て穴明は加工を行うのである。Since the present invention has the above-described structure, first, the drill spindle 3 is rotated by the motor 2 in response to a start signal. Next, the quill 5 holding the drill spindle 3 is rapidly moved forward by the hydraulic cylinder device 4. As the quill 5 moves forward, the step cam 8 and dog cam 10 fixed on the front door also move forward. At this time, step cam 8
is regulated by a cam roller 11 engaged with the step cam groove 9, and moves forward and rotates following the step cam groove 9. Also, due to the rotation of the step cam 8, the dog cam 10
also rotate in the same phase, actuate the hydraulic flow regulating valve 12 to regulate the hydraulic flow to the hydraulic cylinder device 4, switch the drill spindle 3 to cutting feed, and maintain the feed rate within the dog face length range. Then, the forward end of the drill spindle/I/3 is confirmed by the limit switch 13, and the quill 5 is rapidly forwarded and retreated. When the quill 5 moves back and forth rapidly, the step cam 8 rotates backward while being regulated by the cam roller 11, and at the same time the dog cam 10 rotates in the same phase to switch to the next step position. By performing such an operation for the number of steps, as shown in Fig. 4,
Fast forwards to the previous cutting position and switches to cutting feed,
After cutting to a predetermined depth, the hole is drilled by sequentially repeating fast return.

。In this way, in the device of the present invention, the means for switching from rapid feed to cutting feed in several stages of step feed is a step cam that moves forward and backward in conjunction with the forward and backward movement of the tile and rotates. It has a simple mechanism with a dog cam that advances and retreats in the same phase as the step cam and rotates to control the hydraulic flow rate adjustment valve of the hydraulic cylinder device.Moreover, it can be provided at low cost because it does not require special power or interlocking conversion equipment. In addition, there is an advantage that maintenance is easy.
