Industrial Metal Engraving Applications
- Industrial tools and hardware: serial numbers, scales, logos, Data Matrix codes and controlled-depth engraving on qualified steel, carbide and coated parts.
- Automotive and machinery components: traceability marks on bearings, gears, fasteners, valves, nameplates and machined assemblies.
- Electronics and electrical parts: permanent identification on metal housings, connectors, heat sinks and selected laser-responsive polymers.
- Jewelry and metal accessories: personalization on approved gold, silver, stainless steel, titanium, brass and coated parts with part-specific fixtures.
- Medical-device supply: validated marking on compatible instruments and components only within the customer’s documented regulatory and cleaning process.
- Contract marking and personalization: variable text, logos, barcodes and 2D codes for small batches or mixed-part production.
If your part is not listed, send the material grade, coating, drawing, artwork and required mark. A sample trial can confirm absorption, contrast or depth, heat input, readability, extraction and fixture strategy before quotation.

Metal Marking Samples and Qualification
Materials and Process Qualification
A 1064 nm fiber source is commonly selected for steel, stainless steel, aluminum, brass, copper, titanium, precious metals and many coated metals. Some engineered polymers can mark after SDS review and testing. Leather, fabric, glass, paper, clear acrylic and stone generally require another source. Every alloy, coating, finish and heat-sensitive assembly must be qualified on a representative sample.
Typical Industrial Users
Typical users include tool and hardware manufacturers, automotive suppliers, electronics factories, jewelry workshops, nameplate producers, contract marking services and small-part traceability teams. Production acceptance defines loading, focus, fixture changeover, extraction, code inspection, cycle time and surface finish.
Core Fiber Engraver Components
Controller and Engraving Software
The configured controller and supplied software manage text, logos, serial data, barcodes, Data Matrix codes, vectors and raster artwork. Board revision, firmware, source protocol, driver, import formats and lens-correction file are confirmed with the delivered system.
LightBurn Pro can be offered only when the current version supports the delivered galvo board, driver and source protocol. The original machine configuration and correction file must be backed up before changing drivers or software.
Red-Light Box Preview
The visible red-light box is a positioning aid for checking approximate field placement before marking. It does not prove focus, lens calibration, rotary alignment or laser safety; final position is verified on a non-production sample.
Red-Light Contour Preview
The contour preview traces the artwork boundary to check whether the job fits the part. Offset, field distortion, perspective and fixture movement must be calibrated, and the visible guide does not indicate the invisible 1064 nm beam path.
Configured 1064 nm Fiber Source
Raycus, MAX, IPG or JPT sources can be evaluated by exact model, rated power, Q-switched or MOPA architecture, pulse-frequency range and pulse-width behavior. Higher power does not automatically improve finish; material, spot size, heat input, field lens and scan strategy are selected from customer samples.
JCZ Galvo Control Card
The JCZ or other quoted control card coordinates source timing, galvanometer motion and workstation I/O. Exact hardware, firmware and electrical integration must match the delivered source and safety design; software control does not replace independent safety controls.
Calibrated Galvanometer Scan Head
The dual-axis galvanometer moves the beam across the lens-corrected field. Scanner travel speed is not a production-cycle guarantee; artwork, fill, material, power, depth and thermal limits define throughput. Auto-focus and 3D scanning are separately engineered options.
Ring and Small-Part Rotary Fixture
A compact rotary can support inside or outside engraving on compatible rings and small cylindrical parts. Chuck range, concentricity, step resolution, surface protection, focal distance and Z clearance are confirmed on the customer part.
Flat-Sheet and Small-Part Fixture
A flat-part fixture can locate tags, nameplates, sheet, tools and small components. Usable opening, jaw material, part thickness, flatness, repeatability and protection against scratches are selected for the application.
Cylindrical Rotary Fixture
A chuck or roller rotary can index compatible cylindrical parts. Diameter, length, weight, taper, focal position, support method and Z clearance are confirmed before production.
Fiber Laser Engraver for Metal FAQ
Which materials can a fiber laser engraver for metal process?
Fiber sources are well suited to steel, stainless steel, aluminum, brass, copper, titanium, precious metals and many coated metals. Results vary by alloy, plating and finish. Some polymers mark after SDS review and testing; leather, fabric, glass and clear acrylic usually require a different source.
Which 30-100 W fiber source should I choose?
Common quoted fiber options are 30, 50, 60, 70 and 100 W. Choose the exact Q-switched or MOPA source, field lens and pulse range from the material, required contrast or depth, smallest feature, acceptable heat input and production target.
What engraving depth can a fiber laser achieve in metal?
There is no universal engraving depth. Material, source architecture, rated power, lens, spot size, passes, hatch strategy, heat limit and cycle time all affect removal. Controlled depth must be measured on a representative customer sample.
How does a fiber laser engraver compare with a CO2 laser?
A 1064 nm fiber laser is commonly selected for metals and selected laser-responsive plastics. A 10.6 µm CO2 laser is generally better for many organic materials, wood, paper, leather and acrylic. UV or green sources may be preferred for fine marking on heat-sensitive coatings and polymers.
How should the field lens and workstation be maintained?
Power down and isolate the workstation before cleaning. Keep fixtures, extraction paths and guards clean. Do not touch the field lens; use only approved lens tissue and optical-cleaning fluid when inspection shows contamination. Internal optics and optional interlocks should be serviced by trained personnel.
Which controller, software and file formats are supported?
The supplied EZCAD2, EZCAD3, SeaCAD or other workflow depends on the delivered controller. Common imports include vector, raster, text and variable-data formats, but the exact list must be confirmed. LightBurn Pro is optional only for a supported galvo board, driver and current version.
What source life and warranty are provided?
Service life is not a guaranteed fixed hour count. It depends on the exact source model, duty cycle, temperature, contamination, power quality and maintenance. The quotation must identify source and workstation warranty terms, exclusions, service procedure and spare-parts support.
What are the advantages over inkjet or mechanical engraving?
Fiber engraving is non-contact, supports software-driven variable data and can create durable marks without ink or cutting-tool wear. It still requires correct fixtures, extraction, validated parameters, optical maintenance and inspection; mechanical engraving remains useful for tactile or traditional finishes.
