First of all, It’s necessary to Ascertain that circular saw is Appropriate for a Specific job, as by the design of this tool there are:
- Stationary – really a machine, which will be a saw mounted onto a frame. Requires free space from the workshop, and sometimes a separate room. Made such a circular saw for permanent processing of lumber, and in massive volumes.
- Table – the prior version in mini, installed on a separate workbench or table, is also employed for sawing a large volume of timber, as an instance, during the construction of the tub.
- Manual – a portable device, intended for processing workpieces in various planes. Here is the most frequent kind of round saw, but the strongest of this described. After functioning, it takes periodic rest, and is utilized for sawing small amounts of substance.
Hand-held tool is much more versatile than stationary variants. It costs considerably more economical, but under moyakovka.ru certain conditions is able to cope with the very same tasks, even with less efficiency. When choosing it, you ought to be guided by the standards below.
Power
According to the type of power source, circular electrical saws are divided into 2 classes:
- Networked – that they operate from a national electric network of 220 V. If we discuss professional machines, then they require a line of 380 V. The disadvantage of the connection alternative – the necessity to have an energy grid in the area of work, in addition to some inconvenience of operation because of the cable.
- Cordless – operate in stand alone mode, even need the presence of a socket, but to charge the battery, therefore their radius of performance is not limited by anything. Depending on battery capability, they could work on a single charge not more than 50 minutes.
The second option is logical to buy only if for any reason it’s impossible to use the mains observed. Form of work
Submersible saws – come in handheld and stationary versions. Their difference is in the fact that the saw blade in the initial place is within the workpiece, able to descend into its centre. This permits you to begin cutting off not with the border of the substance, cut holes.
Metal circular saws are powerful models which are equipped with more durable or abrasive disks. Capable of cutting sheet metal, plumbing, profiles. Some of them manage wood equally well.
The width of the disk directly depends on the power of this saw’s electric motor. The more powerful the tool, the larger the disc it’s able to rotate, the more secure the rotation frequency of the latter, the longer the length of constant operation, the less probable the wedge. Additionally, strong generators enable you to process heavier material, but they also are thicker. So, by way of instance, models at 2 kW generally weigh 7 kg, while 1.2 kW – approximately 4 kg.
According to the energy saws could be divided as follows:
The bigger the width of the disk, the stronger the electrical motor needs to function, the heavier the workpieces the saw may work with. Seating diameter is another parameter that determines whether a specific disc will fit the selected saw.
At higher speeds, less torque is needed for sawing, which means dense material is much easier to handle. Remember that using higher RPM the temperature of the material at the place of contact with the saw increases, exactly the same plastic or laminate requires less RPM. Ideally, it’s much better to select a saw with flexible speed.
