style="text-indent:25px">高速鋼車刀俗稱白鋼刀，一般為整體式高速鋼結(jié)構(gòu)，也有為節(jié)約成本而采用頭部高速鋼與45#鋼刀桿通過(guò)錳鐵玻璃粉高溫焊接在一起的焊接式結(jié)構(gòu)。同樣屬于高速鋼車刀，高速鋼車刀一般經(jīng)過(guò)高溫鍛造，鹽浴爐淬火，加硬，再回火增加韌性以達(dá)到較合理性能，平磨床磨光表面，檢驗(yàn)甄選，打字，包裝等過(guò)程，這樣合格的高速鋼車刀就可正常出廠了，一般高速鋼材料按照其元素含量分為W6Mo5Cr4V2等材質(zhì)，硬度洛氏62-65度之間，另外為適應(yīng)更高硬度工件還出現(xiàn)了含鈷高速鋼產(chǎn)品，通過(guò)提高鈷的含量提高自身硬度，如M42，co3n，M2AL，M35等材質(zhì)，準(zhǔn)硬度能達(dá)到洛氏65-70度左右，近年來(lái)由我國(guó)自主研發(fā)的V3N超硬高速鋼甚至硬度達(dá)到了68-70，使國(guó)產(chǎn)高速鋼有了很強(qiáng)的國(guó)際競(jìng)爭(zhēng)力。高速鋼車刀為早年工業(yè)欠發(fā)達(dá)時(shí)期的普遍應(yīng)用產(chǎn)品，優(yōu)點(diǎn)是通過(guò)不斷使用不斷修磨，利用率較高，缺點(diǎn)是由于自身材料原因，不能突破硬度瓶頸，屬于較通用產(chǎn)品，是粗加工半精加工的得力工具。</p><p style="text-indent:25px">近年來(lái)，我國(guó)五金工具工業(yè)雖有不小發(fā)展，但遠(yuǎn)落后于機(jī)床業(yè)的發(fā)展。據(jù)數(shù)據(jù)，我國(guó)目前年刀具銷售額為145億元，其中硬質(zhì)合金刀具所占比例不足25％，不僅與國(guó)際市場(chǎng)刀具產(chǎn)品結(jié)構(gòu)相去甚遠(yuǎn)，也不能滿足國(guó)內(nèi)制造業(yè)對(duì)硬質(zhì)合金刀具日益增長(zhǎng)的需求。目前，刀具結(jié)構(gòu)失衡就是生產(chǎn)的刀具與需求不對(duì)路。例如：用戶需要的硬質(zhì)合金刀具缺口很大，但高速鋼刀具卻生產(chǎn)過(guò)剩；現(xiàn)代制造業(yè)急需的高效刀具缺口很大，但低檔標(biāo)準(zhǔn)刀具卻生產(chǎn)過(guò)剩。國(guó)際模具及五金塑膠產(chǎn)業(yè)供應(yīng)商協(xié)會(huì)秘書長(zhǎng)羅百輝認(rèn)為，從機(jī)械制造業(yè)的技術(shù)發(fā)展趨勢(shì)來(lái)看，今后我國(guó)工廠中的高效數(shù)控機(jī)床的比重將逐年增加，高效先進(jìn)刀具的需求量將隨之迅速增加，而傳統(tǒng)標(biāo)準(zhǔn)刀具的需要量將逐年減少。多個(gè)規(guī)格和類型的自動(dòng)車床車刀被普遍用于自動(dòng)車床、數(shù)控車床、普通車床、儀表車床等多種機(jī)床加工用刀具。</p><div

style="text-indent:25px">在傳統(tǒng)的技術(shù)上，由于車刀只能加工一道工序，所以一個(gè)零件的加工完成需要多道工序。一般在加工零件時(shí)需要在機(jī)床上夾裝多種車刀。當(dāng)一個(gè)車刀完成其工作時(shí)退出，另一個(gè)車刀進(jìn)入對(duì)零件進(jìn)行車削。這時(shí)，不僅需要增加夾裝設(shè)備而且還需要技術(shù)人員浪費(fèi)大量的時(shí)間去裝夾車刀。此外，一個(gè)零件的精度也因車刀二次裝夾而精度不一致。該車刀能夠車刀內(nèi)孔端面、內(nèi)孔以及斜槽，減少了車削過(guò)程中的夾裝的工序，避免了因車刀二次夾裝而引起的精度誤差以保證了零件尺寸的一致性，提高生產(chǎn)效率；在車刀端部設(shè)計(jì)的避空段可以有效地避開被加工零件，防止車刀在車削過(guò)程刮花零件，方便了車刀加工體積較小的零件；刀尖設(shè)計(jì)為圓弧過(guò)渡刃可以提高刀尖的強(qiáng)度，降低加工表面粗糙度。用于加工簡(jiǎn)單的外成形表面,如螺紋車刀等。南京端面車刀哪家好</p><p style="text-indent:25px">在滿足以上要求時(shí)，盡可能使結(jié)構(gòu)簡(jiǎn)單，制造和使用方便。南京端面車刀哪家好</p><p style="text-indent:25px">車刀種類和用途。機(jī)夾車刀。機(jī)夾車刀是采用普通刀片，用機(jī)械夾固的方法將刀片夾持在刀桿上使用的車刀。此類刀具有如下特點(diǎn)：（1）刀片不經(jīng)過(guò)高溫焊接，避免了因焊接而引起的刀片硬度下降、產(chǎn)生裂紋等缺陷，提高了刀具的耐用度。（2）由于刀具耐用度提高，使用時(shí)間較長(zhǎng)，換刀時(shí)間縮短，提高了生產(chǎn)效率。（3）刀桿可重復(fù)使用，既節(jié)省了鋼材又提高了刀片的利用率，刀片由制造廠家回收再制，提高了經(jīng)濟(jì)效益，降低了刀具成本。（4）刀片重磨后，尺寸會(huì)逐漸變小，為了恢復(fù)刀片的工作位置，往往在車刀結(jié)構(gòu)上設(shè)有刀片的調(diào)整機(jī)構(gòu)，以增加刀片的重磨次數(shù)。（5）壓緊刀片所用的壓板端部，可以起斷屑器作用。南京端面車刀哪家好</p></p><br
