CNC 加工外贸销售话术 SOP

CNC 是"图纸驱动"的生意，客户最关心的是——你能不能读懂图、公差稳不稳、交期靠谱不靠谱。开发信第一封不要卖工厂多大、多少设备，要卖"我懂你的痛点"。用一句具体的公差/材料痛点做钩子，让他觉得你不是群发。

Subject: Tight-tolerance aluminum parts — 48h quote, IT7 held in-house Hi {First Name}, Saw your team is scaling up the {product line, e.g. drone gimbal} at {Company}. If you're still sending your ±0.01 mm 7075-T6 parts to multiple shops for quotes, we can probably shorten that loop. We're a 5-axis CNC shop in Dongguan, running 22 Brother/Mazak machines, ISO 9001 + AS9100 in progress. We hold IT7 in-house without outsourcing, and our average RFQ turnaround is **under 48 hours** with a full DFM feedback sheet — not just a number. Would it be useful if I quoted one of your current parts as a benchmark? Just drop a STEP + PDF and I'll come back with price, lead time, and 2–3 DFM suggestions. Best, {Your Name} | {Company} | WeChat/WhatsApp: {xxx}

主题：紧公差铝件——48 小时报价，IT7 级公差厂内可控 {名字} 您好， 看到贵司在扩产 {产品线，如无人机云台}。如果您目前还在把 ±0.01mm 的 7075-T6 铝件分给多家厂对比报价，我们也许能帮您把这个流程缩短。 我们是东莞一家 5 轴 CNC 加工厂，22 台 Brother/Mazak 设备，ISO 9001 已认证，AS9100 认证进行中。IT7 级公差完全厂内加工不外协，RFQ 平均**48 小时内**回复，并附完整 DFM 反馈表，而不仅仅是一个报价数字。 方便发我一个您现有的图纸做基准报价对比吗？发 STEP + PDF 即可，我会给到价格、交期以及 2–3 条 DFM 优化建议。

不要立刻蒙头报价。先确认关键信息（材料牌号、热处理、表面处理、公差基准、数量阶梯、目标市场），一是确保报价准确，二是显示专业度，三是"询问"本身就是一次接触。

Hi {Name}, Thanks for the RFQ — files received (P/N XX-001, Rev A). Before I release the quote, could you confirm the following so my numbers are locked, not indicative? 1. **Material spec**: 6061-T6 or 6082-T6? Any mill cert (EN 10204 3.1) required? 2. **Surface finish**: Type II clear anodize, or Type III hard anodize? Any masking on the threaded holes? 3. **Critical tolerances**: The Ø10 H7 bore — is this the mating datum? Do we need CMM reports on every piece or AQL sampling? 4. **Quantities**: Please share 3 price-break qty (e.g. 50 / 200 / 1,000 pcs) so I can show you the best tier. 5. **End market**: Is this for a medical or aerospace end use? It affects the QC package we build in. 6. **Target lead time & Incoterm**: EXW / FOB Shenzhen / DDP door? I'll turn the quote around within 24 hours of your reply, with a DFM note if I see anything worth flagging. Regards, {Your Name}

{名字} 您好， 感谢询盘，图纸已收到（图号 XX-001，Rev A）。 报价前烦请确认以下信息，以便报价可直接落单，不留模糊空间： 1. **材料**：6061-T6 还是 6082-T6？是否需要 EN 10204 3.1 材质证书？ 2. **表面处理**：普通阳极氧化（Type II）还是硬质阳极氧化（Type III）？螺纹孔是否需要遮蔽？ 3. **关键公差**：Ø10 H7 孔是否为配合基准？是否需要每件 CMM 检测报告，还是 AQL 抽样即可？ 4. **数量**：请给 3 档数量（如 50 / 200 / 1000 pcs），方便匹配最优阶梯价。 5. **终端用途**：医疗还是航空领域？会影响我们配置的品质文件。 6. **目标交期与贸易条款**：EXW / FOB 深圳 / DDP 到门？ 收到您回复后 24 小时内出正式报价，若有可优化点会一并附 DFM 建议。

