What the EST-F1 (2W Fiber) is built to do
The EST-F1 (2W Fiber) is a portable / desktop marking in the laser marking machines range. An ultra-compact portable marker for fine, precise metal marking.
Marking with a fiber source is a thermal, contactless process: the beam alters the metal surface rather than cutting into it with a tool, so there is no tool wear and no mechanical load on thin shanks, bezels or findings. On this model the beam runs at 1064 nm and scans at up to ≤ 5000 mm/s.
Power is the variable that decides depth per pass, not mark quality — accuracy and speed are shared across the range. That is why a 2 W machine is specified by the job: identification marking, deep engraving, or engraving plus light cutting. The complete guide to laser marking for jewelry works through those thresholds in detail.
Capability in practice
The figures below are the ones that decide whether this machine suits a given job. The full table is in the specifications section above.
| Parameter | EST-F1 (2W Fiber) | What it decides |
|---|---|---|
| Laser power | 2 W | Surface identification marking — hallmarks, karat stamps, batch and QR codes. |
| Marking speed | ≤ 5000 mm/s | Ceiling figure; real throughput depends on fill spacing and depth. |
| Repeat accuracy | ≤ 0.001 mm | Positional repeatability between passes — what keeps small text legible. |
| Marking field | 70×70 mm | Larger fields trade a little edge sharpness for coverage per load. |
| Pulse frequency | 30–60 kHz | Higher rates suit continuous inline work; lower rates suit deeper single welds. |
Where it fits in a workshop
Marking is usually the last operation before packing, so the machine sits at the end of the bench line where finished pieces are inspected. Typical work: hallmarks and karat stamps, serial numbers for traceability, customer personalisation, and brand logos on tags and clasps.
- Logo marking — brand marks on clasps, findings and packaging inserts.
- Pendant and tag marking — logos, monograms and batch codes on flat stock.
Installation and site requirements
Most delayed commissionings come down to three things: the supply, the cooling and the route into the room. Check these against the site before the machine ships.
- Weight — 5.9 kg. Check floor loading and the lifting route; anything over 150 kg normally needs a pallet truck and a clear doorway.
- Footprint — 230 × 360 × 330 mm. Allow clearance behind and beside the machine for service access.
Operator handover covers the software, the parameter set for the specific alloy and wire in use, and the first production run. If any of the figures above sit close to your limits, say so on the quotation request and we will confirm before the order is placed.
