标识让机加工件成为可追溯的产品：序列号、批次码、DataMatrix码和二维码、Logo和位置标签，准确落在图纸指定的位置。激光打标在裸金属和阳极氧化表面形成永久、高对比度的标记；UV打印为塑料和经过处理的金属表面添加全彩图文。
两者均可作为机加工的附加工序下单。零件在一次流程中完成加工、表面处理和标识，因此标记落在最终表面上，对比度和位置都正确——而不是落在一个会被后续表面处理改变的表面上。

| 材料 / 牌号 | 常见供货状态 | 切削加工性 | 典型用途 |
|---|---|---|---|
| 铝合金 6061 | T6（固溶处理并时效） | 易切削：切削性能好，切屑控制良好 | 支架、壳体、夹具、从样件到量产的零件 |
| 铝合金 7075 | T6 / T651 | 较难：刀具磨损大，需刚性装夹 | 高强度、重量敏感零件；不适合焊接 |
| 不锈钢 304 / 304L | 退火态 | 加工硬化：需降低切削速度、采用正前角进给 | 一般耐腐蚀场合，食品与过程设备 |
| 不锈钢 316 / 316L | 退火态 | 比304更粘韧：刀具磨损更大 | 氯化物、海洋、医疗和制药环境 |
| 碳钢 1018 / 1045 | 热轧态 / 正火态 | 易至中等；需防锈保护 | 轴类、板类、焊接结构件、工装本体 |

表面处理
退火标记不改变表面尺寸；雕刻标记增加浅层深度，耐搬运磨损。打标相对阳极氧化或电镀的顺序在审图时确认。
| 表面处理 | 作用 | 适用情形 |
|---|---|---|
| 机加工原表面 | 可见刀痕；Ra 通常 1.6-3.2 µm | 零件只需满足功能 |
| 喷砂 | 均匀哑光表面，遮盖刀痕 | 阳极氧化前的外观件 |
| 阳极氧化 II型 | 生成氧化膜；可选颜色 | 铝合金外观并兼有中度防腐与耐磨性 |
| 硬质阳极氧化 III型 | 更厚、更硬的氧化层 | 铝合金滑动面或磨损面 |
| 铬酸盐转化膜 | 薄保护膜，保持导电 | 铝合金电搭接或接地 |
| 化学镀镍 | 均匀、硬度高、耐腐蚀的镀层 | 耐磨加防腐，包括孔内表面 |
| 镀锌 | 经济的牺牲性防腐蚀保护 | 室内或有遮蔽场合的钢件 |
| 粉末喷涂 | 厚实、耐久、装饰性涂层 | 以外观为主要要求时 |
| 钝化处理 | 去除游离铁并恢复氧化膜 | 不锈钢件机加工后 |
| 去应力退火 / 热处理 | 在切削前或切削后消除残余应力 | 必须经受住加工的薄壁和严苛公差零件 |
公差
激光退火和UV打印不增加可测厚度，标记面保持机加工尺寸。雕刻标记较浅（通常0.02–0.1 mm），按图纸指定。
| 图纸标注 | 所需条件 | 对成本和交期的影响 |
|---|---|---|
| 一般公差：±0.25 mm / ±0.010 in | 标准刀具，尺寸抽检 | 基础水平：不加价 |
| 标准公差：±0.13 mm / ±0.005 in | 机床状态良好，首件检验 | 小幅加价；报价的常规默认档 |
| 严苛公差：±0.025 mm / ±0.001 in | 磨制或金刚石刀具，温度控制，三坐标测量 | 台阶式上升：切削更慢且需全检 |
| 精密公差：±0.013 mm / ±0.0005 in | 精加工走刀、量规检具、环境受控 | 加工占价格主导；常作为独立工序 |
| 位置度 / 倾斜度（GD&T） | 基准控制，关联特征尽量一次装夹 | 取决于基准跨越多少次装夹 |
| 表面粗糙度 Ra 0.8 µm 或更优 | 更小的步距、抛光或精加工走刀 | 增加一道工序，而不只是加工时间 |

常见问题
激光打标和激光雕刻，我需要哪一种？
打标（退火）使表面变黑而不去除材料——适用于尺寸不能改变的不锈钢和阳极氧化铝追溯码。雕刻去除浅层材料，标记可经受摩擦和清洁。请告知零件的工作环境，我们会推荐合适的工艺。
能在阳极氧化后的零件上打标吗？
能。本色或黑色阳极氧化面上的深色高对比度标记是标准组合。打标通常在阳极氧化之后进行，以免标记被涂层覆盖；确切顺序在审图时确认。
Logo和UV打印需要什么图稿格式？
矢量图稿（AI、PDF或DXF），并在图纸上注明位置、尺寸和颜色参照。对于DataMatrix码或二维码，请发送数据内容和最小可读尺寸——批量生产前我们会在实际材料上确认可扫读性。
打标会影响零件尺寸吗？
激光退火标记和UV打印不增加可测厚度，公差不受影响。雕刻标记会切削出浅层深度，凡与标记区相交的关键尺寸都会在审图时标注并确认。
What is the minimum order quantity (MOQ)?
Prototypes from 1 pc. Low-volume production typical 50-500 pcs. No forced MOQ on custom parts; unit price drops with volume.
What is the typical lead time?
Industry benchmark: instant-quote platforms deliver prototypes in 1-3 business days. Our own production: prototypes 5-10 working days, including in-house QC and shipping. Production: 2-4 weeks depending on quantity/finishing. Express options exist; finishing adds days.
How do I get a quote and what information do you need?
3D files (STEP/IGS) + 2D drawing with tolerances. Material, quantity, finish, destination country. Quote turnaround: 24-48h typical.
What tolerance should I specify?
Specify tight tolerances only on critical features. Standard ±0.1 mm covers most features. Tighter tolerance = cost multiplier; apply selectively via drawing GD&T.
How is quality controlled?
First-article inspection in our own shop before the first production order. In-process checks. Final inspection report (dimensions) with shipment. Material certs (mill test reports) on request.
Is my design protected?
NDA before file exchange. Files used only for your production. No resale of custom designs.
Which material should I choose?
Function first: strength, weight, corrosion, cost. Common pairings: 6061 general, 304/316 corrosive env., PEEK medical. See materials guide pages.
Which surface finish do I need?
Anodizing for aluminum corrosion/wear/color. Passivation for stainless. Plating for conductivity/steel protection. Cosmetic vs functional distinction.
How do you ship and what terms?
DHL/FedEx/UPS express for samples and small batches. Air/sea freight for production volumes. Incoterms: EXW/FOB/DAP/DDP options.
