Advantages of the product

Ultra-High Precision for Complex Metal Engraving

Achieving engraving accuracy up to ±0.01mm, this machine guarantees sharp and consistent results even on hardened steel, aluminum, and titanium. The rigid frame and high-torque servo motors eliminate vibration, enabling micro-detailing like logos, serial numbers, and intricate patterns. With a 200W fiber laser source (optional), it delivers clean edges without burrs. Ideal for aerospace, automotive, and medical device marking. The closed-loop feedback system automatically compensates for thermal drift, ensuring repeatable quality over long production runs.

Massive Production Capacity with 10,000+ Units Annual Output

Leveraging an intelligent manufacturing base, the engraving machine benefits from a mature assembly line that produces over 10,000 units per year. This scale ensures short lead times (7–15 days for standard models) and rigorous batch testing. Each unit undergoes 48-hour burn-in and calibration using ISO-certified procedures. High-volume production also lowers component costs, offering clients competitive pricing without compromising reliability. Spare parts are always in stock, minimizing downtime for high-demand operations.

Over 29 years of focused development in intelligent metal forming solutions has led to the creation of a large intelligent manufacturing base capable of producing over 10,000 sets of core equipment annually, with business coverage in more than 100 countries and regions. The laser engraver for metal is a professional industrial-grade device dedicated to high-precision, permanent marking on various metal materials. Utilizing advanced fiber laser technology, it generates a high-energy-density laser beam that acts on the metal surface to create clear, corrosion-resistant, and wear-resistant markings without damaging the substrate. This non-contact processing method ensures zero mechanical stress and zero deformation, making it ideal for precision components in automotive, aerospace, agricultural machinery, hardware, and electronics industries. Typical applications include engraving serial numbers, QR codes, logos, production dates, and technical parameters on engine parts, gears, bearings, metal nameplates, and decorative hardware. In harsh working environments such as agricultural machinery, the engraved markings remain legible after long-term vibration, exposure, and corrosion. The equipment features ultra-high positioning accuracy, fast engraving speed, and low energy consumption, with a long-service-life laser source that reduces long-term operational costs. It supports multiple file formats and intelligent batch processing, simplifying operation and improving production efficiency. The compact and stable structure ensures reliable performance under long working hours, while the user-friendly human-machine interface lowers the skill requirement for operators. Customized solutions are available based on processing area, material characteristics, production volume, and accuracy demands. The equipment can also be integrated into automated assembly lines for online engraving, realizing unmanned production. With a strong focus on quality control and customer-centric services, this metal laser engraver provides reliable solutions for global manufacturers seeking stable and efficient marking systems.

Common problem

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 do you ensure engraving repeatability on small parts?

The machine uses a high-resolution linear encoder (0.001mm) and a servo-driven X/Y table. A pneumatic clamp or rotary axis option holds small parts firmly. The job memory stores exact coordinates, so reloading the same fixture yields identical engraving position within ±0.02mm. Camera alignment is available for pre-printed parts.

Is training included when purchasing an engraving machine?

Yes, free online training (4 hours) and on-site training (2 days) are included for the first machine. Operators receive a certificate after passing a practical test. Advanced classes (G-code programming, rotary engraving) are available at the manufacturing base. Video tutorials and a knowledge base are accessible 24/7.

Cost-effective alternative to used European machines

Was looking at a second-hand German engraver for $18k. This brand new Tianchen machine with 2-year warranty cost $12k delivered. It has more features: touchscreen, Wi-Fi, and batch report export. Six months in, zero defects. The build quality is solid – all steel panels and Japanese linear guides. Very impressed.

Lisa Anderson

Global service network gave me peace of mind

As a small business in Chile, I worried about support. Tianchen has a partner in Santiago who performed installation and calibration. The machine engraved our corporate logo on 8000 stainless steel tags perfectly. When I needed a new air nozzle, it arrived in 5 days. The English manual is clear. Excellent overall experience.