不要让客户觉得"你麻烦"，要让他觉得"你专业"。主动帮他把 2D 转 3D 通常没问题，但要把"我们帮您做了什么"讲清楚，为后续报价溢价埋伏笔。

Hi {Name}, Got your 2D sketch — thanks for trusting us with an early concept. We can absolutely quote from a 2D, but to make sure we're pricing the *right* part I'll do this: 1. Build a 3D model from your sketch (free of charge, ~4 hours). 2. Send it back for your sign-off before we cut any metal. 3. Flag any features that are hard to machine or drive up cost — often we can save 10–20% by tweaking a corner radius or a wall thickness. Could you confirm the material, quantity, and whether this is a functional part or an early prototype? I'll get the model + quote to you by {day}. Best, {Your Name}

{名字} 您好， 收到您的 2D 手绘图，感谢在早期阶段就把项目分享给我们。 我们完全可以根据 2D 图报价，为了保证报的是"对的那个零件"，我建议这样做： 1. 我们免费根据您的手绘图建 3D 模型（约 4 小时）。 2. 建好后先发您确认，确认无误再开料。 3. 帮您指出难加工/贵成本的特征，通常调整一个倒角或壁厚就能省 10–20%。 麻烦确认下材料、数量、以及这是功能件还是早期原型？我最迟 {日期} 前把 3D 图 + 报价一并给您。

CNC 老外工程师最讨厌两种回复——"这个我们做不了"、"按图做没问题"。前者显得没能力，后者出问题背锅。正确姿势：**指出问题 → 给两个方案 → 让客户选**。

Hi {Name}, Doing a DFM pass on drawing XX-002, and I want to flag one item before we quote: **Issue**: Note 3 calls out surface roughness Ra 0.4 on the Ø8 bore, but the position tolerance is ⌀0.05 M relative to |A|B|C|. Holding Ra 0.4 on that bore in 316L usually requires an ID grinding pass, which adds ~$3.50/pc and 3 days lead time. **Two options**: - **Option A** (as-drawn): Ra 0.4 held by ID grind. Price ↑ ~$3.50/pc, lead time 15 days. - **Option B** (recommended): Loosen to Ra 0.8, achievable by a finish boring pass. Price stays baseline, lead time 10 days. In our experience this still gives a leak-tight fit on standard O-rings. Could you check with your design engineer which route works? I'll quote both once you decide, so you have flexibility. Regards, {Your Name}

{名字} 您好， 我在做图纸 XX-002 的 DFM 评审，报价前想先跟您确认一点： **问题**：Note 3 要求 Ø8 内孔 Ra 0.4，但位置度是 ⌀0.05 M 基于 |A|B|C|。316L 材料要在此孔上保持 Ra 0.4 通常需要内孔磨削工序，会增加约 $3.50/件、交期延长 3 天。 **两个方案**： - **方案 A**（按图）：Ra 0.4，需内磨。单价 +$3.50，交期 15 天。 - **方案 B**（推荐）：放宽至 Ra 0.8，精镗即可达到。价格不变，交期 10 天。我们经验中该表面仍可与标准 O 型圈密封。 麻烦您跟设计工程师确认走哪个方案，两个方案我都可以报，供您决策。

