Process pages
Guide 01
Dongguan 5-axis small batches: when you need 5-axis, and how we size the envelope
For 1-pc to small-batch buyers in Dongguan — not a CAM tutorial. Edges: which parts need 5-axis, envelope, and how to tick QA docs.
Guide 02
Aluminum 6061 / 7075: walls, anodize, 1 pc to small batch
首页只会说「铝也能做」。这页写采购真正要勾的边界：6061 和 7075 怎么选、壁厚建议、阳极会加几天、以及 1 件打样怎么上传。
Guide 03
Stainless 304 / 316: passivation, corrosion, inspection ticks
这页给要耐蚀、要钝化、要材质证明的采购。不把 316 写成植入级或未核实的体系认证。
Guide 04
How to tick QA docs: dimensional report / CoC / FAI / CMM
首页只说「质量文件可选」。这页写四项各自解决什么问题、什么时候不该勾、以及为什么页面不写 ISO 证书号。
Guide 05
How to book a Dongguan factory visit
公开地址写到中国广东省东莞市。要核对设备与质检流程，预约到场；街道门牌核实后再写细。
Guide 06
How to read lead time: production + international freight
「约 10 天」不是车间墙上的纯加工日。泽锐精工把交期写成东莞生产天数加目的国运输示意天数；加急约 6 天、标准约 10 天、经济约 17 天都是这种合计。
Guide 07
How global buyers source Dongguan CNC
现站已有同名指南。这页不重写首页，只补采购边界：时区、关税、验厂、非植入医疗、以及 AI 价不是锁价。
Guide 08
CAD formats and DFM: STEP first, units, critical tolerances, ≤80 MB
AI 分项依赖你传进来的几何。这页写格式白名单、单位、关键公差和薄壁/螺纹谁确认——不是 CAM 教程。
