The sharp corner and small hole cutting process is a core breakthrough in precision flat cutting, designed specifically for processing complex precision sheet metal parts and high-end appearance parts. To solve the problems of easy overheating of sharp corners, deformation of small holes and serious slag hanging in traditional cutting, we accurately control the laser energy output through microsecond-level power response regulation and path optimization technology, effectively solving the problem of heat accumulation at corners. It can realize right-angle cutting with an inner corner radius of 0.3mm and micro-hole processing with an aspect ratio of 15:1 (such as φ0.5mm×7.5mm). After cutting, the sharp corners are free of burrs and collapse, and the small holes are round and regular with a dimensional accuracy of ±0.02mm, without secondary grinding, which greatly improves the processing quality and qualification rate of precision parts, and is suitable for scenarios with strict requirements on details such as high-end home appliances and precision machinery.

The flying cutting process is the core process to improve the efficiency of batch processing, redefining the high-efficiency standard of flat cutting. Different from the disadvantage that traditional cutting requires 1-3 seconds of pause for each direction change, this process realizes non-stop continuous processing through the coordinated movement of the material dynamic conveying system and the cutting head. Combined with intelligent layout optimization technology, the cutting speed is increased by more than 40% compared with traditional processes, and the material utilization rate is increased to 95%, which greatly reduces the waste of leftover materials and non-productive time. It is especially suitable for batch processing scenarios such as sheet metal factories and engineering machinery parts, helping customers shorten the production cycle and improve production capacity.

The bright surface cutting process focuses on the processing needs of high-end appearance parts, realizing the integration of cutting and polishing. According to the difference of processing materials, it is divided into carbon steel bright surface cutting with oxygen as auxiliary gas and stainless steel bright surface cutting with nitrogen as auxiliary gas, which accurately meets the high-end processing needs of different materials and balances appearance quality and processing efficiency.

Oxygen-assisted carbon steel bright surface cutting is customized for the processing of high-end carbon steel appearance parts, balancing cutting efficiency and surface texture. This process uses high-purity oxygen (≥99.9%) as the auxiliary gas. During laser cutting, oxygen not only plays a combustion-supporting role to accelerate the melting of carbon steel and improve cutting speed, but also inhibits the oxidation of the cutting section by precisely controlling the oxygen flow and laser energy, finally obtaining a silver-gray bright surface section without slag and burrs, with a surface roughness as low as Ra1.6μm. The cut carbon steel parts do not need additional grinding and polishing, and can be directly used for subsequent surface treatments such as spraying and electrophoresis, which is suitable for scenarios such as carbon steel decorative panels and high-end carbon steel structural parts. While ensuring the appearance quality, it greatly improves processing efficiency and reduces the cost of subsequent processes.

Nitrogen-assisted stainless steel bright surface cutting is designed for the characteristics of stainless steel, completely solving the industry pain point of oxidation discoloration in stainless steel cutting. Stainless steel is prone to oxidation, and traditional cutting is prone to problems such as blackening and yellowing of the section. This process uses high-purity nitrogen (≥99.99%) as the auxiliary gas, which can effectively isolate the contact between air and the cutting area and avoid oxidation reactions. Combined with high-power laser and high-quality light beam, it precisely melts stainless steel and blows away the slag with high-pressure nitrogen, finally obtaining an oxidation-free, silver-white high-brightness cutting section with a delicate and smooth surface and uniform gloss, which can be directly used for high-end surface treatment processes such as anodizing, electroplating and wire drawing. This process is suitable for scenarios with extremely high appearance requirements such as stainless steel elevator panels, high-end stainless steel decorative parts and precision stainless steel accessories, perfectly presenting the high-end texture of stainless steel, while reducing secondary processing links and improving production efficiency.

Bevel cutting process is a core process suitable for welding needs in flat cutting, specially designed for the processing of various structural parts that need welding, effectively solving the pain points of low efficiency, uneven angle and need for secondary grinding in traditional bevel processing. According to welding needs, this process can accurately realize arbitrary angle bevel cutting of 0-45°, supporting various bevel forms such as V-type, U-type and X-type, and is suitable for processing multiple materials such as carbon steel, stainless steel and aluminum alloy. Through precise control of laser energy and intelligent optimization of cutting path, the bevel angle error is ensured to be ≤±0.5°, and the bevel surface is smooth without burrs and collapse, which can be directly used for welding without secondary processing, greatly improving welding efficiency and quality, and avoiding welding defects caused by insufficient bevel precision. It is suitable for processing scenarios that require a lot of welding such as steel structures, engineering machinery and sheet metal components.

Air cutting process is a practical process that balances efficiency and cost, widely used in conventional carbon steel processing scenarios. Using air as the auxiliary gas, it does not require additional investment in inert gas costs, greatly reducing the expenditure on processing consumables. At the same time, relying on high-power laser technology, it realizes efficient cutting of medium and thin plates, with fast cutting speed and strong adaptability, which can meet the batch processing needs of ordinary structural parts and conventional sheet metal parts, perfectly balancing processing efficiency and cost control, and becoming the preferred process for small and medium batch production.

Ultra-clean air cutting process is an upgraded and optimized version of air cutting, achieving dual breakthroughs in efficiency and quality. Aiming at the pain points of many burrs and the need for secondary grinding in traditional air cutting, we eliminate the excess residue at the bottom of the workpiece by optimizing the auxiliary gas ratio and cutting parameters, realizing burr-free cutting with a delicate and vertical cutting section, without secondary processing. Compared with nitrogen cutting, the cost is reduced by about 70%, and the cutting speed is increased by 50%-60%. It is especially suitable for processing medium and thin carbon steel and aluminum alloy, which not only retains the cost advantage of air cutting, but also achieves quality close to bright surface cutting, greatly improving processing cost performance and production efficiency.

Automatic nozzle changing process is a key process to improve the intelligence level of equipment and reduce manual intervention. Relying on the intelligent nozzle changing system, it can automatically complete the rapid replacement of nozzles according to the needs of different plate thicknesses and cutting processes, with a replacement time of only about 15 seconds, without manual disassembly and debugging, effectively shortening the equipment preparation time and reducing non-productive losses. At the same time, the system can automatically detect the nozzle status, avoid cutting quality problems caused by nozzle wear and model mismatch, reduce manual operation errors, adapt to batch processing scenarios with multiple varieties and specifications, and improve production continuity and stability.

Automatic light center alignment process is the core basic process to ensure cutting accuracy and stable output of laser energy. The accuracy of laser cutting directly depends on the precise alignment between the light center and the cutting head. Traditional manual light center alignment is not only time-consuming and laborious, but also prone to deviations, affecting cutting quality. Our automatic light center alignment process automatically detects the position of the laser light center through the intelligent sensing system and precise positioning technology, and real-time calibrates the deviation to ensure the perfect alignment between the light center and the cutting head, without manual intervention throughout the process. It not only improves the equipment debugging efficiency, but also ensures the precision stability of long-term continuous cutting, providing reliable guarantee for various high-precision cutting needs and avoiding the increase in scrap rate caused by light center deviation.
