Electric Jigsaw : everything about the instrument

history, types and operation

jigsaw was invented in 1946 by Albert Kaufman, who replaced the sewing machine needle on the blade.Since 1947, he appeared in the sale, and in 1954 it bought the patent for the company Bosch .The main difference lies in the jigsaw of its functionality and the quality of the cut.Depending on the operations carried out by jigsaws are divided into several types:

• household - is needed to perform simple operations and has weak capacity and low price;
• Professional - easily tolerate high loads, productive, easy to use, able to work 8 hours;
• Industrial - meets all the requirements of professional electric tools necessary to carry out a large number of tasks.

electronic jigsaw consists of a body with a flat platform and handles.Inside there is a motor and the mechanism leading to the blade movement.Stationary jig does not have handles, and the platform is placed on top.The guide is arranged vertically in front of the engine.In the lower part there is a retractable blade that moves when the engine is making the cut.

operating principle is as follows: the clamps securely attached sawing (cutting element) in the slide.Reciprocating movements are performed at up to 3000 strokes (adjustable).Thanks to the support platform, jigsaw focuses on sawn item that provides for an accurate job.To protect the operator the dusty canvas flap closed.

Advantages and disadvantages

Like any tool, jig saw electric hand has advantages and disadvantages.Let's look at them.Among the advantages it is certainly true that is adjusted extensive release of a wide variety of saws, which can work with a variety of materials due to various shapes of teeth and pitch adjustment.

It affects the purity of cut and the possibility to use the tool to perform a large number of operations, including the plasterboard.Fastening web occurs on one side, thereby enabling cutting at any distance from the edge parts, and it does not break the web.Work in this tool is much easier than mechanical.

main disadvantage in securing the blade with only one hand, which causes difficulty in manufacturing thin saws such as that of mechanical jigsaws.This affects the increase of the minimum radius of bending the saw line.The process of sawing thick parts slows down due to a short web travel, which degrades the output chips.

Tip!Jigsaw Wood Electric, as well as mechanical, has its pros and cons before buying should carefully assess the scope of the future application of the instrument.

main rules when working

At first glance, the work with the jigsaw looks simple enough, but professionals know that you can ruin the material and the instrument itself without certain skills.Here are a few tips for working with a jigsaw:

• Always make sure the blade condition (dusty or dull to be changed, because they are not only bad cut, but also provide an additional load on the drive);
• Do not apply pressure to the tool to accelerate the work, it will lead to dust, overheating and failure of the blade;
• For each material type, choose the appropriate blade;
• To make a long propyl, use the guide rail;
• wood need to use the maximum speed of the drive.

Important!Avoid sawing!Be sure to lock the item, it will free hand, make cut better and relieve the cutter from heavy loads.

Finally, when sawing laminated chipboard frequent chipped.To resolve this issue, turn off the pendulum stroke setting it to 0. It is better in this situation is to use a clean blade stroke.Also, it will be useful when working with hard materials - it will increase the life of the blade.
