Circular saw

A circular Scie is a tool of cutting equipped with a disc (or blade) cogged, actuated by a machine.

The March 27th 1816, Auguste Brunet and Jean-Baptiste Cochot deposit the Brevet circular saw. At the origin, the first circular saws, actuated by water, cut only the Bois. Now, they can also cut out other matters while changing type of blade.

A circular saw can be either stationary (fixes) or portable .

Stationary saws

The blade of such a saw is embedded in a Table. The blade passes through a slit envisaged for this purpose. A mechanism is designed to regulate the height of the blade which exceeds above the scheme of work, like its slope to allow cuts of skew (between 0° and 45°). It generally has a guide parallel with the blade and a guide sliding perpendicular to the blade, which makes it possible to carry out longitudinal and transverse right cuts. It is the part to be crossed which comes to the meeting from the tool.

It makes it possible to make regular and very precise cuts.

There exists several type of blades being different by their diameter or their number of teeth, adapted to operations of specific cuts on wood.

The Blade to be output or cut up being used to cross across fibers, generally has forty teeth to guarantee a cut of quality, practically without wood glares. Wood offering less resistance to the longitudinal section, the blade to split to cross in the direction of fibers, has 16 or 18 teeth, sufficient for a good completion.

The blades combined for the mixed operations of flow and délignage comprise approximately 24 teeth, and exempt the operator to change blade according to the operation.

Portable saws

Such a saw is a very handy portable tool: contrary to the fixed saws, it is brought towards the object to cut out, and not the reverse. It has a bearing surface (through which the blade passes) and a guide to make it possible to make relatively precise cuttings. The blade in general is directly fixed on the axis of the engine.
