制御器とを設けた穿孔機。 An electric drill with a cutter attached to the tip of the spindle and driven by a motor is supported on the front of the drilling machine body so as to be movable in the axial direction of the spindle, and a feed motor provided on the drilling machine body drives the electric drill. Advances into the workpiece and performs perforation with a blade,
A drilling machine that retracts the electric drill from the workpiece after drilling is completed includes a position detector that detects the upper limit position of the electric drill, and a position detector that detects the upper limit position of the electric drill, when the electric drill is automatically fed by the feed motor, immediately after the electric drill starts drilling, and when drilling is completed. A control system that detects the presence or absence and magnitude of a load on the drive motor of an electric drill at three points in time, and sequentially increases the speed of the feed motor of the electric drill in three stages: low speed, predetermined high speed, and higher speed. A drilling machine equipped with a container.
