[討論] 是我不懂加工精度嗎?
日前有個導光條的設計,長條型、一些均光的結構
長寬厚約 280x10x2.5mm,材質是壓克力
因為量的問題,最後決議不開模具,直接用cnc加工
想說cnc加工、所以280這個尺寸公差就訂正負10條
有次交貨被QC驗出尺寸大於上限20~30條
允收、sorting 的過程就不談了
廠商為了後續的交貨跟我談修改公差的事
說因為壓克力比較硬、刀子用久了會受損(說會變小)
說做久了之後,做出來的尺寸會偏大、加工會變熱影響 ← 我是聽他們在放屁啦...
大家知道廠商要我放多大嗎? 60條啊~~~
怎麼會有廠商cnc敢說出60條的公差,我直接回他們,你們敢做我不敢收勒....
大家評評理啊~~~
