提问
切8mm碳钢用哪种激光切割机？

豆包大模型的回答

切割8mm 碳钢，优先选择光纤激光切割机，这是目前金属板材切割的主流设备，相比传统 CO₂激光切割机，具有能量利用率高、切割速度快、运行成本低的优势。以下是具体的选型方案和技术要点：
一、核心选型参数
激光器功率这是切割 8mm 碳钢的核心指标，功率直接决定切割效率和质量：
最低功率门槛：2000W
2000W 光纤激光可实现 8mm 碳钢的稳定切割，搭配氧气辅助切割时，切割速度约 1.5–3m/min，适合中小批量加工场景。
推荐功率：3000W
3000W 功率下，切割速度可提升至 3–5m/min，同时切割断面的垂直度和光滑度更好，能减少后续打磨工序，更适合批量生产或对切割质量要求较高的工况。
若需兼顾 10–12mm 碳钢切割，可直接选 4000W 及以上功率机型，避免后续设备升级成本。
辅助气体选择碳钢激光切割的辅助气体分两种，需根据需求选择：
氧气切割（主流方案）
原理：氧气与高温碳钢发生放热氧化反应，辅助激光熔化材料，同时吹走熔渣。
优势：成本低、切割速度快，适合对断面氧化层不敏感的结构件。
参数：气体压力控制在 0.3–0.5MPa，纯度≥99.5%。
氮气切割（无氧化切割）
原理：氮气作为惰性气体，仅起到吹走熔渣的作用，不参与化学反应。
优势：切割断面无氧化层，光洁度高（Ra≤12.5μm），无需二次除锈，适合对表面质量要求高的零部件。
劣势：成本高（氮气消耗量大于氧气）、切割速度比同功率氧气切割慢约 30%。

切8mm碳钢，现在优先推荐：光纤激光切割机，一般选1000–1500W这一档，再配一个交换台（双工位），性价比最高。
如果偶尔切、质量要求不极致：800W光纤也能切，但速度慢、参数要精细调。
CO2激光也可以切，但电耗和维护高，现在新项目基本不作为首选。

如果切割量不大、对速度不敏感，1000W-1500W的机型初期投资更低。如果追求高效生产，3000W以上机型能大幅缩短切割时间，长期看更经济。

To cut **8mm carbon steel** effectively, the industry standard and most recommended option is a **Fiber Laser Cutting Machine** with a power rating between **1.5kW (1500W) and 3kW (3000W)**.
While a 1kW machine can technically "bite" through 8mm steel, it often produces a rougher edge and operates at speeds too slow for production. For a balance of speed, edge quality, and cost, the **2kW to 3kW range** is considered the "sweet spot."
### 1. Recommended Machine Type: Fiber Laser
Fiber lasers are superior to lasers for this specific application because they have a shorter wavelength that is more efficiently absorbed by carbon steel.
* **Efficiency:** Fiber lasers have 3–5 times higher wall-plug efficiency than .
* **Maintenance:** No mirrors to align and no gas required for the resonator (the laser source itself is solid-state).
* **Speed:** On 8mm steel, a fiber laser is significantly faster than a laser of equivalent power.
### 2. Power Options & Performance
The choice of wattage determines your "cutting throughput" and the quality of the finish.
| Laser Power | Cutting Speed (Approx.) | Edge Quality | Verdict |
| --- | --- | --- | --- |
| **1.5kW** | 1.1 – 1.3 m/min | Moderate slag; slower pierce | Entry-level for 8mm. |
| **2.0kW** | 1.4 – 1.8 m/min | Cleaner edge; faster pierce | **Highly Recommended** for small shops. |
| **3.0kW** | 1.8 – 2.5 m/min | Smooth, "bright" finish possible | **Best for Production** and thickest versatility. |
### 3. Key Technical Considerations
* **Assist Gas:** * **Oxygen ():** Most common for carbon steel. It creates an exothermic reaction that helps melt the metal, allowing for faster speeds. However, it leaves a thin oxide layer that must be removed if you plan to paint or powder coat.
* **Nitrogen ():** Used for "bright cutting" or oxide-free edges. It requires higher power (usually **3kW+**) and significantly higher gas pressure, increasing operating costs.
* **Nozzle Choice:** Use a **Double-Layer Nozzle** (typically 1.4mm to 2.0mm diameter). The double-layer design helps stabilize the oxygen flow, which is crucial for preventing "burning" or dross on 8mm plate.
* **Focus Position:** For 8mm carbon steel, the focus is typically set slightly **inside/below** the material surface (e.g., to ) to ensure the energy penetrates the full thickness of the plate.
### 4. Machine Features to Look For
* **Auto-Focus Cutting Head:** Essential for thick plates to ensure the pierce and the cut are handled at different heights automatically.
* **Heavy-Duty Frame:** Ensure the machine bed is heat-treated or plate-welded. Cutting 8mm steel consistently generates significant heat and vibration; a lightweight "advertising-grade" frame will warp over time.
* **FSCUT or CypCut Controller:** These are the industry standards for fiber lasers and offer pre-set "parameter libraries" for 8mm steel, making setup much easier.

有公司采购如果想查询切8mm碳钢的激光切割机的信息，过去用搜索，现在就咨询各家大模型。
因为年初deepseek引爆了低成本大模型的浪潮，那么他选择了deepseek。
智谱大模型作为国产大模型第1股，也引起了他的兴趣。
因担心问一个国产大模型不准，所以他选择同时向这两家咨询。
然后这两家从上面的结果看，都推荐1000~1500kw。
所以你觉得这家伙会怎么办？会不会真就选1000~1500kw？
