Advantages of the product

Ultra-High Cutting Accuracy Within ±0.03mm

With nearly three decades of innovation, our metal laser cutting equipment achieves positioning accuracy up to ±0.03mm per meter. This precision is maintained even on complex geometries and thick plates up to 30mm. The advanced servo control system and rigid bed design eliminate thermal deformation, ensuring consistent cut quality across thousands of cycles. For industries like aerospace and medical device manufacturing, this level of accuracy reduces secondary processing and material waste significantly. Our in-house developed beam shaping technology delivers a smaller kerf width and smoother edge, directly improving welding and assembly efficiency. Each machine undergoes a 72-hour continuous cutting test before delivery, guaranteeing that the precision specs hold under real production loads.

29 Years of Proven Expertise in Metal Fabrication

Founded in 1995, the company has dedicated 29 years exclusively to metal forming and cutting technologies. This long history means our metal laser cutting solutions are not generic products but are refined through thousands of real-world installations. We have witnessed the transition from CO2 to fiber lasers and have mastered every technical nuance along the way. Our R&D team, many of whom have been with us for over a decade, continuously improves beam delivery, nozzle design, and cutting parameter libraries. As a result, our machines cut stainless steel, aluminum, brass, copper, and titanium with optimized parameters out of the box. This deep domain knowledge also translates into smarter troubleshooting and more effective training for your operators.

Identifying the best laser engraver for metal involves understanding the distinction between marking and deep engraving, and the technologies best suited for each. While Tianchen Laser's primary industrial focus is on high-power fiber laser cutting machines, the underlying fiber laser technology is widely recognized as the premier method for permanent, high-contrast marking and engraving on metals. For applications requiring durable, legible marks such as serial numbers, barcodes, data matrix codes, and logos on metal parts, a fiber laser marker is the industry's gold standard. Its short wavelength is readily absorbed by metals, allowing it to create a permanent, high-resolution mark without compromising the part's structural integrity or corrosion resistance. This is in contrast to CO2 lasers, which are less effective on bare metals. The "best" engraver for a specific application depends entirely on the required depth, speed, and work area. For surface marking, a compact galvo-head fiber marking machine is ideal. For tasks that require deeper engraving or larger work areas, a CNC gantry-style fiber laser, similar in principle to Tianchen's cutting machines but with lower power and specialized optics, would be more appropriate. While our core product line is concentrated on high-power industrial cutting solutions for sheet and tube, the expertise in fiber laser application is extensive. For customers seeking detailed information about metal engraving and marking capabilities and the specific equipment that would best suit their needs, we encourage you to contact our team directly to discuss your application requirements.

Common problem

What thickness of metal can your laser cutter handle?

Our metal laser cutting machines can handle mild steel up to 30mm, stainless steel up to 25mm, and aluminum up to 20mm. For thin sheets of 0.5-6mm, cutting speeds exceed 20m/min. We also offer high-power options (up to 20kW) for cutting up to 50mm carbon steel. The exact thickness depends on the laser source power and material type. Please contact our sales team with your specific requirements for a detailed cutting parameter table.

Do you provide training for operating the machine?

Yes, we provide comprehensive on-site and online training for your operators and maintenance staff. The training covers safety protocols, software nesting, machine operation, daily maintenance, and trouble shooting. Each purchase includes 3 days of on-site training at your facility. We also offer video tutorials and a remote support hotline for ongoing questions. Certification is provided after successful training.

Can you cut reflective metals like copper and brass safely?

Yes, our metal laser cutting machines are specially designed for high-reflective materials. The cutting head features back-reflection protection, and the laser source has an anti-reflection isolation module. This prevents damage to the optical components. We have pre-set cutting parameters for copper (up to 8mm) and brass (up to 6mm). Many electronics and decorative part manufacturers use our machines for these metals daily without issues.

Customer Reviews

Robert Martinez

29 years of experience shows in build quality

I have used five different laser brands in 25 years. Tianchen's machines have the heaviest bed construction and most precise linear guides I've seen. The cutting head stays calibrated for months. You can feel the engineering maturity – no cheap components, no software bugs. They even sent a senior engineer to oversee our first installation. This is a company that truly understands metal cutting, not just assembling parts.

Daniel Harris

They replaced our plasma cutter for 25mm steel

We used to cut 25mm mild steel plates with a plasma table, but the bevel and dross required grinding on every part. Tianchen's 12kW laser cutter cuts the same thickness with a near-perpendicular edge and zero dross. Grinding labor dropped 90%. The machine is also much quieter and cleaner. The initial investment was higher, but we recovered it in 14 months from labor savings alone.

Automated Production Line Integration Ready

Our metal laser cutting systems are designed as plug-and-play modules for automated production lines. Each machine features standard Ethernet/IP and Profibus interfaces, enabling seamless communication with loaders, unloaders, sorting robots, and storage towers. The intelligent nesting software automatically assigns cutting jobs to the most efficient machine and reports real-time material usage. For high-volume manufacturing, we offer a fully automated cell with a 10-pallet tower and a 6-axis robot that handles sheets up to 4m x 2m. This reduces manual labor by up to 80% and increases throughput by 35%. The same automation package supports lights-out manufacturing, allowing you to cut metal parts overnight and on weekends. Hundreds of automotive and appliance suppliers have already automated their cutting processes with our solutions.

Energy-Efficient Cutting with Lowest Gas Consumption

By optimizing the cutting head gas dynamics and using a high-efficiency fiber laser source (up to 45% electrical efficiency), our metal laser cutting systems reduce energy costs by 30% compared to conventional designs. The patented low-pressure cutting mode for thin stainless steel uses nitrogen at only 4-6 bar instead of 15-18 bar, slashing gas expenses significantly. An intelligent standby mode cuts idle power consumption to less than 100W. For a typical 2-shift operation, these savings can exceed $8,000 per year. Furthermore, the laser source is maintenance-free for 100,000 hours, eliminating consumable costs associated with lamps or mirrors in older technologies. This eco-friendly design also reduces your workshop's carbon footprint while delivering the same high-speed cutting performance.
