[0002] A drilling machine is a general term for machinery and equipment that uses a tool that is harder and sharper than the target object to leave a cylindrical hole or hole on the target object through rotary cutting or rotary extrusion. It is also called a drilling machine, a punching machine, a hole-drilling machine, a through-hole machine, etc. There are semi-automatic drilling machines and fully automatic drilling machines. With the increase in human resource costs, most companies are considering fully automatic drilling machines as their development direction.

[0003] In existing drilling equipment, the effect of drilling a hole or a through hole on the surface of a workpiece is generally achieved by rotating and lifting the drill bit.
