3D Fiber Surface Platform
Large Format Fiber Laser Marking Machine
A 50W or 100W fiber marker built on a Sino-galvo 2206-3D head with a 200 mm Z range and XY travel of 1050 x 800 mm. It is made for the jobs a small bench cannot reach: deep relief, surface texturing, coating removal and marking across a large metal casting in one setup.

One-Piece Metal Process
One-Piece Metal Parts, Marked in a Single Setup
Casting, forging and welded assemblies are expensive to move and slow to re-datum. The four steps below keep the part fixed from load to release.
01
Load Once
The part is placed on the aluminium work table and located against the travel range, with no need to break it down first.
02
Auto Height Set
The column sets focus at the press of a switch, so the operator does not measure or re-clamp to reach the surface.
03
Mark the Whole Face
XY travel of 1050 x 800 mm and a 3D head cover flat, tapered and contoured areas of the same part in one program.
04
Release the Part
One setup means no return trip for a second operation, which keeps large parts moving through the cell.
Optics
A 3D Head That Reaches 1050 x 800 mm
The Sino-galvo 2206-3D head combines a 3D dynamic focus system with an adjustable Z axis, so the focal point can follow a taper, a slope or a contoured casting without distortion.
- Fine spot over a wide areaThe head keeps the beam tight even when the mark spans the full travel, which matters for deep shading and texture.
- Aluminium work tableA rigid table spreads heat and resists distortion, so large parts sit stable through long jobs.
- Column focus controlThe lifting column carries a scale, so height changes are quick and repeatable between operators.
- Low running drawThe machine draws about 460W to 580W depending on power, with a fiber source rated for long service.

The two models share the head and the controller. The difference is power, working area and machine size.

Deep Relief Capable
With the 3D head and a 200 mm Z range, the beam holds focus while the surface steps down, so relief stays sharp.
Texturing and Coating
The same head marks, textures and removes coatings, which turns one machine into a surface preparation cell.
Almost Maintenance Free
Routine cleaning of the field lens and the machine exterior is the bulk of the upkeep, with no ink or consumable to buy.

The technical table gives the standard marking area as 400 × 400 mm and 600 × 600 mm, with XY travel of 1050 x 800 mm. The product description also refers to a largest working area of 1200 x 1200 mm and a dynamic focus Z range of 300 mm; where these differ, the technical table above is the binding figure.
Where It Is Used
Industries That Mark Large Metal Parts
Deep relief, texturing and traceability on parts that are too big, too heavy or too valuable to move between machines.
Automotive & Aerospace
Serial numbers, relief detail and surface texturing on structural and powertrain components.
Tooling & Moulds
Texture, engraving and coating removal inside tooling and moulds where deep detail carries into the part.
Electronics
Marking on housings and larger metal enclosures where a small field lens would leave seams.
Medical & Jewellery
Fine personalisation and permanent identification on parts where detail and traceability both matter.
Surface Engineering
Surface Texturing, Relief and Coating Removal
The same beam that marks can also change the surface, which is why this machine is often specified for more than traceability.
Specification Notes
Options and Integration Notes
The machine is specified around your largest part, so a few choices are settled before the build begins.
- Working area400 x 400 mm or 600 x 600 mm, with larger areas reviewed against your part envelope.
- Laser sourceMAX, Raycus or JPT selected for the depth and the material you run most often.
- AutomationReady for automatic loading, robotic handling and conveyors when throughput rises.
- Sample sign-offA marked and textured sample on your own material, with the parameter file supplied.
“Our mould inserts are too heavy to keep re-clamping. The 3D head follows the contour of the insert in one program, so the texture and the identification mark come off the same setup with no seams.”

FAQ
Large Format Fiber Marking: Common Questions
It handles metals such as stainless steel, aluminium, brass and titanium, as well as non-metals including plastic, ceramic, glass and some types of stone.
The working area depends on the model. The standard marking area is 400 x 400 mm on the 50W unit and 600 x 600 mm on the 100W unit, with XY travel of 1050 x 800 mm for positioning larger parts.
It adjusts the focal length of the beam in real time, which keeps accuracy on curved or uneven surfaces and is essential when the part has changing height or complex geometry.
Automotive, aerospace, electronics, medical devices, jewellery and manufacturing, where precise engraving on large and complex parts is required.
The core components, including the laser source, are covered by our 2-year warranty, which provides timely support and replacement parts if a problem occurs.
Fiber laser marking does not need ink or cartridges. Occasional cleaning and maintenance of the lenses and machine parts is all that is required for best performance.
Engraving depth depends on the material and the laser power, and can reach several millimetres on metal. Advanced models can go deeper with multiple passes.
The machine uses an efficient air-cooled system that keeps the laser source and other components at a stable temperature during operation.
Maintenance is minimal and usually covers cleaning the optics, checking alignment and confirming the cooling system is working. The fiber source itself is known for long life and low maintenance.
Yes. It can be integrated with automatic loading systems, robotic arms and conveyors to raise throughput in large scale manufacturing.
