精密機(jī)械零部件加工一般都是針對精密機(jī)械設(shè)備的零部件進(jìn)行加工生產(chǎn)，這就要求達(dá)到的精度非常高，因此我們除了要了解精密機(jī)械零部件加工對材料的具體要求以及精密機(jī)械零部件加工的常用技巧，還應(yīng)當(dāng)要了解精密機(jī)械零部件加工的加工過程都有哪些步驟，下面跟大家分享一下精密機(jī)械零部件加工的5個(gè)階段。1.粗加工主要考慮的是提高生產(chǎn)率。各個(gè)加工面大部分加工余量被切除，且加工出精基準(zhǔn)。2.半精加工主要是切除粗加工后可能產(chǎn)生的缺陷，同時(shí)完成次要表面的加工。須達(dá)到一定的加工精度以便為精加工階段做準(zhǔn)備，保證適當(dāng)?shù)木庸び嗔俊?.精加工在精加工階段主要采用大的切削速度、小的進(jìn)給量和切削深度切除半精加工留下的加工余量，使精密機(jī)械零部件表面滿足圖紙的技術(shù)要求。4.光整加工主要用于降低表面粗糙度或強(qiáng)化加工表面，主要用于表面粗糙度要求很高的表面加工。5.超精密加工主要是用精密切削、精鏡面磨削、精密研磨和拋光等加工方法使工件的加工精度在μm，表面粗糙度值ra≤μm。精密機(jī)械零部件加工的5個(gè)階段是由粗到細(xì)，逐步加精的過程，經(jīng)過這5個(gè)階段的加工，機(jī)械零部件的精度就能達(dá)到客戶所需的要求。專注于精密機(jī)械零部件加工與制造，可以根據(jù)客戶需求來圖來料加工。</p><p>
