style="text-indent:25px">從切削工藝上分類車削刀具有外圓車刀、端面車刀、內(nèi)孔車刀和成形車刀等。鉆削刀具有普通麻花鉆、可轉(zhuǎn)位淺鉆孔和擴(kuò)孔鉆等。鏜削刀具有單刃鏜刀、多刃鏜刀、和多刃組合鏜刀等。銑削刀具有面銑刀、立銑刀、鍵槽銑刀、模具銑刀和成形銑刀等。數(shù)控車床刀具種類從制造所采用的材料高速鋼刀具高速鋼通常是型坯材料，韌性較硬質(zhì)合金好，硬度、耐磨性和紅硬性較硬質(zhì)合金差，不適于切削硬度較高的材料，也不適于進(jìn)行高速切削。高速鋼刀具使用前需生產(chǎn)者自行刃磨，且刃磨方便，適于各種特殊需要的非標(biāo)準(zhǔn)刀具。</p><p style="text-indent:25px">立方氮化硼刀片的性能及適合加工材質(zhì)?立方氮化硼刀片的硬度比陶瓷刀片高很多，由于硬度高，與金剛石并稱為超硬材料，常用來加工硬度高于RC48的材料，它有極好的高溫硬度--高達(dá)2000℃，盡管比硬質(zhì)合金刀片脆，但與陶瓷刀片相比，沖擊強度和抗破碎性能有明顯提高。此外，一些特制的立方氮化硼刀片（華超超硬BN-S10和BN-s20牌號）能抵御大余量粗加工的切屑負(fù)荷，并能承受間斷切削加工時的沖擊以及精加工時的磨損和切削熱，這些特點可以滿足用立方氮化硼刀片粗加工淬火鋼等難加工材料。?車刀的切削部分和柄部(即裝夾部分)的結(jié)合方式主要有整體式、焊接式、機械夾固式和焊接-機械夾固式。</p><div

style="text-indent:25px">車刀種類和用途。1、車刀是應(yīng)用較廣的一種單刃刀具。也是學(xué)習(xí)、分析各類刀具的基礎(chǔ)。車刀用于各種車床上，加工外圓、內(nèi)孔、端面、螺紋、車槽等。2、車刀按結(jié)構(gòu)可分為整體車刀、焊接車刀、機夾車刀、可轉(zhuǎn)位車刀和成型車刀。其中可轉(zhuǎn)位車刀的應(yīng)用日益普遍，在車刀中所占比例逐漸增加。硬質(zhì)合金焊接車刀所謂焊接式車刀，就是在碳鋼刀桿上按刀具幾何角度的要求開出刀槽，用焊料將硬質(zhì)合金刀片焊接在刀槽內(nèi)，并按所選擇的幾何參數(shù)刃磨后使用的車刀。所謂焊接式車刀，就是在碳鋼刀桿上按刀具幾何角度的要求開出刀槽。上海金剛石車刀加工廠家</p><p style="text-indent:25px">可用在各類車床上加工內(nèi)外回轉(zhuǎn)體的成形表面。上海金剛石車刀加工廠家</p><p style="text-indent:25px">提高氧化鋁陶瓷刀片韌性的方法是在材料中加入結(jié)晶紋理或碳化硅晶須，通過這些特殊的平均起來*有1納米直徑，20微米長很結(jié)實的晶須，相當(dāng)程度地增加了陶瓷的韌性、強度和抗熱沖擊性能。單受其抗沖擊韌性限制，一直精車加工領(lǐng)域中使用。??和氧化鋁陶瓷刀片一樣，氮化硅陶瓷刀片比硬質(zhì)合金刀片有更高的熱硬性。它耐高溫與機械沖擊的性能也比較好，與氧化鋁陶瓷刀片相比它的缺點是在加工鋼時它的化學(xué)穩(wěn)定性不足?？墒?，用氮化硅陶瓷刀片可在1450英尺/分或更高的速度下加工灰鑄鐵。?????陶瓷刀片的適合加工材質(zhì)：陶瓷刀片不能用于加工鋁，而對灰鑄鐵、球墨鑄鐵、淬硬鋼和某些未淬硬鋼、耐熱合金則特別適合?？墒菍@些材料而言，陶瓷刀片應(yīng)用成功，還需要刀片刃口的外觀及微觀質(zhì)量保證，并需要可以佳的切削參數(shù)。?上海金剛石車刀加工廠家</p></p><br
