A drilling apparatus has a work robot mounting a drilling blade and moving inside a main pipe and a photodetector for detecting the contour of an opening image formed on the inner surface of a pipe lining material by illumination light. The opening image is scanned, and a two-dimensional image corresponding to the opening image is generated based on the contour points P0 to P8 detected by the photodetector for display on a display unit. The amount of positional deviation between the center of the two-dimensional image on the display unit and the axial center C of the rotary shaft of the drilling blade is calculated, and the pipe lining material is drilled by moving the drilling blade by the amount of positional deviation in a direction in which the positional deviation is eliminated.

Disclosed herein is an apparatus for processing a substrate that forms a hole in a substrate while reducing a burr in the hole so that a module device can be inserted into the hole to reduce the thickness of a display device, and the display device using the apparatus. The apparatus for processing the substrate comprises a body configured to operably be rotatable, and a cylindrical cutting tip at an end of the body. The bottom surface of the cutting tip is in an acute angle with respect to a contact surface of the substrate to allow formation of a groove at the substrate.

The invention discloses a mailbox punching device, comprising a baseplate, two frames which are correspondingly arranged at two ends of the top of the baseplate, and a box arranged between the two frames on the two ends through a lifting device. The inner bottom of the box is provided with a first steering cavity with an opening facing downward, and a second steering cavity extends vertically in the box above the first steering cavity. A first sliding groove is connectedly set on one inner wall of the second steering cavity, and a steering platform, through bearings, is rotatably mounted in the first steering cavity. A first steering shaft, which extends into the second steering cavity, is fixedly arranged on the top of the steering platform, and a first bevel gear is fixedly mounted on the first steering shaft in the second steering cavity.
