Wie man Lasergrave gekrümmte Oberflächen hat: Ein kompletter Leitfaden mit dem Kommando

Ngrave auf flachen Materialien wie Metall -Tags, Holzbretter, oder Acrylblätter sind unkompliziert. But when it comes to curved surfaces—like rings, Tassen, pipes, or wine bottles—things get a little more complex. Die guten Nachrichten? With the right tools and techniques, du kannst laser engrave cylindrical or curved objects with precision and confidence.

In diesem Ratgeber, we’ll walk you through everything you need to know about laser engraving curved surfaces, from rotary tools to material alignment, plus a deep dive into how ComMarker fiber and UV laser systems make it easier than ever.

Why Curved Surface Engraving Matters

Whether you’re personalizing a wedding ring, branding a stainless steel tumbler, or serializing aerospace parts, curved surfaces are everywhere. Customers increasingly expect custom, high-quality marks—regardless of surface shape.

Common curved items that benefit from laser engraving:

• Schmuck (Ringe, bangles)
• Drinkware (Weinflaschen, Flaschen, Becher)
• Cylindrical metal parts (pipes, fittings)
• Promotional items (Stifte, flashlights)
• Medizinische Geräte und Werkzeuge

The Problem with Curves: Focus and Distortion

Laser engraving relies on maintaining a fixed focal distance between the laser head and the material surface. On a flat surface, this is easy. On a curved surface, Jedoch:

• Der focus point constantly shifts as the curve rises and falls.
• Laser beam distortion can occur, especially on steep curves.
• Text and graphics can warp, if not properly mapped to the surface geometry.

That’s why specialized techniques and tools—like Rotationsbefestigungen—are key.

The Solution: Use a Rotary Axis Attachment

To handle cylindrical or rounded items, the most effective method is to use a rotary axis (or rotary chuck). This accessory rotates the object as the laser fires, keeping the beam at a consistent focus point across the entire circumference.

✅ Compatible with ComMarker Machines:

All ComMarker fiber and UV laser engravers, einschließlich der Omni 1 UV Und Titan 1 JPT MOPA, support rotary axis attachments. They’re plug-and-play with EZCad2 or LightBurn.

Types of rotary attachments:

• Rollendreher: Ideal for cups, Becher, Flaschen, and tubes.
• Chuck Rotary: Perfect for rings, small cylinders, or conical objects.
• Jaw Rotaries: Best for complex or heavy cylindrical parts.

Schritt für Schritt: How to Laser Engrave Curved Surfaces with ComMarker

1. Prepare Your Laser Engraver

• Install your rotary axis and connect it to the appropriate control port.
• Select a lens size that fits your material (z.B., 110×110mm for tight precision).
• Verwenden Lightverburn oder EZCAD2 to switch to rotary mode in settings.

2. Sichern Sie das Material

• Use clamps, jaws, or friction rollers to stabilize the object. Ensure it rotates smoothly.
• For rings, align the inside of the ring perfectly within the focal plane.
• For cups or bottles, level the object to prevent wobble during rotation.

3. Fokussieren Sie den Laser

• Verwenden Autofokus (ComMarker Omni 1) or manually measure and adjust using the electric Z-axis.
• Some ComMarker models offer dual red-light focus pointers to help visualize the beam convergence point.

4. Configure Laser Parameters

This varies based on material and design complexity. Example settings for stainless steel:

Einstellung	Faserlaser (Titan 1 – 30W)	UV-Laser (Omni 1 – 10W)
Leistung	80–100%	50–70%
Geschwindigkeit	200–500 mm/s	100–200 mm/s
Frequenz	20–60 kHz	20–40 kHz
Zeilenintervall	0.02–0,05 mm	0.03–0,05 mm
Pässe	1–3	2–4

✅ Use cross-hatching for high-density artwork.
✅ Enable “Enable Rotary” in LightBurn or EZCad to properly unwrap designs onto the curve.

5. Run a Dry Test

Vor dem Gravieren:

• Benutzen Sie die “frame” or “simulate” option to check pathing.
• Perform a low-power dry run (no beam) to detect misalignment or slip.

6. Beginnen Sie mit der Gravur

Click “Start” and monitor the process. Ensure the object rotates consistently, and the laser remains in focus.

7. Nachbearbeitung

• Wipe down with isopropyl alcohol or mild cleaner to remove debris.
• For metal: consider applying a protective coating (z.B., rust inhibitor).
• Für Glas: verwenden Rust-Oleum white paint prep, then clean with thinner.

Tips for Engraving Specific Curved Materials

Glasbecher

• Verwenden UV-Laser (Omni 1) for clean, cold marking with no cracking.
• Spray surface with white matte paint for better contrast.
• Set speed: 200–300 mm/s, Leistung: 30–40%, Frequenz: 30 kHz.

Metal Rings

• Verwenden Faserlaser (Titan 1 or B6) with chuck rotary.
• Choose a high Q-pulse width (z.B., 200–400ns) for smoother marks.
• Rotate slowly: ~30–50 mm/s.

Wine Bottles

• Rotate via roller rotary.
• Enable split marking with overlap: 0.1mm, split height: 1–3mm.
• Test for center point and start at the logo height.
