Requirement & Method of Punch Glass

1. Operation method:
First, according to the thickness, size and edge processing requirements that need to be punched, as indicated on the punching order, determine that the glass can be punched. The glass needs to be treated at the edge (including edge grinding and chamfering) before punching.

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, lay the glass that needs to be punched flat on the punching countertop. According to the order hole position, mark the exact position to be punched with a carbon pen. The marking position must be accurate and correct. After the annotation, it is best to verify that it is correct with a box ruler before drilling. Before drilling, use a bearing ring to circle the hole and add a certain amount of water (when drilling, water must be added. The purpose is to drilling, the glass cloth will burst when drilling, and the anhydrous drilling will cause heat glass expansion due to friction). Then tilt the rotating bit slowly aim at the drawn circle. The edge of the drill bit close to the marked edge of the drill bit first, and then slowly stand upright and shake (shake to increase the hole distance from the drill bit is easy to

4. Appearance of drilling edges: Generally, there is no explosion edge or a smaller edge in the lower drill surface. Generally, the edge of the head occurs on the opposite side. When it is about to drill through, no attention is reduced force, resulting in the rapid drilling of glass. At the moment of glass drilling, the link part is not squeezed out the remaining point with great force because of drilling off, and the edge of the hole appears on the edge of the glass.

5. Remove the hole: also draw the correct position first, and then drill holes in each corner now. Generally, drill the diameter of 22mm or determine the diameter hole according to the situation, then wipe the water from the removed part above, then cut it with a glass knife and knock it through, and then cut the glass to cut the saw. The saw glass should be obliquely inserted to isolate an empty saw.

6. Pay attention to the flatness of the countertop on the punching operation platform to prevent the glass from bursting when punching holes and removing holes.
