Cutting glass requires not only certain knowledge and skills, but also a special tool. One of the most versatile devices that will suit both professionals and beginners in glass processing is an oil glass cutter. The main advantage of such a tool is a more affordable price compared to diamond analogues. The user will be required to periodically add oil.

Features of using an oil glass cutter
Types of glass cutters.
Glass is quite hard, but at the same time fragile and very capricious material. Working with it requires almost jewelry accuracy: any mistake can completely spoil the workpiece. If you are just starting to master the skill of cutting glass, then an oil glass cutter is perfect for you. It works like a regular roller glass cutter, it has the function of supplying oil for lubrication. The working element of such a tool is a roller made of an alloy of cobalt and tungsten. You can buy tools with 1, 3 and 6 rollers. After one of them becomes blunt, it will be enough to fasten the next one and continue working. The resource of one roller on average is enough for 300-350 m of the processed material.
Such glass cutters, among other things, are popular for their affordable price. In any case, even the smallest diamond, which is equipped with a diamond glass cutter, will cost much more than oil.
The basis of the design of the oil glass cutter laid the roller mechanism. Only it is supplemented by the function of supplying the lubricant from the reservoir to the cutter.
In the range of modern manufacturers available a large selection of glass cutters that use oil during operation. Tools are equipped with simple and ergonomic handles.
The design of the oil glass cutter is equipped with a special system of oil supply. A grease cartridge and a wick are integrated in its handle. This system allows to significantly reduce the friction of the roller of the glass cutter against the surface of the processed glass workpiece, without compromising the quality of the work and extending the service life of the tool. In addition, the oil allows you to hide small fragments, which provides a smoother movement of the cutter. Most models are suitable for working with glass no more than 20 mm thick.
Billets of different thickness require the use of rollers with different sharpening. For example, work with glass with a thickness of 1 cm is carried out using a chisel, sharpened under 135 degrees. If the glass is thicker, it will be necessary to install a roller with a sharpening under 150 degrees on the glass cutter.
The most convenient in the work of oil glass cutters with a rotating roller. It allows you to process workpieces with an uneven surface. Periodically, an oil glass cutter will need to be updated, replacing worn mounting mounts, rollers and side parts. Spare parts for the glass cutter from a more or less well-known manufacturer can be bought without any problems.Back to table of contents
Features of the choice of oil for a glass cutter
Glass cutters of this type are equipped with a tank for oil. The oil supply made the design of the tool a little more complicated, because, for example, diamond analogues did not need to use lubricants. However, modern glass-cutters, which use oil in the process of operation, noticeably outrun diamond analogues both in terms of resource and cut quality. You just need to know how to choose a quality oil.
Modern glass-cutting machines, which use oil in the process of operation, noticeably outperform diamond analogues in quality and convenience.
To choose a good lubricant, carefully study it before purchasing. Quality oil must meet the following requirements:
- Have a consistency to easily penetrate the lubrication channel.
- Have suitable adhesion, do not run off the roller and its axis, do not spread over the workpiece.
The basic requirements of only 2, but not all the oil meets them. Incorrectly selected viscosity will lead to the fact that soon the head of the glass cutter will be lost. Therefore, it is better not to save, especially since saving too much will not succeed anyway. Even a small package of 200 grams is enough for a long time.
You can check the quality of the oil immediately with a glass cutter. To do this, pour the lubricant into the appropriate reservoir, and then lightly press the tool head against the glass so that the lubricant passes to the roller. High-quality oil will flow through the roller on the workpiece and leave behind a very small round spot.Back to table of contents
Preparing the desktop and glass for cutting
Glass is quite easy to process, you just need to follow a number of simple rules. If you have never had to use an oil glass cutter before, start your workout with a work surface preparation. The surface must be such that during operation no vibrations are created. In addition, there should not be any irregularities on it.
For glass cutting it is necessary to have a glass cutter and a ruler. Work should be in protective glasses.
A simple desktop does not always meet these requirements: it was probably repeatedly knocked on it, it was exposed to moisture, etc. Therefore, it is better to immediately prepare an ordinary fiberboard. It is worth a penny. Put it on the table and all the bumps will disappear.
To work you need a minimum of tools:
- Glass cutter
- Safety gloves and goggles.
