The circular saw is one of the tools used in carpentry, and can also be applied to cut materials such as plastics, non – ferrous metals including concrete, plaster, or. It consists of atoothed disc which, turning quickly, allows the cutting of materials.
The basic structure of a circular saw is formed by:
• A metal disc , bliss itself saw, which has in its teeth sharp edge.Usually they are made of stainless steel. Some models the carbide teeth tips that make them more resistant. The size of the disk determines the depth of cut can be performed, while the size and arrangement of the teeth varies according to the material and type of cut that they want to work.
• An engine which drives the mechanism which allows rotate the saw to make the cutting motion. Usually, electric motors are used, although some models powered by gasoline engines, and large saws in sawmills driven by water, using the same principle that was used in the mills.
• A structure that allows you to manipulate the tool access controls and protects the user from the most common hazards.
The different types of circular saws differ mainly in their structure and form , as all operated on the principle of rotating a toothed metal disk at high speeds. Click here for table saw reviews.
Types of circular saws.
The circular saws are tools to make straight and quick cuts . They are equipped with anelectric motor whose power can range from 500 to 1400 W, reaching speeds of over 4500 rpm and allow cuts of up to 75 mm thickness in different types of materials, of which the most common is wood. Around the mountain there is a protective housing to manipulate the saw without excessive risk, as it covers the edge of it and allows discarding waste sawdust in a controlled manner. They are equipped with a lock switch or prevents sure the tool is operated by accident, a guide that helps us move it straight up, and a base which controls the tilt of the saw. Some models are equipped with bags that allow collect sawdust.
Table saws, or bank:
These woodworking tools use the same principle that large sawmill saws, machinery remainsfixed and the operator is who should bring wood to the edge to make the cut. The toothed disc protrudes above the surface of the desk, which provides support and guidance for the material. Some models feature mobile supports that can regulate the depth of cut in wood, or adjust the cutting angle. It is used for fast cuts in large pieces.
Miter saws or miter:
A circular saw is mounted on a structure that remains high with respect to the worktable. This structure allows movement of the saw from the top down , using a crank on which the operator must exert pressure. This type of woodworking machinery enables fast, accurate crosscuts into a piece of material. They are commonly used to break long pieces of wood , allowing multiple make precise cuts in seconds. Miter saws typically operate at an angle of 90 ° with respect to the worktable, although this angle may be varied according to the needs of the operator.
Saws radial arc Such saws, miter like, is also mounted on a structure that maintains high relative to the plane work. The structure has an arm which allows a circular motion with the saw. The radius of rotation can be adjusted by the operator, as the depth of the cut being performed. They were originally designed to cut long pieces of wood and make circular cuts, before the appearance of the mountains that are currently used.
Sierra sawmill: These tools consist of large toothed metal disks that move by using larger engines. The saw remains fixed, and the pieces of wood large are mobilized by using a conveyor belt . This method is used to cut long boards, even from whole logs .
Panel saws: In this case, the saw is mounted on a structure with rails that allows controlling the movement of it. Some mechanized models allow control the movement of the medium maquinariapor one computer program , ensuring accurate cuts. Panel saws, depending on their design, can be horizontal or vertical .
