Everyone, who was made to hide a tree manually, will surely agree that this is a single and slow process. But even with modest volumes of summer country work, it is worth speeding up, armed with an electric grinding machine.
Grinding tools are often used when repairing old frames
Working with a nozzle in a limited space; The nozzle is deployed under the desired angle and is fixed by the clamp
The rechargeable tool will make it possible to work with comfort not only in the workshop, but also in the garden
Choosing grinding, evaluate the convenience of handle and housing design. In this model, for example, the handle is quite compact, and keep the typewriter with two hands may be inconvenient
Vibrating grinders are especially convenient to use for the processing of flat wooden surfaces of a large area.
In the configuration of the FOX 6-IN-1 multifunctional machine (SKIL) includes three replaceable nozzles for processing various hard-to-reach zones.
Grinding machines are a very extensive family that includes about a dozen devices of different types. Of these, vibration and delta-glasses, we will tell the greatest spread to everyday life, which we will talk about in this article (the corner-glasses are even more common, which are mainly used not for grinding, so they will be discussed another time).
Vibrating grinding machines are arranged as follows. The working mechanism in them serves as a flat platform for rectangular or triangular (in deltashlyphic) forms, which makes reciprocating vibration oscillations with a frequency of about several thousand per minute and amplitude (platform stroke) in 2-3 mm. On its sole, a replaceable abrasive skin is attached.
Grinding takes a lot of time. You may have to keep the typewriter on weight for several tens of minutes, so do not seek to buy too powerful and heavy model
Vibrating grinders can be used almost everywhere where the abrasive skin is used. The most popular options are the blacks or finishing of wooden parts, removal of the residues of old paintwork or rust, grinding the walls after the putty. When working, the master carefully leads the grinder on the treated surface. Even using the power tool, grinding can occupy a long time, from several to tens of minutes. Apparently, therefore grinding equipment is one of the types of power tools in which the mains from the network is mostly used. Minority rechargeable models, and they all belong to the deltashlyphic.
Features of deltashlyphoval machinery
Devices have a work platform of a pointed triangular shape, reminiscent of the weekend of the iron. It is these spout, the master can grind the material in the corners, narrow grooves and other hard-to-reach places where the usual grinder will not get. Of course, there are also open flat sections with a deltashly informal machine, but here it is a little inferior in performance with vibrating-blind models with a rectangular platform (the first working platform is smaller in size). Nevertheless, it can well be considered a universal tool. The preferential sector of the use of deltashlyphic machines - repair and restoration work, and vibration-blinding - construction.How to choose a grinding machine?
How to choose a grinding machine? The optimal option is not only to inspect the tool, but also try it in business. The case must be well lying in the hand (if you are going to engage in grinding, then, most likely, work will be a lot, and the tool will have to hold a long time). Some models when working can be held with one hand, but they should be recommended only to experienced masters. Beginner is better to choose a grinder with handles for both hands.
In cheap models, the handles are often made of "naked" plastic, in more expensive - from soft grades of plastic, similar to rubber, ribbed to the touch. They are non-slip, which is convenient. Pay attention to the power cord. In the grinders, this is a traditionally weak place - with the movements of the tool backwards, current conductors in the cable can be broken. Usually, the veins are broken at the scene of the cable from the grinding, therefore it is desirable that a protective rubber pad is provided on it.
Battery grinders are not very common, however, with the advent of capacious batteries, the situation must change.
It is also necessary to carefully inspect the sole and find out the method of fastening the grinding skirt. A special coating of the sole ("Velcro") is used, acting similarly to shoe clasp, or a system of metal clamps. Velcro is more convenient, but over time, its adhesive properties decrease. With intensive work, it may have to be necessary to regularly change the sole, so professionals prefer more reliable clamps, and we advise you to take an example with them. It is best that both methods are provided in the model.
Pay attention to the configuration of the ventilation holes on the sole and ask how the skins are suitable for your tool, whether they are always on sale. Each manufacturer has a hole in different ways on the sole, so it is often on sale there is no skirts you need, and you have to buy universal without holes, and then for a long time to "compost."
