ngraving on flat materials like metal tags, wood boards, or acrylic sheets is straightforward. But when it comes to curved surfaces—like rings, 杯子, 管道, or wine bottles—things get a little more complex. The good news? With the right tools and techniques, 你可以 laser engrave cylindrical or curved objects with precision and confidence.
在本指南中, 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:
- 珠宝 (戒指, bangles)
- Drinkware (酒瓶, 烧瓶, 不倒翁)
- Cylindrical metal parts (管道, fittings)
- Promotional items (钢笔, flashlights)
- 医疗设备和工具
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, 然而:
- 这 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 旋转附件—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, 包括 奥姆尼 1 紫外线 和 泰坦 1 JPT莫帕, support rotary axis attachments. They’re plug-and-play with EZCad2 or LightBurn.
Types of rotary attachments:
- 滚筒旋转式: Ideal for cups, 不倒翁, 瓶子, and tubes.
- Chuck Rotary: Perfect for rings, small cylinders, or conical objects.
- Jaw Rotaries: Best for complex or heavy cylindrical parts.
一步一步: 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 (例如, 110×110mm for tight precision).
- 使用 Lightburn或EZCAD2 to switch to rotary mode in settings.
2. 确保材料安全
- 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. 聚焦激光
- 使用 自动对焦 (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:
环境 | 光纤激光器 (泰坦 1 – 30瓦) | 紫外激光 (奥姆尼 1 – 10瓦) |
---|---|---|
力量 | 80–100% | 50–70% |
速度 | 200–500 mm/s | 100–200 mm/s |
频率 | 20–60 kHz | 20–40 kHz |
行距 | 0.02–0.05毫米 | 0.03–0.05毫米 |
通行证 | 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
雕刻前:
- 使用 “frame” or “simulate” option to check pathing.
- Perform a low-power dry run (no beam) to detect misalignment or slip.
6. 开始雕刻
Click “Start” and monitor the process. Ensure the object rotates consistently, and the laser remains in focus.
7. 后期处理
- Wipe down with isopropyl alcohol or mild cleaner to remove debris.
- 对于金属: consider applying a protective coating (例如, rust inhibitor).
- 玻璃用: 使用 Rust-Oleum white paint prep, then clean with thinner.
Tips for Engraving Specific Curved Materials
玻璃杯
- 使用 紫外激光 (奥姆尼 1) 要干净, cold marking with no cracking.
- Spray surface with white matte paint for better contrast.
- Set speed: 200–300 mm/s, 力量: 30–40%, 频率: 30 千赫.
Metal Rings
- 使用 光纤激光器 (泰坦 1 或B6) with chuck rotary.
- Choose a high Q-pulse width (例如, 200–400ns) for smoother marks.
- Rotate slowly: ~30–50 mm/s.
Wine Bottles
- Rotate via roller rotary.
- Enable split marking with overlap: 0.1毫米, split height: 1–3mm.
- Test for center point and start at the logo height.
