为了加工凹槽设计了一种工具,这个工具利用外套内刀套的滑动使刀杆活动。用于与此工具相连接的装置使工件同钻套发生联系,以挡住刀套上的止动环。由于刀具被扣紧在刀套上,刀具伸入工件的深度D由套上的止动环的位置确定。当衬套与止动环接触时,在刀杆和外套之间的凸轮机构开始联动。于是刀具绕梢轴旋转并开始切削凹槽。 In order to process the groove, a tool is designed which uses the sliding of the sleeve inside the jacket to move the cutter bar. The tool used to attach the tool connects the workpiece to the drill collar to block the stop ring on the tool holder. Since the tool is clamped to the tool holder, the depth D of the tool into the workpiece is determined by the position of the retaining ring on the cover. When the bushing is in contact with the stop ring, the cam mechanism between the arbor and the cover starts to interlock. The tool then rotates about the shaft and begins to cut the groove.
