Advantages of the product

Unmatched Precision and Speed

Our fiber laser engraving machines utilize advanced galvo technology and high-frequency pulse control, achieving engraving speeds up to 10,000 mm/s with micron-level accuracy. This ensures intricate designs and consistent results even on complex geometries, boosting your production throughput by up to 40%.

Superior Durability and Low Maintenance

With a mean time between failures of over 100,000 hours, our lasers are built for continuous industrial use. The air-cooled design eliminates the need for external chillers, reducing downtime and maintenance costs. Optical components are sealed and protected, ensuring consistent performance in dusty or humid environments.

User-Friendly Software and Flexible Integration

Our proprietary software supports CAD/CAM formats, allowing seamless import of vector and raster images. It offers real-time monitoring, automated batch processing, and network connectivity for smart factory integration. Additionally, customizable fixtures and rotary attachments enable 360° engraving on cylindrical objects, offering unparalleled flexibility.

A fiber laser engraving machine is a specialized system that uses a solid-state fiber laser source to create permanent marks on metal surfaces through annealing, ablation, or color change. Operating at 1064nm, these machines achieve absorption rates over 70% on most metals, including reflective alloys. For a tool manufacturer, a 50W fiber laser engraving machine marks 8,000 high-speed steel drill bits per hour with depth-controlled logos (0.03mm deep) that survive 500 drilling cycles. A case study from the aerospace industry shows engraving titanium alloy turbine blades: a 30W MOPA fiber laser produces black annealing marks with no material removal, maintaining aerodynamic surface integrity while providing 100% traceability. The machine’s core components are the laser source (20W to 100W), galvanometer scanner (speed up to 12,000 mm/s), and field lens (70x70mm to 400x400mm). For the medical device industry, a 20W fiber laser engraving machine marks 316L stainless steel surgical instruments with UDI barcodes (0.5mm x 0.5mm) at 0.8 seconds per code, meeting FDA 21 CFR Part 830 requirements. Another application is automotive parts: a 50W machine engraves QR codes on aluminum pistons (3 seconds each) with 0.1mm depth, readable after 200,000 engine cycles. The machine’s software supports variable data, serialization, and database linking, enabling full traceability. For decorative applications, a MOPA fiber laser (20-50W) creates colored marks on stainless steel: by adjusting pulse width (2-200 ns), users achieve blue, gold, red, and green hues. A luxury watchmaker uses a 20W MOPA machine to engrave serial numbers and brand logos on gold and titanium watch cases, with 0.02mm line width and no post-processing. The machine requires minimal maintenance: clean the protective window weekly, replace it annually. The fiber laser source has a lifespan of 100,000+ hours with no consumables. For high-volume production, the machine can integrate with pick-and-place automation or conveyor systems. To select the appropriate power (20W, 30W, 50W, 100W) and field lens for your fiber laser engraving machine – whether for deep engraving, color marking, or high-speed coding – contact the provider with your sample parts for a free test engraving and detailed specification proposal.

Frequently Questions

What metals can this engraving machine work on?

The engraving machine works on all common metals including stainless steel, carbon steel, aluminum, brass, copper, titanium, and hardened tool steel. It also handles coated metals and anodized surfaces. With optional fiber laser source, it can mark precious metals like gold and silver. The automatic power adjustment ensures clean results without damaging soft metals.

How deep can your engraving machine cut into metal?

Depth range is adjustable from 0.01mm to 0.5mm per pass, depending on material hardness and laser power. For deeper marks, multiple passes can be programmed automatically. The machine maintains consistent depth across the entire engraving area of 300x300mm (standard model). Maximum practical depth for serial numbers and logos is 0.2mm on steel.

Can this engraving machine be used for marking plastics and wood?

Yes, with appropriate power settings. The fiber laser version is ideal for marking plastics (ABS, PC, nylon) and painted surfaces. For wood and acrylic, a CO2 laser module can be installed as an option. The machine automatically switches profiles to prevent burning or melting. Always request material testing samples first.

Revolutionary Performance with Fiber Laser Technology

Tianchen Laser’s fiber laser engraving machine leverages the latest generation of pulsed fiber lasers, offering peak power up to 100kW and pulse width adjustable from 2 to 500ns. This enables both ultra-fine micro-marking and deep engraving in a single pass. The system’s galvanometer scanning speed reaches 10,000mm/s, and the marking field is distortion-free across the entire area, thanks to F-theta lenses. More importantly, our proprietary control algorithm ensures consistent mark depth and darkness even at high speeds, differentiating us from lower-quality lasers that produce inconsistent results. The machine’s structural design incorporates a rigid cast aluminum base and a thermally stable optical mount, minimizing drift due to temperature fluctuations. Moreover, the laser head is IP65-rated, protecting against dust and water spray, making it suitable for cleanroom environments. An optional smoke extraction system with automatic filter cleaning ensures a clean work area and keeps op
