镗削工具的结构如图所示。镗杆a的前端装有互成180°的两个刀头b,每个刀头上带有刀片c。这种镗削工具的特点是,镗杆a的端面上全部切出平行的三角齿纹d;与此相应,在刀头b的底面也切出同样的齿纹。因此,刀头b与镗杆a是通过三角齿形来互相咬合的,安装既简单又可靠。刀头b上开有长槽f,只
Boring tool structure as shown. The front end of the boring bar a is equipped with two heads b which are 180 ° to each other, each with a blade c. This boring tool is characterized in that all of the end faces of the boring bar a are cut out in a parallel triangular pattern d; correspondingly, the same pattern is also cut out on the underside of the tool b. Therefore, the head b and boring bar a are engaged with each other through the triangular profile, the installation is simple and reliable. Tool head b has a long groove f, only
