德国Walter Bauer工程师开发出一种孔加工刀具,这种刀具既可用来镗孔,又可在镗孔之后对孔的入口处和出口处进行倒角,从而可减少切削中断时间和刀具数量。 采用一把刀具实现镗孔和倒角,这是通过一种特殊的刀夹来实现的。在这种刀夹中装有一个偏心摆动装置,而切削刀具则装在 Walter Bauer engineers in Germany have developed a hole machining tool that can be used both for boring and for chamfering the entrance and exit of holes after boring to reduce cutting interruptions and the number of tools. Boring and chamfering with one tool is achieved with a special toolholder. In this tool holder is equipped with an eccentric swing device, while the cutting tool is installed
