摘要： A rotatable cutting tool has a shank portion for coupling to a tool driving device and a cutting portion to which is attached at least one support member for retention of a replaceable cutting element. The support member is so arranged to permit displacement of at least the portion thereof retaining the cutting element whereby the position of the cutting element relative to the body of the cutting tool may be changed by such displacement. A totally enclosed hydraulic force multiplier is mounted within an internal cavity of the cutting tool. The force multiplier is responsive to a control force to effect the displacement of the support member, the control force advantageously supplied by application of pneumatic pressure.

摘要翻译： 可旋转的切削工具具有用于联接到工具驱动装置的柄部和切割部分，至少一个支撑构件附接有切割部分以用于保持可更换的切割元件。 支撑构件布置成允许至少其部分保持切割元件的位移，由此切割元件相对于切割工具的主体的位置可以通过这种位移而改变。 一个完全封闭的液压力倍增器安装在切割工具的内腔中。 力倍增器响应于控制力来实现支撑构件的位移，该控制力有利地通过施加气动压力来提供。
