When looking at experienced glass cutters, the thought involuntarily arises that it is very easy to use a glass cutter. But having tried to cut the glass themselves, many come to the opposite opinion and are disappointed in their own abilities. However, do not do this ahead of time. Using this tool is easy if you know some simple cutting features.
The glass cutter is used for quick and smooth cutting of glass.
Glass Cutter Types
First you need to correctly determine which glass cutter is suitable for your purposes. Diamond tools are the most trusted. There are two types of diamond heads: tetrahedral and beveled.
The first is suitable for experienced craftsmen. Its cutter is located at a certain angle to the axis of the glass cutter, which requires dexterity when using. It is wrong to tilt such a tool, and the cut will be defective. Determine whether the tool is right when cutting or not, you can by ear, which again requires experience.
A glass cutter with a natural stone can cut glass whose thickness is 5-10 mm.
The beveled diamond head is more suitable for beginners, as it is located on one straight line with the axis of the tool itself, which greatly simplifies its use.
In addition, diamond heads are divided into natural and synthetic. Natural stone can cut glass with a thickness of 5 to 10 mm. Synthetic is used only when cutting material with a thickness of no more than 5 mm. Their wear resistance also varies considerably. So, the natural stone is designed for 10 km of "run", and artificial for much smaller metric area.
The most common tool for home use is a roller glass cutter. It costs less than diamond, but at the same time perfectly satisfies household needs and is much easier to operate. Too thick glass they can not be cut, but, since in everyday life thick glass is rarely used, this glass cutter is quite suitable for home use. It is designed for 350 meters of the girder, further sharpening or changing the roller is required. Modern glass cutters are sold immediately with the "shift", which solves the problem with the lifetime.
Oil glass cutter can cut glass up to 20 mm thick.
Another type of glass cutters - oil. These are the same roller tools, but slightly improved. In the handle is a container with a liquid for lubrication, which is in the process of cutting is fed to the glass. As a result, the friction force decreases, and the cut is obtained much better. In addition, this tool is able to cope with a sufficiently thick glass - up to 20 mm.
It is worth considering that when cutting glass with a thickness of up to 10 mm, you should use a cutter with an angle of sharpening of 135 °. If the thickness is from 10 to 20 mm, then use a cutter with a sharpening angle of 150 °.
There are circular glass cutters. They are a sucker and a bar with a scale, at the end of which there is an oil glass cutter. Using this device is simple. The suction cup is fixed in the center of the future circle, then the necessary radius is set on the rod, then the cutting element goes further. This design allows not only to cut the right circle, but also to easily remove the cut piece of glass.Back to table of contents
Glass cutting technology
Before cutting the glass must be prepared. It should be washed and wiped dry. After all, any debris in the way of the glass cutter can lead to both marriage and damage to the tool. Remember that this garbage may well be imperceptible and constitute a glass crumb or fragments. Dust is also not the best way to affect the quality of the cut.
Glass cutting should be done on a flat surface.
The surface on which the work will be performed must be flat. In addition to a glass cutter, you should stock up on a marker and a thick ruler (at least 8 mm). Marker mark the line cut.
Diamond cutter cut without much effort, pressing no more than a pencil. The direction of the cutting element and its angle of inclination can be determined by training on the draft material. When a thin, colorless trail is laid, note the position of the glass cutter and proceed to cutting it cleanly. Move the tool evenly along the ruler, without changing pressure and tilt.
The roller glass cutter should be held perpendicular to the glass plane. Near the edges they make small lines with a glass cutter, which will make it possible to ease the pressure in these places. Otherwise, spalling may occur. Then, departing with a ruler from the markup on the width of the glass cutter, produce a cut. Starting from the far edge of the glass cutter lead to themselves, tightly resting his side in a ruler.
It is necessary to cut quickly, spending no more than 2 seconds per 1 m.
The pressure should be stronger than when working with a diamond tool, but it also does not change along the entire line, except for the edges.
Whether the instrument is used correctly is determined by ear. A steady hiss or crackle indicates that you are doing everything right, if you hear a squeak or creak, something has gone wrong. Either your instrument is blunt, or you push it too weakly. Small white fragments on the line show that you overdo it with pressure, loosen it.
High-quality cut will make it easy to break the glass and get a smooth edge. Defective line or too thick glass will need to knock on the back side. Move the glass to the edge of the working surface so that the cutting line is 5 mm from its edge. Head the glass cutter, knock along the line from one end to the other. When hit on the glass will crack. Repeat strikes slightly in front of her. The second hand will certainly need to hold the hanging side of the material being cut. It is easy to break off a small strip of glass with the side of a glass cutter or with pliers.Back to table of contents
- Diamond glass cutter lead without pressure along the ruler. Roller glass cutter requires pressure.
- It is necessary to measure the force of pressure, with too much pressure, an excessively deep groove is formed, the edges of which crush and split.
- For 3-5 mm to the edge, the pressure should be reduced, which will avoid rejecting and protect the tool from damage.
- You can not hold a glass cutter twice in one line.
- The roller or glass is greased with a sponge soaked in diesel oil, oil or paraffin. This is done before cutting.
- The rift must be made immediately after cutting.
- The cut strip should not be less than the thickness of the glass itself. For example, if the glass thickness is 5 mm, then cutting off 4 mm from the edge would be very problematic.
- Usually thin glass (less than 5 mm) does not require knocking.
- Instead of tapping, you can warm the cutting line with a blowtorch.
- Glass can be broken by placing a ruler 5 mm or more thick under the edge.
Despite the fact that using a glass cutter is quite simple, people with no experience are recommended to practice on unnecessary pieces of glass. This will allow you to choose the correct angle of inclination, the force of pressure, as well as see possible errors and avoid them in the future. Since glass dust and the smallest fragments are formed when cutting, take care of your safety: do not forget to wear gloves and goggles.
