[0003] Title: THROUGH-HOLE FORMING METHOD, THROUGH-HOLE FORMING APPARATUS, AND METHOD OF MANUFACTURING GLASS SUBSTRATE PROVIDED WITH THROUGH-HOLE

[0004] Abstract: Disclosed is a through-hole forming method including a process of forming, by condensing and irradiating a laser beam onto an insulation substrate through a lens, a through-hole that passes through the insulation substrate in a thickness direction of the insulation substrate.

[0005] A medium between the lens and the insulation substrate is air. A converging half angle Q that is calculated from a focal length f of the lens and a beam diameter d of the laser beam that enters the lens by using expression satisfies expression.

Technical Problem

[0006] Following Tips should be considered while milling glass holes.

[0007] The diamond drill should be placed on the glass surface in a perpendicular manner. Otherwise, some issues like drill service life, drilling prolongation, making a bigger hole, and increased tension in the glass will be resulted.

[0008] As glass is characterized by high modulus of rigidity and is resistant to

abrasion, drill rotational speed must be very high to reduce abrasion rate for every drill rotation and to ensure drilling quality. The importance of this point is directly proportional to drilling progress in the glass, and as we get closer to the end of the drilling process, it will much more important to prevent glass hole fracture from below.

[0009] Drill feed rate should have descending trend, i.e. the more drill progresses in glass, the less feed rate will be so that both the probability of glass crushing is lessen and fracturing bottom hole of glass is prevented simultaneously. In addition, a slight feed rate is required to establish a relationship consistent with the high drill rotational speed and to prevent shortening its service time. The most important precondition for glass drilling (milling) is that surface of the glass and diamond drill should be permanently wetted, otherwise, glass milling will not be possible under other conditions. Diamond drill performance is heavily dependent on water, so that without wetting, drilling even a hole will be impossible.

Summary of Invention

[0010] Considering all the above-mentioned points, this device is designed to

minimize human error. Milling machine and its components are placed vertically on the glass and portability, is the main advantage of this machine.

[0011 ] Given that this machine is portable, all components are mounted on the

chassis and designed in such a way that it does not interfere with the machine operation in case of displacement.

Description of Embodiments

[0015] The machine consists of a chassis (1 ), whose lower part is mounted on the glass (2). The user can adjust machine height to the glass with two handles (3). Setting the height in this manner determines feed rate or propulsion force.

[0016] The diamond drill (4) is attached to the milling machine and comes in contact with glass through two parts of chassis. The water tank (5) embedded in the machine transfers water to the glass. Several rubber gaskets (6) have been installed under the chassis to keep the water in place. [0017] A spring (7) supplies force required to apply the pressure to the drill. The use of a spring prevents the user from sudden compressing on the glass as it can be led to glass fracturing. On the rear part of the machine and under the water tank, there is a valve (8) that allows the user to pour water out of the hose (9) into the water pond (10). Gaskets keep the water in the ponds until the milling operation is performed properly. Also, this method prevents wasting water.

Invention advantages

[0018] 1. Portability

[0019] 2. Fixing the machine vertically on the glass

[0020] 3. Applying feed rate as per drilling progress in the glass

[0021 ] 4. Providing water with the least water wasting

Method for applying the invention

[0022] First, we attach the diamond drill to the machine using a fixed wrench

mounted on top of the chuck.

[0023] Then, given the drill bit diameter, the machine stands are set in required state, that is, if we use the largest diamond drill bit, because of the need for more feed rate, the stands are set on grade 4 and if they should be used with the smallest drill bit due to the need for less feed rate, we can set the stands to grade 1. The high grade number, the less drill feed rate is.

[0024] In the high feed rate position i.e. Grade 4, the diamond drill will have the

largest projection from bottom of the machine, so that machine is fixed on the glass surface and the leveling of the drill bit with the machine, the highest potential energy will be stored in spring shaft.

[0025] After adjusting, the machine feed rate can be set into coordinates using

coordinating clamps. The pressure exerted from the machine weight on elastic washers completely seals pond, then we open relief valve embedded in the bottom of the machine to fill to pond and then close it. Then while holding handles by two hands, we turns it on. [0026] Hence, milling will be started in automatically manner whiteout exerting feed rate in high quality and safety regardless of drill verticality and end moments of milling and drilling.
