In the house of each man should always be a different kind of tools that will allow you to quickly and simply repair something in the house. This can include the hammer, nails, hacksaw and much more. One of the items is the angular grinding machine, which in the commoner has long been called the grinder. Its main purpose is grinding and polishing various surfaces and materials. But that these processes are as efficient as possible, you should know how to work with a grinder.
How to cut a tree?
Let’s start with what often happens that there is a need to cut off the boards or trim a piece of wood. For such works there are special disks of one species. Such a disc is a solution with teeth on the sides, increasing the width of propyl. It should be used extremely gently, if it comes to cutting the boards with a thickness of no more than 40 millimeters or to make a descent on a knife. No one should apply discs from the circular, due to the fact that they are designed to work at speeds not more than 3 thousand revolutions.
And the Bulgarian speed is significantly higher. Yes, and wheels from it are usually created, though from hard steel, but it is extremely fragile and usually immediately destroyed when encamping.
How to cut ceramic tiles?
If we talk about cutting ceramic tile or there is a need to cut a porcelain stoneware, this can be done by applying a disc made of steel and having a diamond fine-grained spraying. Another similar option is called dry cutting option. Such discs can be solid and segmented. Home use of such solutions allows cutting ceramic tiles without cooling substances for 1-1.5 minutes. Then the disk should be allowed to cool with idle rotation. If we talk about a solid disk, then he perfectly cuts a ceramic camp for sidewalks.
Work with metal
Metal is a material for which the tool was intended initially. Using a grinder, you can easily cut the rail, rebar, cast iron, various metals. You can also dig a tube smoothly without problems. It should be said that the metal requires maximum attention and caution. In addition, special specials made of rigid type wires will be required to clean the surface from scale or rust. If you have to work with this material, a number of rules should be observed.
- In the paper it is necessary to make pauses every 5-7 minutes cutting. This will especially be important for the domestic tool, which is not suitable for especially hard work. Yes, and the durability of the device and disks will depend highly on this.
- Billets should be fixed as securely as possible using clamps or vice.
- When cutting thick metal cuts, it will be better to cool it. Can do it by dumming cold water.
- If there is a cutting of aluminum, then to reduce friction and the disk is better cooled, you can drop a little kerosene in the cut. But here you should be attentive in terms of fire safety.
The main attention when working with the metal must be given exactly the cutting disk. Need to follow, in order not to be pinned with the edges of the metal. Best will be if a piece that is cut off will be like hanging in the air. We are talking about cases when working with such materials, like a pipe, corner, rounding, fittings, and so on. It will also be superfluous to note that cutting metal products – various rails, the corners should not be carried out at once, but to cut a separate one part.
In blanks that differ in large thickness, all cuts should usually be straight. If there is a need to make a certain circuit of a curvilinear type, then you must first make segment rectilinear through cuts and remove unnecessary parts. When working with metal should not be pressed too press. Too big efforts may cause breakage.
Before starting cutting, glass should be dealt with the characteristics of such a transparent and kind of fragile material. Glass has quite good characteristics of strength, although it may seem, at first glance, that it is not. He has not only good strength, but also hardness, heat resistance, as well as good properties of an optical nature. Cut the glass bottle of the house just so it will not work. It is necessary to have a specific tool and certain conditions.
It should be said that the glass with the help of a cornering machine can be exclusively sawing. And you can do it quickly. But for this, it is necessary to have a disc made of steel, equipped with a deposition of diamonds for cutting concrete, granite or other building materials. When cutting, the cutting area should constantly pour cool water. Given the high strength of the glass, there will be a lot of heat in the cutting place. Big temperature will be bad on the edges of the saw and disk. And thanks to cooling, the cut will be smaller and spraying from diamonds will not get quickly. This method allows you to work with almost any kind of glass of household direction.
Work with artificial and natural stones
A number of categories of stones, including marble, concrete, granite and others have high strength. With such not in all cases can even handle the most beneficial Bulgarian. For cutting stones should be used by special cutting devices. We are talking about cutting variants from diamonds, which have already mentioned earlier. It is based on a plate of high strength steel, on the outer part of which certain segments are located. Tooth segment tips are covered with a crumb of high strength made of diamonds. When working, such circles face strong heating, due to which there are special slits for cooling, which are called perforation. During a twist, cold air passes through the rosters into the cutting area, which cools the material with which the work is underway, and the disk. Diamond options are easy to cut the strongest finishing stones with a natural basis:
But artificial decisions will also be well cut in such a method. As with the same concrete, it will be very important to have its age, as the older, the usual is stronger. It also matters which filler was used when creating material. In general, only a powerful, truly professional corner car can help with concrete, which has abrasive discs on a diamond base and the possibility of switching speeds. Let’s say that today there are only two techniques cutting stones of natural and artificial origin:
In the first case, there is a large amount of dust. In the second case there will be a lot of dirt. Preference to this or that method should be given depending on the amount of work. If we are talking about some disposable work, you can easily do the dry option. If the works are significantly more, then you should resort to the second option. In addition, the use of water allows you to reduce dust formation, improve cutting conditions and reduce diamond disk wear.
How to cut a balloon?
Many of us are faced with the presence of an empty gas cylinder or oxygen or propane. Most people will throw it away, although it can create a lot of useful. But in this case, without cutting the metal it will not work out. This instruction is generally suitable for any cylinder, be it gas, propane, oxygen or some other. First you should prepare a number of materials and devices, namely:
- Bulgarian with a cutting disc;
- Metal hacksaw;
- Watering hose;
- a construction worker;
- Directly used balloon.
