What is an electrician for

Most often, an electric jigsaw is used for the manufacture of wood products. This tool found widespread use in furniture production, where elements and details of various shapes are made with its help.

If, when working with an electric jigsaw, choose the right consumer and cutting mode, then you can:

  • make even and curved cuts;
  • cut circles without damage to the sheet;
  • cut thin metal;
  • make wood from wood with a thickness of up to 10 cm (the model of the electrolobian Dnipro-M le-110R cuts bars of 11 cm);
  • cut plastic;
  • saw ceramic and porcelain tiles.

Will the power tool work with this or that material will depend on the power and type of tool (household, semi.professional, professional). Not all electrical jigsaws have additional functions, such as an inclined cut or the ability to connect additional elements and tools. To choose the right tool, read the article “How to choose an electrician“.

In this case, you also need to choose the right saw canvases. The step of the teeth, their length, material are taken into account.

The most common breakdowns, how to avoid them and safety precautions

It is important not only to know how to saw an electrician, but also try to avoid reasons that can lead to a breakdown of the tool.

Electric motor. Most often, the engine fails in electric. There may be several reasons for the breakdown: burning off the rotor, stator, wear on the shaft. To avoid burning of the rotor, you need to purchase a tool, the power of which will be enough to perform the required tasks. For example, if you need to cut the blanks of a large thickness, a jigsaw with a capacity of 400 watts will not be enough. the engine simply will not withstand the load and burn out. It may not lead to this and insufficiently high voltage in the network. It is not recommended to install reduced speeds too often: a lack of cooling and high currents can lead to burning out the winding.

The notch on the shaft can be worn out as a result of constant shock loads on the stem of the tool. Shock loads on the rod appear due to improper selection of equipment. Therefore, always follow the recommendations when selecting a saw canvas.

Power button. Sometimes the owners of the electrician are faced with impaired operation of the power button. Pressing on the “trigger” leads to a circuit closing and starting the engine. If metal dust gets into the case, the normal operation of the power button may be disturbed. To eliminate dust in the process, you can use a special vacuum cleaner (household is not suitable). The “trigger” can lead to failure of the natural wear of conductive paths. I must say, this process is quite long.

Mechanics. Among the mechanical nodes, a rod may turn out to be problematic: this part is subjected to serious mechanical loads that occur during sawing. The mechanism of fixation of the canvas is the weakest in this system, t. to. It is directly related to the rod. Do not be afraid of the breakdowns of the gearbox if the case reliably protects the internal mechanisms of the tool from dust.

Safety and maintenance of an electrician

The basic safety rules are necessarily indicated in the operating manual. It is strictly forbidden to perform any work in a state of intoxication. Before starting work, you should make sure that the tool is working, the presence of protective glasses and gloves, voltage stability in the network. You need to take care of good lighting the workplace in advance. Electric work should be carried out in a dry room. There should not be flammable substances nearby.

At the end of the work, the tool is carefully cleaned of dust, if possible, it is blown out by air (when the engine is running, the effectiveness of the purge will be higher). As necessary, the lubricant is applied to mobile parts. Store the tool in a dry room. Compliance with these simple recommendations will significantly increase the life of an electrician.

How to saw wood-made stove, laminate

Next, we consider how to spill the wood-brown stove with an electrician to avoid damage to the laminated facial surface.

The choice of files. Experts recommend using a reverse cut file. True, in the process of work, a feeling of discomfort may occur due to increased vibration, but the quality of the cut will not suffer. If sawing is performed by a regular file, work is carried out on the back of the processed material.

The frequency of the course. The speed of the course must be set maximum.

The pendulum mechanism. In order not to form chips of the pendulum mechanism, it is necessary to turn off.

The process of sawing. The tool must be tightly pressed to the surface of the material, while it must be carried out smoothly without strong pressure.

Chips appear precisely on the part of the material that is facing the tool. Therefore, if the cut is made with a file with ordinary teeth, then you can in advance the front side of the product to drink on the back side.

In addition, for the implementation of cuts in a wood-based plate or laminate, you can use an anti-ski liner. This is a small part with a cut, which is inserted into special guides on the sole. The most ideal liner is the one in which the sawdown exactly corresponds to the thickness of the saw canvas. Therefore, some manufacturers complete with an electrician supply several such liners. At the same time, I drank in each of them yourself. After which you can start sawing a wood-piece plate.

General information about the tool

The jigsaw is called a saw, the cutting canvas of which makes a reciprocating movement. Depending on the design, the tool performs from 200 to 3000 vibrations every minute, through which the metal blank is cutting.

The jigsaw, unlike most saws (manual, end and others), is intended for figure cutting. over, it is difficult for them to get strictly a straight line for the trimmer of the cut, and the curve is easily. However, there are products for cutting at right angles. They are equipped with special guides and cost a little more analogues, while weighing the structure.

Specialists divide the metal lobe into groups by a number of parameters, including:

In accordance with the last criterion, the tool is divided into two types:

The former allow you to keep the tool in one hand, which is why the cut accuracy is reduced, but the scope of use is expanding. The second must be held with two hands, after fixing the part. This is inconvenient, but the accuracy of cutting the workpiece increases.

The type of handle allows you to classify only manual models. Electric ones are different. Further. in detail about other types of cutting tools.