老外买 CNC 不是买"最低价"，是买"确定性"。报价邮件正文要主动做三件事：**总结价、锁定条件、给出下一步动作**。避免只发一个 PDF 附件就完事。

Subject: Quotation Q26-0715-01 | P/N XX-001 | Ready for your review Hi {Name}, Quotation attached. Quick summary so you don't have to open the PDF unless needed: | Qty | Unit Price (USD) | Lead Time | |---|---|---| | 50 pcs | $12.80 | 12 working days | | 200 pcs | $9.40 | 15 working days | | 1,000 pcs | $7.20 | 22 working days | - **Terms**: FOB Shenzhen, USD, valid 30 days - **Payment**: 30% T/T deposit, 70% before shipment (negotiable at 500+ pcs) - **Included**: Material cert (3.1), FAI report (ISO 2768-m), full dimensional report on 1st article - **DFM note**: On feature "Slot 2" I've suggested a 0.5 mm relief that saves ~7% at 1K pcs — highlighted in yellow on the marked-up PDF (page 2) If the numbers work directionally, I'd suggest we lock a small sample run (5–10 pcs) so your engineer can validate fit before you commit to full qty. Sample cost is credited back on the PO. What's your target project start date? Happy to hold a machine slot if timing is tight. Best, {Your Name}

主题：报价单 Q26-0715-01 | 图号 XX-001 | 请查收 {名字} 您好， 报价单见附件。以下是快速摘要，您不必打开 PDF： | 数量 | 单价 (USD) | 交期 | |---|---|---| | 50 pcs | $12.80 | 12 工作日 | | 200 pcs | $9.40 | 15 工作日 | | 1000 pcs | $7.20 | 22 工作日 | - **条款**：FOB 深圳，美元，30 天有效 - **付款**：30% 定金，70% 发货前付清（500 件以上可谈） - **含**：3.1 材质证明，首件 FAI 报告（ISO 2768-m），全尺寸报告 - **DFM 建议**：Slot 2 处建议加 0.5mm 让位，1K 量可省约 7%，已在附件 PDF 第 2 页黄标示出 如价格方向可接受，建议先小批打样 5–10 件，让您的工程师先验证配合，样品费下单时抵扣。 请问您项目计划启动时间？如时间紧，我可先帮您预留机台档期。

**永远不要直接降价**。先反问，把"贵"这个模糊词具象化——是比别家贵？比预算贵？比去年贵？不同答案对应不同策略。

Hi {Name}, Appreciate the direct feedback — that's the fastest way for us to find a fit. Just so I can respond meaningfully: when you say "too high", is it against - **(a)** another quote you have in hand (mind sharing the delta %? no need to disclose the supplier), - **(b)** the internal target/BOM budget for this project, or - **(c)** last year's price on a similar part? Reason I ask: if it's (a), 9 times out of 10 the other quote is on a different spec — different material lot, no cert, no FAI, or offshore anodize. Once we align spec, the gap usually closes. If it's (b) or (c), I can walk you through 2–3 concrete levers (qty consolidation, material substitution, tolerance relaxation on non-critical features) that we've used to hit target on similar programs. Which one is it? Best, {Your Name}

{名字} 您好， 感谢直接反馈，这样我们最容易对上节奏。 为方便有针对性回应，您说"贵"是指： - **(a)** 对比另一份报价（可否分享差多少百分比？不需要告知供应商） - **(b)** 超出您项目的内部预算/BOM - **(c)** 高于去年类似零件的价格 因为：如果是 (a)，十次里九次是规格不同——不同批次料、无证书、无 FAI、或阳极氧化外协。规格对齐后差距通常收窄。如果是 (b) 或 (c)，我可以给您 2–3 个具体的降本抓手（合并数量、材料替换、非关键面公差放宽），我们在类似项目上帮客户达标过。 请问是哪种情况？

样品邮件是"预设期望"的关键节点。要主动告知客户：**样品做了什么、检了什么、你要看什么、有偏差怎么处理**。避免客户拿到样品后自己解读，导致误会。

Hi {Name}, Sample tracking: DHL 12345678, ETA {date}. What's in the box: - 5 pcs of P/N XX-001, machined per Rev A - FAI report (all 24 dimensions measured on Zeiss CMM) - Material cert 3.1 for the 6061-T6 stock - Two "witness" pieces cut from the same bar, in case you want to run destructive tests Two things I'd like you to check first: 1. The Ø10 H7 bore — please gauge with your mating pin, tolerance was held at 10.008–10.014. 2. Anodize color — we ran a standard clear (Type II class 1). If your product needs a specific pantone, we can dye-match on the next batch. One heads-up: on pcs #3 the anodize shows a very faint rack mark near the M4 hole (~0.2 mm). Cosmetic only, no dimensional impact. We'll mask that area on production if you want it invisible. Once you've had 2–3 days with the parts, could we book a 20-min call to walk through your findings? I'd rather catch any concern now than after 1,000 pcs. Regards, {Your Name}