So, if there is everything you need at hand, you can start performing the work in question. First you need to release gas residues from the balloon. It is necessary to move the valve to the open position before the stop and make sure that there is no gas residues inside the container. If there are no sounds, then you can lamin the output hole of the valve and in the absence of bubbles it will be clear that inside is empty.
Put the sideball of the side to be more convenient to cut it. First we spill the valve. We take a hacksaw and saw the item from brass as close as possible to the place where the dock with the main capacity is carried out. There will be no more than anyone’s help so that while you are working on the cut, another person lied water to the cut-sized place so as not to start flying sparks. Now the container should be filled with water using a funnel. As it fills it, the capacity should be shaking, so that the remnants of the condensate disappeared from the walls. Water should be pouring to the top, after which everything must be poured. It is better to do this in where there are no residential premises, since the remains of some gases have a very sharp unpleasant smell.
Now proceed to the cutting container itself. We will need Bulgarian. The thickness of the metal in the cylinder usually does not exceed four millimeters, due to it with the help of a cornering machine can cope with it for 15-20 minutes. To break through passed safely, you should not wait for drying the inner surface of the cylinder, and immediately you should start sawing the balloon while it is wet. Water on the walls will serve as a lubricant for disk.
How to sharpen chain chainsaw?
The sharpening of the chainsaw can only be performed by the user with extensive experience in using a corner-gland machine, which is familiar with the rules for sharpening chains for electric and chainsaw. Such work is required from time to time if you use actively chainsaw. It is best to carry out this with a small grinder equipped with a protective casing.
Bolding must be carried out directly on the chainsaw. Also in order to endure chainsaws, it should be noted the start of the sharpening of the first teeth. We set a special sharpening disk on the grinder, which usually has a thickness of about 2.5 millimeters. In this process, good vision is necessary and the most accurate movements of the hands with the grinder, in no case do not impose physical damage to the carriage of the chain. If the sharpening of the saw chain with the help of the grinder is correct, it will serve for another 5-6 sharpening.
Paul grinding features
Another area where the use of a grinder may need – when it is necessary to grind the floors made from concrete. Now this process is becoming more popular, because it gives the flooring a spectacular and pleasant appearance. The grinding of the floor covering from concrete with the use of a grinder will be one of the types of processing, which is needed in certain cases to remove the old coating and leveling the base, so that you can make a screed before applying various impregnations, paints and so on.
The preliminary grinding procedure should be carried out 3-5 days after laying the foundation. And the final grinding should be carried out after the final solidification of the floor surface. With the help of the process under consideration, it is possible to remove all sorts of pollution, to dissolve areas that are deformed or in which there are cracks, influx or chip. And after grinding, the floor of the concrete will look more fresh and is distinguished by increased adhesion characteristics.
To carry out the grinding of the concrete, the average in its characteristics is a corner-lining machine with a diameter of a disk 16-18 centimeters, having a power of about 1400 watts. To obtain a good result, do not hurry with work. Usually, the best filler for grinding will be a mountain crushed stone of metamorphic type or fine-flow.
If there are any coatings on concrete, they must be dismantled in order to dissolve the entire plane. If there are shrinkage seams or cracks, they need to be embedded, after which it is additionally polished. Before the start of the work, you must make sure that there is no reinforcement in the upper layer or a metal-type mesh with reinforcing functions.
Concrete grinding should be performed extremely 14 days after the final tight drying. In this period, the material is gaining strength. After the preparation, you can carry out grinding. First, the floor should be processed using a special mixer, which reacts with calcium hydroxide. On the surface of the material for this reason, a fusion of a binding type on mineral-based, closing pores and its strength and moisture resistance will appear.
When applying discs, which have a grain rate of about 400 and higher, it is easy to form a fairly strong layer of concrete, which will withstand quite serious loads. This is the final stage of the work, after which the surface is no longer necessary to process. If you want, you can only polish it when using big grain diamonds.
As it was possible to make sure Bulgarian is a rather dangerous tool. And in order to avoid injury, it is necessary to follow certain rules for handling it:
- Various kinds should be applied;
- Prior to the implementation of the work, the reliability and loyalty to the fastening of the casing should be checked in order not to take off during the work, because thanks to him, sparks should fly from a person, and if the casing disappears, they can start flying into it;
- It is necessary to hold firmly to hold the instrument in hand, in order not to slip away during the work;
- It is necessary to use only entire disks without flaws and only to work with some material;
- The defense shield should be kept between the circle and man, in order to have protection during the deformation of the circle;
- Before the start of the work, you can check the operation of the tool at idle for about a minute;
- Before use, all the nozzles should be used in order to determine how suitable they are for use;
- Working nozzles, so that they did not flip, it is necessary to constantly fix it;
- If there is the ability to adjust the rotational speed, then the turnover is required to be recommended for cutting or grinding the working material;
- Cutting should be carried out exclusively on certain revolutions;
- So that the cutting takes place without dust, during the process, water should be pouring into place where the cutting process is carried out;
- From time to time there should be interruptions;
- Only after stopping the circle you can postpone the tool;
- If the working nozzle jumped for some reason, then the grinder should be turned off immediately;
- Singing wood should be very careful, because the falling on the bitches can cause a reservoir tool;
- The power cord should be located aside from the part that rotates, in order not to interrupt it or was not caused by a short circuit;
- It is impossible to install nozzles from the circular saw due to the fact that they are calculated on the other speed of spindle rotation.
