三面刃銑刀端齒分類和加工方法
來源:京珂機械   時間::2021-01-03     點擊次:
  三面刃銑刀:主要用于銑削定值尺寸的凹槽,也可銑削一般凹槽、臺階面、側面。特點及度:與普通銑刀不同,三個刃口均有后角、刃口鋒利、切削輕快。刀體40Cr,刀片為硬質合金;加工鑄鐵采用K20(YG6),加工鋼件采用P20(YT14)。端面靠近外圓的部位都有切削刃較寬鋸齒狀;三面刃銑刀的主切削刃分布在銑刀的圓柱面上,副切削刃分布在兩端面上;可調可轉位硬質合金錯齒三面刃銑刀來加工溝槽,既可補償刀片磨損后的寬度尺寸的減小,又可減少銑刀寬度規格.若選擇適當的切削用量,各種溝槽可一次走刀銑成,度可達HS,光潔度可達好。具有效率高、壽命長、成本低、節約鋼材和便于瞥理等特點。
  
  三面刃銑刀除圓周表面具有主切削刃外,兩側面也有副切削刃,從而改善了切削條件,提高了切削效率和減小表面粗糙度。主要用中等硬度,強度的金屬材料的臺階面和槽形面的銑削加工,也可用于非金屬材料的加工,硬材料三面刃銑刀用于難切削材料的臺階面和槽形面的銑削加工。主要用于銑削定值尺寸的凹槽,也可銑削一般凹槽、臺階面、側面。
  
  分類:
  
  按齒型分類:分直齒和錯齒兩類。
  
  直齒的用于銑削較淺定值尺寸凹槽,也可銑削一般槽、臺階面、側面光潔加工。
  
  錯齒的用于加工較深的溝槽。
