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，吉林鎢鋼刀輪****。 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，但是在各類刀具材料中PCBN的熱導(dǎo)性僅次于金剛石，吉林鎢鋼刀輪****，吉林鎢鋼刀輪****，**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。刀輪主要結(jié)構(gòu)為具有沿其外周的切割邊緣的盤狀件。吉林鎢鋼刀輪****</p><div style="width:100%;text-align: center;"><img style="max-width: 640px;

style="text-indent:25px">超精密加工技術(shù)，是現(xiàn)代機(jī)械制造業(yè)**主要的發(fā)展方向之一。在提高機(jī)電產(chǎn)品的性能、質(zhì)量和發(fā)展高新技術(shù)中起著至關(guān)重要的作用，并且已成為在國際競(jìng)爭(zhēng)中取得成功的關(guān)鍵技術(shù)。超精密加工是指亞微米級(jí)(尺寸誤差為0.3～0.03?m，表面粗糙度為Ra0.03～0.005?m)和納米級(jí)(精度誤差為0.03?m，表面粗糙度小于 Ra0.005?m)精度的加工。實(shí)現(xiàn)這些加工所采取的工藝方法和技術(shù)措施，則稱為超精加工技術(shù)。加之測(cè)量技術(shù)、環(huán)境保障和材料等問題，人們把這種技術(shù)總稱為超精工程。超精密加工主要包括三個(gè)領(lǐng)域：超精密切削加工如金剛石刀具的超精密切削，可加工各種鏡面。它已成功地解決了用于激光核聚變系統(tǒng)和天體望遠(yuǎn)鏡的大型拋物面鏡的加工。超精密磨削和研磨加工如高密度硬磁盤的涂層表面加工和大規(guī)模集成電路基片的加工。超精密特種加工如大規(guī)模集成電路芯片上的圖形是用電子束、離子束刻蝕的方法加工，線寬可達(dá)0.1?m。如用掃描隧道電子顯微鏡(STM)加工，線寬可達(dá)2～5nm。吉林鎢鋼刀輪成品加工凸臺(tái)、凹槽時(shí)，選高速鋼立銑刀；加工毛坯表面或粗加工孔時(shí)，可選取鑲硬質(zhì)合金刀片的玉米銑刀；</p><div

style="text-indent:25px">20世紀(jì)80年代，加工尺寸精度可達(dá)10納米(110-8米)外表粗糙度達(dá)1納米。金屬精密零件加工對(duì)工件材質(zhì)、加工設(shè)備、工具、丈量和環(huán)境等條件都有特殊的要求，需要綜合應(yīng)用精密機(jī)械、精密丈量、精密伺服系統(tǒng)、計(jì)算機(jī)控制以及其他先進(jìn)技術(shù)。金屬精密加工的有機(jī)械化學(xué)拋光、離子濺射和離子注入、電子束曝射、激光束加工、金屬蒸鍍和分子束外延等。這些方法的特點(diǎn)是對(duì)外表層物質(zhì)去除或添加的量可以作極細(xì)微的控制。但是要獲得精密的加工精度。仍有賴于精密的加工設(shè)備和精確的控制系統(tǒng)，并采用超精密掩膜作中介物。例如超大規(guī)模集成電路的制版就是采用電子束對(duì)掩膜上的光致抗蝕劑(見光刻)進(jìn)行曝**密機(jī)械制造使光致抗蝕劑的原子在電子撞擊下直接聚合(或分解)再用顯影劑把聚合過的或未聚合過的局部溶解掉，制成掩膜。電子束曝射制版需要采用工作臺(tái)定位精度高達(dá)±0.01微米的超精密加工設(shè)備。</p><p style="text-indent:25px">對(duì)精密和超精密加工所用的加工設(shè)備有下列要求： (1)高精度。包括高的靜精度和動(dòng)精度，主要的性能指標(biāo)有幾何精度、定位精度和重復(fù)定位精度、分辨率等，如主軸回轉(zhuǎn)精度、導(dǎo)軌運(yùn)動(dòng)精度、分度精度等； (2)高剛度。包括高的靜剛度和動(dòng)剛度，除本身剛度外，還應(yīng)注意接觸剛度，以及由工件、機(jī)床、刀具、夾具所組成的工藝系統(tǒng)剛度。 (3)高穩(wěn)定性。設(shè)備在經(jīng)運(yùn)輸、存儲(chǔ)以后，在規(guī)定的工作環(huán)境下使用，應(yīng)能長時(shí)間保持精度、抗干擾、穩(wěn)定工作。設(shè)備應(yīng)有良好的耐磨性、抗振性等。 (4)高自動(dòng)化。為了保證加工質(zhì)量，減少人為因素影響，加工設(shè)備多采用數(shù)控系統(tǒng)實(shí)現(xiàn)自動(dòng)化。 加工設(shè)備的質(zhì)量與基礎(chǔ)元部件，如主軸系統(tǒng)、導(dǎo)軌、直線運(yùn)動(dòng)單元和分度轉(zhuǎn)臺(tái)等密切相關(guān)，應(yīng)注意這些元部件質(zhì)量。此外，夾具、輔具等也要求有相應(yīng)的高精度、高剛度和高穩(wěn)定性。用力比一般玻璃大些，速度也要快些，這樣才不會(huì)出現(xiàn)彎曲不直。</p><div

