ngraving on flat materials like metal tags, wood boards, or acrylic sheets is straightforward. But when it comes to curved surfaces—like rings, カップ, pipes, or wine bottles—things get a little more complex. The good news? With the right tools and techniques, あなたはできる laser engrave cylindrical or curved objects with precision and confidence.
このガイドでは, 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:
- ジュエリー (指輪, bangles)
- Drinkware (ワインボトル, フラスコ, タンブラー)
- Cylindrical metal parts (pipes, fittings)
- Promotional items (ペン, flashlights)
- Medical devices and tools
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, しかし:
- の 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 ロータリーアタッチメント—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 オムニ 1 紫外線 そして タイタン 1 JPT MOPA, support rotary axis attachments. They’re plug-and-play with EZCad2 or LightBurn.
Types of rotary attachments:
- ローラーロータリー: Ideal for cups, タンブラー, ボトル, and tubes.
- Chuck Rotary: Perfect for rings, small cylinders, or conical objects.
- Jaw Rotaries: Best for complex or heavy cylindrical parts.
ステップバイステップ: 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 (例えば, 110×110mm for tight precision).
- 使用 LightburnまたはEZCAD2 to switch to rotary mode in settings.
2. 材料を確保する
- 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. レーザーの焦点を合わせる
- 使用 オートフォーカス (コムマーカーオムニ 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:
| 設定 | ファイバーレーザー (タイタン 1 – 30W) | UVレーザー (オムニ 1 – 10W) |
|---|---|---|
| 力 | 80–100％ | 50–70% |
| スピード | 200–500 mm/s | 100–200 mm/s |
| 頻度 | 20–60 kHz | 20–40 kHz |
| ライン間隔 | 0.02–0.05 mm | 0.03–0.05 mm |
| パス | 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
彫刻前:
- を使用します “frame” or “simulate” option to check pathing.
- Perform a low-power dry run (no beam) to detect misalignment or slip.
6. 彫刻を開始する
Click “Start” and monitor the process. Ensure the object rotates consistently, and the laser remains in focus.
7. 後処理
- Wipe down with isopropyl alcohol or mild cleaner to remove debris.
- For metal: consider applying a protective coating (例えば, rust inhibitor).
- ガラス用: 使用 Rust-Oleum white paint prep, then clean with thinner.
Tips for Engraving Specific Curved Materials
ガラスタンブラー
- 使用 UVレーザー (オムニ 1) for clean, cold marking with no cracking.
- Spray surface with white matte paint for better contrast.
- Set speed: 200–300 mm/s, 力: 30–40%, 頻度: 30 kHz.
Metal Rings
- 使用 ファイバーレーザー (タイタン 1 or B6) with chuck rotary.
- Choose a high Q-pulse width (例えば, 200–400ns) for smoother marks.
- Rotate slowly: ~30–50 mm/s.
Wine Bottles
- Rotate via roller rotary.
- Enable split marking with overlap: 0.1んん, split height: 1–3mm.
- Test for center point and start at the logo height.
