圆柱体内表面环形槽的加工,尤其是当内孔与环形槽的同轴度公差要求较高;环形槽精度等级也较高时,加工是比较困难的。这里介绍一种加工环形槽的工具,如图所示,把它装在卧式镗床的主轴上即可进行加工。加工前可将螺母5向右移动,杆4则处于自由状态,由于弹簧3和推杆2的作用,使刀头绕轴1转至虚线位置。刀杆进入圆柱孔内所确定的位置后,旋动螺母5,使其向左移
Cylindrical inner surface of the annular groove processing, especially when the bore and the annular groove coaxial tolerance requirements are higher; annular groove accuracy level is higher, the processing is more difficult. Here is a tool for machining an annular groove, as shown in the figure, mounted on the main shaft of a horizontal boring machine for machining. Before machining, the nut 5 can be moved to the right, and the rod 4 is in a free state. Due to the action of the spring 3 and the push rod 2, the cutter head is rotated around the axis 1 to the dotted line position. After the arbor enters the determined position in the cylindrical hole, turn the nut 5 to move it to the left