What to pay attention to before buying

The most important thing is not to buy a professional model, which will be used once a month, or household and try to work with it for 5 hours a day. Therefore, the user should pay attention not only to the power of the jigsaw. Further. a few advice on choosing.

  • Ratio of the thickness of the workpiece and power. Hand household jigsaw cuts metal up to 4 mm thick, professional-up to 10-12 mm. It is desirable that both of them have at least 500 watts.
  • Functional. Think about whether you should overpay for a tool with backlight, blowing system, pendulum passage if the device is used for 1 hour per month? Very possibility is welcomed by professionals; an amateur can do without them.
  • The ability to set up the frequency of file movements. If the cutting canvas can change speed, the tool is good for several metals at once (for example, steel, copper and aluminum). This is due to the fact that thick blanks (5-10 mm) are cut at low speeds, otherwise the file may crack or swipe.
  • The choice of files. It is important to know the type of shank and the method of fastening the file (this is indicated in the technical passport of the product). The cutting canvases are also distinguished by suitability for certain metals, which affects their parameters. a step of teeth, their number, the thickness of the removable element.

A file for a metal jigsaw can be found by a characteristic marking. T118 A (workpiece thickness up to 3 mm), T224 D (for aluminum) and so on.

metal, electrician, useful, equipment

Remember that the tool (amateur. especially) requires rest. After 20-30 minutes of work, it is worth laying the jigsaw to the side to avoid its overheating. With professional models differently. they work for several hours. If you feel that the tool body has heated (due to the continuous operation of the engine), it makes sense to give the device to rest.

In short, this is all you need to know about metal jigsaws. If you have something to add, share your thoughts in the Комментарии и мнения владельцев.

Metal can be cut with different tools, but it is not always convenient to use, for example, an angular grinder or a hacksaw for metal. In some cases, a manual or electric jigsaw with appropriate files is more suitable for business.

To make the cut as accurately as possible, it is important to choose the right sawing canvas for such work.

What canvases uses an electrician

In the traditional performance, the electric jigsaw is equipped only. But actually it is not. A jigsaw with an electric drive is often equipped with an abrasive canvas, as well as a blade.

Abrasive.type canvases work on the principle of a file or file. A blade canvas is the same knife that is convenient to cut rubber, plastic and other materials with a soft structure.

Of course, in the vast majority of cases, an electrician is used to cut materials. To effectively saw, the jigsaw is equipped with a serrated canvas. For electrolobsics, canvases of increased thickness and improved strength are used.

Types of saws for an electrician: what and how to saw

For those who have an electrician in their household, from time to time should purchase files for him. There are quite a lot of varieties and manufacturers. The most common types of saws are of course on wood, except for them there are canvases for metal, tiles. In order not to be especially confused, we will consider the most running saws in everyday life, Bosch company. In the ratio of price/quality. good choice. The letter “T” in the marking indicates the type of shank-T-shaped. The most common type of file.

Wood saws. There are several types, it all depends on the nature of the work ongoing.

Fast sawing files.

For example, if you need to cut a bunch of boards as soon as possible, then a file with a large tooth is best suited. The larger the tooth, the faster the cut, but less neat, the cut is not very smooth, but if you make a fence, or build a barn, then accuracy is not needed in principle. For these purposes, you can take a file with a marking T101D. It is suitable for boards up to 75mm thick. If a board or bar is up to 100mm, you need a file 244D. For boards up to 200mm. Long saw 344D. It can be seen, the larger the figure is in the marking, the more a file is intended for a thicker board. It must be taken into account that for a thick board you will need a good and powerful electrician.

For pure cut, you need a file, for example, T101V.

Her tooth is noticeably smaller, respectively, the cut is smoother. This is suitable for assembling furniture, where you need an accurate and even cut, without chips. Often it is used for sawing wood-fiber slab, plywood, woody stove. She can saw her thick boards of course (up to 75mm), but it will take longer longer than the files with a large tooth.

Laminate saw. Has a reverse tooth, directed in the other direction in comparison with the rest of the files. This is done so that chips from the front side of the laminate does not work out, do not spoil the appearance. Small tooth. for pure cut. It has a marking T101BR.

The letter “r”. denotes a reverse (reverse). And so it is no different from a simple tree T101B.

Figure cut.

Their tooth is always small, used to cut the radius, circles, are used in the production of furniture. In shape, they are already noticeable than everyone else, this is done so that the file does not clamp when turning the jigsaw. From personal experience, I can say that I cut a circle in the plate of a wood.fiber plate for the sink, the cut turned out to be very accurate and even. Marking at such pieces with the letter “o” in the title. T119BO.

They always have a small tooth so that it is easier to recognize them, their shank is blue. If you saw the metal up to 3mm, the T118A saw is suitable, you can also saw plastic for metal up to 6mm. T123X, for aluminum. T227D, its tooth is larger.

Universal saw for metal and wood

You can saw both wood and metal. Her tooth in one half of the canvas is small, on the other large. Marking T345XF.

Peel for ceramic tiles. It has a marking T150RIFF, T130RIFF. On the edge she has a carbide spraying.

Most often, files are clamped in a jigsaw using a 3mm hexagonal key, sometimes there is a quick.packed mechanism.

As for prices: the most running saws cost about 25-40, long for a thick board of about 80 rubles. The saw on ceramics is released from the general row, it is 150-170. are relevant for 2012.
