Fiber Laser Marking Machine For Metal

The cabinet design adds several useful features that desktop units do not have. The large work table is made of anodized aluminum and measures 400mm x 500mm or more. So you have plenty of space for jigs, fixtures, and many parts at once. The Z‑axis lift has a stroke of 300‑400mm, so the laser head can move up for tall parts or down for fine focus adjustment. The cabinet doors have safety locks that stop the laser right away if you open them during work, so operators are safe from accidental exposure. A built‑in fan and filter removes smoke and fumes from metal marking, so the work area stays clean. The machine also has a red dot pointer for exact positioning and an adjustable focus lever for quick setup.

The GRT‑20WFL marks almost all metals used in factories and shops. On stainless steel, it makes a black, heat‑annealed mark that resists rust and cannot be wiped off. On aluminum, it makes a white or dark gray engraving, depending on the surface finish. On carbon steel, the mark is a clean, silver engraving. On coated or anodized metals, the laser removes the coating to show the bare metal underneath, so you get high contrast. The machine also marks brass, copper, titanium, gold, silver, and platinum. The marking depth can be from surface annealing (no depth) up to 0.3‑0.5mm for deep engraving, and you control it by changing power, speed, and number of passes.

Desktop lasers work well for small parts and occasional use. But for daily production in a factory, the cabinet machine is better. The enclosed design keeps dust and fumes inside; desktops spray them into the room. The larger work area means operators can load many parts in one batch. The safety locks meet factory safety rules that desktop units often fail without an extra enclosure. The cabinet also protects the laser parts from dust, moisture, and accidental hits, so the machine lasts longer. So for wholesale buyers who sell to manufacturers, the cabinet version is the recommended type.

The GRT‑20WFL cabinet machine has standard mounting points for a rotary axis attachment. This extra part lets the laser mark round metal parts like pipes, tubes, rings, shafts, and fittings. The rotary chuck turns the part exactly while the laser marks around it. Because the cabinet has a large inside space, the rotary attachment can handle parts up to 150mm diameter and 400mm length. This is very useful for marking metal tubes, hydraulic cylinders, engine valves, and jewelry. Desktop lasers often have trouble fitting a rotary attachment because they are too small.

The machine runs EZCAD control software, which is the global standard for fiber laser marking. The software takes files from AutoCAD, CorelDRAW, Adobe Illustrator, and SolidWorks. It does automatic serial numbers, date and time stamps, bar codes, QR codes, and 2D Data Matrix codes. For metal marking, the software has special settings for different alloys. The red light preview shows you exactly where the mark will go before the laser fires, so you do not waste parts. For high‑volume production, the cabinet machine can work with foot pedals, bar code scanners, or PLC systems for automatic batch marking.

The GRT‑20WFL cabinet machine is made for non‑stop factory work. The laser source is a real Raycus 20W fiber module rated for 100,000 hours. The scanning head uses Sino‑Galvo technology for fast, accurate beam positioning. The cabinet frame is welded steel with a powder‑coat finish. The machine has CE certification for laser safety, including Class 4 laser protection with interlocked doors. There is an emergency stop button in a clear spot. For overseas buyers, the machine comes in 110V or 220V.
