What Is a Band Saw?
A Band Saw is a tool that cuts objects by rotating a band-shaped saw blade linked to a motor or other drive mechanism.
Since the saw blade is usually electrically driven and rotates in a fixed direction, it is characterized by a cleaner cutting surface and smoother operation compared to the use of ordinary saws.
Also, since the cutting width is determined by the blade thickness, it is necessary to have a variety of blade widths available.
Because of its high accuracy and work efficiency in cutting, it is one of the indispensable tools for woodworking, metalworking, etc.
Some blades, however, have rough cutting surfaces. However, some blades may cause rough cutting surfaces, so appropriate blade selection and regular maintenance are necessary.
Uses of Band Saw
Band saws are widely used in a variety of fields, including woodworking, metalworking, construction, and civil engineering. All types have the advantages of clean cutting surfaces and smooth operation compared to the use of ordinary saws.
1. Tabletop Horizontal Type
The horizontal tabletop type is suitable for cutting metal pipes, squares, plates, and round bars, and is characterized by its high cutting accuracy and smooth operation. It is also used for cutting wood and relatively thin boards.
2. Tabletop Vertical Type
The tabletop vertical type is suitable for cutting along curves, cutting small parts, and cutting relatively soft materials. Cutting curves can be difficult with other cutting tools, but with band saws, curves can be cut cleanly.
3. Portable Type
Portable types, most of which are rechargeable, are suitable for cutting materials in high places or materials that cannot be removed, or for working while facing up. They are characterized by their light weight and easy portability, making them ideal for use in field work.
4. With Casters
Caster types are usually large and suitable for cutting large-diameter pipes and large materials. Since they can easily cut even large materials, they are often used at construction and civil engineering sites.
Principle of Band Saw
Band saws cut materials by connecting a band-shaped saw blade to a motor or other drive system. The saw blade rotates like a belt, and a stage is attached to the cutting section to hold the material in place. The tabletop horizontal and tabletop vertical models are equipped with a cutting section that allows the user to apply the necessary force to cut the material for easy cutting.
The cutting capacity of a band saw is usually expressed in terms of the diameter of the pipe it can cut. Depending on the material, proper selection of saw blade material and blade shape may be necessary.
Unlike cutting materials by hand with a saw blade, the band saw cuts by rotating the saw blade in a constant direction, which requires relatively little force when cutting and results in a clean cut surface. Furthermore, by adjusting the rotation speed of the saw blade according to the material, an appropriate usage environment can be set to reduce the scattering of sparks and to prevent chips from spreading to the surrounding area.

Combination With Other Machines
Band Saws can be used efficiently in combination with other machines such as a Band Saw Guide, a Coolant Tank, a Band Saw Center, and a Band Saw Auto Feeder.
1. Band saw guide
A band saw guide is necessary to ensure accurate positioning of the band saw blade and stable cutting. By guiding the blade accurately, the band saw guide prevents distortion of the blade and improves cutting accuracy.
2. Coolant tank
Coolant is used to dissipate heat generated during cutting when using a band saw. The coolant tank supplies and circulates coolant to extend the life of the band saw and improve cutting accuracy.
3. Band saw center
A band saw center is necessary to ensure that the band saw is cutting at an accurate angle. The band saw center keeps the blade vertical while cutting at an accurate angle.
4. Band saw auto feeder
A band saw auto-feeder is needed to automate the band saw. The bandsaw auto-feeder automatically feeds material and performs continuous cutting, enabling mass production of products.
