[圖10(a)]和軸向前角γp[圖10(b)]，徑向前角γf主要影響切削功率；軸向前角γp則影響切屑的形成和軸向力的方向，當(dāng)γp為正值時切屑即飛離加工面。　　雙負(fù)前角　雙負(fù)前角的銑刀通常均采用方形（或長方形）無后角的刀片，刀具切削刃多（一般為8個），且強(qiáng)度高、抗沖擊性好，適用于鑄鋼、鑄鐵的粗加工。由于切屑收縮比大，需要較大的切削力，因此要求機(jī)床具有較大功率和較高剛性。由于軸向前角為負(fù)值，切屑不能自動流出，當(dāng)切削韌性材料時易出現(xiàn)積屑瘤和刀具振動。凡能采用雙負(fù)前角刀具加工時建議優(yōu)先選用雙負(fù)前角銑刀，以便充分利用和節(jié)省刀片，多功能銑刀代理商。當(dāng)采用雙正前角銑刀產(chǎn)生崩刃（即沖擊載荷大）時，多功能銑刀代理商，在機(jī)床允許的條件下亦應(yīng)優(yōu)先選用雙負(fù)前角銑刀，多功能銑刀代理商。厚度的挑選鋸片的厚度從理論上我們希望鋸片越薄越好，鋸縫實際上是一種耗費(fèi)。多功能銑刀代理商</p><div

切削平面：通過切削刃并與基面垂直的平面。③ 前刀面：切屑流出的平面。④ 后刀面：與加工表面相對的面。2、圓柱銑刀的主要幾何角度及作用。① 前角γ0：前刀面與基面之間的夾角。作用是使刀刃鋒利，切削時金屬變形減小，切屑容易排出，從而使切削省力；② 后角α0：后刀面與切削平面之間的夾角。其主要作用是減少后刀面與切削平面之間的磨擦，減小工件的表面粗糙度；③ 旋角0：螺旋齒刀刃上的切線與銑刀軸線之間的夾角。作用是使刀齒逐步地切入和切離工件，提高切削平穩(wěn)性。同時，對于圓柱銑刀，還有使切屑從端面順利流出的作用。青島T型槽銑刀當(dāng)合金銑刀振動時，應(yīng)考慮降低分切圓刀片切削速度進(jìn)給速度。</p><div style="width:100%;text-align: center;"><img

style="text-indent:25px">使用銑刀:碎片形成盡管有多種不同類型的銑刀，但是了解切屑的形成對于使用它們是至關(guān)重要的。當(dāng)銑刀旋轉(zhuǎn)時，待切割的材料被送入其中，并且切割器的每個齒切掉一小塊材料。實現(xiàn)正確的碎片尺寸至關(guān)重要。該碎片的尺寸取決于幾個變量。表面切割速度 (Vc)：這是刀具旋轉(zhuǎn)時每根牙齒穿過材料的速度。這是以公制國家/分鐘的米/秒或美國每分鐘表面英尺（SFM）來衡量的。某些鋼的切割速度的典型值為10m/min至60m/min，鋁為100m/min和600m/min。這不應(yīng)該與進(jìn)給速率混淆。該值也稱為“切向速度”。</p><p style="text-indent:25px">不同螺旋角的立銑刀：立銑刀的螺旋角越大，工件與切削刃的接觸長度就越長。這樣可以降低單位長度切削刃所承受的負(fù)載，因此可延長刀具壽命。但同時，切削阻力會變大，因此必須考慮采用夾持剛性高的刀柄。對于不銹鋼類導(dǎo)熱率較低且對刃尖受熱影響較大的難切削材料，采用大螺旋角型立銑刀進(jìn)行切削，有助于延長刀具壽命。此外，精加工面的特性因螺旋角而發(fā)生改變。例如，需進(jìn)行平滑精加工時，有時也可使用大螺旋角型立銑刀。但是，使用大螺旋角型立銑刀時，切削阻力會增大、右螺旋角刀具向外脫出的力也會變大，因此必須采取相應(yīng)措施，如使用夾持剛性高的刀柄。雖然可確保刀具的剛性，但在薄板加工等工件剛性較低的情況下，有時也會使用小螺旋角型立銑刀。合金銑刀基體的資料和制作鋸片的工藝決議了鋸片的厚度。</p><div

style="text-indent:25px">銑刀幾何角度的選擇:（1）前角的選擇。銑刀的前角應(yīng)根據(jù)刀具和工件的材料確定。銑削時常有沖擊，故應(yīng)保證切削刃有較高的強(qiáng)度。一般情況下銑刀前角小于車刀切削前角；高速鋼比硬質(zhì)合金刀具要大；另外，在銑削塑性材料時，由于切削變形較大，應(yīng)取較大的前角；銑削脆性材料時，前角應(yīng)小些；在加工強(qiáng)度大、硬度高的材料時，還可采用負(fù)前角。（2）刃傾角的選擇。立銑刀和圓柱銑刀的外圓螺旋角β就是刃傾角λ s。這使刀齒可以逐漸的切入和切出工件，提高銑削的平穩(wěn)性。增大β，可以使實際前角增大，切削刃鋒利，同時也使切屑易于排出。對于銑削寬度較窄的銑刀，增大螺旋角β的意義不大，故一般取β=0或較小的值.涂層：正確的工具涂層可以通過提高切割速度和刀具壽命以及改善表面光潔度對切割過程產(chǎn)生很大的影響。青島球頭銑刀定制</p><p style="text-indent:25px">在銑削狹窄工件或銑削型腔時要確保有足夠的刀片和工件嚙合。多功能銑刀代理商</p><p style="text-indent:25px">銑刀加工的材料及硬度。銑刀的規(guī)格，如：刃長、全長、刃徑、柄徑等。如果是數(shù)控加工中心上用的，那就應(yīng)該選用整體硬質(zhì)合金的，普通銑床上用的就可以選用白鋼的。白鋼銑刀和硬質(zhì)合金銑刀相比硬度較軟。高速鋼刀便宜，韌性好，但強(qiáng)度不高，容易讓刀，而且耐磨性，熱硬性相對來說較差，高速鋼銑刀的熱硬性600度左右，硬度65HRC左右，很明顯當(dāng)用白鋼銑較硬材料的時候，如果冷卻液不到位的話很容易燒刀這就是熱硬性不高的原因之一。硬質(zhì)合金銑刀熱硬性好，耐磨，但抗沖擊性能差，隨便摔一下刀刃就會碎，硬質(zhì)合金是用粉末冶金的方法制成的材料，硬度可達(dá)90HRA左右,熱性性可達(dá)900-1000度左右。所以，白鋼適合普通銑床用，合金銑刀時候數(shù)控加工中心用。多功能銑刀代理商</p></p><br
