Often in everyday life there is a need to process glass. Basically, this is cutting with subsequent processing of edges. An oil glass cutter will help solve this problem.

Device and principle of operation

All types of liquid glass cutters look similar to conventional tools, but differ in design. This tool includes an oil capsule where liquid is poured . It also serves as a handle. Underneath is a one-piece block with an oil flow control mechanism and a composite cutting roller. The head is made in the form of a solid block with channels for the passage of lubricant.

The principle of this tool is very simple . From a flask located in the handle, the lubricating fluid is delivered by gravity through the channels to the work roll, thereby reducing friction and increasing productivity.

By constantly maintaining the lubrication level, the unit is capable of processing up to 5000 m of glass, while a conventional glass cutter has a capacity of about 300 m.

Thanks to their high productivity and very precise surface treatment, lubricated tools are used on an industrial scale, and the availability of maintenance and operation allows them to be used in the home.

Popular models

The range of oil glass cutters is very large. Even more popular brands that produce this tool:

Fit (Canada) presents his model of a cutting attachment. This device has one monolithic roller, therefore it is resistant to cutting material up to 8 mm in size. The comfortable handle is made of a composite material in the form of a flask, filled with grease using a measuring container. The cutting angle of the roller ranges from 110 to 135 degrees.

The glass cutter is very practical, excellent for many operations, maintains its working condition for a long time, the monolithic roller holds the sharpening well and ensures a uniform cut. The comfortable handle follows the contours of your hand exactly. This advanced design sets it apart from other models. At the same time, the cost is very low, especially considering that the appliance used in everyday life has a service life of more than a year.

Model Stayer 8000M 3369 (Germany) . A fairly good option is a liquid glass cutter with carbide rollers. Suitable for cutting glass from 3 to 8 mm in size. A spring-loaded tip and the use of a grease poured into the pen flask makes the work process less difficult and ensures the highest quality processing. The handle is made of plastic, which is a disadvantage for some users, as it is not the most durable material. However, this design has its advantages: the material is transparent and allows you to immediately determine the oil filling requirements.

This model is characterized by high wear resistance of the working rollers - up to 8000 m. If the tool is purchased for use in everyday life, you will not need to replace it for a long time. The kit includes a practical dispenser for filling the instrument with grease. Most glaziers agree that the device is ergonomic and practical to use. The only negative caveat is the fragile plastic handle.

Chinese brand "Zubr Expert 33684 ". The single roll liquid glass cutter is suitable for cutting glass up to 10 mm in size. The device "promises" a service life of up to 10,000 m. The handle is designed in the form of a flask for storing oil and has a metal body. The presence of a spring in the tip makes it easier to cut glass. A special dispenser is included in the delivery set of the device - with its help you can easily fill in any amount of oil required for operation.

The hard alloy (tungsten carbide) of which the roller is made ensures a long service life, makes it easier to cut even thick glass and a uniform cut. All this, combined with an affordable price, makes the model an excellent option for general home use.

The most popular model is Matrix 887264 (China) . This glass cutter is a professional tool, but it is suitable for home use due to its low cost. The cutting wheel is made of a very tough alloy for increased reliability. The anti-knock handle is empty and filled with spindle oil or other grease inside to improve quality and ease operation. This design of the device increases its service life.

In order for a glass cutter to cut glass at any angle, a special head shape is required. This tool uses a form that expands the range of use of this unit. Chinese manufacturers have managed to achieve the maximum balance of price and quality when developing this glass cutter.

Nuances of choice

The main criteria for choosing any cutting tool are productivity and operational reliability. The oil glass cutter is no exception. To find a good tool, you need to pay attention to two aspects:

• what the working roller is made of;
• a method of attaching the roller to the tip.

The harder the composite of which the roller is made, the longer the service life of the device. The distance between the roller and the oil channel should be minimal or absent. Then the cut will be uniform and of high quality.

Sharpening the knives used in a liquid tool is almost impossible, since they are housed in a holder hidden in a sturdy head . If the shaft becomes useless, the entire unit will need to be replaced or a completely new tool purchased.

Choose cemented carbide models to keep your tool running for as long as possible. Glass alloys quickly become useless.

For high-quality glass processing, it is necessary to select a tool according to technological operations . The sharpening angle should be selected in accordance with the size of the glass to be processed. The range of application of oil glass cutters for glass processing is from 2 mm to 20 mm. When working with thin glass, choose a tool with a cutting angle of about 135 degrees. Such a glass cutter is also suitable for working at home.

Professionals who work on thicker glass prefer glass cutters with an extended sharpening angle of up to 150 degrees.

You shouldn't make a choice based only on the brand name. Domestic manufacturers such as Enkor and Zubr produce quality tools . Quite good glass cutters are offered by foreign companies Krafttool and Stayer. But here you need to beware of cheap fakes. Like any quality appliance, a good glass cutter is expensive. Therefore, when choosing a tool, it is necessary to proceed from the technological process, based on the data in the operation manual.

What oil to fill

Lubrication plays an important role in the function of the tool. The correct viscosity and mineral composition will reduce friction and extend blade life tenfold. Besides, a wet roller winds the glass powder over itself, providing a more even movement of the tool over the working surface.

Most manufacturers of glass cutters recommend the use of specialized lubricants to increase the life of the instrument. The best brands are:

Bohle

Acecut 5503

Milli M2000

Novacan Cutter Oil

T-3133

The compositions of these liquids have a number of distinctive characteristics:

• easily washed off the surface with water;
• optimal viscosity does not allow spreading over the surface;
• evaporate slowly.

The cost of these lubricating fluids is relatively high, so they are often used in professional glass processing, where the quality of the product comes first.

The oils are selected according to the thickness of the glass and the material from which it is made.

To process glass at home, use liquid paraffin and turpentine . The main requirement for them is the availability of a suitable viscosity, which allows it to flow through the lubrication channel. Numerous ethers (white spirit, turpentine) are widely used in liquid glass cutters. It is forbidden to use vegetable and motor oils for glass processing due to the high viscosity of these fluids.

How to use it correctly

The first thing to prepare before processing the glass is the surface itself. The glass must be clean and dry. Foreign inclusions, dust, small particles negatively affect the quality of processing. The cut may be uneven or the glass may break.

To eliminate these shortcomings, it is necessary to wipe the surface with a rag or old newspaper.

After preparing the work surface and workpiece, you can take the tool. In fact, you don't need a lot of instructions to use a liquid glass knife. To cut glass, you just need to know a few simple rules:

• Fill the tool with grease not completely, but 2/3 of the total volume.
• Place the cutting wheel of the tool on the glass surface before refueling.
• When refueling the cutter, use a special flask or pipette. This will make refueling quick and convenient.
• Before the actual processing of the glass, apply with a glass cutter a 5 mm risk on top of the intended cut.
• Cutting glass is done quickly, from top to bottom, with little effort.
• To separate the glass, place a small object under the sheet along the cut line. Align the scribbled line with the edge of the table and press lightly on the opposite side.
• If the first attempt to break off the glass is unsuccessful, it is necessary to lift one end of it and gently hit with a glass cutter from the bottom of the canvas.

Newcomers to glass processing are advised to first practice with useless pieces of material and then start cutting good glass.
