Rechargeable Bulgarian: the necessary information about the instrument

Angle grinders (LBM) have become an indispensable device truly. The first copies of compact products in the former Soviet Union were made in Bulgaria. That is why at the present time are increasingly found the name "Bulgarian". Next will be considered the basic properties and features, which characterize the battery bolgarka.

Bulgarian "Makita": Answers to the most frequently asked questions

Domestic consumers have long loved cars, presented by Makita. This manufacturer has long been included in the first ranks of the world leaders in the manufacture of tools for the construction. Top quality, excellent performance parameters, strict observance of the guarantees - all these advantages, the Japanese company has won over a century of its activity.

Makita angle grinders are quite multifunctional device. Talking about what is needed of the Bulgarian firms, it is worth noting that it allows you to cut and to carry out polishing tiles, brick walls, concrete blocks, metal products and other solid materials. Makita LBM can be used in the process of work connected with the dismantling and during cleaning of different surfaces.

It is interesting! Many artists are wondering about how to properly called Bulgarian. So, the correct name of the instrument - angle grinder, or abbreviated as LBM.

Regardless of the model, each battery bolgarka "Makita" has the following advantages:

• significant power headroom;
• effective starting current limiter;

• the ability to set the desired number of turns;
• replaceable nozzle without the use of a key;
• presence option fine adjustment speed.

In addition, the Japanese experts managed to develop a set of original innovations. In order to maximize battery protection LBM "Makita" is equipped with a special dust bag. And thanks to the perfectly compatible adapters can even perform a connection to a vacuum cleaner.

As for the drawbacks, in the firm of their devices were found. In order to understand what kind of machine to give preference, should carefully review the different models of the storage grinders (User feedback will help make the right choice).

Bulgarian on the battery:the main secret of

Among the most important features of LBM on the battery is the possibility of completely autonomous operation. This means that lay the cable from the mains socket is not necessary. In the country, in the woods, on construction sites - use this tool it is possible anywhere.

Note! An important advantage of wireless grinder is high safety during its use. Giving preference given instrument, can completely protect themselves against electric shock, as well as to be able to perform the work with high humidity.

Due to the simple design of grinders on the battery, as this instrument is often the most positive reviews. Despite the fact that each apartment has outlet for hard to reach areas such Bulgarian It characterized by a much greater convenience than a power tool that connects via cord. Charging the battery replacement comes from the socket.

Arguing about what Bulgarian better, we can safely say that the battery. Its main advantage is the portability. This tool is characterized by compact and lightweight. In comparison with the products supplied by the mains, embodiments accumulator during operation emit far less noise.

Another undoubted advantage of the tools with the battery acts as a small power Bulgarians. Electric motors, they are equipped with a work at relatively high speeds. This makes it possible to carry out the work of a small disk with no less effective than when using large elements. The increased speed of rotation gives the accuracy of processed materials, while avoiding the possibility of scratching.

One of the most common issues that arise after purchasing it boils down to how to use the grinder. Given the chance to any of the nearby outlets, you can connect the device to charge, which is equipped with grinder.

Important! In the operation of angle grinders must always be correctly installed special casing, which has a protective function. He is not only reliable protection against sparks and particles of material that is easy to work with, but also protect against fragments, if in the process of bursting disc.

If the machine is equipped with a speed control option, the best solution would be to use the maximum possible for a particular disk. During the cutting pitch is better to carry out extremely smoothly and without undue pressure. In case of skew incision tool is uneven, and the disc may indestructible.

If you need to coarse sanding, if necessary to remove a significant layer of material, it is better to give preference to the stripping disk. The tool thus must be kept under a slight inclination to the surface. It is necessary to check that on the material treated, there was no deep grooves. To carry out stripping in any case can not be used saw blades. They are too thin and break even at the lowest lateral bending.

If, during a long stream of sparks was seen a diamond disc, this indicates that the device is blunted. You can fix this by following a few notches this drive in any of the solid materials. If the sparks form a continuous ring, it means that there was a complete deterioration of the surface, and without changing the disc can not do.

Cordless angle grinders: rating of the best models

To get a rough idea about the types of storage grinders, attention proposed an indicative rating of various cost Bulgarians - from the most expensive to the cheapest options professional.

Note!Despite the significant advantages, LBM Vosch battery is not without drawbacks. Devices that belong to the professional, have a high cost.

Mini Bulgarian: Though small, but very udalenkaya

A key feature of the mini-Bulgarians is the large number of modifications. Because of this, choose a specific model is quite difficult. The main difference between a miniature angle grinders from large grinders acts disk size.

