高碳鋼：高碳鋼車刀是由含碳量0.8%~1.5%之間的一種碳鋼，經(jīng)過淬火硬化後使用，因切削中的摩擦四很容易回火軟化，被高速鋼等其他刀具所取代。一般*適合於軟金屬材料之切削，常用者有SK1，SK2、、、、SK7等。2 高速鋼：高速鋼為一種鋼基合金俗名白車刀，含碳量0.7~0，南京整體車刀銷售公司.85%之碳鋼中加入W、Cr、V及Co等合金元素而成。例如18-4-4高速鋼材料中含有18%鎢、4%鉻以及4%釩的高速鋼。高速鋼車刀切削中產(chǎn)生的摩擦熱可高達(dá)至6000C，適合轉(zhuǎn)速1000rpm以下及螺紋之車削，南京整體車刀銷售公司，一般常用高速鋼車刀如SKH2、SKH4A、SKH5、SKH6，南京整體車刀銷售公司、SKH9等。車刀前面的型式主要根據(jù)工件材料和刀具材料的性質(zhì)而定。南京整體車刀銷售公司</p><div

style="text-indent:25px">車刀使用時(shí)的注意事項(xiàng)刀具各部分在設(shè)計(jì)完成后的安裝十分重要。刀具安裝時(shí)，要特別注意清潔。焊接內(nèi)孔車刀刀具無論粗加工還是精加工，在安裝和固定的各個(gè)環(huán)節(jié)，都必須注意清潔度。刀柄與機(jī)床的裝配，刀片的刃磨角度等等，都要擦拭干凈，然后再安裝或夾緊，切不可馬虎從事。1.安裝刀具時(shí)應(yīng)注意以下幾點(diǎn)：（1）刀頭不宜伸出太長，否則切削時(shí)容易產(chǎn)生振動(dòng)，影響工件加工精度和表面粗糙度。（2）刀尖應(yīng)與車床主軸中心線等高。車刀裝得高于中心，后角減小，前角增大，切削不順利，會(huì)使刀尖崩碎（3）車刀底面的墊片要平整，并盡可能用厚墊片，以減少墊片數(shù)量。調(diào)整好刀尖高低后，至少要用兩個(gè)螺釘交替將螺釘擰緊。南京數(shù)控內(nèi)孔車刀銷售公司車刀在結(jié)構(gòu)上可分為整體車刀、焊接裝配式車刀和機(jī)械夾固刀片的車刀。</p><div

style="text-indent:25px">內(nèi)孔車刀缺點(diǎn)：由于內(nèi)孔車刀是利用刀桿的夾持部分來安裝在車床刀架上的，所以刀桿部分和切削部分都是懸空的，長度有60mm左右，經(jīng)過刃磨后，刀桿直徑只有9mm，且加工的有效長度有33mm，當(dāng)精加工轉(zhuǎn)速相對(duì)較高，精加工的余量留不多情況下，會(huì)出現(xiàn)刀桿剛性差，振動(dòng)大，加工出來的內(nèi)孔表面容易產(chǎn)生波紋，影響內(nèi)孔精度。當(dāng)?shù)退倬噧?nèi)孔時(shí)，車出來的孔雖然表面粗糙度較小，但容易產(chǎn)生錐度，使內(nèi)孔的尺寸精度受到影響。要消除內(nèi)孔錐度，雖可將低速改為中速切削，但又由于切削時(shí)刀具會(huì)產(chǎn)生積屑瘤，使車出來的內(nèi)孔表面粗糙度增大。</p><p style="text-indent:25px">車刀刃磨砂輪的選擇：砂輪的特性由磨料、粒度、硬度、結(jié)合劑和組織5個(gè)因素決定。（1)磨料，常用的磨料有氧化物系、碳化物系和高硬磨料系3種。船上和工廠常用的是氧化鋁砂輪和碳化硅砂輪。氧化鋁砂輪磨粒硬度低(HV2000-HV2400)、韌性大，適用刃磨高速鋼車刀，其中白色的叫做白剛玉，灰褐色的叫做棕剛玉。碳化硅砂輪的磨粒硬度比氧化鋁砂輪的磨粒高(Hv2800以上)。性脆而鋒利，并且具有良好的導(dǎo)熱性和導(dǎo)電性，適用刃磨硬質(zhì)合金。其中常用的是黑色和綠色的碳化硅砂輪。而綠色的碳化硅砂輪更適合刃磨硬質(zhì)合金車刀。刀片轉(zhuǎn)位或更換新刀片后，刀尖位置的變化應(yīng)在工件精度允許的范圍內(nèi)。</p><div

style="text-indent:25px">車刀分為幾種類型？車刀在結(jié)構(gòu)上可分為整體車刀、焊接裝配式車刀和機(jī)械夾固刀片的車刀。機(jī)械夾固刀片的車刀又可分為機(jī)床車刀和可轉(zhuǎn)位車刀。1、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。 2、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。3、可轉(zhuǎn)位車刀：可轉(zhuǎn)位車刀是使用可轉(zhuǎn)位刀片的機(jī)夾車刀。一條切削刃用鈍后可迅速轉(zhuǎn)位換成相鄰的新切削刃，即可繼續(xù)工作，直到刀片上所有切削刃均已用鈍，刀片才報(bào)廢回收。更換新刀片后，車刀又可繼續(xù)工作。 4、成形車刀：成形車刀是加工回轉(zhuǎn)體成形表面的**刀具，其刃形是根據(jù)工件廓形設(shè)計(jì)的，可用在各類車床上加工內(nèi)外回轉(zhuǎn)體的成形表面。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(jī)械夾固式和焊接-機(jī)械夾固式。車刀廠家</p><p style="text-indent:25px">車刀的切削部分由主切削刃、副切削刃、前刀面、主后刀面和副后刀面，刀尖角組成。南京整體車刀銷售公司</p><p 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。南京整體車刀銷售公司</p></p><br