style="text-indent:25px">在精密機(jī)械零部件加工和普通機(jī)械零件加工兩件中，越來越多人會(huì)傾向于選擇前者。同樣作為機(jī)械中的一個(gè)組成部分，精密零件為什么會(huì)更受歡迎呢？<br/> 很多零部件自身存在著一定的不足，比如說，有的外觀上達(dá)不到要求，有的適用范圍存在一定的限制。選擇精密機(jī)械零部件加工，不僅能有效改善材料品質(zhì)、零件精度，發(fā)揮其機(jī)能，還能使零件的耐用程度**提高，促使整個(gè)機(jī)械的品質(zhì)得到改善，不僅能有效改善材料品質(zhì)、零件精度，發(fā)揮其機(jī)能，還能使零件的耐用程度**提高，促使整個(gè)機(jī)械的品質(zhì)得到改善。但是，它也是有不好的，比如會(huì)造成工作變形，那么是什么因素導(dǎo)致了工作變形呢？想知道的話，跟小智一起去了解一下吧。<br/> 在零件的設(shè)計(jì)結(jié)構(gòu)上更用心：<br/> 變形量的形狀與大小復(fù)雜程度、壁厚大小比和寬長成正比，與材質(zhì)穩(wěn)定性和剛性成正比。所以在設(shè)計(jì)零件時(shí)盡可能的減小這些因素對(duì)工件變形的影響。尤其在大型零件的結(jié)構(gòu)上更應(yīng)該做到結(jié)構(gòu)合理。在加工前也要對(duì)毛坯硬度、疏松等缺點(diǎn)進(jìn)行嚴(yán)格控制，保證毛坯質(zhì)量，減少其帶來的工件變形。<br/> 鉆石刀輪具有較好的耐磨性和刃口鋒利度，通過精細(xì)研磨能夠?qū)崿F(xiàn)比較好的形位精度。吉林鎢鋼刀輪****</p><p style="text-indent:25px">同時(shí)可以切割建筑用以及汽車用玻璃，是普通玻璃刀和硬質(zhì)合金玻璃刀輪的理想替代品。吉林鎢鋼刀輪****</p><p> 切削技術(shù)落后是金屬加工行業(yè)效率低下的主要原因之一，好馬配好鞍，效率的數(shù)控設(shè)備使用低性能的切削刀架，不能充分發(fā)揮設(shè)備優(yōu)勢(shì)反而造成更大的資源浪費(fèi)。以前，我們一提到數(shù)控刀架，首先想到的就是價(jià)格昂貴的國外品牌，一些產(chǎn)品附加值較低的企業(yè)難以接受。受此影響，數(shù)控刀架主要應(yīng)用于數(shù)控機(jī)床的精加工階段，大多數(shù)普通機(jī)床仍然使用廉價(jià)的焊接刀架，正常磨損后，進(jìn)行多次重磨。磨刀難，磨好刀更難，操作者除了熟練掌握磨刀方法與操作要領(lǐng)，還要有很高的悟性才能領(lǐng)略其中的奧妙。十年苦功更是跟不上企業(yè)發(fā)展的步伐。適當(dāng)加大刀架投入，將生產(chǎn)工人從繁瑣的磨刀勞動(dòng)中解放出來，集中精力、專心致志地操作機(jī)床是提高生產(chǎn)效率的關(guān)鍵一步。電動(dòng)刀架作為數(shù)控車床的重要配置,在機(jī)床運(yùn)行中起著至關(guān)重要的作用,一旦出現(xiàn)故障很可能造成工件報(bào)廢,甚至造成卡盤與刀架碰撞的事件。在數(shù)控機(jī)床的故障維修中,電氣控制部分線路復(fù)雜,故障現(xiàn)象多變,有些故障現(xiàn)象不太明顯,查找難度比較大,而機(jī)械部分與普通機(jī)床比較類似,故障相對(duì)容易排除。電動(dòng)刀架一般有四工位或六工位,由電動(dòng)機(jī)、機(jī)械換刀機(jī)構(gòu)、發(fā)信盤等組成,當(dāng)系統(tǒng)發(fā)出換刀信號(hào),刀架電機(jī)正轉(zhuǎn),通過減速機(jī)構(gòu)和升降機(jī)構(gòu)將上刀體上升至一定位置。吉林鎢鋼刀輪****</p><p
