style="text-indent:25px">非標(biāo)刀具要注意的點(diǎn)：1.刀具的幾何形狀較為復(fù)雜，在熱處理時(shí)，刀具容易發(fā)生彎曲、變形，或者是局部的應(yīng)力集中，這就應(yīng)該在設(shè)計(jì)時(shí)就注意避免容易發(fā)生應(yīng)力集中的部位，對(duì)直徑變化較大的部位，加上斜角過(guò)渡或臺(tái)階設(shè)計(jì)等。2.如果是表面粗糙度問(wèn)題，可以通過(guò)對(duì)刃部的幾何角度的改變來(lái)實(shí)現(xiàn)，如加大前、后角的度數(shù)會(huì)明顯改善工件表面粗糙度。但如果使用方的機(jī)床剛性不夠的話，可能刃口倒鈍反而能提高表面粗糙度，這方面的東西非常復(fù)雜，需對(duì)加工現(xiàn)場(chǎng)分析后才能得出結(jié)論。非標(biāo)刀具尺寸相差不能太大，一般不要超過(guò)2mm，四川數(shù)控機(jī)床刀具，四川數(shù)控機(jī)床刀具，因?yàn)槌叽缦嗖钐蟮脑?，?huì)引起刀具的槽形發(fā)生變化，四川數(shù)控機(jī)床刀具，直接影響容屑空間和幾何角度。非標(biāo)刀具的使用在不規(guī)則零件的生產(chǎn)中能夠?yàn)楦咝У纳a(chǎn)帶去不一樣的效果。四川數(shù)控機(jī)床刀具</p><div

style="text-indent:25px">切削刀具材料與加工對(duì)象的物理性能匹配：具有不同物理性能的刀具，如，高導(dǎo)熱和低熔點(diǎn)的高速鋼刀具、高熔點(diǎn)和低熱脹的陶瓷刀具、高導(dǎo)熱和低熱脹的金剛石刀具等，所適合加工的工件材料有所不同。加工導(dǎo)熱性差的工件時(shí)，應(yīng)采用導(dǎo)熱較好的刀具材料，以使切削熱得以迅速傳出而降低切削溫度。金剛石由于導(dǎo)熱系數(shù)及熱擴(kuò)散率高，切削熱容易散出，不會(huì)產(chǎn)生很大的熱變形，這對(duì)尺寸精度要求很高的精密加工刀具來(lái)說(shuō)尤為重要。數(shù)控刀具材料的合理選擇：一般而言，PCBN、陶瓷刀具、涂層硬質(zhì)合金及TiCN基硬質(zhì)合金刀具適合于鋼鐵等黑色金屬的數(shù)控加工；而PCD刀具適合于對(duì)Al、Mg、Cu等有色金屬材料及其合金和非金屬材料的加工。四川數(shù)控機(jī)床刀具非標(biāo)刀具的加工是比較困難的。</p><div

style="text-indent:25px">圓弧形車(chē)刀是較為特殊的數(shù)控加工用車(chē)刀。其特征是，構(gòu)成主切削刃的刀刃形狀為一圓度誤差或線輪廓度誤差很小的圓弧；該圓弧刃每一點(diǎn)都是圓弧形車(chē)刀的刀尖，因此，刀位點(diǎn)不在圓弧上，而在該圓弧的圓心上；車(chē)刀圓弧半徑理論上與被加工零件的形狀無(wú)關(guān)，并可按需要靈活確定或測(cè)定后確認(rèn)。當(dāng)某些尖形車(chē)刀或成型車(chē)刀（如螺紋車(chē)刀）的刀尖具有一定的圓弧形狀時(shí)，也可作為這類(lèi)車(chē)刀使用。圓弧形車(chē)刀可以用于車(chē)削內(nèi)、外表面，特別適宜于車(chē)削各種光滑連接（凹形）的成型面。數(shù)控加工刀具生產(chǎn)過(guò)程中，刀具質(zhì)量測(cè)量的依據(jù)為刀具耐用度。四川數(shù)控機(jī)床刀具</p><p
