一、从「源头」减少粉尘（最有效） ✅ 1️⃣ 选对切割方式（优先级很高） | 切割方式 | 粉尘量 | 说明 | | ------------- | --------- | --------------- | | 冷切锯 / 带锯 | ⭐ 最少 | 切屑是颗粒/条状 | | 手锯（钢锯） | ⭐⭐ 少 | 粉尘不飞 | | 角磨机切割片 | ❌ 多 | 高速产生细粉 | | 砂轮切割 | ❌❌ 非常多 | 粉尘 + 火花 |
easy for cutting
| Material | Relative Cutting Ease | Tool Wear | Dust / Chips Produced | Heat Generation | Notes |
|---|---|---|---|---|---|
| Aluminum Alloy | ⭐⭐⭐⭐⭐ (Very Easy) | Low | Chips (few fine dust) | Low–Medium | Soft, cuts easily; may clog blades if RPM too high |
| Brass (黄铜) | ⭐⭐⭐⭐☆ (Easy) | Low–Medium | Clean chips | Medium | Free-cutting, stable; less grabbing than aluminum |
| Copper (紫铜) | ⭐⭐⭐☆☆ (Medium) | Medium | Long, sticky chips | Medium–High | Very ductile; tends to smear and stick to tools |
| Stainless Steel | ⭐⭐☆☆☆ (Hard) | High | Fine chips + dust | High | Tough, work-hardens; needs low speed and coolant |