{名字} 您好， 样品追踪号：DHL 12345678，预计 {日期} 送达。 包裹内容： - 图号 XX-001，5 件，按 Rev A 加工 - FAI 首件报告（Zeiss 三坐标全 24 尺寸检测） - 6061-T6 原材 3.1 材质证明 - 同批 2 件"陪试件"，如您需破坏性测试可用 请重点确认两点： 1. Ø10 H7 孔，请用您的配合销规检验，我们控制在 10.008–10.014。 2. 阳极氧化颜色，本次是标准本色 II 型 1 级，如需特定 Pantone 色号，量产可染色匹配。 提前说明：#3 件在 M4 孔附近有一处极淡的挂具痕（约 0.2mm），仅外观，不影响尺寸。量产可对该区域遮蔽处理，如您在意外观。 建议您使用样品 2–3 天后，我们约 20 分钟视频对样品做过一遍，量产前发现任何问题都比 1000 件后再改要好。

不要一口拒绝，也不要一口答应。**用"分阶段建立信任"来置换账期**。第一单严格，第三单起可谈账期，中间给出明确路径感。

Hi {Name}, Fully understand — Net 30 is standard for you, and I'd want the same in your position. Here's how we typically get there with new accounts, so you're not stuck paying deposits forever: - **Order 1–2**: 30/70 T/T (deposit + balance before shipment). This gets us both comfortable on quality and delivery. - **Order 3 onwards**: We can move to **30% T/T + 70% Net 30** against B/L, up to a credit line of USD 30,000. - **After 6 months / 3 clean orders**: Open Net 30 up to USD 60,000, subject to a Sinosure credit check on {Company} (we cover the fee). Alternatively, if this first PO is time-sensitive and you'd like Net 30 immediately, we can price in a **1.5% financing fee** — which is basically our cost from Sinosure/factoring. Fully transparent, your call. Which route works better for you? Best, {Your Name}

{名字} 您好， 完全理解，Net 30 是您标准条款，换我在您位置也会这么要求。 我们通常这样跟新客户逐步建立账期，让您不至于永远付定金： - **第 1–2 单**：30/70 电汇（定金 + 发货前尾款），双方对品质交期先建立信心。 - **第 3 单起**：可升级为 **30% 定金 + 70% Net 30 见提单**，信用额度上限 3 万美元。 - **半年 / 3 单无违约后**：可升至 Net 30 / 6 万美元额度，需对 {公司名} 做中信保信用审核（费用我方承担）。 或者如果本单确实很紧，希望立刻 Net 30，我可以在报价里加 **1.5% 融资费**——这基本是我们的中信保/保理成本，完全透明，由您选。 您倾向哪种？

CNC 客户最怕"人间蒸发"。主动周报 = 免费的信任积分。哪怕没进展也要发——"本周排产未变"也是一种消息。

Subject: [Weekly Update W28] PO 26-0715 | On track for ship 8/12 Hi {Name}, Weekly status on your PO: | Stage | Status | Note | |---|---|---| | Raw material | ✅ Done (7/16) | 6061-T6, cert on file | | Rough machining | ✅ Done (7/19) | 200/200 pcs | | Finish machining | 🟡 In progress (145/200) | Completion 7/23 | | Deburr + tumbling | ⏳ Scheduled 7/24 | | | Anodize (outsourced) | ⏳ Scheduled 7/25–7/29 | Type II clear | | Final QC + pack | ⏳ Scheduled 7/30 | Full dim on 5% AQL | | Ship | 🎯 Target 8/12 | FOB Shenzhen | Nothing flagged, on track.

