How Deep Can a Fiber Laser Engrave?
A standard 20W or 50W fiber laser marking machine marks logos and serial numbers to a shallow depth of 0.02-0.05mm. When the job requires deep engraving on mold cavities, tooling, or heavy-duty nameplates, a 100W or 200W fiber laser engraving machine moves into a different class. With multiple passes and a larger spot, it can engrave steel to a depth of 0.2-1.0mm, which is enough for mold text, part numbers that survive sandblasting, and decorative relief on brass and aluminum.
This machine is the bench-top deep engraving variant. It uses a pulsed fiber laser source (100W, 200W, or 300W options) with a galvo scanner, a rotating table for heavy parts, and a red-light preview system. It handles hard metals including hardened tool steel, stainless steel, carbide, brass, copper, and anodized aluminum. The workpiece sits on an X-Y-Z positioning stage (100mm x 100mm) so the operator can align it under the laser head without moving the scanner.
What It Engraves in Production
- Mold and die text: cavity numbers, date codes, and part logos on hardened steel.
- Tooling inserts: engraves fixture plates, gauge blocks, and jig surfaces.
- Brass and copper nameplates: deep-filled engraving for industrial signage.
- Stainless steel annealing: marks black on medical and food-grade stainless without removing material.
- Carbide and PCD tooling: engraves cutting tool ID and grade marks.

Who Buys a 100W Deep Engraving Fiber Laser?
This machine is for:
- Mold and die shops engraving cavity IDs and repair marks.
- Tooling manufacturers marking cutting tools and fixtures.
- Nameplate and plaque shops doing deep-filled brass engraving.
- Medical device shops annealing stainless steel parts without contamination.
- Hardware shops engraving serial numbers on parts that survive painting and sandblasting.
50W vs 100W vs 200W: Which Class
A 50W machine handles light marking and shallow annealing. A 100W machine is the minimum for real deep engraving on steel and brass. A 200W or 300W machine cuts engraving cycle time roughly in half and handles carbide and hardened tool steel more comfortably. If your daily deep-engraving work exceeds 2 hours, the 200W pays back through faster throughput.
FAQ:
Q: How long does a 0.5mm deep engraving take on steel?
A: A 100W machine takes 3-8 minutes per square centimeter at 0.5mm depth, depending on the pattern density. A 200W machine cuts that to 1.5-4 minutes. Simple text is faster than filled areas.
Q: Does it need a rotary attachment for round parts?
A: Yes, if you engrave on cylindrical parts like tools, bearings, or valve stems. The rotary mounts on the X-Y stage and indexes around the circumference. It is offered as an option at order time.
Q: Can it mark on plastic?
A: Standard fiber lasers mark engineered plastics loaded with additives (ABS with fiber additive, POM, certain nylons). They do not mark bare PP, PE, or clear acrylic. For those materials, a UV or CO2 laser is the right tool.
Q: What is annealing on stainless steel?
A: Annealing heats the surface just enough to oxidize it, producing a black mark without removing material. This is used on medical and food equipment where a recessed mark would trap contamination. The mark is permanent and corrosion-resistant.
Q: How do I fill deep engraving for contrast?
A: After deep engraving, shops fill the recess with industrial epoxy paint or metal-filled engraving compound, then sand the surface flat. Brass nameplates commonly use black fill for legibility on brushed metal.
