Como fazer superfícies curvas de gravação a laser: Um guia completo com Commarker

cura em materiais planos como etiquetas de metal, Placas de madeira, ou folhas de acrílico são diretas. But when it comes to curved surfaces—like rings, xícaras, pipes, or wine bottles—things get a little more complex. A boa notícia? With the right tools and techniques, você pode laser engrave cylindrical or curved objects with precision and confidence.

Neste guia, 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:

• Joia (argolas, bangles)
• Drinkware (garrafas de vinho, frascos, copos)
• Cylindrical metal parts (pipes, fittings)
• Promotional items (canetas, flashlights)
• Dispositivos e ferramentas médicas

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, no entanto:

• O 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 Acessórios rotativos—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, including the Omni 1 ultravioleta e Titã 1 JPT MOPA, support rotary axis attachments. They’re plug-and-play with EZCad2 or LightBurn.

Types of rotary attachments:

• Rolo Rotativo: Ideal for cups, copos, garrafas, and tubes.
• Chuck Rotary: Perfect for rings, small cylinders, or conical objects.
• Jaw Rotaries: Best for complex or heavy cylindrical parts.

Passo a passo: 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 (por exemplo, 110×110mm for tight precision).
• Usar LightBurn or EZCad2 to switch to rotary mode in settings.

2. Proteja o 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. Concentre o laser

• Usar auto-focus (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:

Contexto	Laser de fibra (Titã 1 – 30C)	Laser UV (Omni 1 – 10C)
Poder	80–100%	50–70%
Velocidade	200–500 mm/s	100–200 mm/s
Frequência	20–60 kHz	20–40 kHz
Intervalo de linha	0.02–0.05 mm	0.03–0.05 mm
Passes	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

Antes de gravar:

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

6. Comece a gravar

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

7. Pós-processamento

• Wipe down with isopropyl alcohol or mild cleaner to remove debris.
• Para metais: consider applying a protective coating (por exemplo, rust inhibitor).
• Para vidro: usar Rust-Oleum white paint prep, then clean with thinner.

Tips for Engraving Specific Curved Materials

Copos de vidro

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

Metal Rings

• Usar laser de fibra (Titã 1 or B6) with chuck rotary.
• Choose a high Q-pulse width (por exemplo, 200–400ns) for smoother marks.
• Rotate slowly: ~30–50 mm/s.

Wine Bottles

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