How to choose the right circular saw
Mechanized saw — the most popular type tools for work in the country. The range of possibilities is very wide: from felling tall trees to figure carving of ice figures. The latter, of course, exotic, but also has a place.
What are the saws
Latitude facing saws tasks spawned a variety of schemes. However, for us gardeners, there are two classes of structures, a fundamentally different form of working bodies. And here we should distinguish between these types of machines is that in the future they are not to be confused:
Circular saw blades — technically competent title tools using as a working body of the saw blade.
A chain saw is the General name for tools, work on which is a chain with cutting teeth. Depending on the type of drive (electric motor or internal combustion engine), the latter are divided into electric and petrol saws (they are often called chain saws that, strictly speaking, wrong). But we will talk about them another time.
Manual circular saw
This is one of the first tools that acquires a cottager. We can say that this car is "tough" things. In renovation and construction work hand-held circular saws (colloquially "circular saw") used for longitudinal and cross cutting of boards and beams, and MDF, chipboard, laminate and even aluminum.
The main advantage of circular saw blades is the relative ease of implementation, with its long and smooth cuts. It is indispensable when cutting large quantities of boards (for example, in the manufacture of edged boards). Is this car noticeable drawback to cut along the curve line circular saw can't.
The design of the "circular saw" at first glance, is quite simple:
an electric engine located under the body
reducer,
saw blade, enclosed housings,
flat wide base with a directing emphasis
and riving knife behind the disc.
However, among the specialists of the disk saw is considered to be a very complicated tool. The point is that here it is necessary structurally to provide reasonable security requirements (admit, saws are quite traumatic), as well as to maintain precise setting of the saw blade.
Do we need more power?
The main characteristic of the circular saw — power of the engine (the "circular saw" installing electric motors). High power saw for cutting, for example, a rough piece of wood, selecting the maximum size of the disk. But large capacity inevitably entails an increase and weight, and price.
On the other hand, the power reserve is a useful thing. Powerful motor provides better stability of the speed allows faster cutting of thick material. This parameter "conveyers" are divided into three classes:
up to 800 watts;
from 800 to 1200 W;
more than 1200 watts.
The saw served you longer, and the engine failed due to overheating, choose a model with a binding reserve power.
Do we need high speed?
The power of the engine and the rotational speed of the disc determine the performance of the saw. The rotational speed depends on the quality of the performed cutting. However, it should be noted that for different materials the optimum cutting speed will also be different. Thus, polymers with a low melting point is best to handle at low speed (so as not to melt off the edge), and solid wood and MDF at high.
For targeting a desired material and apply the regulation of frequency of rotation. In other cases, this option remains unclaimed. Therefore, saws, often only one frequency of rotation of idling around 5000 rpm So the advice is for truckers, not aspiring to the heights of creativity pil: purchase a single speed saw.
How does a circular saw blade
The quality, speed and ease of work defines the cutting tool, in our case a circular saw blade. They differ in:
mind processed material (wood of different densities and thicknesses, plastic, aluminum profile, etc.);
the size and shape of the teeth and their angle of sharpening.
Disks with a small number of teeth (12-16) cope well with fast work, but the results will look relatively scruffy. As a rule, with increasing number of teeth (and there may be more than hundreds) increases the cut quality, but it reduces the cutting speed.
The cutting discs have several radial compensation of the slits, which prevent the possible buckling in the case of excessive overheating and, as a consequence, additional vibrations and noise.
The diameter of the cutting disc is the main consumer option "conveyers". However, few know the size of the circle: it is more important for the user's maximum cutting depth. In most models, it is about 40% of the diameter of the disk.
Read the information on the disk: everything is written
Information about the parameters of the cutting disk provided on its flat side. You will often see a symbol consisting of three digits, where:
the first digit corresponds to the outer diameter of the disc in millimeters
the second reports the number of teeth,
the third equal to the diameter of the shaft which turns the disc itself.
In addition, specify the maximum number of revolutions per minute, often cutting width and, most important for us, the material for which the blade is intended.
View "horse" in subzoba disks are made of hard alloy with a diamond grinding. For different types of materials designed by the special design of the teeth, the form and type of sharpening is optimum for the cutting process. For example:
For sawing of wood used wheels with teeth of the form ATB.
If the wood can be nails or have to "deal" with a fibrous plate on cement-based — take drives FWF-teeth;
laminated chipboard with double-side coating and aluminum construction easily give little teeth-incisors TCG.
Finely toothed precision drives are very versatile. They cut not only wood but also glass fiber reinforced plastics, and nonferrous metals.
Sawing on the battery When working circular saw consumes a lot of energy. However, modern battery technology has allowed to equip it "battery". Cordless circular saw good there where hard to pull "electricity". For example, when performing the roofing work will not have to pull the multimeter on the roof of the extension cord, always underfoot.
Find a job for battery models and in extremely wet areas, for example the basement, where often "water on the knee". In this case, the main argument for their use is safety. After all, in the wet room 18 In the voltage from the battery even in the most extreme case will not bring harm to the operator. You can not say about the 220 V network power supply.
As the saw ensures your safety?
Circular saw — a really traumatic thing that must be carefully and respectfully handled. The designers have done a lot to eliminate accidents with this fast and sharp car.
Here are a few examples of such concerns:
Cutting disc top is closed with a stationary safety cover, and bottom movable spring-loaded sector, which hides the drive until the moment of contact of the saw with the saw in the workpiece. When feeding the tool forward a little to turn the pie casing, and a sawn billet itself will push back to reveal the saw blade. After removing the "buzz-saws" with the material of the lower portion of the housing through a compressed spring automatically returns to its original position.
The tool is equipped with a special safety device with a slip clutch. It is triggered when a possible blade from jamming in the workpiece. This is often the case with gambling beginners. In this case, the disk stops spinning, and the engine continues to run. And best of all, doesn't burn or lead to unplanned expenses.
Protection against accidental firing is done by setting a special button next to the launcher button. To turn on the saw, you should press them simultaneously. To perform such a combination of different movements by chance, perhaps, impossible.
Another great invention, the braking block shaft after the engine is turned off. It limits the "coasting" of the disk and stops it immediately after the user removes his finger from the trigger button.
Two useful advice
To replace the saw blade just press the button of blocking of the rotating shaft, and the disc will be removed with the help of wrench included in the package. If the lock option is not provided, it is necessary to use two wrenches, one of which is fixed shaft, and the other removable disk.
If necessary, you can cut a very large piece of material, making the kerf on both sides. After all, it is not necessary that the saw blade passed through the workpiece through.published
