Band saws are used for sawing (straight or curly type) of various materials.
Band saws are used for sawing (straight or curly type) of various wood materials.
The main scope of these tools is construction and repair, as well as furniture manufacturing.
The wood is sawn on special belt machines using a saw belt that is attached to pulleys.
The machines can be vertical and horizontal.
In addition, band sawing is distinguished on carpentry devices.
With the help of them, the workpieces are sawn along a drawn line (some machines provide mechanical feeding of materials).
Sawing is also possible on dividing machines.
By means of this technique, the division of humps and boards is carried out.
The machines provide for mechanical feeding using vertical rollers.
With the help of log sawing devices, the cutting of the log is carried out.
In this case, the material is fixed on a trolley, which is attached to the rail track.
Currently, horizontal band sawing devices are no less common (they are used for individual cutting of logs or cutting wide humps).
Band sawing has significant advantages over using frame saws.
If we take into account the rather high stress state of the belt device, the cutting speed is 70 meters per second.
As for the feed rate, it is 100 meters per minute, and the cutting height on some machines reaches 2.5 meters. In addition, the master, working with a band saw, does not face such a problem as vibration.
Such devices do not require a massive base.
Finally, they consume a minimum amount of electricity.
Due to this, modern enterprises are switching to the use of band-type saws.
The teeth can have different shapes.
Saws, the tooth of which has a front angle of 0 degrees, are designed for cutting metal alloys with a high carbon content.
In addition, thin-walled metal profiles are sawn using these devices.
Saws, whose tooth has an angle of 10 degrees, are used for sawing steel pipes with thick walls.
Devices with teeth positioned at an angle of 16 degrees are designed for intensive sawing of bars made of steels, metals that are difficult to process, as well as non-ferrous alloys.
Finally, the tooth can have an anterior angle in two ways: 10 degrees and 16 degrees.
Such a saw can be used for cutting high-alloy steel.
Thus, by choosing the right band saw, you can quickly cut almost any material.
