Antique Glass Mirror Punching Method And Requirements
2022-12-02
Glass is familiar to everyone in our life, and it is widely used. Glass has been applied to various occasions. I believe many friends can also see that all kinds of glass need to be punched. Then Antique Mirror punches holes. What are the methods and requirements? Let's find out together! 1. Operation method: According to the thickness, size, and edge processing requirements indicated on the punching order, it is determined that the glass can be punched, and the glass needs edge processing (including edge grinding and chamfering) before drilling. 2. Review the order: Determine the glass drill bit that should be used according to the order requirements, and install it on the drill bit. 3. Punching operation: first place the glass that needs to be punched flat on the punching table, and mark the exact position to be punched with a carbon pen according to the hole position of the order. The marked position must be accurate and correct. After the completion, it is best to use the box ruler to calibrate and confirm that it is correct before drilling. Before drilling, first use the bearing ring to surround the hole and add a certain amount of water (water must be added when drilling, the purpose is to prevent the glass cloth from bursting during drilling, without any damage. The water drill hole will generate heat due to friction and the glass will expand (the glass will burst), then tilt the rotating drill bit and slowly align it with the drawn circle. Shake (shaking is to increase the distance between the holes and the drill bit is easy to withdraw after drilling through the glass). Drill down with force. Control the force according to the thickness of the glass. The thinner the glass, the smaller the force, and the thicker the glass, the greater the force. Pay attention When the glass is about to be drilled through, the force should be reduced and the hole should be drilled slowly. If the force is not reduced, the glass will have a large edge burst due to excessive force and affect the use of the glass. 4. Occurrence of edge bursting in drilling: Generally, there is no edge bursting or a small edge bursting on the lower drill bit surface. Generally, edge bursting occurs on the opposite side. The main reason is that the force is not reduced when the drill is about to penetrate, causing the glass to be drilled through quickly. At the moment when the glass is drilled through, there is a part of the link that is not because of the drilling, but the remaining point is squeezed out with a lot of force, so that the edge of the hole and the edge of the glass appear. 5. Remove the hole and remove the hole: draw the correct position first, and then drill holes at each corner, generally drill a hole with a diameter of 22mm or determine the diameter according to the situation, then wipe off the water on the removed part, and then cut it with a glass knife And knock it through, and then use a glass cutter to saw it off. When sawing the glass, you need a miter saw, and isolate an empty saw. 6. Pay attention to the smoothness of the table surface on the drilling operation table to prevent the glass from bursting when drilling holes. The above explanation is about the method and requirements of glass punching, and it needs to be helpful to everyone. If you are interested in Silver Mirror, you can also contact us.
