The drill described in the publication of No. 3 moves the taper portions facing each other vertically with respect to the plate glass of the hole formed by the drill, and efficiently applies the thread surface to the opening edges of the front and back surfaces of the glass plate. However, the target is only single glass, and the holes for attaching windshields for vehicles, for example, wipers to be laminated on laminated glass laminated with polyvinyl butyral interlayer film, are chamfered on both front and back sides. Although the laminated single glass is polymerized through the interlayer film, the laminated glass that has been polymerized has a problem that it causes hole misalignment due to concentric defects and interferes with the installation of wipers, etc. A drill was also developed, but the chamfering of the opening edge that joins the glass plate and the intermediate film has been omitted, and it is possible to remove small cracks or chips at the opening edge of the intermediate film and adhesion. A problem that results in anxiety on the degree there was.

経年劣化による白濁を防止することができる。The operation of the present invention will be described below. A laminated glass 3 perforated on a pedestal (not shown) which can be fixed is set, and cooling water is sprayed to the perforated part 4 of the laminated glass by other means through a shank 6 to a rotating part of a machine tool (not shown). The chamfering drill 5 which is mounted and rotating is inserted, and the drill is drawn to form an enlarged circumferential orbit, and the inner wall surface of the perforated portion 4, that is, the bead portion 9 of the drill is enlarged to the position where it abuts the interlayer film 2 of the laminated glass. If the taper portion 7 and the taper portion 8 are rotated while rotating with respect to each other, the downward taper portion 7 and the upward taper portion 8 are brought into contact with the front and back surfaces of the perforated portion 4 of the laminated glass, that is, the opening edges to be chamfered and contact the intermediate film 2. The beaded portion 9 also has a chamfering drill 5 that abuts the inner wall surface of the glass plate 1, 1 of which the bulge portion is adhered to the intermediate film by polishing one side edge together with the intermediate film 2 into a U shape. In the center of the perforated part 4 When the chamfering drill is moved back up, the perforated part 4 formed in the laminated glass is provided with finishing parts 10 and 10 on the front and back opening edges thereof, and a glass plate 1 and one surface to be bonded to the intermediate film 2 are attached. A polishing part 11 is also formed on the side, and the perforated part 4 of the laminated glass is formed by the polishing part and the finishing part 11 by polishing the chippings and minute cracks generated during the drilling due to the finishing of the opening edges of the glass plates 1, 1. As a result, the perforated portion 4 having the same concentric hole diameter of the glass plates 1 and 1 does not hinder the attachment in the next step, and the polishing portion 11 is coated with a resin such as silicon. It is possible to prevent white turbidity due to aged deterioration of the intermediate film 2 due to infiltration of rainwater or the like.

でもよい。The chamfering drill 5 of the drilling portion 4 is a combination of the rotation of the drill itself and the revolution of drawing a circular orbit, but instead of revolving, the chamfering drill 5 that rotates the laminated glass 3 and rotates is used. It may be a linear motion in which it contacts the peripheral wall surface.

At the same time, it can be efficiently deleted to eliminate the decrease in strength generated from the perforated part, and by coating or injecting resin into the polishing part, it is possible to prevent clouding due to aged deterioration generated from the perforated part.
Trouble in the next process can be eliminated by the concentric hole with the same diameter.
