[0015] 2. The hole processing machine tool used for parts processing can ensure the main motor and the boring machine to slide smoothly forward and backward on the upper end of the slide by means of the screw to horizontally guide the servo motor on the slide, and utilizes the fitting arrangement of the right-angle plate portion on the upper end of the T-shaped plate at the lower right corner of the U-shaped rail to enable the T-shaped plate to provide a stable traction force on the left side of the boring machine, thereby preventing the axis of the boring machine from deviating to the right under the action of its own weight after long-term use, and can always ensure that the boring machine is on the central axis of the drilling processing, thereby ensuring that the hole processing axis of the boring machine remains unchanged during long-term use.

[0016] 3.

According to the principle of Lenz's law, the iron chips are light in weight relative to the drill rod and have little adhesion to the drill rod. When the iron chips attached to the drill rod follow the drill rod through the first elliptical ring and the second elliptical ring, they are blocked by the magnetic flux and collected in the bucket groove, thereby automatically cleaning and collecting the iron chips attached to the drill rod to prevent the iron chips from affecting the accuracy and size of the secondary drilling.

[0017] 4. The hole processing machine tool used for parts processing can solve the problem of insufficient flushing of iron chips caused by the traditional cooling pipe when flushing the drill rod.
