刀具:深孔钻 专门用於加工深孔的钻头。在机械加工中通常把孔深与孔径之比大於6的孔称为深孔。深孔钻削时﹐散热和排屑困难﹐且因钻杆细长而刚性差﹐易產生弯曲和振动。一般都要藉助压力冷却系统解决冷却和排屑问题。深孔钻按排屑方式分为外排屑和内排屑两类。外排屑的有枪钻﹑深孔扁钻和深孔麻花钻等﹔内排屑的因所用的加工系统不同﹐分BTA(Boring and Trepanning Association)深孔钻﹑喷射钻和DF(double feeder)深孔钻3种(见图 几种不同的深孔钻 )。枪钻﹕只有一个切削部分﹐最早用於加工枪管。钻削时﹐切削液从钻杆中间进入﹐经钻头头部的小孔喷射到切削区﹐然后带著切屑从钻头的V形沟槽中排出。枪钻适用於加工孔径2～20毫米﹑孔深与孔径之比大於100的深孔。BTA深孔钻﹕切削液从钻杆与孔壁的间隙处送入﹐靠切削液的压力将切屑从钻杆的内孔中排出。BTA深孔钻适用於钻削孔径6毫米以上﹐孔深与孔径之比小於100的深孔﹐其生產效率比枪钻高3倍以上。喷射钻﹕一种多刃内排屑深孔钻﹐有内﹑外两层钻管﹐大部分切削液从内﹑外钻管的间隙中进入切削区﹐然后连同切屑进入内管﹔另一小部分切削液则经由内管尾端的月牙形孔进入内管﹐產生喷射效应﹐形成低压区﹐帮助抽吸切屑。喷射钻不要求严格的切削液密封装置﹐适用於钻削直径18毫米以上﹑孔深和孔径比小於100的深孔。DF深孔钻﹕这种钻头吸收了BTA深孔钻和喷射钻的优点﹐採用单管﹐排屑靠推压和抽吸双重作用﹐提高了排屑能力﹐可钻削孔径在8毫米以上的深孔。 枪钻常用高速钢或硬质合金製造。各类内排屑深孔钻可根据尺寸大小﹐採用焊接或机械夹固式可转位硬质合金刀片的结构。深孔钻上的导向块起导向和定心作用﹐减少钻孔的偏斜和切削时的振动。深孔钻的刀齿和导向块的布置主要考虑分屑和切削时径向力的平衡。刀体与钻杆可用焊接或方牙螺纹联接。
