如图所示,是一种高效锪孔刀,可在孔背面进行锪孔、倒角、锪平面等操作。锪孔刀由刀杆6和回转刀排5两部分组成。回转刀排5由支承螺钉2固定在刀杆6的凹槽处,并可在一定范围内转动。进行锪孔操作时,将回转刀排5折转入刀杆6的凹槽内,刀杆6即可伸进工件的孔中。当刀杆6随主轴旋转时,在离心力的作用下,回转刀排5转到工作位置,即可进行锪孔。操
As shown in the figure, it is a kind of high efficiency hole cutter, which can be used to drill holes, chamfering and flat surface on the back of the hole. Hole cutter by the cutter bar 6 and rotary knife row two parts. Rotary knife row 5 by the support screw 2 is fixed in the groove of the arbor 6, and can be rotated within a certain range. For countersink operation, the rotary knife 5 fold into the groove 6, the arbor 6 can be inserted into the workpiece hole. When the arbor 6 rotates with the spindle, under the action of centrifugal force, the rotary knife row 5 is turned to the working position, then the counter-bore can be performed. Fuck