Before you start working with an oil glass cutter, you need to properly prepare the glass. New glass is sufficiently thoroughly cleaned from dirt and dust using a rag. Old billets, as a rule, have to be washed, because Existing stains are usually not cleanable with a single piece of cloth. You can wipe the glass with an ordinary newspaper - this is the most simple, affordable and effective way.
After washing the surface is recommended to degrease. This can be done with ordinary turpentine or alcohol. After that, the glass should be left until it dries.
Glass cutting technology.
During the work, you will need an auxiliary ruler. In addition, experienced craftsmen use another effective technique: they draw a work surface on which the glass will lie. The material is transparent, and during work you can see exactly where you need to cut it. Spend and you such a fat line. Then take a glass cutter and make marks on the glass. Apply 2 small lines at the start and end of the cut line.
After that, place the blank on the glass so that the marks put are parallel to the line that you previously applied to the table. Between them there should be a distance of 2-4 mm. Press the ruler firmly against the glass surface. Be sure to make sure that it does not fidget, and only then begin to cut.Back to table of contents
Guide and helpful tips on working with an oil glass cutter
If you are a beginner, practice your work on unnecessary fragments of glass before starting work. Consider the fact that the cut line must be made in 1 attempt. Repeated approaches in most cases lead to material damage.
It is very easy to work with an oil glass cutter - you just need to take it at the base of the handle and, with little effort, draw the right line under the ruler. When driving, a crackling sound will be heard.
It is very easy to work with an oil glass cutter - you just need to take it at the base of the handle to smoothly draw the desired line under the ruler.
Control the pressure. The cutter should not be pressed very hard, but surely. Approximately 0.5 cm to the edge of the glass, relieve pressure, otherwise the cutting part of the tool may be damaged.
As a result, you should get a pretty deep whitish line. You do not need to push too hard on the glass cutter, this can lead to the fact that the edges of the workpiece will crumble. You can not lead more than 1 time under the same line: that you dull the glass cutter.
For most beginners, the most difficult stage of work is a fragment of the cut part from the main workpiece.
The rule is simple: break in the opposite direction to the scratch. If the glass does not give in immediately, in no case do not cut again.
It is only necessary to tap the tool handle on the opposite side of the workpiece, from the edge of the sheet. Noticing a crack on the glass, you need to "bring" it by tapping to the other edge.
At the same time support the workpiece, because during tapping it can break off by itself. Over time, you will learn to make such lines, with which the glass will break on its own, and you will not have to make additional efforts. Try to minimize the number of fragments. Do not throw away the remaining pieces of glass: having mastered the techniques of cutting glass, you will surely find use for them.Back to table of contents
Features of working with different types of glass
When cutting simple glass, there are no difficulties, as a rule. Oil glass cutter cuts it without any problems. However, if you have to cut glass with a more complex configuration, you need to know and take into account a number of features, without which it will not be possible to perform work in high quality.
Tempered glass can not be cut at home.
First you need to familiarize yourself with the properties of tempered glass. Cutting such products at home is not recommended. Provide all the necessary conditions you are unlikely to succeed, and the workpiece will simply lose its properties. If you are planning to buy an item with elements of tempered glass, think about how it will be cut, even at the initial stages. It is not recommended to process such products before you learn to work with all other types of glass.
Another type of material that often comes across is corrugated glass. It is a patterned material and is used, as a rule, in the glazing of doors and the creation of various decorative elements of the interior. With sharp such glass is quite possible to cope on their own. The process of its processing differs from working with ordinary glass only in that the incision needs to be made from the smooth side. And the oil glass cutter copes with this task perfectly.
Organic, it is acrylic, glass is a transparent plastic, in the production of which synthetic resins are used. It can also be cut without any problems with an oil glass cutter, and if it is not available, you can do with improvised tools such as a cutter, saw for metal, etc. In addition, even an ordinary stationery knife is excellent with thin acrylic glasses with a thickness of up to 2 mm.
Regardless of what kind of glass you will cut, do not forget about the observance of simple, but very important safety requirements. First, you can work exclusively in protective glasses and thick gloves - this is the main condition. Secondly, you need to properly arrange your workplace. In the process of cutting glass, fragments will inevitably form. Therefore, it is recommended to cover the work surface with such material that it will not be a pity to get rid of later. All this will allow you not to worry about your own safety and concentrate as much on your work as possible. Practice, follow the instructions - and you will succeed. Have a good job!