**坏消息越早说越好**。老外最恨的不是延误，是"到期那天才告诉他"。主动、有方案、有补偿姿态。

Hi {Name}, Straight to the point: your PO 26-0715 will slip by ~4 working days. New ship date is **8/18** instead of 8/12. **What happened**: The anodize vendor had a bath contamination on 7/26 that affected 3 lots including yours. Parts are safe (dimensionally OK), but color batch failed our QC and we're re-running. **What I've done**: - Moved your parts to the front of the queue at a backup anodizer (already confirmed capacity). - Upgraded shipment from ocean to **air freight at our cost** — that recovers 12 days vs. the original sea plan, so you'll actually receive them **6 days earlier than the original ETA at your DC**. - Attached is the revised schedule and the anodize vendor's containment report. Apologies for the noise. What's the best channel for you if I need to reach you same-day going forward — email or WhatsApp? Best, {Your Name}

{名字} 您好， 直接说：您的 PO 26-0715 会延误约 4 个工作日，新出货日 **8/18**（原 8/12）。 **原因**：氧化外协厂 7/26 药水槽污染，影响 3 批含我们这批。零件尺寸没问题，但颜色批次不过我们内检，重新氧化。 **我已经做的**： - 已把您的货切换到备用氧化厂并排在最前，产能已确认。 - 出货方式从海运升级为 **空运，费用我方承担**，比原海运计划提前 12 天，实际到您 DC **比原 ETA 早 6 天**。 - 附件是新排期和氧化厂的问题分析报告。 打扰您了。以后如遇当日紧急事项，您更希望我用邮件还是 WhatsApp 联系？

不管对错，先"接住情绪 + 认真对待"。**流程：致歉 → 请求证据 → 独立复检 → 根因分析 → 补偿方案 → 长效动作**。不要在没数据时说"我们厂内检没问题"，那是最激怒客户的话。

Hi {Name}, Thanks for flagging this immediately — that's the right call, and I take it seriously. Before I speculate, could I ask for: 1. Photos of the 3 rejected pcs (including serial number if marked) 2. Your measurement method + tool used (caliper, CMM, gauge) 3. The actual reading vs. print callout In parallel, I'm pulling the retained samples from your batch here and having our QA remeasure on our Zeiss CMM this afternoon. I'll share our data by tomorrow EOD your time, and we can compare. **Regardless of root cause**, here's what I'll commit to right now: - Replacement of the 3 pcs, air-freighted at our cost, target arrival within 5 days. - If root cause is on our side, we'll issue an 8D report within 7 days and add {containment action} to our control plan. - If root cause turns out to be measurement/handling, no charge — we'll still send replacements as goodwill, and we can jointly review the inspection SOP so this doesn't repeat. Fair? Best, {Your Name}

{名字} 您好， 感谢第一时间反馈，这是正确的做法，我非常重视。 在做任何判断前，可否请您提供： 1. 3 件不良的照片（如有序号请一并提供） 2. 您的检测方法及量具（卡尺 / CMM / 塞规） 3. 实测值 vs. 图纸要求 同步我今天下午会调这批的留样，让 QA 用我们的 Zeiss 三坐标复测，明晚您时间前把我方数据发给您对比。 **不论根因归属，我现在先承诺**： - 3 件补货，空运费用我承担，5 天内到货为目标。 - 若根因在我方，7 天内出 8D 报告，并将 {控制措施} 加入我们的控制计划。 - 若最终判定为检测/搬运问题，仍免费补货作为诚意，另可一起复盘检验 SOP 避免重复。 这样安排您觉得公平吗？

