[0002] A drilling machine generally refers to machinery and equipment that uses a tool harder and sharper than the target object to leave a cylindrical hole or cavity on the target object by means of rotary cutting or rotary extrusion. It is also called a drilling rig, a punching machine, a hole-making machine, a through-hole machine, etc. By drilling precision parts, the expected effect can be achieved. With the development of the times and the improvement of the drilling technology of automatic micro drilling machines, the use of fully automatic micro drilling machines has obvious advantages in high-precision drilling of various hardware molds, watchbands, jewelry, etc.
