style="text-indent:25px">CVD金剛石是一種高抗磨性的純金剛石材料，不含結(jié)合劑，它是在低壓（﹤0.1MPa）下制備的。CVD金剛石主要有CVD薄膜涂層（CD）和CVD厚膜（TFD）兩種形式。CD是用CVD（化學(xué)氣相沈積）工藝，在硬質(zhì)合金基體（常用K類合金）上沈積一層厚度約10~30μm，由多晶組成的膜狀金剛石而成。因基體易于制成復(fù)雜形狀，故適用于幾何形狀復(fù)雜的刀具，如絲錐、鉆頭、立銑刀和帶斷屑槽可轉(zhuǎn)位刀片等，舟山質(zhì)量好的找金剛石車刀。國(guó)際工具巿場(chǎng)上已有CD刀具的產(chǎn)品，主要用于有色金屬及非金屬材料的高速精密加工，刀具壽命比未涂層的硬質(zhì)合金刀具提高近十倍甚至數(shù)十倍。但CD刀具不適于加工金屬一類復(fù)合材料，舟山質(zhì)量好的找金剛石車刀，因?yàn)閺?fù)合材料中的硬質(zhì)顆粒在很短時(shí)間內(nèi)就會(huì)將刀具表面一層涂層磨穿，所以CD刀具的價(jià)格比同類PCD刀具要低，舟山質(zhì)量好的找金剛石車刀。PCD刀具可在極高的主軸轉(zhuǎn)速下進(jìn)行切削加工，切削速度的變化對(duì)加工質(zhì)量的影響不容忽視。舟山質(zhì)量好的找金剛石車刀</p><div

style="text-indent:25px">PCD刀具的刃磨工藝：PCD的高硬度使其材料去除率極低（甚至只有硬質(zhì)合金去除率的萬(wàn)分之一）。PCD刀具刃磨工藝主要采用陶瓷結(jié)合劑金剛石砂輪進(jìn)行磨削。由于砂輪磨料與PCD之間的磨削是兩種硬度相近的材料間的相互作用，因此其磨削規(guī)律比較復(fù)雜。對(duì)于高粒度、低轉(zhuǎn)速砂輪，采用水溶性冷卻液可提高PCD的磨削效率和磨削精度。砂輪結(jié)合劑的選擇應(yīng)視磨床類型和加工條件而定。由于電火花磨削（EDG）技術(shù)幾乎不受被磨削工件硬度的影響，因此采用EDG技術(shù)磨削PCD具有較大優(yōu)勢(shì)。某些復(fù)雜形狀PCD刀具（如木工刀具）的磨削也對(duì)這種靈活的磨削工藝具有巨大需求。隨著電火花磨削技術(shù)的不斷發(fā)展，EDG技術(shù)將成為PCD磨削的一個(gè)主要發(fā)展方向。</p><p style="text-indent:25px">復(fù)合刀片的抗彎強(qiáng)度與硬質(zhì)合金基本一致，硬度接近PCD，故可以替代PCD使用。PCD及人造聚晶金剛石復(fù)合片(PDC)刀具的刃口鋒利性和加工的工件表面質(zhì)量低于ND。同時(shí)其可加工性很差，磨削比小，難以根據(jù)刀頭的幾何形狀任意成形。利用人造聚晶金剛石復(fù)合片只能制備車刀，還不能制造帶斷屑槽的可轉(zhuǎn)位刀片和復(fù)雜三維曲面幾何形狀的銑刀。金剛石厚膜焊接刀具是把激光切割好CVD金剛石厚膜一次焊接至基體(通常為K類硬質(zhì)合金)上，形成復(fù)合片，然后拋光復(fù)合片，二次焊接至刀體上，刃磨成需要的形狀和刃口。為CVD金剛石厚膜(金剛石膜厚度達(dá)30μm)，具有硬度高、耐磨損、摩擦系數(shù)小等特點(diǎn)，是制造切削有色金屬和非金屬材料刀具的理想材料。由于金剛石焊接過(guò)程工藝復(fù)雜，CVD金剛石厚膜(TDF)焊接刀具尚未大批量應(yīng)用。開(kāi)發(fā)新型耐磨且穩(wěn)定的超硬切削刀具是許多高校和科研院所研究的課題。</p><div

style="text-indent:25px">金剛石由碳原子構(gòu)成。某些材料受熱時(shí)，會(huì)從金剛石中吸出碳原子并在工件中形成碳化物。鐵就是此類材料之一。用金剛石刀具加工鐵族材料時(shí)，摩擦產(chǎn)生的熱量會(huì)使金剛石中的碳原子擴(kuò)散到鐵中，從而造成金剛石涂層因化學(xué)磨損而提前失效。重磨和(或)重涂層的金剛石涂層刀具質(zhì)量難以保證由于刀具表面生成的涂層為純金剛石，因此用金剛石磨輪對(duì)刀具進(jìn)行重磨需要耗費(fèi)很長(zhǎng)時(shí)間。此外，為使金剛石生長(zhǎng)而采用的刀具。制備工藝會(huì)改變刀具表面的化學(xué)特性，由于涂層時(shí)要求對(duì)這種化學(xué)特性進(jìn)行非常精確的控制，因此刀具重新涂層的效果難以得到保證。舟山質(zhì)量好的找金剛石車刀</p></p><br
