stainless steel has been increased to 130mm (Figure 6), and carbon steel can reach 70mm (Figure 7), which is also a disruptive breakthrough for medium and thick plate processing equipment.
