First of all, it is necessary to determine which circular saw is suitable for a particular job, depending on the design of this tool there are:
- Stationary – really a system, which is a saw mounted onto a framework. Requires free space at moyakovka.ru the workshop, and on occasion another room. Made such a circular saw for permanent processing of timber, and in huge volumes.
- Table – the previous version in miniature, installed on another workbench or desk, is also employed for sawing a large volume of wood, as an instance, during the construction of the bath.
- Guide – a portable device, intended for processing workpieces in distinct planes. This is the most common kind of circular saw, however the least powerful of this clarified. When working, it requires periodic remainder, and is used for sawing small quantities of material.
Hand-held instrument is much more versatile than stationary variants. It costs much more economical, but under certain conditions can cope with the exact tasks, though with less efficiency. When picking it, you ought to be guided by the standards below.
Power
According to the type of power supply, circular electrical saws are divided into 2 classes:
- Networked – they work from a national electric system of 220 V. If we talk about professional machines, they require a line of 380 V. The disadvantage of this connection alternative – the need to have an energy grid at the place of work, as well as some inconvenience of operation because of the cable.
- Vacuum – operate in stand alone mode, also need the presence of a socket, but to charge the battery, so their radius of performance isn’t restricted by anything. Depending on battery capacity, they can work on a single charge not more than 50 minutes.
The second choice is sensible to buy only if for some reason it is not possible to use the mains viewed. Form of work
Standard circular gears are designed for sawing wooden workpieces at different angles, but there are also specific versions of the tool:
Submersible saws come in handheld and stationary versions. Their difference lies in how the saw blade at the initial position is within the workpiece, capable to descend into its centre. This allows you to begin cutting off not with the edge of the substance, cut holes.
Metal round saws are powerful models which are equipped with stronger or abrasive disks. Capable of cutting sheet steel, plumbing, profiles. A number of them handle wood both well.
The diameter of the disc directly is based upon the power of this saw’s electric motor. The stronger the tool, the larger the disk it’s ready to rotate, the more stable the spinning frequency of the latter, the longer the duration of constant operation, the less likely the wedge. Moreover, powerful saws allow you to process heavier material, but they also are thicker. Thus, by way of instance, models at 2 kW generally weigh 7 kg, while 1.2 kW – approximately 4 kg.
According to the energy saws can be broken up as follows:
How to choose a circular saw: professional hints
The larger the diameter of the disk, the stronger the electric motor needs to be, the heavier the workpieces the saw can use. Seating diameter is just another parameter that decides if a specific disk will match the chosen saw. The most usual criteria below would be 20 and 30 mm.
At greater speeds, less torque is required for sawing, meaning dense substance is much easier to handle. Remember that using higher RPM the warmth of this material in the place of contact with the saw raises, the same laminate or plastic requires less RPM. Ideally, it’s far better to pick a saw with flexible rate.
