style="text-indent:25px">PCD刀具的特點：PCD是通過金屬結(jié)合劑（如Co、Ni等）將金剛石微粉聚合而成的多晶材料。PCD的硬度低于單晶金剛石，北京品牌金剛石刀具片，但PCD屬各向同性材料；PCD具有導電性，便于切割成型，成本遠低于天然金剛石。PCD原料來源豐富，價格只有天然金剛石的十幾分之一，北京品牌金剛石刀具片，PCD應用遠比天然金剛石刀具普遍。大多數(shù)PCD刀片都是與硬質(zhì)合金基體燒結(jié)而成的復合片，即在硬質(zhì)合金的基體上燒結(jié)一層約0.5mm厚的PCD，這種刀片的強度和硬質(zhì)合金基體一致，硬度接近整體PCD，北京品牌金剛石刀具片，可焊性好，重磨容易，成本低。在金剛石刀具中單晶金剛石用作切削刀具必須是大顆粒的。北京品牌金剛石刀具片</p><div

style="text-indent:25px">PCD刀具的主要應用領域:1航空航天領域,復合材料相比于其它材料具有質(zhì)量輕、強度高、耐高溫、耐腐蝕等特性，成為航空航天領域的理想材料。隨著航空航天復合材料的普遍應用，如何正確選擇、合理使用刀具進行高效高質(zhì)量切削加工是一個非常重要的問題。航空航天制造業(yè)普遍應用的刀具材料主要有硬質(zhì)合金和PCD刀具材料，其中，PCD刀具材料所占比重越來越大，在當今的航空制造中兩者成為航空航天業(yè)刀具發(fā)展中的主導刀具，應用范圍相當普遍。2汽車行業(yè)領域,PCD刀具于1973年在美國開始應用。北京品牌金剛石刀具片PCBN是在高溫、高壓下，將許多CBN單晶粉聚晶成的多晶體材料，是CBN單晶粉的燒結(jié)體。</p><div

style="text-indent:25px">在金剛石刀具中直線刃刀頭：安裝很難，需要有高超的安裝技術，有10°角度誤差就會影響精加工表面質(zhì)量，但是這種刀頭的加工表面精度較好。圓弧刃刀頭：安裝容易，但加工表面精度稍差一點，因此較好采用能微調(diào)安裝角度的直線刃刀頭。但是加工曲率半徑小的聚光反射鏡等則必須采用四圓弧刃刀頭。粗研一顆單晶金剛石毛坯，要做成精密刀具，先要晶體定向，確定前后刀面位置，確定需磨出的部分仔細檢查內(nèi)部有無缺陷。精研是制造金剛石刀具的關鍵工序，主要考慮提高研磨質(zhì)量，使切削刃更鋒利。研磨盤小圓周處加細微粉用于精研，采取逆磨，即沿刃口指向刀體內(nèi)的方向研磨，切削刃承受壓應力，得到鋒利完好的刃口。</p><p style="text-indent:25px">金剛石刀具的結(jié)晶各向異性，刀具價格昂貴。PCD的性能取決于金剛石晶粒及鈷的含量，刀具壽命為硬質(zhì)合金(WC基體)刀具的10～500倍。主要用于車削加工各種有色金屬如鋁、銅、鎂及其合金、硬質(zhì)合金和耐磨性極強的纖維增塑材料、金屬基復合材料、木材等非金屬材料。切削加工時切削速度、進給速度和切削深度加工條件取決于工件材料以及硬度。人造聚晶金剛石復合片(PDC)性能和應用接近PCD刀具，主要用在有色金屬、硬質(zhì)合金、陶瓷、非金屬材料(塑料、硬質(zhì)橡膠、碳棒、木材、水泥制品等)、復合材料等切削加工，逐漸替代硬質(zhì)合金刀具。由于金剛石顆粒間有部分殘余粘結(jié)金屬和石墨，其中粘結(jié)金屬以聚結(jié)態(tài)或呈葉脈狀分布會減低刀具耐磨性和壽命。PCD刀具的正確應用是獲得滿意加工效果的前提。</p><div

style="text-indent:25px">金剛石刀具的材料分為三種：天然單晶金剛石刀具、人造聚晶金剛石刀具及金剛石燒結(jié)體。天然單晶金剛石主要用于非鐵材料及非金屬的精密加工。單晶金剛石結(jié)晶界面有一定的方向，不同的晶面上硬度和耐磨性有較大差異，刃磨時需選定某一平面，否則影響刃磨與使用質(zhì)量。人造金剛石是通過合金催化劑的作用，在高溫高壓下由石墨轉(zhuǎn)化而成。我國20世紀60年代就成功制得第1顆人造金剛石。人造聚晶金剛石是將金剛石微晶在高溫高壓下再燒結(jié)而成，可制成所需形狀尺寸，鑲嵌在刀桿上使用。由于抗沖擊強度提高，可選用較大切削用量。金剛石燒結(jié)體是在硬質(zhì)合金基體上燒結(jié)一層約0.5mm厚的聚晶金剛石。金剛石燒結(jié)體強度較好，允許切削斷面較大，也能間斷切削，可多次重磨使用。PCD刀具的性能取決于金剛石晶粒及鈷的含量。廣州金剛石切割刀片哪里有賣的</p><p

style="text-indent:25px">金剛石涂層刀具是用CVD法直接在硬質(zhì)合金(K類硬質(zhì)合金)或陶瓷等基體上沉積一層1～25μm金剛石薄膜，無解理面各向同性。薄膜涂層刀具硬度達9800～10000HV。熱導率高，室溫下導熱系數(shù)高達2000W·m-1·K-1，而硬質(zhì)合金刀具導熱系數(shù)*為80～100m-1·K-1。CVD方法金剛石可以涂層到任何復雜形狀的刀具上，這是聚晶金剛石無法擁有的較明顯的優(yōu)勢。立方氮化硼(PCBN)是繼人工合成金剛石之后出現(xiàn)的第二種無機超硬材料,其硬度略次于金剛石,熱穩(wěn)定性好,耐熱性可達到1400~1500度,比金剛石的耐熱性(700~800度)幾乎高一倍。北京品牌金剛石刀具片</p></p><br
