style="text-indent:25px">銑刀產(chǎn)生磨損的原因：(1)機(jī)械磨損：由切屑與刀具前刀面、工件加工表面的彈性變形與刀具后刀面之間的劇烈摩擦而引起的磨損，稱(chēng)為機(jī)械磨損。在切削溫度不太高時(shí)，由這種摩擦引起的機(jī)械擦傷是刀具磨損的主要原因。(2)熱磨損：切削時(shí)，由于金屬的劇烈塑性變形和摩擦所產(chǎn)生的切削熱，使刀刃的硬度降低而失去切削性能所引起的磨損，稱(chēng)為熱磨損。除了上述兩種磨損外，還有以下幾種磨損：高溫高壓下，刀具與工件材料間會(huì)出現(xiàn)粘結(jié)現(xiàn)象，并有一部分刀具材料被切屑帶走，使刀具產(chǎn)生粘結(jié)磨損。在更高的溫度下，廣州醫(yī)用銑刀廠(chǎng)家，刀具材料中的某些元素(如鎢，廣州醫(yī)用銑刀廠(chǎng)家、鈷、鈦等)將向工件材料內(nèi)擴(kuò)散，廣州醫(yī)用銑刀廠(chǎng)家，從而使刀具切削部分表層的化學(xué)成分改變，也降低了刀具強(qiáng)度和耐磨性，使刀具產(chǎn)生擴(kuò)散磨損。由于硬質(zhì)合金本身比高速鋼韌性差，所以當(dāng)切削工藝選擇不當(dāng)，或機(jī)床精度較差時(shí)容易崩刃。廣州醫(yī)用銑刀廠(chǎng)家</p><div

style="text-indent:25px">銑刀的角度及選擇原則技巧：雙正前角　雙正前角銑刀采用帶有后角的刀片，這種銑刀楔角小，具有鋒利的切削刃。由于切屑收縮比小，所耗切削功率較小，切屑成螺旋狀排出，不易形成積屑瘤。這種銑刀較宜用于軟材料和不銹鋼、耐熱鋼等材料的切削加工。對(duì)于剛性差（如主軸懸伸較長(zhǎng)的鏜銑床）、功率小的機(jī)床和加工焊接結(jié)構(gòu)件時(shí)，也應(yīng)優(yōu)先選用雙正前角銑刀。正負(fù)前角（軸向正前角、徑向負(fù)前角）這種銑刀綜合了雙正前角和雙負(fù)前角銑刀的優(yōu)點(diǎn)，軸向正前角有利于切屑的形成和排出；徑向負(fù)前角可提高刀刃強(qiáng)度，改善抗沖擊性能。此種銑刀切削平穩(wěn)，排屑順利，金屬切除率高，適用于大余量銑削加工。合金銑刀適用于數(shù)控中心**刀具的安全存儲(chǔ)和運(yùn)輸，前、后、頂三面都可放置各種刀具座。</p><div

銑削寬度、深度選擇，一般銑前深度、寬度越大，銑刀直徑也應(yīng)越大。粗銑時(shí)，銑床銑刀直徑要小些;精銑時(shí)，銑刀直徑要大些，盡量包容工件整個(gè)加工寬度，減小相鄰兩次進(jìn)給之間的接刀痕跡。在對(duì)大型零件進(jìn)行面銑加工時(shí)，都是使用直徑較小的銑刀，這就為提高生產(chǎn)率留下了很大余地。在理想情況下，銑刀應(yīng)有70％的切削刃參與切削。用銑刀銑孔時(shí)，刀具尺寸變得尤為重要。相對(duì)于孔徑而言，銑刀的直徑太小，則加工時(shí)可能會(huì)在孔的中心形成一個(gè)料芯。當(dāng)料芯落下時(shí)，可能會(huì)損壞工件或刀具。銑刀直徑過(guò)大，則會(huì)損壞刀具本身和工件，因?yàn)殂姷恫辉谥行那邢鳎赡軙?huì)在刀具底部發(fā)生碰撞。大量的槽紋幾乎沒(méi)有有效的切屑去除的余地，因此它們不太適合去除大量的材料。廣州醫(yī)用銑刀廠(chǎng)家</p><p
