Wrist watch
Engraving and marking a wrist watch with a Speedy flexx
We show you how you can laser engrave and mark materials in one step.
Preparation
Required material:
- Wristwatch with stainless steel case
- Lego to position the items in the machine
Machine used:
- Speedy 360 flexx
- 80 Watt CO2
- 30 W fiber laser
- 2.85" lens
- vacuum table
This sample can be produced with any machine from the flexx laser engraver series.
Step by Step
Step 1: Design
Import our template or create your own design. Adapt the design so to the shape of the watch. Measure the height difference between the materials. This figure is required for the z-offset (for the watch we used there is no height difference between metal and leather). Why this step is so important and other helpful hints about how to use flexx technology is explained here.
Send the job to the laser using the following printer driver settings:
| Process mode | Resolution | Cut line | Halftone | Others |
|---|---|---|---|---|
| Standard | 1000 dpi | none | Color | - |
Tip:
It is easier to position/adjust the design, if you send the graphic elements for housing and wristband separately. By doing this you can position the graphics precisely with the help of the laser pointer.
Step 2: Laser process
Make the parameter settings. The parameters can differ depending on the laser machine used and laser power available.
Important: When engraving a flexx job, always focus on the metal resp. on the material that shall be processed with the fiber laser.
Laser Parameters Annealing:
| Color | Process | Power (%) | Speed (%) | ppi/Hz |
|---|---|---|---|---|
| Black | Engraving FLP | 85 | 3 | 30000 |
| Passes | Air Assist | Z-Offset | Advanced |
|---|---|---|---|
| 1 | on | +2 mm | - |
Laser Parameters Engraving:
| Color | Process | Power (%) | Speed (%) | ppi/Hz |
|---|---|---|---|---|
| Red | Engraving CO2 | 15 | 15 | 1000 |
| Passes | Air Assist | Z-Offset | Advanced |
|---|---|---|---|
| 1 | on | - | - |
Step 3: Post-processing
No post-processing is necessary. Due to the annealing process, the metal surface is not damaged which makes the watch comfortable to wear.