How to pick up the grain of the skins?
To work with grinders, a skin is needed - a grinding sheet on a paper or tissue base with a grain corundum coating. The skin grain is selected depending on the nature of the work - than grain is larger, the rougher is the processing of the material. To refer to the size of the green skins, digital indexes are used from 12 (the largest grain) to 4000 (the smallest).Skirts with indexes 24, 40, 60 are used to remove paint, rust, for coarse primary wood processing and metal. Skirts with indexes 80, 100, 120 are used for the main grinding. Skirts with indexes 180, 240, 320, 400 are suitable for the finishing, thin grinding of solid wood and metal parts. Well, skins with the smallest grains are suitable for polishing.
Grinding works must be performed in several stages using an eye with smaller grain for each next sunset. Therefore, have a lot of slopes of different grain (usually from 80 to 220). Schlifmashin should be moved in the longitudinal direction of wood texture, and not across the fibers.

Important parameters
Battery. Working with a wireless tool is definitely more convenient, but so far such models (for example, the Bosch PSM multishlyl machine 10,8 Li) are just beginning to appear on sale.The area of the working surface (the required sizes of the skins are usually indicated). For domestic use, models with an eyeline of 90-115 mm wide and a length of 140-280 mm are offered. The more, the higher the performance, but, accordingly, the mass increases (on average from 1 to 3 kg)
and power (from 150 to 500-600 W).
The length of the platform and oscillation frequency. Stroke length (from 1 to 3 mm) and frequency (from 5 to 20 thousand oscillations) affect performance. In addition, the quality of surface treatment depends on the frequency of oscillations (the higher the better the quality may be, but some low-melting materials need to be treated at low speeds). Electronic speed adjustment will be a useful option for masters performing different types of work, but it is far from all models.
An additional triangular nozzle turns the vibration tool into a complete analogue of the deltashlifmatch. The nozzle is suitable for processing hard-to-reach corners, grooves, cracks.
Replaceable platforms with a complicated form. Provided in the Duplex model (Festool). This is a professional technique designed for those who seriously engaged in construction. With it, it is grinding profiles, handled the handrails of the railings or flaintly grind - everything that was previously considered to be time-working hand-work.
What to pay attention to when choosing a grinding machine?
Choosing models, pay attention to the cable length. What it is more, the more convenient will work. First of all, we are talking about grinding machines that are designed for repair work on the house. After all, it is no coincidence, let's say, at home models, the cable length is 2-2.5 m, and professional, such as Metabo, - 4 m.

The dust is removed using the air pump, the impeller of which is located on the motor shaft machine. Dustks are absorbed through holes on the working surface, so it is important that these holes coincide with holes on the grinding skin, otherwise the dust will not be deleted. Next with air flow Dust moves to a dust collector
The dusting system must be effective
Dust formed when working is a serious problem, especially when you have to work in the room. Therefore, pay attention to the design of the dust collector. In most cases, it is a rag bag, less often - plastic container. The latter is much more convenient in operation, especially if it has to shake it often. But with a large amount of work, we recommend using a tool with the connection option to the vacuum cleaner. The suction abilities of the vacuum cleaner allow us to act a tandem from a grinding machine and a vacuum cleaner much more efficiently. The only disadvantage of this method is that the shlifmashin is added to the noise of the vacuum cleaner, in this situation it is worth putting protective headphones.The pressure control function informs about excessive nagging to the tool (available in the model 7366 of SKIL). If you put too much, you can spoil the technique. Do not interfere with the tool to do your job!
When working with grinding machinery, small dust is very often formed, so it is recommended to use safety glasses
Multishlifmashinka. A number of manufacturers (Bosch, Skil) produce multifunctional devices "3 in 1", which perform the functions of the delta and vibrationrifmashinok, as well as the eccentric grinders. They are comfortable, especially for those masters who have to periodically perform a variety of work.
