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）、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Ra2.5～0.16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Ra0.63～0.08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。
