How Deep Can a 50W Laser Engrave?
A 50W deep engraving fiber laser marking machine removes material at depths up to 0.5mm in a single pass on mild steel, and up to 1mm with multiple passes. This is the machine for mold and die shops, tool manufacturers, and parts that require permanent identification marks that survive machining, plating, and wear. The higher power density of a 50W source also speeds up marking on large parts and reduces cycle time on high-volume production.
Deep engraving differs from standard marking in that it physically removes material rather than changing surface color. The operator controls depth through laser power, speed, frequency, and number of passes. For mold cavity text and serial numbers that must remain legible after heat treatment, the 50W machine delivers consistent results.
What Applications Need 50W Power?
- Mold and die shops engraving cavity text and date codes.
- Tool manufacturers marking wrenches, blades, and drill bits.
- Hardened steel parts requiring deep serial numbers.
- Large parts that need wide marking areas (300mm or more).
- High-volume production where cycle time matters.

30W vs 50W: When to Step Up
If your parts are thin sheet, electronics, or light marking on aluminum, the 30W machine is sufficient. If you regularly engrave hardened steel, mark mold cavities, or need 0.3mm+ depth, the 50W machine reduces the number of passes and cuts cycle time significantly.
FAQ:
Q: Can it engrave on hardened steel?
A: Yes. The 50W machine engraves through hardened steel (up to HRC 55) at reduced speed. For very hard materials, multiple passes are required.
Q: How long does deep engraving take per part?
A: A typical serial number engraving at 0.1mm depth takes 3-5 seconds. A mold cavity logo at 0.3mm depth may take 30-60 seconds depending on size.
Q: Does it require ventilation?
A: Yes. Deep engraving produces metal dust and fumes. A fume extractor with HEPA filtration is recommended for enclosed work areas.
Q: Can it mark on brass and copper?
A: Yes. Copper and brass absorb fiber laser energy well, producing high-contrast marks. The 50W machine handles these materials at standard speed.
Q: What is the spot size and how does it affect engraving?
A: The standard 50W machine uses a 30-micron spot size for fine detail. A 50-micron spot increases depth per pass but reduces resolution. The operator can swap lenses depending on the job.
