# 机械图纸中这两句是什么意思？

## 问题

 我刚入行机械，客户图纸上标着All sharp edges to be deburred和Surface finish: Ra 1.6，这两句具体指什么？会不会影响报关、运费和跟客户谈价格？ 

## 回答
                            
### 回答 1 — 最佳答案

您提到的这两句标注，第一句要求所有锐边去毛刺，第二句是表面粗糙度Ra 1。6微米。从合规角度，这属于精密加工件，HS编码归类时要注意是否涉及“高精度”或“特种工艺”监管条件。报关时必须随附技术规格说明，海关查验概率较高，特别是出口欧盟可能涉及CE认证或反倾销调查。建议您提前准备材料成分证明、加工工艺说明，并在报关单备注栏注明“精密加工件”，避免被误判为普通零件导致退单。

这两句对物流包装要求很高。去毛刺处理不到位，锐边会刺破防锈袋，海运途中容易生锈；Ra 1。6的表面精度，普通纸箱+泡沫的防护等级不够。建议采用真空防锈袋+定制EVA内衬+双层瓦楞纸箱，空运的话要加贴“易碎品”和“防潮”标识。走海运拼箱时，务必在提单上注明“KEEP DRY”，并选择信誉好的货代，避免目的港野蛮装卸。如果货值高，直接走整柜更保险，虽然运费贵但货损风险低。

遇到这种技术标注，商务沟通要化被动为主动。回复客户时别只说“明白了”，而是写：“关于去毛刺要求，我们会增加全检工序；Ra 1。6的精度，我们采用CNC精加工确保达标”，让客户感觉您很懂行。报价策略上，把精密加工费单独列项，既显得透明，又为后续议价留空间。付款方式坚持30%定金+70%发货前付清，因为这种定制件一旦出问题客户容易扯皮。合同里必须加一条“技术图纸经双方签字确认后作为验收标准”，防止客户事后挑毛病。
