數控機床銑刀(dao)的選用

2025-12-26

　　數控機(ji)床硬質台金可(ke)轉位式面銑刀(dāo)主要用于銑削(xuē)平面。粗🔞銑時，銑(xi)刀直徑選小一(yī)些，因爲粗銑時(shí)切💘削力大，選小(xiao)直徑銑刀可💋減(jiǎn)小切削力矩。數(shu)控機床精銑時(shi)，銑刀直徑選大(dà)一些，最好能包(bao)容待加工面⭐的(de)整個寬度，以提(tí)高加T精度和效(xiao)率。機床加工餘(yú)量🈲大且不均勻(yún)時，刀具直徑應(yīng)選小一些，否則(zé)，會因挂刀刀痕(hén)過深而影響工(gong)件的加丁質量(liàng)。

　　高速鋼立銑刀(dāo)多用于加工凸(tū)台和凹槽，一般(bān)不用來👣加工毛(mao)坯表面，因爲毛(mao)坯表面的硬化(hua)層和夾砂會加(jiā)快刀具磨損。

　　加(jia)工毛坯表面或(huo)粗加工孔時，可(kě)選鑲硬質合金(jin)的🥵立銑刀或玉(yu)米銑刀進行強(qiang)力切削。

　　加工平(píng)面工件周邊輪(lun)廓時，常采用立(lì)銑刀C。

　　加工(gōng)立體曲面或變(bian)斜角輪廓外形(xíng)時，常采用球頭(tou)銑刀、環形銑刀(dāo)、鼓形銑刀、錐形(xíng)銑刀、盤形銑刀(dao)等。

　　當加工餘量(liang)較小，且表面粗(cū)糙度要求較高(gāo)時，可選用鑲立(li)🌍方😄氮化硼刀片(pian)或鑲陶瓷刀片(piàn)的面銑刀，以便(biàn)能進行❤️機床高(gāo)速切削。
