A jigsaw machine is a device on which cross, longitudinal and angular cutting of workpieces is performed, as well as figure cutting of decorative elements. It is used in carpentry and woodworking production.
Some models can be equipped with an air pump that blows the sawing site, so that you can maintain constant control over the operations and markings.
The principle of the jigsaws is as follows: the workpiece is fixed on the desktop, then the cutter performs reciprocating motion. There are some models on which the table can be tilted, lowered or raised for different parts of the saw blade.
Jigsaw machine easily cuts thick wood, and with excellent quality of the treated surface. Such a device allows both hands to remain free to control the feed of the workpiece. Thanks to this, it is possible to do the work accurately and, if necessary, to cut fairly steep bends. The jigsaw machine has gained its popularity due to safety in operation.
The thickness of the workpiece
As a rule, even relatively small jigsaws can cut 50 mm of wood, and more powerful models can handle twice as much thickness.
Regardless of what material the work desk is made of (extruded or cast metal), it must first of all be smooth, rigid and flat. In virtually all jigsaws, the table can bend to perform oblique cuts, and in some models it can be raised and lowered so that you can use different parts of the blade as the file wears.
A small, asynchronous 100-watt electric motor for a jigsaw machine is capable of developing a web speed of approximately 1600 strokes per minute. There are models, some can set different values of speed.
Length of the course of a file
Despite the fact that the table jigsaw machine is able to cut quite thick blanks, the course of the web (vertical movement) is rather short. As a result, if you cut a lot of thin materials, then only a small part of the file is blunt at the file. For a more rational use of the length of the canvas, you can periodically put plywood or chipboard on the table.
On the jigsaw machine, as a rule, very simple fencing, usually consisting of 1-2 bars from wire or plastic transparent screen. It is intended to prevent the contact of fingers with the file. When sawing thick wood often used jigsaw without fencing. Some models are offered fencing only as additional equipment.
Sometimes machines are equipped with a clamping device. It is used to prevent the vibration of thin sheet material so that the workpiece is not lifted from the table by the movement of the web. Automatically spring strap when it is raised rises billet.
One of the quality indicators of desktop jigsaws is the presence of a pipe for cleaning from sawdust, which is installed behind the canvas. Under pressure, air is blown through it, blowing away sawdust lying on the markings.
Jigsaw jigsaw machine
This model is a great solution for creativity. The equipment is intended for sawing of workpieces of wood and plastic under oblique and right angles, angle and radius. Used typically for smaller operations. Desktop can be tilted at an angle 0-45 degrees, whereby it is possible to perform sawing at an angle. For a more accurate performance in a set of jigsaws machine included side focus with a protractor.
This high-performance model is designed for cutting out contours along various trajectories, both internal and external, including curvilinear, in wood of any hardness. The cutting vertical blade performs high-speed cutting. Blade speed can be adjusted within 400-1600 rpm.
Machine power - 90 watts. The model is equipped with a fairly comfortable desktop 410x254 mm with the ability to adjust the angle of inclination by 0-45 degrees to perform more complex sawing.
