Diamond overfilm: species, destination. Diamond Filtering Sets

Diamond overfilm is an important tool for any master. By means of it you can even perform jewelry work. A huge selection of different shapes and sizes makes it possible to get to the most difficult parts of the object and give the corners and the surface a proper appearance. But even such a simple tool has its own peculiarities. They will be discussed in this article.

Is this a file?

Diamond over-file is a small file. The working surface of the device is coated with diamond spraying. This provides not only cutting the material during operation, but also scraping its surface, removing a thin layer located at the top. An ordinary nail file is also one of the types of nail files.

Diamond refers to one of the most expensive natural materials. But for what purpose it is used in the instrument? In reality, to create the device, a stone of artificial origin is taken. Due to its high strength, the diamond-coated over-film can work with glass, ceramics, strong steel and alloys.

A set of diamond tools allows the metalworker to process the profile surface with a complex structure. In fact, the devices perform the same functions as the analogs of steel, but cope with materials of a more solid texture.

What does the above file consist of?

Diamond nadfil includes several constituent elements. The main part of the device is made of strong carbon steel. Tools are made by applying grains of diamond powder to the body of steel by electroplating. Grain index refers to the class A16-A4.

Size, granularity, marking of the product

The name of diamond nail files, as well as their shape and size, are regulated by GOST 151Z-67.

The length of the devices varies and varies from 100 to 200 mm. As a rule, in stores more often there are models, the length of which is 80, 120 and 160 mm. The length of their working surface is 50, 60 and 80 mm, respectively.

The material from which the nafiles are made must be harder than steel. When manufacturing a tool such as a diamond filter, GOST 1435 and 5950 requires the inclusion of carbon steel in the following categories: У12, У12 А, У 13, У 13 А, 13Х. The hardness should be at least 55-58 units on the HRC scale.

Another important indicator is the granularity. It lies in the size of diamond grains. Grain is indicated by colored strips or small scratches. Such designations can be seen on the handle of the device. They are not washed away.

To decipher the granularity is easy:

• One red band or two small risks indicate that the figure is 160 / 125-100 / 80.
• The presence of one blue strip or one of the risks occurs at a rate of 80 / 63-63 / 55.
• Models with the smallest grain size do not have any distinguishing marks. This category includes instruments with an index of 50 / 40-40 / 28.

What forms do the files have?

The diamond superfile is represented by 12 species.

1. Tools with three faces. They have a sharp or blunt end. This indicator determines the scope of use of the device.
2. Devices made in the form of a diamond. They make it possible to play with notches at a certain angle.
3. Devices in the form of a wedge are used when working with castes and valves (jewelry elements), as well as with angles with small indicators. Wedge-shaped devices have both sharp and rounded edges, but the nose of the device is sharp.
4. The diamond flat flat blade has versatility. The area of use depends on the size of the device.
5. The slotted devices are similar to flat ones, but the edges are rounded on each side. This makes it possible to process hard-to-reach areas.
6. Square devices are designed for work with grooves of a similar shape.
7. With a semicircular shape. With the help of them, work with reliefs is possible.
8. The naves with different convexities are subjected to processing the inner part of the ring.
9. Oval devices are designed for holes.
10. The diamond round nail file is able to work with rounded products. In addition, with the help of them, the required relief is created.
11. Needle shape is radically different from all other types. First, it should be noted that these devices are miniaturized. The length of the working surface is 35-55 mm. Secondly, the tail of them has a square shape.
12. Another special kind is the superfil-rifel. It should be discussed separately.

Devices with a blunt nose along the entire length have the same cross-sectional dimension. In sharp-nosed models the cross-section of the rod decreases to the edge of the device.

The notch itself is also performed in accordance with the standards. The main working parts of the instrument are marked with a double notch: the main and auxiliary character. Tools with a round or oval shape can have a single or a single spiral scoring.

What is a superfilter?

Riefel is a type of nadfile. As a rule, this tool is used by jewelers when working with thin products and precious stones. The peculiarity of the device lies in its unusual shape, which will not allow confusing this device with others.

In addition, the ripple surface is short. This makes it possible to work with small details.

