る。 When counterboring the back side of a workpiece using a radial drilling machine, an operator inserts a cutting tool into the backside of the workpiece, which has a narrow space, and connects it to the spindle.
In this case, it is necessary to set up and take out the cutter every time processing is carried out, which has the drawback of extremely poor workability. Also,
There are special tools that pass through a hole in a workpiece in a closed state and open when the spindle is rotated to perform counterboring, but they are not durable and are expensive.

Ｗの裏ざぐり加工を行うのである。 In the above state, the column 2 moves forward in response to a command to start counterboring, and is stopped at a position where the cutting tool 13 held by the cutting tool holding member 12 corresponds to the countersinking position of the workpiece W. Next, the first movable body 5 is moved downward, and the lower end of the first movable body 5 is brought into contact with the upper end of the second movable body 6. As a result, the tip of the spindle 10 passes through the hole in the workpiece W, and the protruding shaft 14 fits into the hole 15 in the cutting tool 13. Thereafter, when the motor 11 is started and the spindle 10 is rotated, the cutting tool 13 is rotated because the projection shaft 14 and the hole 15 are fitted in an elliptical shape. By moving the second moving body 6 upward, the first moving body 5 is also moved upward, maintaining the fitting relationship between the protrusion shaft 14 and the hole 15, giving cutting feed to the cutting tool 13, and machining. This is to counterbore the back of the object W.

The workpiece W is indexed and the machining operation described above is repeated.

省エネルギ化が図られる。 As described above, according to the present invention, the cutting tool connected to the spindle at the countersinking position is automatically moved in and out by the cutting tool gripping member, and is automatically inserted into and removed from the spindle. As such, there is no need for the operator to carry out loading/unloading operations each time, which has the advantage of improving work efficiency and saving labor. The cutting tool holding member is guided so as to be movable up and down on the front surface of the column, and is fixed to a second moving body that moves up and down by a dedicated actuating device, so that the cutting tool held by the tool holding member can move up and down during the second movement. Precise cuts are made into the workpiece by the feed movement of the body, making it possible to carry out heavy counterboring.The spindle that engages the cutting tool only handles the rotational movement of the cutting tool, and no load is applied in the axial direction. , the durability of the spindle bearing is ensured, and the actuating device of the first movable body can be made small and energy saving can be achieved.
