What is a chainsaw? What types are there? Uses

Saws are a very popular tool used today, often used for construction, assembly and repair. So what is a saw, what types and uses? Let’s find out with Tnhelearning.edu.vn now!

What is a chainsaw?

A saw is a tool used to cut wood and some other materials depending on the needs of the user. Saws are hand tools that can use electricity or batteries to cut materials and often possess a powerful capacity, saving time for users than traditional hand saws.

Working principle of saw machine

Each saw will have a characteristic structure and a slightly different operating principle, but in general will have the following basic operating principles:

First, the machine will be supplied with electricity from the mains or battery, transmitted to the motor and make the motor move. As a result, the intermediate drive shaft will start to rotate, and then transmit the force to the saw blade shaft. Finally, the saw blade will move and the user begins to manipulate.

Types of saws and their uses

Circular saw machine

A circular saw is a machine that uses a circular saw blade , operating on the principle of rotating the saw blade, so that it can cut, cut horizontally or diagonally on the wood grain.

Circular saws usually have a large capacity with high idle speed, which helps to cut wood and some materials quickly, and gives flexible cutting on a variety of materials and shapes.

In addition, most circular saws are equipped with a saw angle adjustment, cutting to help you create many different shaped finished products.

Metal band saws

A circular saw is a type of saw that uses a blade saw , moving up and down to cut materials along the vertical axis, so that not only can saw in a straight line , but also cut wood in curves, bends and oblique cuts .

The circular saw is often used to cut wood (especially decorative pallet wood and industrial plywood of moderate thickness), cut the curve at the corner of the table and the last cut line is parallel to the wall, even can be cut. floor tiles and some other metals .

Sword saw machine

A sword saw is a type of saw that uses a long blade , made from carbon steel material with high impact resistance.

Saw blade with a reciprocating mechanism for sawing common woods , large boards, rods or tubes and some other metals.

Table saw machine

Table saw is a type of saw with a table-like design , consisting of one or more saw blades divided into the main saw blade and the auxiliary saw blade .

The auxiliary saw blade has a small diameter, which rotates faster and cuts in the opposite direction of the main saw blade to minimize chipping at the bottom edge of the material. Meanwhile, the main saw blade will rotate in the opposite direction and take over the function of cutting the entire thickness of the material.

In addition, users can slide the construction material on the tabletop , making the sawing operation faster and less laborious while ensuring a beautiful and accurate cut. The table saw can cut large and thin wood panels, shape, cut corners, …

Multi-angle saw

The multi-angle saw has a table-shaped design , which can support users to cut/saw materials with flexible cutting angles such as 90-degree straight angle and 45-degree tilt angle .

The cutting table is mostly made of metal with good rust resistance and bearing capacity, the handle is designed in a D-shape and has the ability to adjust the angle flexibly to cut materials.

In addition, some multi-angle saws are also equipped with a dust bag to minimize dust flying during material cutting. Multi-angle saws often cut wood, aluminum and some other metals.

Chain saw machine

A chain saw is a saw that uses a long bar saw blade surrounded by a chain saw. This saw is often used to trim branches, cut down trees, cut wood grain , and even cut ice and concrete .

Circular saw

A circular saw is a specially designed saw that can move the circular saw blade in a circular motion in a stationary state when cutting (for vertical circular saws) or in circular motion at high speed (for circular saws). horizontal circle).

This type of saw has high working efficiency, can cut soft materials (such as wood, stainless steel, aluminum, …) with straight cuts, bevel or diagonal cuts, and heavy – thick metal materials (including round, rectangular, square, hollow or solid tubes).

Hopefully, the above information will help you somewhat understand what a saw is, what types are there, and what are the uses of each type. Thereby, you can easily choose the saw that suits your needs in life and work.