What determines the instrument number?

The number of notches per 10 mm of the length of the product is the determining number of the product. Manufacturers always indicate the tool number from 0 to 8. It is important to know: the larger the number, the more incisions the implement has, which means that the teeth themselves are small, and the surface will be smoother when processed.

The index of the length of the working surface of the nadfile is always half that of its total length. As already mentioned, it can be of three sizes: 50, 60 and 80 mm. Here it should be noted a very important point - the number of notches depends on the type of size:

• Devices, the length of the working part of which is 50 mm, can have notches from 1 to 8;
• Tools with an index of 60 mm can have notches from 1 to 7;
• Tools having a length of 80 mm are provided with notches from 0 to 6.

Why this rule is chosen is difficult to say. Diamond nadfili are produced according to a certain GOST, and we need only to figure out which set of devices exists in size.

For which jobs are the tools used, depending on the size of the teeth?

A tool with large teeth is needed to work with large surfaces or where a large layer of metal is required to be removed. For example, this work can be done with a file with three faces with a large notch.

The medium-sized notch is more suitable for working with metals that are soft: brass, aluminum, bronze. Such nadfili perfectly cope with the smoothing of the couplings of water pipes for their optimal docking or they remove the jags, and do not "lick" the product.

The smallest teeth are designed for filigree works. Tools are able to increase the groove for the wedge on the shaft of the electric motor. Can clean the burned contacts of current collectors used in everyday life (sockets, protective devices, etc.).

There is a special notch that is located along the body of the device, and not transversely, as is customary. The cross-section of the web is circular in shape. Such a diamond blade for knife sharpening is used at home. It has its own name - musat. Sharpening proceeds more accurately, and also much faster, than emery.

In the market you can see and nadfili unusual shape, which are extremely rare. They have a curved shape. Tools are used to process internal curved grooves. As a rule, a notch in such instruments is present at both ends of the tool, and the handle is located in the middle.

Overview of tool manufacturers

Firms manufacturing this device, there are many on the market. It should be noted such domestic manufacturers as JSC "Metalist", "Zubr". Products of Russian companies have gained wide popularity due to the acceptable cost and high level of functionality. They are in great demand.

Also presented are foreign models: Vallorbe, Bahco, Jonnesway, Matrix, Stanley, Stayer, Sturm. Foreign analogues are relatively more expensive. Masters note that the set of diamond diamond nuts Matrix, Stayer, Sturm has a minus. The tools of these brands are not resistant.

Kit Contents

A set of diamond nail files, as a rule, includes 6-10 devices. A set of 6 devices contains only the basic forms of the canvas. As a rule, it is designed not for professional, but for domestic use.

In any case, when buying a set, you should clarify all the nuances. Indicators of the length and type of incision are printed on the package. In expensive copies, which are sold individually, these data are carved on the profile web.

What should I look for?

When buying a flat or shaped over-file, you should pay attention to the notch on the device. It should not contain any defects. Also, there should be no trace of corrosion, oil. The color of the new canvas differs uniformity, has no divorce.

When buying a tool, check its surface for the absence of growths of diamond powder, as well as detachment.

How to evaluate the quality of the tool?

To assess the level of quality of the device, you need to take two devices and gently pressing them, to hold the working part of one cloth differently. A high-level notch will not bend and not be erased. In this case, the color of the cloth during testing will not change. Strongly applied diamond dust will not fade or turn into crumb.

Handle nadfilya provides convenience of work

The handle can be made of wood, plastic or plastic with rubber coating. If it is not, then the part should be made by yourself.

The best option will be grinding and grinding the handle from the tree. Replace the plastic handle with the base of the toothbrush with a drilled and centered hole from the inside.

The main criterion of the tool should be economy and convenience. Then you can work with it for a long time.

What should I store tools?

Usually sets of diamond-coated nail files are sold in a convenient plastic package or in a soft casing. There they should be stored. In the absence of such a package it is recommended to buy it or store it in a suitable one.

Remember: you can not put tools in a heap, because there is a risk that they will rub against each other, and will soon be dulled.
