补充资料:铰削
      利用铰刀从已加工的孔壁切除薄层金属,以获得精确的孔径和几何形状以及较低的表面粗糙度的切削加工。铰削一般在钻孔、扩孔或镗孔以后进行,用于加工精密的圆柱孔和锥孔,加工孔径范围一般为3~100毫米。由于铰刀的切削刃长,铰削时各刀齿同时参加切削,生产效率高,在孔的精加工中应用较广。
  
  铰削的工作方式一般是工件不动,由铰刀旋转并向孔中作轴向进给。在车床上铰削时,工件旋转,铰刀作轴向进给。铰削过程中,铰刀前端的切削部分进行切削,后面的校准部分起引导、防振、修光和校准作用。铰孔的尺寸和几何形状精度直接由铰刀决定。铰削可分粗铰和精铰,一般在车床、镗床或钻床上进行,称为机铰,也可手工铰削。粗铰的切削深度(单边加工余量)为0.3~0.8毫米,加工精度可达IT10~9,表面粗糙度为Ra10~1.25微米。精铰的切削深度为0.06~0.3毫米,加工精度可达IT8~6,表面粗糙度为Ra1.25~0.08微米。铰孔的切削速度较低,例如用硬质合金圆柱形多刃铰刀对钢件铰孔时,当孔径为40~100毫米时,切削速度为6~12米/分,进给量为0.3~2毫米/转。正确选用煤油、机械油或乳化液等切削液可提高铰孔质量和刀具寿命,并有利于减小振动。
