Laser cutting machines are CNC equipment that utilizes high-energy laser beams for precise material cutting. Their core principle involves using focused laser beams to instantaneously melt or vaporize materials, combined with auxiliary gas to remove molten residue, achieving contactless cutting. Depending on the laser source, mainstream technologies include CO₂ lasers, fiber lasers, and solid-state lasers. Among these, fiber lasers have gradually become the preferred choice in industrial fields (e.g., metal sheet cutting) due to their high efficiency and low maintenance costs.
Laser cutting achieves precision levels of ±0.01mm with kerf widths as narrow as 0.1mm, far surpassing traditional mechanical machining and plasma cutting. This technology is particularly suited for complex geometries and high-density materials, significantly enhancing production efficiency while reducing material waste. It has emerged as a core driver of manufacturing industry upgrades
Laser cutting achieves micron-level precision, making it ideal for manufacturing precision components. For example, in new energy vehicle motor core processing, the cutting accuracy of silicon steel sheets directly impacts motor hysteresis loss and efficiency. Traditional stamping processes often cause burrs and deformation, while laser cutting controls dimensional errors within ±0.05mm, substantially improving motor performance. The CH Laser cutting machine employs a fully closed-loop control system and high-precision linear motor transmission, achieving a repeatability of 0.005mm. Its self-developed custom machine structure features an integrally welded steel bed and marble worktable, effectively minimizing machine deformation and ensuring long-term reliability and stability during high-speed operation.
Laser cutting machines handle diverse materials, from 0.5mm metal foils to 25mm acrylic plates. In aerospace applications, complex cutting demands for titanium alloys and carbon fiber composites—challenging for traditional processes—are effortlessly met by fiber laser cutters. For graphic processing, laser cutting machines offer unmatched flexibility, perfectly executing intricate designs with simple operation: users need only import drawings to complete prototyping. The CX6060L laser cutter utilizes a professional cutting system with real-time software feedback, enabling users to monitor processing status and optimize material utilization and cutting efficiency.
Laser beams act directly on material surfaces without mechanical tool contact, avoiding friction and stress inherent in traditional cutting methods. This minimizes material deformation or damage, especially critical for brittle, flexible, or thin-walled materials. Precise cutting reduces scrap, enhances material utilization, and lowers resource waste. While cutting certain materials (e.g., plastics, coated metals) may generate harmful gases or dust, these can be effectively managed via filtration systems and exhaust devices. The CH Laser 6060L high-precision laser cutter features a fully enclosed exhaust system comprising a collection hood, ducts, external purification units, and fans. Unlike traditional U-shaped designs, its cutting duct-located collection chamber leverages external fan-generated negative pressure to efficiently channel pollutants into purification systems.
Default maximum nesting layouts minimize material waste, while real-time cutting path optimization ensures precise execution, reducing scrap rates by over 60% and improving material utilization. This boosts processing efficiency by more than 40%.
Motor cores—critical components in new energy vehicle drive systems—are typically laminated from 0.2-0.5mm silicon steel sheets. Traditional stamping and welding methods face key challenges:
High hysteresis loss: Stamping burrs create lamination gaps, increasing energy loss.
Large heat-affected zones: Welding embrittles silicon steel, shortening motor lifespan.
Laser Cutting Breakthroughs:
Precision lamination cutting: Fiber laser cutters (e.g., CH Laser CX6060L) enable high-speed precision cutting (up to 90m/min) with smooth burr-free edges and 0.005mm repeatability, ensuring tight lamination alignment to reduce hysteresis loss.
Stress-free processing: Non-contact cutting eliminates deformation, enhancing core magnetic efficiency and boosting motor efficiency by 10%-15%.
Case study: A new energy automaker achieved 98% motor core yield (up from 85%) and 20% higher material utilization after adopting laser cutting.
Ultraviolet laser cutters process 0.1mm stainless steel foils for ultra-thin components (e.g., smartphone frames, flexible PCB brackets), with heat-affected zones under 50μm, meeting 5G device miniaturization demands. Laser cutting's penetration into these fields drives product miniaturization and performance gains. Advancements in ultrafast lasers and intelligent controls will expand applications in 3D packaging and flexible electronics.
Laser cutting proves indispensable in lithium battery separator and copper foil processing, particularly for high-precision tab forming and micro-hole drilling, enhancing energy density and safety. With cost reductions in ultrafast lasers and maturing intelligent processes, laser machining will solidify its role in battery manufacturing. For instance, 30kW fiber lasers cut 0.1mm battery electrodes at 60m/min with zero burrs, eliminating short-circuit risks.
China's laser equipment market is projected to exceed ¥35 billion by 2025, growing at a 22% CAGR. Key trends include:
High power & intelligence: Domestic 30kW fiber lasers (40% cheaper than imports) drive high-end equipment localization.
Process integration: Laser cutting-welding hybrid systems (e.g., Winbro solutions) achieve 99.5% yield in new energy battery tray processing.
Amid surging demand for precision machining, the CH Laser CX6060L stands as an industry benchmark with:
1. Ultra-high precision: ±0.01mm positioning accuracy for 0.1-5mm sheets, ideal for motor cores and electronic components.
2. Smart adaptability: Open ECAD/CAM software supports multi-format files, vision positioning, and automated loading systems.
3. Energy efficiency: 20% lower energy consumption aligns with carbon neutrality goals.
Laser cutting machines are reshaping manufacturing through a "precision revolution," evolving from efficiency tools to core innovation engines in sheet metal processing. As domestic technologies advance and applications expand, brands like CH Laser will continue driving the industry toward high-value innovation.
