切削加工:镗削 用旋转的单刃镗刀把工件上的预制孔扩大到一定尺寸﹐使之达到要求的精度和表面粗糙度的切削加工。镗削一般在镗床﹑加工中心和组合机床上进行﹐主要用于加工箱体﹑支架和机座等工件上的圆柱孔(见图镗圆柱孔示意图 )﹑螺纹孔﹑孔内沟槽和端面﹔当采用特殊附件时﹐也可加工内外球面﹑锥孔等。对钢铁材料的镗孔精度一般可达IT9～7﹐表面粗糙度为R2.5～0.16微米。 镗削时﹐工件安装在机床工作台或机床夹具上﹐镗刀装夹在镗杆上(也可与镗杆制成整体)﹐由主轴驱动旋转。当采用镗模时﹐镗杆与主轴浮动联接﹐加工精度取决于镗模的精度﹔不采用镗模时﹐镗杆与主轴刚性联接﹐加工精度取决于机床的精度。由于镗杆的悬伸距离较大﹐容易产生振动﹐选用的切削用量不宜很大。镗削加工分粗镗﹑半精镗和精镗。采用高速钢刀头镗削普通钢材时的切削速度﹐一般为20～50米/分﹔采用硬质合金刀头时的切削速度﹐粗镗可达40～60米/分﹐精镗可达150米/分以上。 对精度和表面粗糙度要求很高的精密镗削﹐一般用金刚镗床﹐并采用硬质合金﹑金刚石和立方氮化硼等超硬材料的刀具﹐选用很小的进给量(0.02～0.08毫米/转)和切削深度 (0.05～0.1毫米)高于普通镗削的切削速度。精密镗削的加工精度能达到IT7～6﹐表面粗糙度为R0.63～0.08微米。精密镗孔以前﹐预制孔要经过粗镗﹑半精镗和精镗工序﹐为精密镗孔留下很薄而均匀的加工余量。
