How to make a hole in the glass: ways and instructions

The creation of holes in the glass may seem like a simple operation, but in practice it is quite a complicated and responsible procedure. The structure of the glass is malleable for machining, but it is very fragile. Therefore, the peculiarity of the operation is not so much in the choice of the force of influence as in the approach to its organization. The main task of the master is not to lead to the formation of cracks, chips and fractures of the main surface. How to make a hole in the glass without violating this condition? You can accomplish this task with the help of special technologies and tricks that are available to almost any master. Next, the most popular and effective methods will be considered.

Preparation of glass for processing

Before any hole-making operation or simply cutting, appropriate preparation should be carried out. The working surface of the glass should be clean and, if possible, do not have defective areas - during drilling they can give a third-party chip that will spoil the workpiece. It is recommended to mark the lines of the future hole so that the physical flaws of the surface are inside the circle, but do not go beyond. As an additional measure, it is possible to treat glass and chemicals, which, in particular, will relieve it of oil marks. If there is a question about how to make a hole in a small glass, you will have to prepare and fixing the rigging. The method of fixing the workpiece will depend on the technology of creating the hole, but in most cases such elements are attached to the vice of a suitable configuration - a damping soft material is directly placed in the contact areas.

Nuances of drilling holes

It is not possible to process glass by a conventional drilling method. If we are talking about harvesting the same small dimensions, then we can use a standard set of drills and drills, but before that, the working tool should be prepared in a special way. First of all, a suitable size drill is heated to a white shade. Then it must be immersed in the sealing wax and held until the latter melts. After that, the tip is wetted in turpentine and you can start the work process. There is another option that allows you to make a round hole in the glass by drilling - its step-by-step instruction is presented below:

• Camphor and particles of coarse-grained sandpaper are crushed.
• Prepared elements poured into a small container and diluted with turpentine.
• A small piece of copper wire is prepared for the drill, which must be clamped in the cartridge.
• Prepared pasta is laid on a cleaned glass surface.
• To position the copper tool, a guide conductor from plywood is prepared.
• You can start drilling.

Creating large holes

The drilling methods are not always theoretically permissible for making holes in the glass, and not only because of the high risk of formation of the same chips. In the case of holes with a diameter of more than 10 cm, this task can not cope with any household equipment. But in this case there is a way out, in which a drill is also involved. It is necessary to make a small through point in the prepared surface in the very center of the planned hole. To do this, you can use any small-format glass with a diameter of less than 1 cm. Do not be afraid of third-party chips, because they will come to the square, which will be already removed. Now another question: how to make a hole in the glass, having in the center a small through hole? A piece of wire is inserted into the created small hole and fixed. The other end is fastened to the glass cutter. Further, after checking the reliability of the fixation of the elements and the smoothness of the tool stroke in a circle, you can start cutting along the circumference.

Fusing a hole

In this case, it will be necessary to initially prepare a tool for the preparation of liquid tin or lead. A glass surface is prepared accordingly. It should be treated with gasoline, acetone or alcohol. Next, the moistened sand pours out onto the marked zone of hole formation. It should be so large that you can create a funnel, the bottom of which in size will fit the edges of the hole. After that, metal is poured into the created funnel. It will cool down in 1-2 minutes, after which it will be possible to remove the sand snap along with the mold. This is the best option if the question is relative how to make a hole in the glass without a drill and with even edges. But the problem can arise in another aspect. No matter how accurate the funnel made of sand, it will be impossible to control the diameter that will form when metal is glazed with glass.

Cutting with a soldering iron

This option from the point of view of the quality of the result can be called the opposite of the previous one. In this case, the master will be able to relatively accurately withstand the boundaries of the marked hole diameter, but the edges may be uneven. The process begins with the creation of risks with the help of a file. The task of this operation is to carefully mark out the depth for the future melting of the soldering iron. Now you can proceed to the next stage - how to make a hole in the glass without drilling with a soldering iron? After warming up the sting of the machine, you can start cutting. And hurry in this process should not be. It is advisable to carry out the felting with small pieces, if necessary, cooling the glass - otherwise there is a risk of deformation and the areas not provided for processing.

How to make a hole in a heat-resistant glass?

It is a very laborious operation, and in such situations the limitations in methods, caused by the fragility of ordinary glass, no longer matter. In some ways, this cutting is similar to the treatment of metal surfaces. If it is a question of thin glass, then it is possible to try drilling with the use of diamond and solid-state nozzles. In any case, they cope with the metal. But how to make a hole in a large diameter glass? To do this, you can use a powerful perforator with a crown equipped with the same diamond elements. As an alternative, you can try and cut with an abrasive wheel, but it will provide a very rough result, which is not always the case.

High-tech processing methods

This category of methods for creating holes is more likely to be industrial, although private craftsmen for their needs acquire appropriate equipment. We are talking about lathes and aggregates that provide sandblasting abrasive cutting. The most qualitative result is given by hydroabrasives - how can one make a hole in glass using such equipment? First, the installation is fixed in the machine clamps - there are practically no restrictions on the dimensions, including the thickness. The consumables are then refilled. They are sand and water. The hole is created as a result of circular cutting by a water-sand jet along a previously planned line. Automation itself will position the direction of the cut, providing an almost perfectly flat cut.

Conclusion

The fragility of the material significantly limits the home masters who need to make a hole in it. Nevertheless, almost every traditional way of forming round cuts, provided that the improvement is obtained, is also effective in solving this problem. It is possible to make a hole in the glass at home using a drill, a glass cutter or a soldering iron. Another thing is that the quality will not always meet the expectations. Nevertheless manual processing always assumes risks of deviation from the cutting direction. If the diameter does not have a particular value, then you can refer to the method of smelting - at least, it allows you to count on the smoothness of the edge. If you want a high-quality hole, and made in tempered glass, then without special equipment will not be able to do.
