Jigsaw design and principle of operation

Electric jigsaw has a fairly uncomplicated device. In order not to run with minor malfunctions in the workshop, it does not hurt to understand what structural elements consist of this electric tool.

Let’s consider the device and the principle of operation of the electric jigsaw, without going into technical details:

The basic elements of an electric jigsaw

1. The steel or aluminum guiding plane-support, also known as the base plate, sets the desired cutting angle for the tool and keeps it in that position at all times, so that the cut of metal material is made as accurately as possible. Most often you can select any angle value in degrees up to 45 degrees, but there are some jigsaw models with fixed values to choose from.
2. Any electric jigsaw is equipped with a special saw blade that makes fast movements perpendicular to the plane of the material to be worked, with a speed of 53 revolutions per second.
3. At the heart of the driving system of the tool – a powerful electric motor from 200-ta to 900-ta watts, which turns the lifeless saw into a high-speed monster.
4. Basically, all jigsaws are equipped with a mushroom leg-like holder with which you can hold the jigsaw in position throughout the work.
5. All models of this tool have a supporting roller or jaw that guides the movement of the saw.
6. Finally, any modification of the electric jigsaw is characterized by a special button that allows the tool to work, without constantly holding the start.

In addition, many jigsaw models have some additional useful details to ensure comfort at work.

1. Quantitative control for cutting – The number of blades of the jigsaw is set individually for each material group, so that a qualitative and fast cut is obtained: the smallest degree of oscillation of the pendulum motion corresponds to the cutting of hard materials, softer and more plastic materials – on the contrary. This device greatly simplifies the work process.
2. Transparent plastic saw blade protection – provides additional protection for the user against mechanical damage.
3. The mechanism that allows chip evacuation automatically.
4. Improved electronics With constant current flow characteristics (strength, resistance, power, voltage).
5. The lighting device.
6. Built-in protective equipment, sound and vibration mufflers to make work quieter and more relaxing.
7. Various case coatingsto protect the jigsaw internal parts against impacts.
8. jigsaw quick cleaner jigsaw dust extraction with a vacuum cleaner.
