| 材料 / 牌號 | 常見交貨狀態 | 切削性 | 適用情境 |
|---|---|---|---|
| 鋁合金 6061 | T6（固溶處理及時效） | 容易：切削性佳，切屑控制良好 | 支架、機殼、治具，從試作品到進入量產 |
| 鋁合金 7075 | T6 / T651 | 較難：刀具磨耗較大，需要剛性設定 | 高強度、重量敏感零件；不適合焊接 |
| 不鏽鋼 304 / 304L | 退火 | 加工硬化：轉速較低、正前角進給 | 一般耐腐蝕，食品與製程設備 |

| 粉體塗裝 | 厚實、耐用、裝飾性塗層 | 外觀即為要求時 |
| 鈍化處理 | 移除游離鐵並重建氧化膜 | 加工後的不鏽鋼零件 |
| 應力消除退火 / 熱處理 | 在切削前後釋放殘留應力 | 必須撐過加工的薄壁與緊公差零件 |
公差
ISO 2768-m 標準；專案特定公差逐案審核。
| 圖面標註 | 需要什麼 | 對成本與交期的影響 |
|---|---|---|
| 一般：±0.25 mm / ±0.010 in | 標準刀具、尺寸抽檢 | 基準：不加價 |
| 標準：±0.13 mm / ±0.005 in | 機台狀況良好、首件檢查 | 小幅加價；最常見的報價預設值 |
| 緊：±0.025 mm / ±0.001 in | 研磨或鑽石刀具、溫控、三次元測量儀（CMM） | 階躍變化：切削更慢加上全數檢驗 |
| 精密：±0.013 mm / ±0.0005 in | 精修程序、量規、受控環境 | 加工主宰價格；常成為獨立工序 |
| 位置度 / 傾斜度（GD&T） | 基準控制，相關特徵一次設定完成 | 取決於基準跨多少次設定 |
| 表面粗糙度 Ra 0.8 µm 或更細 | 更細的步進、拋光或精修走刀 | 增加一個製程步驟，不只是加工時間 |

Ordering, Lead Times & MOQ
Custom CNC parts carry no forced MOQ; ordering from a single prototype piece is standard industry practice.
Instant-quote platforms publicly advertise prototype lead times of 1-3 business days.
Online RFQ is the industry-standard flow: upload a 3D model (STEP/STP/DWG/DXF), receive an instant quote or engineer review, then production, inspection, and delivery.
常見問題
在中國生產，你們如何控制品質？
每批在出廠前都對照圖面檢驗，出貨時您會收到尺寸報告。關鍵特徵都經過量測與記錄，而非假設。
我的圖面的智慧財產如何保護？
圖面僅用於報價與生產您的訂單。我們可依需求簽署保密協議（NDA），且絕不轉售客戶零件。
可以以 DDP 條件出貨到我的國家嗎？
可以。我們以快遞、空運與海運出貨至全球；DDP 條件依目的地報價。
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.
