Why is a grinder called a grinder - the origin of the name of the angle grinder tool for metal, what is the correct name and where it came from

Construction tools and machines are often given unusual names in people's everyday life. Some talk about belonging to some kind of manufacturer, others about the possibilities of devices and equipment. Such designations are so "firmly" included in the vocabulary that many builders find it difficult to say how the instrument is correctly called or why it is so named. From the article you will find out why the Bulgarian is called the Bulgarian and where this name came from.

The history of the origin of the name Bulgarian

In the 70s, our production was focused on the manufacture of industrial tools, and there was a sorely lack of construction equipment for manual work in the country. That is why Elprom Lovetsch Bulgarien started to produce small machines that can was used in everyday life and small workshops for the production of stone, metal and wood products.

With all the positive qualities of a Soviet person, he did not differ in knowledge of foreign languages ​​and could pronounce only one word from the Bulgarian name of the manufacturer - Bulgaria. And since the type of tool is officially called a machine, the builders called it "grinder".

Reference. Elprom Lovetsch Bulgarien has been producing construction tools and equipment to this day and is focused on the manufacture of compact power tools for household use.

What is the official name of the grinder

The construction machine of compact dimensions is called by different names all over the world. And rarely any of ordinary people will answer: why angle grinder is called a grinder. However, the sander is so popular that it is found in almost every home and garage. Professional craftsmen know that any work is impossible without sawing, grinding and cutting materials.

But everyone who works with this tool should know what an angle grinder is. a machine that is produced with different technical characteristics, but its principle of operation remains unchanged.

Why is the tool called an angle grinder

To answer the question why the grinder is called that, you need to know how it works and what tasks the tool can perform. The sander is designed for cutting metal, wood and stone, as well as sanding materials to give them a smooth and aesthetic appearance.

What does a grinder look like, and what main nodes does it consist of:

1. Cylinder-shaped body that houses the collector motor. In different models, it may differ in power and number of revolutions per minute.
2. The handle, which can be stationary and adjustable at different angles for the convenience of work, which determined the correct name of the grinder.
3. The attachment point for grinding brushes and a disc for cutting materials.
4. Start switch and power cord.

Some models are equipped with a speed controller, automatic balancing and protection functions against overheating and accidental activation.

How do the inhabitants of Bulgaria relate to the name of the instrument

In the understanding of the inhabitants of this country, a Bulgarian is a woman born in Bulgaria. The generation that caught the Soviet Union knows the unofficial name of the instrument, and young people are often surprised at the colloquial name. But most people react with curiosity and humor, and many are even pleased that their country is associated with a popular construction tool.

Other names for grinders

In our country, there are several more unusual nicknames for the angle grinder, but in European countries it is usually called "Flex".

The most common names for angle grinders in everyday life:

• “Fortuna” - the first models of the instrument from Bulgaria were called just that;
• "Monkey" - it is difficult to say about the origin of this name, but there was no balancing in the design of the machines earlier and it "walked" in the hands, which was dangerous;
• "Turbinka" - now the instrument is so rarely called, but the association came from the similarity of sound when working with aircraft turbines.

And also this machine is called "cutter", "angle grinder" and "grinder", depending on what kind of work it does.

What is a grinder for?

The popularity of the instrument is due to its versatility. Many people know what a grinder is, but they believe that it can only cut and grind different types of materials. Today, a large number of attachments are provided for angle grinders, which can be used in repair work and in the production of various products.

What is a grinder for and where you can use it:

1. Cutting. At any hardware store you can buy cutting discs that are capable of working with a variety of steels, stone, wood and concrete.
2. Grinding. Abrasive attachments can help remove rust, sand wood planks or clean brick and concrete surfaces from dirt, efflorescence and mortar residues.
3. Polishing. Wheels with a cloth attachment are able to bring the car body or other smooth surface to a "mirror shine".
4. Sharpening. When installed on the abrasive wheel attachment, almost any cutting and piercing tool can be sharpened.

In everyday life and on construction sites, a grinder is most often used for metal, with disc elements they remove scale after welding, grind the seams and clean the structures from rust. And also angle grinders are widely used in car services and woodworking industries.

What is the angle grinder now

Modern models are equipped with a wide range of additional functions that simplify the operation of the tool and make it safer. When choosing angle grinders, you need to know the basic technical characteristics in order to provide a home or production with a reliable and versatile tool.

The parameters possessed by modern models of grinders:

1. Rotation frequency. Directly depends on the diameter of the disc for which the machine is intended. Typical cut-off wheel dimensions are 115-230 mm and rotational speed 6650-13200 rpm. Allowable parameters for angle grinders are indicated on the information plate installed on the grinder body.
2. Engine power. The larger the disc diameter provided for use on the tool, the more powerful the motor is installed on the machine. The technical parameter varies between 0.65-2.7 kilowatts.
3. Protective cover. It can be removable, which expands the possibilities of using the grinder and installing circles of different diameters on it, and stationary, which does not allow the use of larger removable elements.
4. Adjustable handle. Assumes the installation and fixation of the handle in several positions, which simplifies the work with the tool at different angles.

Additional features to look out for

Features of some models will make working with angle grinders safer and more convenient, which will allow you to perform all available operations for the grinder. The cost of a tool with a full set of functions will be more expensive, but they can significantly save the time and effort of the owner.

What the manufacturer additionally equips the grinder with:

1. Start current limitation. At the beginning of the machine's operation, the electronic device gradually increases the speed of the disk, which eliminates shock loading and prolongs the life of the engine and gearbox.
2. Rotation speed stabilization function. The resulting friction when the disc touches the processing material increases the load on the engine, which can quickly damage it. The function eliminates deceleration, which prevents the engine from overheating.
3. Restart protection. The function locks the angle grinder in the event of a sudden power outage, which avoids injury if the motor spontaneously starts when power is supplied. To restore work, you need to remove the plug from the socket and turn on the machine again.
4. Auto-balancing. The function evenly distributes the load from the rotating blade and reduces vibration during operation, which affects the quality of cutting and grinding.
5. Overload protection of nodes. Eliminates overheating of the motor when the temperature or current increases. Special sensors block the operation of the angle grinder.

Additional functions make the tool easier to use and extend tool life. They also make the use of the typewriter safe and convenient.

Conclusion

When the question arises, how does the angle grinder differ from the grinder, you can give an unambiguous answer that this is one and the same tool. But modern models differ significantly from the first hand-held typewriters, which were originally made in Bulgaria.
