圖4孔徑氣動(dòng)測(cè)頭噴嘴數(shù)量與布置（2）孔徑氣動(dòng)測(cè)頭噴嘴數(shù)量布置實(shí)踐。MA變速箱離合器殼體差速器安裝孔如圖5a所示，用氣動(dòng)測(cè)頭檢測(cè)圖中φ63+，在殼體L1線，配置的是三向噴嘴的氣動(dòng)測(cè)頭，如圖5b所示；在殼體L3線，配置的是雙向噴嘴的氣動(dòng)測(cè)頭，如圖5c所示。隨機(jī)抽查L(zhǎng)1線生產(chǎn)的2個(gè)零件，分別用兩個(gè)氣動(dòng)測(cè)頭測(cè)量φ63+，測(cè)量結(jié)果如表2所示。圖5離合器殼體差速器安裝孔氣動(dòng)測(cè)頭噴嘴數(shù)量布置表2L1線生產(chǎn)的2個(gè)零件分別在兩個(gè)氣動(dòng)塞規(guī)上的檢測(cè)結(jié)果統(tǒng)計(jì)（單位：mm）從表2數(shù)據(jù)可以看出，這兩個(gè)零件用三向噴嘴的氣動(dòng)測(cè)頭測(cè)量的直徑是合格的，重復(fù)性較好，但用雙向噴嘴的氣動(dòng)測(cè)頭測(cè)量的直徑是超差的。將差速器軸承外環(huán)裝入到這2個(gè)變速箱離合器殼體上時(shí)有卡滯現(xiàn)象，用手不能轉(zhuǎn)動(dòng)（產(chǎn)品定義該軸承與孔為小間隙配合，故工藝要求軸承外環(huán)裝入后能夠用手轉(zhuǎn)動(dòng)），因此，這兩個(gè)零件是不合格的。從這個(gè)實(shí)例可以看出：雙向噴嘴的氣動(dòng)測(cè)頭測(cè)量孔徑的準(zhǔn)確度明顯高于三向噴嘴的測(cè)量結(jié)果，對(duì)零件符合性的判定準(zhǔn)確。更換殼體L1線加工中心的刀軸軸承，將該孔直徑的加工參數(shù)調(diào)整到直徑公差的中間值，加工出的零件合格，沒(méi)有出現(xiàn)軸承外環(huán)卡滯的現(xiàn)象。</p><p style="text-indent:25px">精密機(jī)械加工，并不是什么材料都可以進(jìn)行精密加工的，有些材料硬度太大，超過(guò)了加工機(jī)件的硬度，就可能把機(jī)件崩壞，所以這些材料是不適宜精密機(jī)械加工的，除非是特殊材料制成的機(jī)件，或激光切割。對(duì)于精密機(jī)械加工的材料分為兩大類(lèi)，金屬材料和非金屬材料。對(duì)于金屬材料來(lái)說(shuō)，硬度為不銹鋼比較大，其次是鑄鐵，其次是銅，***是鋁，而陶瓷，塑料等的加工是屬于非金屬材料的加工。 1、首先是對(duì)材料硬度的要求，對(duì)有些場(chǎng)合來(lái)說(shuō)，材料是硬度越高越好，只是限于加工機(jī)件的硬度要求，加工的材料不能太硬，如果比機(jī)件還硬是無(wú)法加工的。 2、其次，材質(zhì)軟硬適中，至少要比機(jī)件硬度低一個(gè)檔次，同時(shí)還要看加工的器件的作用是做什么用，對(duì)機(jī)件合理選材。總之，精密零件加工對(duì)材質(zhì)的要求還是有一些的，并不是什么材質(zhì)都適合加工的，比如太軟或太硬的材料，前者是沒(méi)有加工的必要，而后者是無(wú)法加工。所以，**基本的一條就是，在加工前一定要注意材質(zhì)的密度，如果密度太大，相當(dāng)于硬度也很大，而硬度要是超過(guò)機(jī)件（車(chē)床車(chē)刀）的硬度，就是無(wú)法加工的，不**會(huì)損壞零件，還會(huì)造成危險(xiǎn)，比如車(chē)刀飛崩出去傷人等。所以，一般來(lái)說(shuō)，對(duì)于機(jī)械類(lèi)加工來(lái)說(shuō)，材料材質(zhì)要低于機(jī)刀的硬度，這樣才能被加熱管理系統(tǒng) 熱管理系統(tǒng)主要有4類(lèi)：風(fēng)冷、水冷、液冷、相變材料。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="吉林CNC總成加工中心,總成"

style="text-indent:25px">立方氮化硼的主要性能、特點(diǎn)：立方氮化硼的硬度雖略次于金剛石，但卻遠(yuǎn)遠(yuǎn)高于其他高硬度材料。CBN的突出優(yōu)點(diǎn)是熱穩(wěn)定性比金剛石高得多，可達(dá)1200℃以上(金剛石為700——800℃)，另一個(gè)突出優(yōu)點(diǎn)是化學(xué)惰性大，與鐵元素在1200——1300℃下也不起化學(xué)反應(yīng)。立方氮化硼的主要性能特點(diǎn)如下： ①高的硬度和耐磨性：CBN晶體結(jié)構(gòu)與金剛石相似，具有與金剛石相近的硬度和強(qiáng)度。PCBN特別適合于加工從前只能磨削的高硬度材料，能獲得較好的工件表面質(zhì)量。 ②具有很高的熱穩(wěn)定性：CBN的耐熱性可達(dá)1400——1500℃，比金剛石的耐熱性(700——800℃)幾乎高l倍。PCBN刀具可用比硬質(zhì)合金刀具高3——5倍的速度高速切削高溫合金和淬硬鋼。 ③優(yōu)良的化學(xué)穩(wěn)定性：與鐵系材料到1200—1300℃時(shí)也不起化學(xué)作用，不會(huì)像金剛石那樣急劇磨損，這時(shí)它仍能保持硬質(zhì)合金的硬度；PCBN刀具適合于切削淬火鋼零件和冷硬鑄鐵，可廣泛應(yīng)用于鑄鐵的高速切削。 ④具有較好的熱導(dǎo)性：CBN的熱導(dǎo)性雖然趕不上金剛石，但是在各類(lèi)刀具材料中PCBN的熱導(dǎo)性*次于金剛石，**高于高速鋼和硬質(zhì)合金 ⑤ 具有較低的摩擦系數(shù)：低的摩擦系數(shù)可導(dǎo)致切削時(shí)切削力減小，切削溫度降低，加工表面質(zhì)量提高。吉林CNC總成加工中心</p><p