不要问 "Do you have any new order?"，太乞讨。要给他一个**具体的、对他有价值的**理由回你消息。

Hi {Name}, Been a couple of months — hope {product / project} is doing well in the field. Two updates on our side that might be relevant for you: 1. We just brought in-house **wire EDM** (Sodick AG400L), so if you had any parts you were splitting between us and an EDM shop, we can consolidate now — usually saves 5–8 days on lead time. 2. Our 6061-T6 material cost dropped ~6% in Q3 vs. Q2 (spot market). If you have any repeat parts, worth me re-quoting — could translate to a small credit on your next PO. No pressure at all — just wanted to keep you in the loop. If there's a re-order or a new drawing in the pipeline, happy to prioritize a slot. Best, {Your Name}

{名字} 您好， 有段时间没联络了，{产品/项目} 在现场运行得还顺利吧？ 我方有两个可能对您有价值的更新： 1. 我们新增了厂内**线切割**（Sodick AG400L），如果您之前有零件在我们和线切割厂之间拆分加工，现在可以合并到我们厂，通常能省 5–8 天交期。 2. Q3 现货市场 6061-T6 材料成本较 Q2 下降约 6%，若您有重复件，值得我重新报一次，可能在下单时抵扣一部分。 不着急下单，只是让您了解一下。如果近期有返单或新图纸，我可以优先给您排机台。

CNC 展会最大问题是"厂家太多，长得都一样"。用**1 个数字 + 1 个客户案例 + 1 个反差** 让对方 30 秒内记住你。

Hi, I'm {Name} from {Company}. We're a Dongguan-based 5-axis CNC shop — but the reason people usually stop is this: our RFQ-to-quote average is 18 hours, not 3 days. We hold IT7 in-house so we don't lose a week outsourcing. Last year we shipped 240,000 pcs to a German medical robotics customer with zero PPM. Are you sourcing precision metal parts, or is your focus more on prototypes?

您好，我是 {公司} 的 {名字}。我们是东莞的一家 5 轴 CNC 加工厂，通常客户驻足的原因是这个数字——我们 RFQ 到报价平均 18 小时，不是 3 天。IT7 级公差厂内完成，不会因外协多花一周。去年给一家德国医疗机器人客户出了 24 万件，PPM 为 0。您目前是采购精密金属件，还是主要做原型？

不要说 "Just following up"（老外看到就烦）。用**新信息**或**新问题**制造回复必要性。

Hi {Name}, Quick note on quote Q26-0715-01: I was reviewing the drawing again and noticed we can drop the price by ~4% at 1K pcs if we run 4-up instead of 2-up on our pallet — no spec change, just tooling layout. Want me to send a revised sheet? Also, if the project has shifted timing, no problem — just let me know so I can adjust our capacity plan. Best, {Your Name}

{名字} 您好， 关于报价 Q26-0715-01 补充一点：我又看了一遍图，1K 量在我们卡盘上从 2 联做改成 4 联做，可以再降约 4%，规格不变，纯排版优化。 需要我发一份修订版吗？另外如项目时间有推迟也没关系，麻烦告知一下，方便我调整产能安排。

**优雅退出**比"死缠烂打"更有效。老外会记得那些"知进退"的销售，几个月后自然回来找你。

Hi {Name}, Haven't heard back on Q26-0715-01, so I'll assume the project is on hold or you've gone another direction — totally fine, and I appreciate you having considered us. I'll stop the nudges. If anything comes up in the next few months — even just a DFM opinion on a drawing — my door is open. And if you'd like me to keep sending our monthly capacity snapshot (~1 email/month, easy unsubscribe), just reply "keep me on". Wishing you a good quarter, {Your Name}

{名字} 您好， Q26-0715-01 一直没您的回音，我理解为项目暂缓或已选他家——完全没问题，感谢您曾把我们纳入考虑。 我不再打扰。未来几个月如有任何需求——哪怕只是一张图纸想听 DFM 建议——都欢迎来找我。如果希望继续收到我方每月的产能快照（约 1 封/月，随时退订），回复 "keep me on" 即可。 祝您本季度顺利。