Mini grinder differ in such parameters:

• degree of engine power;
• speed frequency;
• weight;
• size;
• options.

Dimensions are the main difference between small devices on classic cars. Mini size suggest standard Bulgarian complex essential elements. Thanks to the various sanding or cutting disc and complementary parts, only expand the device.

Due to the universality of small machines can be highly precisely perform various tasks. Mini unit is able to cope with the jeweler's work, while the classic instrument they simply can not afford.

Despite the fact that the battery of mini-Bulgarian and tools of conventional size are equipped with similar functions, it is worth noting that the first device is endowed with a lot of positive qualities. For example, a small unit is easier to hold in your hand. The employee will not suffer from physical fatigue while performing lengthy operations.

Mini-guns are not even suggest the presence of a protective rim. However, compliance with the safety rules has not been canceled. Regardless of the dimensions of the device, the technical requirements must be followed.

Note!Some believe the mini-product is very unreliable due to the lack of details, typical of conventional tools. The danger lies in the use of incorrect size circles. They may cause injury in the event of negligence in the course of their choice.

Due to the absence of electric cable work grinder turns into a very easy process. Talking about how to choose grinder, 125 mm (meaning the size of the circle) is an excellent option. However, when choosing the tool size is also important to take into account the processing material. For example, while working with the metal, it is better to give preference to the minimum size of the disks. At the same time the Bulgarian wood can be equipped with larger components.

Rechargeable Bulgarian: A few words on possible malfunctions

Armed with knowledge of the design features of the LBM, it will be easy enough to identify basic faults that may be encountered during the execution of works. For example, a problem with the motor does not always become a cause total failure of the device. Often, it is only limited functionality.

Perhaps the most common nuisance is blown resistor resistance that provokes non-functional power button. By the way, this element is not equipped with all models. However, the problem can be solved easily by replacing the elements which are the cause of the fault. A similar problem may arise due to the ingress of dust under the holder. This can be corrected by cleaning the contacts and replace with a new button, if necessary.

In general, all the faults that can grasp the tool (grinder), are divided into two types:

• electrical nature;
• mechanical plan.

The notion of a mechanical problem meant the wear of bearings. This problem is manifested by increased body vibration, noise and excessive heat.

To eliminate the need to remove a part, to replace them and lubricate with an additional tool. In appearance and easy to identify the failure of the gear teeth. This can be remedied by replacing the gears.

Note! Most mechanical problems can be easily avoided by timely servicing tool. For example, sander requires purification units, as well as lubricants and replacement of damaged elements.

As for troubleshooting electrical nature have tools often fail rotating elements of the motor. If it is not a brushless grinder, you can also run into trouble such as wear of brushes, collector or gear.

Replacement of brushes is required when working within the housing of the device there is excessive sparking. Normally, it is smooth or invisible. Anchor Mini product breaks down due to the heavy load. Typical manifestations of failure are fumes, sparks and heat the body. With regard to the repair of the electrical components, it is better to trust the professionals.

How to choose a grinder for home: Key Secrets

Thinking about what kind of grinders to choose for the house, it should be borne in mind that the correct choice will require the ability to perform analysis and comparison. The main parameter is the index tool rotation speed at idle. This is the power indicator. Thus, powerful models are characterized by higher performance.

Due to the fact that the grinding machines equipped with additional options, the question of what kind of pick grinders, complicated. On the other hand, due to the additional elements of material handling process becomes easier.

For example, the automatic blocking of wheels helps to eliminate irregularities in the process of grinding and cutting provoked vibration, which is caused by worn disks. With inrush current limit mode provides stable operation of the tool during normal performance standard electrical network.

Fixing represented by an optional handle makes the cutting process significantly easier. Without it, the need to have a strong physical pressure. It provides additional convenience and special coating which helps to reduce the vibration force. This makes it possible to carry out high precision materials processing.

Note! The optimum size of the disk is more convenient to perform accurate cuts. For example, for figural operations are applied to the following minimum rates. The more accurate and finer work, the disk size must be smaller.

If we are talking about what to choose grinder for home, should take into account that the best option would be a product with a diameter of 125 mm discs. The size of the element depends on how deep the cut will be. The optimum thickness range is from 1 to 1.2 mm.

When choosing a tool, it is important to remember that the best grinders - devices that are easy to use. Are important objectives that have been set. For example, fans of lightness and compactness will also appreciate cordless products, and without big LBM will not be able to do, if to be cut thick metal profile or viscous materials.
