In Toral we are experts in metallic transformed of the highest quality and we have the machinery more advanced and a highly qualified team for the execution of your projects. Within the teams for machining by cutting and punching, we have band sawsWhat are band saws and how do they work? We'll tell you in this article!

What is a band saw?

The band saw It is an indispensable tool in any machining workshop. Your ability to perform Very precise and fast cuts on various materials makes them a great alternative. How do band saws work? Before telling you the details, you should know that this is a machine that uses a metal sheet, provided with a continuous serrated edge. This moves on two or more rotating wheels.

The band or ribbon (saw) is specifically designed for cutting materials with great precision. In addition, it can be adapted to different types of applications, depending on the type of saw tooth and the blade material. In this regard, there are Two main types of band saws:

• VerticalIt is generally used to make irregular or curved cuts, as it allows greater control over the piece to be machined.
• HorizontalThis type of band saw is used to make straight, precise cuts in heavy materials such as bars or tubes.

How do band saws work?

He basic operating principle of this machine tool is very simple. The toothed band or belt rotates continuously. This allows the teeth of the blade to make direct contact with the material and cut through it. To understand how band saws work, it is necessary to explain the machining process stages:

Continuous movement

The toothed blade moves continuously in a circular motion on the wheels of the machine. This constant movement allows reduce friction and facilitates a uniform cut. The speed of the band can be adjusted, depending on the material to be cut, which is essential to obtain smooth cuts. clean and precise.

Chip removal

To better understand how band saws work, we must tell you that they are machines that perform machining by chip removalThat is, the material is removed gradually by the action of the saw teeth. The material is expelled through small pieces known as shavingsThis type of machining allows for precise cuts with clean finishes.

Adjusting and tensioning the band

To ensure that the cut is efficient, the band tension must be properly adjusted. A band that is too loose can cause deviations in cutting, while a band that is too tight could break or cause a unnecessary wear and tear. When the band is adjusted to a suitable tension, the saw teeth make the cut in a precise and uniform, which not only prevents damage to the part, but also to the machine.

Why use band saws in machining?

These are the benefits to use the band saw as part of machining work:

• VersatilityBand saws can cut a wide variety of materials such as metals, wood and plastics.
• Precision. Due to the stability of the band and the possibility of adjusting its speed, it is possible to make precise and high-quality cuts.
• Minimum waste. Unlike other cutting machines, saws generate less waste. This allows them to be made more efficient in terms of materials.
• DurabilityThey require less maintenance, are more durable and wear less when compared to other types of saws.

As for the maintenance of these machines, it is important to note that, although it is minimal, it is necessary to do so. The band must clean frequently to prevent the accumulation of chips and waste; it is also essential Check the tension of the blade to adjust it and, of course, perform the lubrication of moving parts. Lubrication is essential to reduce friction and prolong the life of the machine.

Finally, although band saw blades are durable, over time and use, teeth wear down and lose their effectiveness. It is essential, as part of maintenance, sharpen the blade regularly or replace it when necessary.
