style="text-indent:25px">零件變形主要有以下幾點(diǎn)：內(nèi)力作用導(dǎo)致零件加工精度改變。技術(shù)工人都知道，在加工時(shí)，零件被車床的三爪卡緊，確保零件在加工的時(shí)候，受到的力量是穩(wěn)定的，久而久之，就會(huì)造成車床卡盤松掉，使得零件受力縮小，就會(huì)出現(xiàn)變形。熱處理加工容易產(chǎn)生變形。在加工一些薄而小的零件時(shí)，一般要先對其進(jìn)行熱處理，這時(shí)如果由于技術(shù)人員的專業(yè)知識不扎實(shí)，不能很好的了解這些零件的結(jié)構(gòu)性能，很容易使得零件出現(xiàn)彎曲的現(xiàn)象。外力作用導(dǎo)致的零件加工出現(xiàn)彈性變形。在進(jìn)行零件加工時(shí)，會(huì)常常用到車床和夾具，當(dāng)兩者不平整時(shí)，會(huì)出現(xiàn)在固定零件時(shí)受力不均勻，那受力小的一方會(huì)產(chǎn)生變形。改進(jìn)措施在零件經(jīng)過熱處理并進(jìn)行自然變形后，再采用專業(yè)的切割工具進(jìn)行修整，保證零件的完美。進(jìn)行技術(shù)創(chuàng)新，增加零件剛度。技術(shù)人員需要提高技術(shù)，加大創(chuàng)新，選用合適的限熱處理方式，改變零件的剛度，這樣使得零件不易出現(xiàn)變形。非標(biāo)零部件加工的處理方式按照物件的種類性質(zhì)的不同分別會(huì)采用兩種不同的加工方式。</p><div

1微米的尺寸精度和0.5微米的不圓度。研磨利用配合件互研的原理對被加工表面上不規(guī)則的凸起部位進(jìn)行選擇加工。磨粒直徑、切削力和切削熱均可精確控制，因而是精密加工技術(shù)中獲得較高精度的加工方法。飛行器的精密伺服部件中的液壓或氣動(dòng)配合件、動(dòng)壓陀螺馬達(dá)的軸承零件都采用這種方法加工,以達(dá)到0.1甚至0.01微米的精度和0.005微米的微觀不平度。表面粗糙度是反映零件表面微觀幾何形狀誤差的一個(gè)重要技術(shù)指標(biāo)。連云港非標(biāo)零部件工廠</p><p
