特別是外觀處理上使用很多的方式，或者根據(jù)環(huán)境的使用要求，對(duì)零件不進(jìn)行單獨(dú)的處理，而是在使用過程中利用封油或防銹液進(jìn)行保護(hù)，這也是在機(jī)械加工工裝中用得比較多的方式，無論是什么方式我們都得選擇一樣。當(dāng)然如果上述方式都不太適合，那我們就必須跟換材質(zhì)，例如我們可以選擇不銹鋼，這樣就可以基本上杜絕防銹處理這個(gè)尷尬了，但是很多所謂的不銹鋼其實(shí)并不是完全不生銹的，只是相對(duì)難生銹一些而已，所以在使用過程中，我們還是要充分的考慮零件或產(chǎn)品的防銹問題。03材料穩(wěn)定性如何在產(chǎn)品設(shè)計(jì)的過程中，我們選擇一個(gè)零件的材料，同時(shí)還要考慮該材料的穩(wěn)定性，例如我們前面舉例說明的HT300灰口鑄鐵，為什么機(jī)床的大件都是采用這種材料，就是因?yàn)檫@種材料在產(chǎn)品的使用過程中，有著非常好的材料穩(wěn)定性，無論是熱穩(wěn)定性還是它的材料組織穩(wěn)定性等都非常好，而對(duì)于高精度機(jī)床這種特性的產(chǎn)品，這樣的材料就是非常好的選擇，如果你選擇用鋼來做這樣的基體，那可能你加工的零件時(shí)合格，但是裝配后就會(huì)發(fā)生各種幾何變形，發(fā)到客戶手上有又會(huì)再次變形，總之就是在不斷的變形中，它們可以隨之溫度，濕度和振動(dòng)等環(huán)境的變化而隨時(shí)變化，這對(duì)于一個(gè)高精度要求的產(chǎn)品而言。零件結(jié)構(gòu)工藝性概述是什么？楊浦區(qū)國標(biāo)零部件</p><p
