Cutting glass is a difficult process in which you must be able to use a glass cutter. This process will help to replace various glass surfaces (windows, shelves, doors, etc.) on your own, without any outside help.
Glass cutting should be done on a flat surface with a cloth or sheet of paper.
To perform high-quality glass processing and properly cut glass with a glass cutter, you need to prepare a tool and auxiliary items:
- glass cutter;
- curve (ruler);
The table must be smooth, and the processed glass must be fully fit on it. If the glass area is large, even a small curvature of the table can lead to cracking of the material.
If you need to make a cut in a straight line, then you need to use the usual joinery line made of metal. In other cases, you will need a piece, with its help you can achieve different curved lines.
Next you should use a glass cutter. Visually, this tool looks like a canning knife. After examining its design, you can begin to cut the glass.
Patterns of movement of the glass cutter on glass.
To do this, hold the glass cutter on the cut surface, while making pressure on him. The pressure should be such that the cutter rollers are well cut into the surface of the material. The glass should not break or crack. If the cutting tool is of high quality, then it’s enough to hold it once. In the opposite case, the cut must be made yet. After that, you need to knock lightly on the glass and manually break off the cut edge.Back to table of contents
Performance of work
Before you cut the glass, you must mark it. For this, the start and end points of the line are marked. Then with the help of a ruler or patterns on them is the desired line. It should be borne in mind that the cutting line should be 1-2 mm further than the intended cut. This is due to the fact that the glass cutter has a certain thickness of the rollers, which must be corrected in size. In order to make sure exactly what amendment is required, you need to circle a small line with a cutting tool along the ruler. Then you will see the magnitude of its error.
In order to properly cut the glass, it is necessary to pass the cut line at one time, while not stopping and moving the tool. The thrust should be the same along the line of the whole movement. Cutting speed should be fast and uniform.
Receptions cutting glass line.
A ruler or a curve should not have excess flows for which the tool will be hooked. This may prevent a high-quality cut glass, due to the fact that the force of pressure will be uneven.
The quality of the passage of the tool rollers can be judged by the sound during the execution of work. The sound should be uniform, without clicks and claps. The presence of these signals may indicate excessive pressure.
Going to the edge of the glass, you need to slightly loosen the pressure and unscrew the head (close your eyes).
This will help prevent injury if the glass cutter slips off the edge and causes small fragments to appear.Back to table of contents
After the cutting line is drawn, it is necessary to assess its quality. Where there is a line break, it needs to be cut. Places with a gap need to connect in one line, avoiding its fractures. When the material is being broken, more attention should be paid to this place.
Then, when the thickness of the processed glass will be 4 mm or more, and the cutting line will not be very good, then you need to do a little differently. It is necessary to bring the line beyond the edge of the table by 5-6 cm so that it is in limbo. Next, you need to use a lightweight hammer to knock along the prepared line. The working edge of the surface of the hammer should be slightly rounded. Strikes them should be applied on the bottom plane very carefully, so as not to break the glass. If such a tool could not be found, then you can use an ordinary wrench size 13x14.
Beats must be done until a crack appears. Next, you need to gradually move along the entire length of the line. If the chip does not happen on the applied markup, then this can be corrected by striking the key from the opposite edge of the chip. At the same time, it is necessary to observe that the part being cut does not fall to its feet. To avoid this, with the second hand and with one knee it is necessary to hold the cut edge.
It is necessary to be prepared for the fact that it is not the first time that the glass cutter can cut the glass correctly. In order to perform such work qualitatively, it is necessary to practice a little on unnecessary glass trimming.
