style="text-indent:25px">銑刀的角度及選擇原則技巧：主偏角κr主偏角為切削刃與切削平面的夾角，如圖9所示。銑刀的主偏角有90°、88°、75°、70°、60°、45°等幾種。主偏角對(duì)徑向切削力和切削深度影響很大。徑向切削力的大小直接影響切削功率和刀具的抗振性能。銑刀的主偏角越小，其徑向切削力越小，抗振性也越好，但切削深度也隨之減小。90°主偏角，在銑削帶凸肩的平面時(shí)選用，一般不用于單純的平面加工，蘇州骨釘銑刀加工。該類刀具通用性好（即可加工臺(tái)階面，又可加工平面），在單件、小批量加工中選用。由于該類刀具的徑向切削力等于切削力，蘇州骨釘銑刀加工，進(jìn)給抗力大，易振動(dòng)，因而要求機(jī)床具有較大功率和足夠的剛性。在加工帶凸肩的平面時(shí)，也可選用88°主偏角的銑刀，蘇州骨釘銑刀加工，較之90°主偏角銑刀，其切削性能有一定改善。主軸上刀具的懸伸量盡可能達(dá)到短，減小銑刀軸線與工件位置對(duì)沖擊載荷的影響。蘇州骨釘銑刀加工</p><div
